    "Larman's Laws of Organizational Behavior After decades of observation and organizational consulting, here are Larman's Laws of Organizational Behavior. These are observations rather than laws to follow ;) 1. Organizations are implicitly optimized to avoid changing the status quo middle- and first-level manager and "specialist" positions & power structures. 2. As a corollary to (1), any change initiative will be reduced to redefining or overloading the new terminology to mean basically the same as status quo. 3. As a corollary to (1), any change initiative will be derided as "purist", "theoretical", and "needing pragmatic customization for local concerns" -- which deflects from addressing weaknesses and manager/specialist status quo. 4. Culture follows structure. i.e., if you want to really change culture, you have to start with changing structure, because culture does not really change otherwise. and that's why deep systems of thought such as organizational learning are not very sticky or impactful by themselves, and why systems such as scrum (that have a strong focus on structural change at the start) tend to more quickly impact culture. i discovered that john seddon also observed this: "Attempting to change an organization's culture is a folly, it always fails. Peoples' behavior (the culture) is a product of the system; when you change the system peoples' behavior changes." "

Is Design Dead? - 0 views

  • In its common usage, evolutionary design is a disaster. The design ends up being the aggregation of a bunch of ad-hoc tactical decisions, each of which makes the code harder to alter. In many ways you might argue this is no design, certainly it usually leads to a poor design. As Kent puts it, design is there to enable you to keep changing the software easily in the long term. As design deteriorates, so does your ability to make changes effectively. You have the state of software entropy, over time the design gets worse and worse. Not only does this make the software harder to change, it also makes bugs both easier to breed and harder to find and safely kill. This is the "code and fix" nightmare, where the bugs become exponentially more expensive to fix as the project goes on
  • the planned design approach has been around since the 70s, and lots of people have used it. It is better in many ways than code and fix evolutionary design. But it has some faults. The first fault is that it's impossible to think through all the issues that you need to deal with when you are programming. So it's inevitable that when programming you will find things that question the design. However if the designers are done, moved onto another project, what happens? The programmers start coding around the design and entropy sets in. Even if the designer isn't gone, it takes time to sort out the design issues, change the drawings, and then alter the code. There's usually a quicker fix and time pressure. Hence entropy (again).
  • One way to deal with changing requirements is to build flexibility into the design so that you can easily change it as the requirements change. However this requires insight into what kind of changes you expect. A design can be planned to deal with areas of volatility, but while that will help for foreseen requirements changes, it won't help (and can hurt) for unforeseen changes. So you have to understand the requirements well enough to separate the volatile areas, and my observation is that this is very hard. Now some of these requirements problems are due to not understanding requirements clearly enough. So a lot of people focus on requirements engineering processes to get better requirements in the hope that this will prevent the need to change the design later on. But even this direction is one that may not lead to a cure. Many unforeseen requirements changes occur due to changes in the business. Those can't be prevented, however careful your requirements engineering process.

  • The fundamental assumption underlying XP is that it is possible to flatten the change curve enough to make evolutionary design work. This flattening is both enabled by XP and exploited by XP. This is part of the coupling of the XP practices: specifically you can't do those parts of XP that exploit the flattened curve without doing those things that enable the flattening. This is a common source of the controversy over XP. Many people criticize the exploitation without understanding the enabling. Often the criticisms stem from critics' own experience where they didn't do the enabling practices that allow the exploiting practices to work. As a result they got burned and when they see XP they remember the fire.
  • XP's advice is that you not build flexible components and frameworks for the first case that needs that functionality. Let these structures grow as they are needed. If I want a Money class today that handles addition but not multiplication then I build only addition into the Money class. Even if I'm sure I'll need multiplication in the next iteration, and understand how to do it easily, and think it'll be really quick to do, I'll still leave it till that next iteration.
  • You don't want to spend effort adding new capability that won't be needed until a future iteration. And even if the cost is zero, you still don't want to add it because it increases the cost of modification even if it costs nothing to put in. However you can only sensibly behave this way when you are using XP, or a similar technique that lowers the cost of change.
  • My advice to XPers using patterns would be Invest time in learning about patterns Concentrate on when to apply the pattern (not too early) Concentrate on how to implement the pattern in its simplest form first, then add complexity later. If you put a pattern in, and later realize that it isn't pulling its weight - don't be afraid to take it out again.
  • begin by assessing what the likely architecture is. If you see a large amount of data with multiple users, go ahead and use a database from day 1. If you see complex business logic, put in a domain model. However in deference to the gods of YAGNI, when in doubt err on the side of simplicity. Also be ready to simplify your architecture as soon as you see that part of the architecture isn't adding anything.
  • XP design looks for the following skills A constant desire to keep code as clear and simple as possible Refactoring skills so you can confidently make improvements whenever you see the need. A good knowledge of patterns: not just the solutions but also appreciating when to use them and how to evolve into them. Designing with an eye to future changes, knowing that decisions taken now will have to be changed in the future. Knowing how to communicate the design to the people who need to understand it, using code, diagrams and above all: conversation.

James Shore: The Art of Agile Development: Simple Design - 0 views

  • Simple Design AudienceProgrammers Our design is easy to modify and maintain
  • Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. —Antoine de Saint-Exupéry Any intelligent fool can make things bigger, more complex and more violent. It takes a touch of genius and a lot of courage to move in the opposite direction. —Albert Einstein
  • When writing code, agile developers often stop to ask themselves, "What is the simplest thing that could possibly work?" They seem to be obssessed with simplicity. Rather than anticipating changes and providing extensibility hooks and plug-in points, they create a simple design that anticipates as little as possible, as cleanly as possible. Unintuitively, this results in designs that are ready for any change, anticipated or not.
  • ...10 more annotations...
  • I don't think XP and patterns are conflicting. It's how you use patterns. The XP guys have patterns in their toolbox, it's just that they refactor to the patterns once they need the flexibility
  • You Aren't Gonna Need It (YAGNI) This pithy XP saying sums up an important aspect of simple design: avoid speculative coding. Whenever you're tempted to add something to your design, ask yourself if it supports the stories and features you're currently delivering. If not, well... you aren't gonna need it. Your design could change. Your customers' minds could change.
  • We do this because excess code makes change difficult. Speculative design, added to make specific changes easy, often turns out to be wrong in some way, which actually makes changes more difficult. It's usually easier to add to a design than to fix a design that's wrong. The incorrect design has code that depends on it, sometimes locking bad decisions in place.
  • Once and Only Once
  • avoid duplication. "Once and only once" is the Extreme Programming phrase. The authors of The Pragmatic Programmer [Hunt & Thomas] use "don't repeat yourself," or the DRY principle.
  • Self-Documenting Code Simplicity is in the eye of the beholder. It doesn't matter much if you think the design is simple; if the rest of your team or future maintainers of your software find it too complicated, then it is.
  • What if we know we're going to need a feature? Shouldn't we put in a design hook for it? In XP, the plan can change every week. Unless you're implementing the feature that very week, don't put the hook in. The plan could change, leaving you stuck with unneeded code.
  • Results When you create simple designs, you avoid adding support for any features other than the ones you're working on in the current iteration. You finish work more quickly as a result. When you use simple design well, your design supports arbitrary changes easily. Although new features might require a lot of new code, changes to existing code are localized and straightforward.
  • Simple design requires continuous improvement through refactoring and incremental design and architecture. Without it, your design will fail to evolve with your requirements. Don't use simple design as an excuse for poor design. Simplicity requires careful thought. As the Einstein quote at the beginning of this section says, it's a lot easier to create complex designs than simple ones. Don't pretend "simple" means "fastest" or "easiest.
  • Until recently, the accepted best practice in design followed the advice Erich Gamma now disavows: "The key to maximizing reuse lies in anticipating new requirements and changes to existing requirements, and in designing your systems so they can evolve accordingly."

Creating an Agile Culture to Drive Organizational Change - 1 views

agile enterprise adoption culture

shared by Yuval Yeret on 15 May 09 - Cached
  • It is critical that everyone has the same understanding of, and commitment to, the desired outcome: a business that is reliable through predictable technology processes that deliver business agility. To do this, there needs to be a management commitment to develop a focused, on-going practice around the pursuit of organizational maturity. As part of this, gaps in skills and capabilities should be identified and positive action – training, coaching, process improvement and tools deployment – taken in order to close the gap
  • the work force needs to understand the business drivers for Agility. They need to be challenged to improve their quality, improve their cycle times, to improve the frequency of releases and the value they deliver to the customer. They need to know how these things fit within the bigger picture and why improvement is their responsibility.
  • To change a culture it's important to recognize that every knowledge worker makes decisions and takes actions that affect the performance of the business. The culture in the organization is the reflection of those decisions and actions.
  • ...14 more annotations...
  • all the people understand and internalize the concepts and ideals behind the Agile movement
  • translated into concepts that can be widely applied to the many day-to-day decisions each of them will make
  • internalize and live three principles: making progress with imperfect information; existing in a high trust, high social capital culture; and shortening cycle times. These ideas need to be infused into the workforce at every opportunity.
  • it should spread virally. It can start with just one manager, who educates his immediate direct reports on the concepts and then takes the time to reflect and show how each decision is aligned the principles
  • work-in-progress as a liability rather than an asset.
  • Delivering quickly can provide immediate value while delay can result in obviated functionality of little value or missing a more lucrative opportunity while completing existing work-in-progress
  • The Agile Decision Filter
  • . Every member of the team should be educated to understand it, and to be capable of demonstrating how their decisions and actions are concomitant with it. The Decision Filter is
  • Are we making progress with imperfect information? Or are we trying to be perfect before we start? Does this decision add or maintain trust in our organization and with our partners? Or does it remove trust and breed fear? Are we treating work-in-progress as it if were a liability? Or are we treating it like an asset?
  • the team can start to modify their practices one decision at a time and drive towards a goal of business agility
  • The "transition" to Agile will happen slowly, and supporting the change will require training, coaching and tools – but change will be real and long-lasting.
  • By changing your culture using the simple principles captured in The Agile Decision Filter, teams will adopt Agile. Give it a little time and magic will happen. They will voluntarily change their behaviors and adopt Agile practices. They will behave in a fashion aligned with the principles and values behind The Agile Manifesto. They will not resist because they had a say in the changes, which are tailored specifically to their environment and their needs.
  • this approach may seem less prescriptive and straightforward than an "Agile Change Initiative" project plan. And yes, taking on a management-led Agile Transition Initiative looks faster and cheaper,
  • However, it is all wishful thinking, and the only way to get the payoff is to invest the time and show the courage to lead true Agile change. True Agile change requires you to change the culture. To change the culture, teach all your people how to use the Agile Decision Filter and hold them accountable for every decision they make.

tips on reviving retrospectives from the retrospectives yahoo group - 0 views

agile retrospectives agilesparksblog

shared by Yuval Yeret on 08 Jul 09 - No Cached
  • Has the team made changes that make a difference to them as a result of the retrospective?
  • Has the team explored a variety of different topics/areas, or do they stick to pretty much the same agenda around continuous improvement? What is the balance of change/improvement work vs. working on the product?
  • For example, try looking at technical practices, teamwork, or customer relationships... choose what ever seems most relevant to bound the discussion. That might help the team dig deeper and find issues that have more significance for them (now...I'm sure the other changes were significant at the time).
  • ...14 more annotations...
  • Try a 'speed retrospective'. How quickly can the team get together and find one good, solid improvement to make? Make it exciting and use a stopwatch. I wouldn't do this all the time, but again, what harm to try it once?
  • How about one retrospective where you set yourselves the challenge of generating actions from the "What did we do well" column? In other words, find an action designed to magnify an existing positive rather than remedy an existing negative.
  • How about a 'Show and Tell' retrospective where every team member comes to the meeting with an action item and its explanation already prepared? The retrospective would really be each person presenting their idea in turn.
  • How about a retrospective wherein you challenge yourselves to come with a new approach to retrospectives that is so exciting that people would skip other work activities to attend?
  • I find it very important to revisit the outcome of the past retrospective and celebrate the things the team had been able to do differently.
  • The major thing is to make the changes visible and memorizable for everyone and not assuming that people remember what they decided on in the last retro.
  • Another thing is that I would invite team members to take turns in facilitating the retro. So not always the same person runs the retro (this typically also changes the format and techniques a bit).
  • - Heartbeat Retrospective (google for Boris Gloger)
  • - Temperature Reading
  • - Team Radar Chart
  • - Our project / team / product ship - draw a ship on a flip chart, ask the team what moved the ship forward, what blocked it
  • Just to add a totally different direction: I've made good experiences with having a *long* retrospective every few months. The short retrospectives are great to see the trees and optimize the daily work. A two or even three day retrospective helps the team to step back and watch the forrest instead.
  • It is important to get at least one item done every sprint. If you do the retro, but don't implement any of the actions, this is a tremendous demotivator. Better one thing finished that you can celebrate than 5 unfinished things in the queue.
  • Variety is the spice of life, so some variation is essential to keep the freshnees. Change the moderator, do technical focus once, then organisational, then "improving the fun factor", then go back to a general retro.

CIO Perspectives: A Conversation on Agile Transformation, Part 2 - 0 views

agile transformation

shared by Yuval Yeret on 15 May 09 - Cached
  • Part 2
  • The really hard part is around the people transformation - getting developers to work side-by-side with testers and users is a completely foreign concept.
  • The thinking is that IT is mission-critical, so let's not change things without giving it a lot of thought and a lot of consideration
  • ...8 more annotations...
  • The reason there's been so much turnover of CIOs in the last ten years is because the end users – the CEOs, the CFOs and the division heads – are unhappy with the results. When IT professionals realize this, and realize that something like Agile gives them the opportunity to create better value for their businesses, then they're going to be a lot more willing to adopt it. I hope that development organizations are starting to see around that corner.
  • We WANT to go Agile. How do we overcome the skepticism at the CXO level?"
  • My recommendation would be "try it." Agile doesn't equal risk, but changing development methods does equal some risk
  • t can be a big deal to say: "I'm going to change our development methodology." It makes people sit up and want to dive into deep detail before getting on board. The question comes in the form of the old development methodology: "Let me see the high level plan and what the change will be in the deliverables and methodology over the next two years." This is exactly what you're trying to avoid by going to an Agile method.
  • try Agile on a few small projects, measure the results, talk to users about their satisfaction, and then readdress
  • nitiate the shift in the most change-prone areas first, and then work it backwards through the rest of the organization
  • It doesn't happen everywhere at all times, and it doesn't work in all areas. It's good to recognize that up front – that software development projects adapt to this easily, but an infrastructure project would have challenges with this approach. So, select a few areas that would naturally lend themselves to Agile, such as application development, gradually introduce it to these areas that need it most, and then measure results.
  • Again I'd say: "Try it." Agile transition is absolutely about organizational change. To win executive support we need to speak in terms of risk management, measurement and the bottom line.

From the Agile Transformation Trenches: Culture Change with Pigs, not Chickens - 0 views

  • Identify the technical leaders within projects; those that are “self-driven to produce quality results on time … combine technical ability with enough people skills …are trusted and respected by both their managers and fellow developers, are determined to make the team succeed, and usually live the work.” (Chief programmers, Chapter 2:  A Practical Guide to FDD).
  • Sell them the vision: if you cannot sell these people on the benefits to them, their colleagues and the organization of the new way of working then something is wrong
  • Provide in-depth training and on-going coaching. It is better to have a single lead person trained in-depth who can coach his teammates through the basics than to have the whole team trained on the basics with no-one on the team to turn to when the basics are not enough.
  • ...3 more annotations...
  • Providing initial training is simply not enough. When the pressure is on, the temptation to return to previous ways of doing things is often too strong to resist. If technical leads are to work for you, they need on-going support and coaching, and a means by which they can support each other.  Good external coaches (expert chickens?) can help here.
  • Let the technical leads continue working on their projects. Some fail at the final hurdle by doing 1-3 above and then assigning or scheduling the technical leads to coach other projects, effectively turning them from pigs into chickens.
  • To summarize, if you can produce a change in the behavior of the lead pigs, the other pigs will, by definition, follow. However, pigs will not follow chickens for long because chickens are simply not pigs.

    "This presentation was given at the Lean Software and Systems Conference 2012 (LSSC12). Lean/Agile is not just about delivering early and often, it is even more importantly about continuously adapting the way we work towards an improved capability of delivery. Yet how many of us have worked in a continuously improving organization? How many of us have seen one in real life? It's hard to keep management interested in Improvement for very long, making Continuous Improvement a holy grail of sorts. As Lean/Kanban practitioners we believe the only sustainable way to improve is via evolutionary emerging change. But if we the organization is not interested in pursuing it, we have a big problem. Through some challenging situations from real client work we will see a few patterns that fail and a few patterns that show more promise for energizing improvement. We will also look at improvement pace and how to apply kanban approaches to make the improvement more sustainable. We will also explore some local cultural aspects that might affect the drive (or lack of) towards improvement, and how to deal with them, with some interesting insights about the Israeli culture…"
