valve management structure company paper

shared by Kurt Laitner on 07 Aug 12 - No Cached
  • Valve’s management model; one in which there are no bosses, no delegation, no commands, no attempt by anyone to tell someone what to do
  • Every social order, including that of ants and bees, must allocate its scarce resources between different productive activities and processes, as well as establish patterns of distribution among individuals and groups of output collectively produced.
  • the allocation of resources, as well as the distribution of the produce, is based on a decentralised mechanism functioning by means of price signals:
  • ...18 more annotations...
  • Interestingly, however, there is one last bastion of economic activity that proved remarkably resistant to the triumph of the market: firms, companies and, later, corporations. Think about it: market-societies, or capitalism, are synonymous with firms, companies, corporations. And yet, quite paradoxically, firms can be thought of as market-free zones. Within their realm, firms (like societies) allocate scarce resources (between different productive activities and processes). Nevertheless they do so by means of some non-price, more often than not hierarchical, mechanism!
  • they are the last remaining vestiges of pre-capitalist organisation within… capitalism
  • The miracle of the market, according to Hayek, was that it managed to signal to each what activity is best for herself and for society as a whole without first aggregating all the disparate and local pieces of knowledge that lived in the minds and subconscious of each consumer, each designer, each producer. How does this signalling happen? Hayek’s answer (borrowed from Smith) was devastatingly simple: through the movement of prices
  • The idea of spontaneous order comes from the Scottish Enlightenment, and in particular David Hume who, famously, argued against Thomas Hobbes’ assumption that, without some Leviathan ruling over us (keeping us “all in awe”), we would end up in a hideous State of Nature in which life would be “nasty, brutish and short”
  • Hume’s counter-argument was that, in the absence of a system of centralised command, conventions emerge that minimise conflict and organise social activities (including production) in a manner that is most conducive to the Good Life
  • Hayek’s argument was predicated upon the premise that knowledge is always ‘local’ and all attempts to aggregate it are bound to fail. The world, in his eyes, is too complex for its essence to be distilled in some central node; e.g. the state.
  • The idea here is that, through this ever-evolving process, people’s capacities, talents and ideas are given the best chance possible to develop and produce synergies that promote the Common Good. It is as if an invisible hand guides Valve’s individual members to decisions that both unleash each person’s potential and serve the company’s collective interest (which does not necessarily coincide with profit maximisation).
  • Valve differs in that it insists that its employees allocate 100% of their time on projects of their choosing
  • In contrast, Smith and Hayek concentrate their analysis on a single passion: the passion for profit-making
  • Hume also believed in a variety of signals, as opposed to Hayek’s exclusive reliance on price signalling
  • One which, instead of price signals, is based on the signals Valve employees emit to one another by selecting how to allocate their labour time, a decision that is bound up with where to wheel their tables to (i.e. whom to work with and on what)
  • He pointed out simply and convincingly that the cost of subcontracting a good or service, through some market, may be much larger than the cost of producing that good or service internally. He attributed this difference to transactions costs and explained that they were due to the costs of bargaining (with contractors), of enforcing incomplete contracts (whose incompleteness is due to the fact that some activities and qualities cannot be fully described in a written contract), of imperfect monitoring and asymmetrically distributed information, of keeping trade secrets… secret, etc. In short, contractual obligations can never be perfectly stipulated or enforced, especially when information is scarce and unequally distributed, and this gives rise to transaction costs which can become debilitating unless joint production takes place within the hierarchically structured firm. Optimal corporation size corresponds, in Coase’s scheme of things, to a ‘point’ where the net marginal cost of contracting out a service or good (including transaction costs) tends to zero 
  • As Coase et al explained in the previous section, the whole point about a corporation is that its internal organisation cannot turn on price signals (for if it could, it would not exist as a corporation but would, instead, contract out all the goods and services internally produced)
  • Each employee chooses (a) her partners (or team with which she wants to work) and (b) how much time she wants to devote to various competing projects. In making this decision, each Valve employee takes into account not only the attractiveness of projects and teams competing for their time but, also, the decisions of others.
  • Hume thought that humans are prone to all sorts of incommensurable passions (e.g. the passion for a video game, the passion for chocolate, the passion for social justice) the pursuit of which leads to many different types of conventions that, eventually, make up our jointly produced spontaneous order
  • Valve is, at least in one way, more radical than a traditional co-operative firm. Co-ops are companies whose ownership is shared equally among its members. Nonetheless, co-ops are usually hierarchical organisations. Democratic perhaps, but hierarchical nonetheless. Managers may be selected through some democratic or consultative process involving members but, once selected, they delegate and command their ‘underlings’ in a manner not at all dissimilar to a standard corporation. At Valve, by contrast, each person manages herself while teams operate on the basis of voluntarism, with collective activities regulated and coordinated spontaneously via the operations of the time allocation-based spontaneous order mechanism described above.
  • In contrast, co-ops and Valve feature peer-based systems for determining the distribution of a firm’s surplus among employees.
  • There is one important aspect of Valve that I did not focus on: the link between its horizontal management structure and its ‘vertical’ ownership structure. Valve is a private company owned mostly by few individuals. In that sense, it is an enlightened oligarchy: an oligarchy in that it is owned by a few and enlightened in that those few are not using their property rights to boss people around. The question arises: what happens to the alternative spontaneous order within Valve if some or all of the owners decide to sell up?

    "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.

paper Ethereum

shared by Kurt Laitner on 11 Feb 14 - No Cached
  • The general concept of a "decentralized autonomous organization" is that of a virtual entity that has a certain set of members or shareholders which, perhaps with a 67% majority, have the right to spend the entity's funds and modify its code. The members would collectively decide on how the organization should allocate its funds. Methods for allocating a DAO's funds could range from bounties, salaries to even more exotic mechanisms such as an internal currency to reward work. This essentially replicates the legal trappings of a traditional company or nonprofit but using only cryptographic blockchain technology for enforcement. So far much of the talk around DAOs has been around the "capitalist" model of a "decentralized autonomous corporation" (DAC) with dividend-receiving shareholders and tradable shared; an alternative, perhaps described as a "decentralized autonomous community", would have all members have an equal share in the decision making and require 67% of existing members to agree to add or remove a member. The requirement that one person can only have one membership would then need to be enforced collectively by the group.

  • DAOs and DACs have already been the topic of a large amount of interest among cryptocurrency users as a future form of economic organization, and we are very excited about the potential that DAOs can offer. In the long term, the Ethereum fund itself intends to transition into being a fully self-sustaining DAO.
  • In Bitcoin, there are no mandatory transaction fees.
  • In Ethereum, because of its Turing-completeness, a purely voluntary fee system would be catastrophic. Instead, Ethereum will have a system of mandatory fees, including a transaction fee and six fees for contract computations.
  • The coefficients will be revised as more hard data on the relative computational cost of each operation becomes available. The hardest part will be setting the value of
  • There are currently two main solutions that we are considering: Make x inversely proportional to the square root of the difficulty, so x = floor(10^21 / floor(difficulty ^ 0.5)). This automatically adjusts fees down as the value of ether goes up, and adjusts fees down as computers get more powerful due to Moore's Law. Use proof of stake voting to determine the fees. In theory, stakeholders do not benefit directly from fees going up or down, so their incentives would be to make the decision that would maximize the value of the network.

property governance paper

shared by Kurt Laitner on 03 Feb 14 - No Cached
  • Whenever a group of people depend on a resource that everybody uses but nobody owns, and where one person’s use effects another person’s ability to use the resource, either the population fails to provide the resource, overconsumes and/or fails to replenish it, or they construct an institution for undertaking and managing collective action.
  • Common-pool resources may be owned by national, regional, or local [1]governments; by [2] communal groups; by [3] private individuals or corporations; or used as open access resources by whomever can gain access
  • Based on her survey, Ostrom distilled this list of common design principles from the experience of successful governance institutions: Clearly defined boundaries. Individuals or households who have rights to withdraw resource units from the CPR must be clearly defined, as must the boundaries of the CPR itself. Congruence between appropriation and provision rules and local conditions. Appropriation rules restricting time, place, technology, and/or quantity of resource units are related to local conditions and to provision rules requiring labour, material, and/or money. Collective-choice arrangements. Most individuals affected by the operational rules can participate in modifying the operational rules [how refreshing. Standing!]. Monitoring. Monitors, who actively audit CPR conditions and appropriator behavior, are accountable to the appropriators or are the appropriators. Graduated sanctions. Appropriators who violate operational rules are likely to be assessed graduated sanctions (depending on the seriousness and context of the offence) by other appropriators, by officials accountable to these appropriators, or by both. Conflict-resolution mechanisms. Appropriators and their officials have rapid access to low-cost local arenas to resolve conflicts among appropriators or between appropriators and officials. Minimal recognition of rights to organize. The rights of appropriators to devise their own institutions are not challenged by external governmental authorities. For CPRs that are parts of larger systems: Nested enterprises. Appropriation, provision, monitoring, enforcement, conflict resolution, and governance activities are organized in multiple layers of nested enterprises.

  • Probably ninety-five percent of our attention goes to numbers, but there's not a lot of power in them.
  • Not that parameters aren't important—they can be, especially in the short term and to the individual who's standing directly in the flow. But they rarely change behavior. If the system is chronically stagnant, parameter changes rarely kick-start it. If it's wildly variable, they don't usually stabilize it. If it's growing out of control, they don't brake it.

  • Numbers become leverage points when they go into ranges that kick off one of the items higher on this list.
  • Probably the most common kind of critical number is the length of delay in a feedback loop.
  • A delay in a feedback process is critical relative to rates of change (growth, fluctuation, decay) in the system state that the feedback loop is trying to control.
  • Delays that are too short cause overreaction, oscillations amplified by the jumpiness of the response. Delays that are too long cause damped, sustained, or exploding oscillations, depending on how much too long. At the extreme they cause chaos. Delays in a system with a threshold, a danger point, a range past which irreversible damage can occur, cause overshoot and collapse.
  • delays are not often easily changeable
  • It's usually easier to slow down the change rate (positive feedback loops, higher on this list), so feedback delays won't cause so much trouble
  • Most systems have evolved or are designed to stay out of sensitive parameter ranges. Mostly, the numbers are not worth the sweat put into them.
  • The plumbing structure, the stocks and flows and their physical arrangement, can have an enormous effect on how a system operates.
