  • s. Euclidean space
  • metric space
  • topological space
  • Physical space is the extension surrounding a point
  • My presentation of a general theory of living systems will employ two sorts of spaces in which they may exist, physical or geographical space and conceptual or abstracted spaces
  • Physical or geographical space
  • Euclidean space
  • distance
  • moving
  • maximum speed
  • objects moving in such space cannot pass through one another
  • friction
  • The characteristics and constraints of physical space affect the action of all concrete systems, living and nonliving.
  • information can flow worldwide almost instantly
  • Physical space is a common space
  • Most people learn that physical space exists, which is not true of many spaces
  • They can give the location of objects in it
  • Conceptual or abstracted spaces
  • Peck order
  • Social class space
  • Social distance
  • Political distance
  • life space
  • semantic space
  • Sociometric space
  • A space of time costs of various modes of transportation
  • space of frequency of trade relations among nations.
  • A space of frequency of intermarriage among ethnic groups.
  • These conceptual and abstracted spaces do not have the same characteristics and are not subject to the same constraints as physical space
  • Social and some biological scientists find conceptual or abstracted spaces useful because they recognize that physical space is not a major determinant of certain processes in the living systems they study
  • interpersonal relations
  • one cannot measure comparable processes at different levels of systems, to confirm or disconfirm cross-level hypotheses, unless one can measure different levels of systems or dimensions in the same spaces or in different spaces with known transformations among them
  • It must be possible, moreover, to make such measurements precisely enough to demonstrate whether or not there is a formal identity across levels

  • Matter and energy
  • Matter is anything which has mass (m) and occupies physical space.
  • Energy (E) is defined in physics as the ability to do work.
  • kinetic energy
  • potential energy
  • rest mass energy
  • Mass and energy are equivalent
  • Living systems need specific types of matter-energy in adequate amounts
  • Energy for the processes of living systems is derived from the breakdown of molecules
  • Any change of state of matter-energy or its movement over space, from one point to another, I shall call action.
  • It is one form of process.
  • information (H)
  • Transmission of Information
  • Meaning is the significance of information to a system which processes it: it constitutes a change in that system's processes elicited by the information, often resulting from associations made to it on previous experience with it
  • Information is a simpler concept: the degrees of freedom that exist in a given situation to choose among signals, symbols, messages, or patterns to be transmitted.
  • The set of all these possible categories (the alphabet) is called the ensemble or repertoire
  • .) The unit is the binary digit, or bit of information
  • . The amount of information is measured as the logarithm to the base 2 of the number of alternate patterns
  • Signals convey information to the receiving system only if they do not duplicate information already in the receiver. As Gabor says:
  • [The information of a message can] be defined as the 'minimum number of binary decisions which enable the receiver to construct the message, on the basis of the data already available to him.'
  • meaning cannot be precisely measured
  • Information is the negative of uncertainty.
  • information is the amount of formal patterning or complexity in any system.
  • The term marker was used by von Neumann to refer to those observable bundles, units, or changes of matter-energy whose patterning bears or conveys the informational symbols from the ensemble or repertoire.
  • If a marker can assume n different states of which only one is present at any given time, it can represent at most log2n bits of information. The marker may be static, as in a book or in a computer's memory
  • Communication of almost every sort requires that the marker move in space, from the transmitting system to the receiving system, and this movement follows the same physical laws as the movement of any other sort of matter-energy. The advance of communication technology over the years has been in the direction of decreasing the matter-energy costs of storing and transmitting the markers which bear information.
  • There are, therefore, important practical matter-energy constraints upon the information processing of all living systems exerted by the nature of the matter-energy which composes their markers.
  • organization is based upon the interrelations among parts.
  • If two parts are interrelated either quantitatively or qualitatively, knowledge of the state of one must yield some information about the state of the other. Information measures can demonstrate when such relationships exist
  • The disorder, disorganization, lack of patterning, or randomness of organization of a system is known as its entropy (S)
  • the statistical measure for the negative of entropy is the same as that for information
  • entropy becomes a measure of the probability
  • Increase of entropy was thus interpreted as the passage of a system from less probable to more probable states.
  • according to the second law, a system tends to increase in entropy over time, it must tend to decrease in negentropy or information.
  • therefore no principle of the conservation of information
  • The total information can be decreased in any system without increasing it elsewhere
  • but it cannot be increased without decreasing it elsewhere
  • . Making one or more copies of a given informational pattern does not increase information overall, though it may increase the information in the system which receives the copied information.
  • transforms information into negative entropy
  • smallest possible amount of energy used in observing one bit of information
  • calculations of the amount of information accumulated by living systems throughout growth.
  • the concept of Prigogine that in an open system (that is one in which both matter and energy can be exchanged with the environment) the rate of entropy production within the system, which is always positive, is minimized when the system is in a steady state.
  • in systems with internal feedbacks, internal entropy production is not always minimized when the system is in a stationary state. In other words, feedback couplings between the system parameters may cause marked changes in the rate of development of entropy. Thus it may be concluded that the "information flow" which is essential for this feedback markedly alters energy utilization and the rate of development of entropy, at least in some such special cases which involve feedback control. While the explanation of this is not clear, it suggests an important relationship between information and entropy
  • amount of energy actually required to transmit the information in the channel is a minute part of the total energy in the system, the "housekeeping energy" being by far the largest part of it
  • In recent years systems theorists have been fascinated by the new ways to study and measure information flows, but matter-energy flows are equally important. Systems theory is more than information theory, since it must also deal with energetics - such matters as
  • the flow of raw materials through societies
  • Only a minute fraction of the energy used by most living systems is employed for information processing
  • I have noted above that the movement of matter-energy over space, action, is one form of process. Another form of process is information processing or communication, which is the change of information from one state to another or its movement from one point to another over space
  • Communications, while being processed, are often shifted from one matter-energy state to another, from one sort of marker to another
  • transformations go on in living systems
  • One basic reason why communication is of fundamental importance is that informational patterns can be processed over space and the local matter-energy at the receiving point can be organized to conform to, or comply with, this information
  • the delivery of "flowers by telegraph."
  • Matter-energy and information always flow together
  • Information is always borne on a marker
  • . Conversely there is no regular movement in a system unless there is a difference in potential between two points, which is negative entropy or information
  • If the receiver responds primarily to the material or energic aspect, I shall call it, for brevity, a matter-energy transmission; if the response is primarily to the information, I shall call it an information transmission
  • Moreover, just as living systems must have specific forms of matter-energy, so they must have specific patterns of information
  • example
  • example
  • develop normally
  • have appropriate information inputs in infancy
  • pairs of antonyms
  • one member of which is associated with the concept of information (H)
  • the other member of which is associated with its negative, entropy (S)
  • System
  • A system is a set of interacting units with relationships among them
  • .The word "set" implies that the units have some common properties. These common properties are essential if the units are to interact or have relationships. The state of each unit is constrained by, conditioned by, or dependent on the state of other units. The units are coupled. Moreover, there is at least one measure of the sum of its units which is larger than the sum of that measure of its units.

  • Indicator
  • an instrument or technique used to measure fluctuations of variables in concrete systems
  • Function
  • a correspondence between two variables, x and y, such that for each value of x there is a definite value of y, and no two y's have the same x, and this correspondence is: determined by some rule

  • The state of a conceptual system
  • the set of values on some scale, numerical or otherwise, which its variables have at a given instant
  • Formal identity
  • variables
  • varies comparably to a variable in another system
  • If these comparable variations are so similar that they can be expressed by the same function, a formal identity exists between the two systems
  • Relationships between conceptual and other sorts of systems
  • Science advances as the formal identity or isomorphism increases between a theoretical conceptual system and objective findings about concrete or abstracted systems
  • A conceptual system may be purely logical or mathematical, or its terms and relationships may be intended to have some sort of formal identity or isomorphism with units and relationships empirically determinable by some operation carried out by an observer
  • Concrete system
  • a nonrandom accumulation of matter-energy, in a region in physical space-time, which is organized into interacting interrelated subsystems or components.
  • Units

  • causal
  • Both units and relationships in concrete systems are empirically determinable by some operation carried out by an observer
  • patterns of relationships or processes
  • The observer of a concrete system
  • distinguishes a concrete system from unorganized entities in its environment by the following criteria
  • physical proximity of its units
  • similarity of its units
  • common fate of its units
  • distinct or recognizable patterning of its units.
  • Their boundaries are discovered by empirical operations available to the general scientific community rather than set conceptually by a single observer
  • Variable of a concrete system
  • Any property of a unit or relationship within a system which can be recognized by an observer
  • which can potentially change over time, and whose change can potentially be measured by specific operations, is a variable of a concrete system
  • Examples
  • number of its subsystems or components, its size, its rate of movement in space, its rate of growth, the number of bits of information it can process per second, or the intensity of a sound to which it responds
  • A variable is intrasystemic
  • not to be confused with intersystemic variations which may be observed among individual systems, types, or levels.
  • The state of a concrete system
  • its structure
  • represented by the set of values on some scale which its variables have at that instant
  • Open system
  • Most concrete systems have boundaries which are at least partially permeable, permitting sizable magnitudes of at least certain sorts of matter-energy or information transmissions to pass them. Such a system is an open system. In open systems entropy may increase, remain in steady state, or decrease.
  • Closed system
  • impermeable boundaries through which no matter-energy or information transmissions of any sort can occur is a closed system
  • special case
  • No actual concrete system is completely closed
  • In closed systems, entropy generally increases, exceptions being when certain reversible processes are carried on which do not increase it. It can never decrease.
  • Nonliving system
  • the general case of concrete systems, of which living systems are a very special case. Nonliving systems need not have the same critical subsystems as living systems, though they often have some of them
  • Living system
  • a special subset of the set of all possible concrete systems
  • They all have the following characteristics:
  • open systems
  • inputs
  • throughputs
  • outputs
  • of various sorts of matter-energy and information.
  • maintain a steady state of negentropy even though entropic changes occur in them as they do everywhere else
  • by taking in inputs
  • higher in complexity or organization or negentropy
  • than their outputs
  • The difference permits them to restore their own energy and repair breakdowns in their own organized structure.
  • In living systems many substances are produced as well as broken down
  • To do this such systems must be open and have continual inputs of matter-energy and information
  • entropy will always increase in walled-off living systems

  • or have a charter
  • blueprint
  • program
  • of their structure and process from the moment of their origin
  • may also include nonliving components.
  • They have a decider, the essential critical sub-system which controls the entire system, causing its subsystems and components to interact. Without such interaction under decider control there is no system.
  • other specific critical sub-systems or they have symbiotic or parasitic relationships with other living or nonliving systems

  • Some relationships may be empirically determinable by some operation carried out by the observer, but others are not, being only his concepts
  • Relationships
  • The relationships mentioned above are observed to inhere and interact in concrete, usually living, systems
  • these concrete systems are the relationships of abstracted systems.
  • The verbal usages of theoretical statements concerning abstracted systems are often the reverse of those concerning concrete systems
  • An abstracted system differs from an abstraction, which is a concept
  • representing a class of phenomena all of which are considered to have some similar "class characteristic." The members of such a class are not thought to interact or be interrelated, as are the relationships in an abstracted system

  • we propose to identify social hierarchies not by observing who lives close to whom but by observing who interacts with whom
  • intensity of interaction
  • in most biological and physical systems relatively intense interaction implies relative spatial propinquity
  • To the extent that interactions are channeled through specialized communications and transportation systems, spatial propinquity becomes less determinative of structure.

  • The social system is the actual habitual network of communication between people.
  • RUESCH
  • A social system is a behavioral system
  • It is an organized set of behaviors of persons interacting with each other: a pattern of roles.
  • The roles are the units of a social system
    • Tiberius Brastaviceanu
       
      That is why we need a role system in SENSORICA
  • On the other hand, the society is an aggregate of social subsystems, and as a limiting case it is that social system which comprises all the roles of all the individuals who participate.
  • What Ruesch calls the social system is something concrete in space-time, observable and presumably measurable by techniques like those of natural science
  • To Parsons the system is abstracted from this, being the set of relationships which are the form of organization. To him the important units are classes of input-output relationships of subsystems rather than the subsystems themselves
  • system is a system of relationship in action, it is neither a physical organism nor an object of physical perception
  • evolution
  • differentiation
  • growth
  • from earlier and simpler forms and functions
  • capacities for specializations and gradients
  • [action] is not concerned with the internal structure of processes of the organism, but is concerned with the organism as a unit in a set of relationships and the other terms of that relationship, which he calls situation
  • Abstracted versus concrete systems
  • One fundamental distinction between abstracted and concrete systems is that the boundaries of abstracted systems may at times be conceptually established at regions which cut through the units and relationships in the physical space occupied by concrete systems, but the boundaries of these latter systems are always set at regions which include within them all the units and internal relationships of each system
  • A science of abstracted systems certainly is possible and under some conditions may be useful.
  • If the diverse fields of science are to be unified, it would be helpful if all disciplines were oriented either to concrete or to abstracted systems.
  • It is of paramount importance for scientists to distinguish clearly between them

Guidelines on Measuring Subjective Well-being.pdf - 0 views

  • such as interest,engagement and meaning,
  • subjective well-being is taken to be:2Good mental states, including all of the various evaluations, positive and negative, that peoplemake of their lives, and the affective reactions of people to their experiences
  • “subjective well-being is an umbrella term for the different valuationspeople make regarding their lives, the events happening to them, their bodies and minds,and the circumstances in which they live”.
  • ...16 more annotations...
  • In measuring overall human well-being then, subjective well-being should be placedalongside measures of non-subjective outcomes, such as income, health, knowledge andskills, safety, environmental quality and social connections
  • Inparticular, a distinction is commonly made between life evaluations, which involve acognitive evaluation of the respondent’s life as a whole (or aspects of it), and measures ofaffect, which capture the feelings experienced by the respondent at a particular point in time(Diener, 1984; Kahneman et al., 1999
  • eudaimonic aspect ofsubjective well-being, reflecting people’s sense of purpose and engagement
  • The framework used here covers all three concepts of well-being:●Life evaluation.●Affect.●Eudaimonia (psychological “flourishing”)
  • the result of a judgement by the individual rather than thedescription of an emotional state.
  • Elements of subjective well-beingLife evaluation
  • making an evaluation of this sort as involving the individual constructing a “standard” thatthey perceive as appropriate for themselves, and then comparing the circumstances oftheir life to that standard
  • Life evaluations are based on how people remember their experiences (Kahneman et al.,1999) and can differ significantly from how they actually experienced things at the time
  • It is for this reason that life evaluations are sometimes characterised as measures of“decision utility” in contrast to “experienced utility”
  • One of the mostwell documented measures of life evaluation – thePersonal Wellbeing Index– consists of eightquestions, covering satisfactions with eight different aspects of life, which are summedusing equal weights to calculate an overall index (International Wellbeing Group, 2006)
  • (job satisfaction, financial satisfaction, house satisfaction, healthsatisfaction, leisure satisfaction and environmental satisfaction),
  • AffectAffect is the term psychologists use to describe a person’s feelings. Measures of affectcan be thought of as measures of particular feelings or emotional states, and they aretypically measured with reference to a particular point in time.
  • Such measures capturehow people experience life rather than how they remember it (Kahneman and Krueger,2006
  • While an overall evaluation of life can be captured in a single measure, affect has atleast two distinct hedonic dimensions: positive affect and negative affect (Kahneman et al.,1999; Diener et al., 1999
  • positive affect is thought to be largely uni-dimensional
  • negative affect may be more multi-dimensional.

Welcome to the new reputation economy (Wired UK) - 1 views

  • banks take into account your online reputation alongside traditional credit ratings to determine your loan
  • headhunters hire you based on the expertise you've demonstrated on online forums
  • reputation data becomes the window into how we behave, what motivates us, how our peers view us and ultimately whether we can or can't be trusted.
  • ...37 more annotations...
  • At the heart of Movenbank is a concept call CRED.
  • The difference today is our ability to capture data from across an array of digital services. With every trade we make, comment we leave, person we "friend", spammer we flag or badge we earn, we leave a trail of how well we can or can't be trusted.
  • An aggregated online reputation having a real-world value holds enormous potential
  • peer-to-peer marketplaces, where a high degree of trust is required between strangers; and where a traditional approach based on disjointed information sources is currently inefficient, such as recruiting.
  • opportunity to reinvent the way people found jobs through online reputation
  • "It's not about your credit, but your credibility," King says.
  • But this wealth of data raises an important question -- who owns our reputation? Shouldn't our hard-earned online status be portable? If you're a SuperHost on Airbnb, shouldn't you be able to use that reputation to, say, get a loan, or start selling on Etsy?
  • "People are currently underusing their networks and reputation," King says. "I want to help people to understand and build their influence and reputation, and think of it as capital they can put to good use."
  • Social scientists have long been trying to quantify the value of reputation.
  • Using functional magnetic resonance imaging, the researchers monitored brain activity
  • "The implication of our study is that different types of reward are coded by the same currency system." In other words, our brains neurologically compute personal reputation to be as valuable as money.
  • Personal reputation has been a means of making socioeconomic decisions for thousands of years. The difference today is that network technologies are digitally enabling the trust we used to experience face-to-face -- meaning that interactions and exchanges are taking place between total strangers.
  • Trust and reputation become acutely important in peer-to-peer marketplaces such as WhipCar and Airbnb, where members are taking a risk renting out their cars or their homes.
  • When you are trading peer-to-peer, you can't count on traditional credit scores. A different measurement is needed. Reputation fills this gap because it's the ultimate output of how much a community trusts you.
  • Welcome to the reputation economy, where your online history becomes more powerful than your credit history.
  • Presently, reputation data doesn't transfer between verticals.
  • A wave of startups, including Connect.Me, TrustCloud, TrustRank, Legit and WhyTrusted, are trying to solve this problem by designing systems that correlate reputation data. By building a system based on "reputation API" -- a combination of a user's activity, ratings and reviews across sites -- Legit is working to build a service that gives users a score from zero to 100. In trying to create a universal metric for a person's trustworthiness, they are trying to "become the credit system of the sharing economy", says Jeremy Barton, the 27-year-old San Francisco-based cofounder of Legit.
  • His company, and other reputation ventures, face some big challenges if they are to become, effectively, the PayPal of trust. The most obvious is coming up with algorithms that can't be easily gamed or polluted by trolls. And then there's the critical hurdle of convincing online marketplaces not just to open up their reputation vaults, but create a standardised format for how they frame and collect reputation data. "We think companies will share reputation data for the same reasons banks give credit data to credit bureaux," says Rob Boyle, Legit cofounder and CTO. "It is beneficial for one company to give up their slice of reputation data if in return they get access to the bigger picture: aggregated data from other companies."
  • PeerIndex, Kred and Klout,
  • are measuring social influence, not reputation. "Influence measures your ability to drag someone into action,"
  • "Reputation is an indicator of whether a person is good or bad and, ultimately, are they trustworthy?"
  • Early influence and reputation aggregators will undoubtedly learn by trial and error -- but they will also face the significant challenge of pioneering the use of reputation data in a responsible way. And there's a challenge beyond that: reputation is largely contextual, so it's tricky to transport it to other situations.
  • Many of the ventures starting to make strides in the reputation economy are measuring different dimensions of reputation.
  • reputation is a measure of knowledge
  • a measure of trust
  • a measure of propensity to pay
  • measure of influence
  • Reputation capital is not about combining a selection of different measures into a single number -- people are too nuanced and complex to be distilled into single digits or binary ratings.
  • It's the culmination of many layers of reputation you build in different places that genuinely reflect who you are as a person and figuring out exactly how that carries value in a variety of contexts.
  • The most basic level is verification of your true identity
  • reliability and helpfulness
  • do what we say we are going to do
  • respect another person's property
  • trusted to pay on time

Conference Detail for Industrial and Commercial Applications of Smart Structures Techno... - 0 views

  •  
    "Three-axis distributed fiber optic strain measurement in 3D woven composite structures   Paper 8690-6 Time: 1:50 PM - 2:10 PM Author(s): Matt Castellucci, Evan M. Lally, Sandra Klute, Luna Innovations Inc. (United States); David Lowry, NASA Johnson Space Ctr. (United States) Hide Abstract Add to My Schedule  Recent advancements in composite materials technologies have broken further from traditional designs and require advanced instrumentation and analysis capabilities. Success or failure is highly dependent on design analysis and manufacturing processes. By monitoring smart structures throughout manufacturing and service life, residual and operational stresses can be assessed and structural damage identified. Composite smart structures can be manufactured by integrating fiber optic sensors into existing composite materials processes such as layup, filament winding and three-dimensional weaving. In this work optical fiber was integrated into 3D woven composite parts at a commercial woven products manufacturing facility. The fiber was then used to monitor the structures during a VARTM manufacturing process, and subsequent static and dynamic testing. Low cost telecommunications-grade optical fiber acts as the sensor using a high resolution commercial Optical Frequency Domain Reflectometer (OFDR) system providing distributed strain measurement at spatial resolutions as low as 2mm. Strain measurements using the optical fiber sensors are correlated to resistive strain gauge measurements during static structural loading."

  • Modern education is a typical effort that people are trying to make a product line of high-quality mind asset.
  • Without explicit, formal presentation of mind asset, we cannot efficiently connect and compose varied mind asset and we cannot well measure the value of mind asset. The issue of mind aggregation is particularly critical because individual mind is often too shallow to be high quality.
  • There is a natural gap between the presented value of the mind asset in the book and the real value of the mind asset in real world. This gap of knowledge understanding is a typical difficulty of mind asset measurement.

Scientist beams up a real Star Trek tricorder | Reuters - 1 views

  •  
    While it may sound like the stuff of science fiction, Jansen isn't the only one to take notice of just how useful a real functioning tricorder would be - especially as a medical tool. Telecommunications giant Qualcomm Inc this year launched the "Tricorder X-Prize Contest" with the slogan "Healthcare in the palm of your hand." Qualcomm hopes to motivate developers with a $10 million prize to make medical tricorders a reality. Wanda Moebus of the Advanced Medical Technology Association, who is not affiliated with Jansen or Qualcomm, told Reuters the X-Prize "is really cool," but cautioned that making a real medical tricorder device "would have to be measured on its safety and effect, like all other medical technologies." Jansen said he has been approached by "a couple of teams" about the X Prize, but added that his prototypes are more for science research than medical tools. Besides, he said he already is on to his next frontier, making a sort of "replicator," another "Star Trek" device that will create 3D objects and foods that are dimensional copies of real items. Jansen's "replicator" is a 3D printer, which in itself is not really new, but the scientist thinks about it in terms reminiscent of "Star Trek's" famous prologue. It's "like nothing we've ever seen before," Jansen said.

Value Creating Service Systems: From Service Systems to Digital Lives - 0 views

    "Service dominant logic suggest that value is always co-created in context of use and experience. Co-creation is not an option (Vargo and Lusch, 2004, 2008). "Moving things along meant a focus on 2 key aspects. philosophy and methods. "An SD logic approach is not one that you can run a survey of attitude, behaviours or intentions. The person is embedded in his actions and practices of value creation. The focus on context means the unit of analysis is in the sociology of real life behaviours. A sociological approach makes methods a problem because we've inherited a world where we have created tools from analysing water in a bucket, not by looking at its behaviour in a river. "GD logic is compelling not only because it is entrenched for over 500 years, but also because you could measure its constructs. GDP, sales, revenues, CPI - they are all constructs of a GD logic society. What SD logic needed was better methods and new constructs. "To that end, and rather ironically, I found an ally in digital technology. Here was a world of sensors and actuators with an enthusiastic community looking for novel ways of deploying them into homes and buildings i.e. the internet-of-things. "I also found, as an ally, the thinking around new economic and business models. Here was another strand of literature largely marginalised by mainstream business literature because it was (the way I interpreted it) taking a systemic view of value proposition, value creation and value capture (ie, change one, change all) and the way the organisation had to be agile and transformed for it - which sat very nicely with SD logic. "Customised products are firm centric. Personalised products are customer initiated and empowering. Personalised products also tend to move the product into becoming platforms to afford co-creation, which advanced the notion of symmetry in value co-creation further. Finally, with the advent of platforms, the economics of 2 or multi-sided markets completed my set of theoretica

  • The system is not made up of artifacts but rather an elegantly designed void. He says “I prefer to use the analogy of rescuing an endangered species from extinction, rather than engaging in an invasive breeding program the focus should be on the habitat that supports the species. Careful crafting of the habitat by identifying the influential factors; removing those that are detrimental, together with reinforcing those that are encouraging, the species will naturally re-establish itself. Crafting the habitat is what I mean by designing the void.”

  • It is essential that autonomy is combined with responsibility.
  • staff typically manage the whole work process from making sales, manufacture, accounts, to dispatch
  • they are also responsible for managing their own capitalization; a form of virtual ownership develops. Everything they need for their work, from office furniture to high-end machinery will appear on their individual balance sheet; or it will need to be bought in from somewhere else in the company on a pay-as-you go or lease basis. All aspects of the capital deployed in their activities must be accounted for and are therefore treated with the respect one accords one’s own property.

  • The result is not simply a disparate set of individuals doing their own thing under the same roof. Together they benefit from an economy of scale as well as their combined resources to tackle large projects; they are an interconnected whole. They have in common a brand, which they jointly represent, and also a business management system (the Say-Do-Prove system) - consisting not only of system-wide boundaries but also proprietary business management software which helps each take care of the back-end accounting and administrative processing. The effect is a balance between freedom and constraint, individualism and social process.
  • embodiment of meaning
  • But culture is a much more personal phenomenon
  • Culture is like climate- it does not exist in and of itself- it cannot exist in a vacuum, it must exist within a medium.
  • underlying culture
  • Incompatibility between the presenting culture and the underlying one provide a great source of tension
  • The truth of course is that when tension builds to a critical level it takes just a small perturbation to burst the bubble and the hidden culture reveals itself powered by the considerable pent-up energy.

  • Consider again the idea that for the health of an endangered species; the conditions in their habitat must be just right. In business, the work environment can be considered analogous to this idea of habitat.
  • A healthy environment is one that provides a blank canvas; it should be invisible in that it allows culture to be expressed without taint
  • The over-arching, high-level obligations are applied to the organization via contractual and legal terms.
  • But it is these obligations that the traditional corporate model separates out into functions and then parcels off to distinct groups. The effect is that a clear sight of these ‘higher’ obligations by the people at the front-end is obstructed. The overall sense of responsibility is not transmitted but gets lost in the distortions, discontinuities and contradictions inherent in the corporate systems of hierarchy and functionalization.
  • employees are individually rewarded for their contribution to each product. They are not “compensated” for the hours spent at work. If an employee wants to calculate their hourly rate, then they are free to do so however, they are only rewarded for the outcome not the duration of their endeavors.
  • Another simplification is the application of virtual accounts (Profit and Loss (P&L) account and Balance Sheet) on each person within the business.
  • The company systems simply provide a mechanism for cheaply measuring the success of each individual’s choices. For quality the measure is customer returns, for delivery it is an on-time-and-in-full metric and profit is expressed in terms of both pounds sterling and ROI (return on investment).

  • The innumerable direct links back to an external reality -like the fragile ties that bound giant Gulliver, seem much more effective at aligning the presenting culture and the underlying embodied culture, and in doing so work to remove the existing tension.
  • With a culture that responds directly to reality, the rules in the environment can be “bounding” rather than “binding”- limiting rather than instructive; this way individual behavior need not be directed at all. The goal is to free the individual to express himself fully through his work, bounded only by the limits of the law. With clever feedback (self-referencing feedback loops) integrated into the design, the individuals can themselves grow to collectively take charge of the system boundaries, culture and even the environment itself, always minded of the inherent risks they are balancing, leaving the law of the land as the sole artificial boundary.
  • the conventional company, which, instead of rewarding enterprise, trains compliance by suppressing individual initiative under layer upon layer of translation tools.
  • apply accountability to the individual not command-and-control.
  • without the divisive and overbearing management cabal the natural reaction of humans is to combine their efforts
  • a new member of staff at Matt Black Systems
  • recruited by another staff member (sponsor) and they will help you learn the basics of the business management system- they will help you get to know the ropes.
  • jobs are passed to new staff members, a royalty payment can be established on the work passed over.
  • Along with that job you will be given a cash float (risk capital), P&L Account, a Balance Sheet and computer software to help plan and record your activities. Your operation is monitored by your sponsor to see if you increase the margin or volume, and so establish a sustainable operation. Training and mentoring is provided to support the steep learning curve - but without removing the responsibility of producing a return on the sponsor’s risk capital.
  • You will, in the meantime be looking to establish some of your own work for which you will not have to pay a commission or royalty to your sponsor and this will provide you with more profitable operations such that eventually you might pass back to the sponsor the original operation, as it has become your lowest margin activity. It will then find its way to a new employee (along with the associated Balance Sheet risk capital) where the process is repeated by the sponsor.[4]
  • Remuneration for staff is calibrated in a way that reflects the balance of different forces around ‘pay’
  • there is an obligation upon the company to pay a minimum wage even if the profitability of the operation does not support this
  • there are therefore two aspects of the basic pay structure: one is “absolute” and reflects the entrepreneurial skill level of the employee according to a sophisticated grading scale
  • A further 20% of the original profit will be paid into his risk capital account, which will be his responsibility to deploy in any way he sees fit as part of his Balance Sheet. Of the three remaining 20% slices of the original profit, one is paid out as corporation tax, another as a dividend to the shareholders and the last retained as collective risk capital on the company’s balance sheet- a war chest so to speak.
  • Julian Wilson and Andrew Holm sell products / services to their staff (such as office space and software) they have an identical customer/supplier relationship with the other employees.
  • Naturally there are some people that can’t generate a profit. The sponsor’s risk capital will eventually be consumed through pay. After a process of rescue and recovery- where their shortcomings are identified and they are given the opportunity to put them right, they either improve or leave, albeit with a sizeable increase in their skills.
  • there is a gradual process of accustomisation; the void of the new employee is surrounded by others dealing with their particular activities, offering both role models and operations they may wish to relinquish. One step at a time the new employee acquires the skills to become completely self-managing, to increase their margins, to make investments, to find new business, to become a creator of their own success. Ultimately, they learn to be an entrepreneur.
  • responsible autonomy as an alternative vision to traditional hierarchy
  • Matt Black Systems it is not simply commitment that they targeted in their employees, rather they aim for the specific human qualities they sum up as magic- those of curiosity, imagination, creativity, cooperation, self-discipline and realization (bringing ideas to reality).
  • a new form of association of individuals working together under the umbrella of a company structure: a kind of collective autonomy
  • The business is called Matt Black Systems, based in Poole in dorset
  • Turning an organisation on its head- removing all management, establishing a P&L account and Balance Sheet on everyone in the organisation and having customers payment go first into the respective persons P&L account has revolutionised this company. 
  • This innovative company’s approach views business success as wholly reliant upon human agency, and its wellspring at the individual level.
  • problem (of unnecessarily high overheads placed on production) that arguably is behind the decline in western manufacturing
  • over-managed business
  • Autonomy Enables Productivity
  • organizational design brings to light the unconscious socio-philosophical paradigm of the society in which it exists, organizational development points to how change occurs.
  • a mechanistic approach to organization
  • scientific management employs rationalism and determinism in pursuit of efficiency, but leaves no place for self-determination for most people within the system.
  • Command and Control
  • today, a really “modern” view of an organization is more likely to be depicted in terms that are akin to an organism.
  • When it comes to getting work done, the simple question is: are people the problem or the solution?
  • the Taylorist approach may be more real in theory than in practice: its instrumentalist view of the workforce is cursed by unintended consequences. When workers have no space for their own creative expression, when they are treated like automata not unique individuals, when they become demotivated and surly, when they treat their work as a necessary evil; this is no recipe for a functional organization.
  • The natural, human reaction to this is unionization, defiance and even outright rebellion; to counter this, management grows larger and more rigid in pursuit of compliance, organizations become top heavy with staff who do not contribute directly to the process of value creation but wield power over those who do.
  • voluntary slavery of ‘wagery’
  • Even when disgruntled employees strike free and start their own businesses they seem unable to resist the hegemony of the conventional command-and-control approach
  • Making the transition involves adherence to a whole new sociology of work with all the challenging social and psychological implications that brings.
  • first principal that people in the business have the ability to provide the solution
  • In the “theory of constraints” the goal is to align front-line staff into a neat, compact line for maximum efficiency. Surely the most considered approach is to have front-line staff self-align in pursuit of their individual goals?
  • The removal of hierarchy and specialization is key to a massive improvement in both profitability and productivity. In summary: there are no managers in the company, or foremen, or sales staff, or finance departments; the company is not functionally compartmentalized and there is no hierarchy of command. In fact every member of staff operates as a virtual micro-business with their own Profit & Loss account and Balance Sheet, they manage their own work and see processes through from end to end
  • Formal interaction between colleagues takes place via “customer and supplier” relationships.
  • autonomy enables productivity
  • if one creates a space in which staff pursue their own goals and are not paid by the hour, they will focus on their activities not the clock; if they are not told what to do, they will need to develop their own initiative; if they are free to develop their own processes, they will discover through their own creative faculties how to work more productively- in pursuit of their goals
  • The human qualities which are of greatest potential value to the business are: curiosity, imagination, creativity, cooperation, self-discipline and realization (bringing ideas to reality)
  • These qualities are the very ones most likely to be withheld by an individual when the environment is ‘wrong’.
  • Any elements in the business environment that undermine the autonomy and purpose of the individual will see the above qualities withheld
  • High on the list of undermining elements come power-hierarchy and over-specialization
  • the responsibility of the individual is formalized, specified and restricted. An improved system is not one where responsibility is distributed perfectly but rather one where there is simply no opportunity for responsibility to be lost (via the divisions between the chunks). Systems must be reorganized so responsibility -the most essential of qualities -is protected and wholly preserved.
  • Matt Black Systems believe this can only be done by containing the whole responsibility within an individual, holding them both responsible and giving them ‘response-ability’
  • The experience of Matt Black Systems demonstrates that radical change is possible
  • productivity is up 300%, the profit margin is up 10%[3], customer perception has shifted from poor to outstanding, product returns are at less than 1%, “on time and in full” delivery is greater than 96%, pay has increased 100%.
  • staff develop broader and deeper skills and feel greater job security; they get direct feedback from their customers which all go to fuel self-confidence and self-esteem.
  • the staff manage themselves
  • “only variety can absorb variety”.
  • What is particular about their story is that behind it is a very consciously crafted design that surrounds the individualism of each person with hard boundaries of the customer, the law and the business. It is these boundaries rather than the instructive persona of ‘the boss’ that gives rise to the discipline in which individuals can develop. Autonomy is not the same as freedom, at least not in the loose sense of ‘do as you please’. An autonomous person is a person who has become self-governing, who has developed a capacity for self-regulation, quite a different notion from the absence of boundaries. Indeed, it is with establishing the right boundaries that the business philosophy is most concerned. The company provides the crucible in which the individual can develop self-expression but the container itself is bounded. Wilson calls this “designing the void”. This crucible is carefully constructed from an all-encompassing, interconnecting set of boundaries that provide an ultimate limit to behaviours (where they would fall foul of the law or take risks with catastrophic potential). It is an illusion to think, as a director of a company, that you are not engaged in a process of social conditioning; the basis of the culture is both your responsibility and the result of your influence. The trick is to know what needs to be defined and what needs to be left open. The traditional authoritarian, controlling characters that often dominate business are the antithesis of this in their drive to fill this void with process, persona and instruction. Alternatively, creating an environment that fosters enterprise, individuals discover how to be enterprising.
