  * “On the topic of goals, the academic research agrees with your intuition: Having goals improves performance. Spending hours cascading goals up and down the company, however, does not. It takes way too much time and it’s too hard to make sure all the goals line up. We have a market-based approach, where over time our goals all converge, because the top OKRs are known and everyone else’s OKRs are visible.” — Laszlo Bock, Google’s former VP of People Operations

  * "Frederick Taylor’s managerial solutions were unequivocally designed for complicated problems rather than complex ones." – General Stanley McChrystal in "Team of Teams"
  * "Complex systems are fickle and volatile, presenting a broad range of possible outcomes; the type and sheer number of interactions prevent us from making accurate predictions. As a result, treating an ecosystem as though it were a machine with predictable trajectories from input to output is a dangerous folly." – General Stanley McChrystal in "Team of Teams", and related …
  * "The average forecasting error in the U.S. analyst community between 2001 and 2006 was 47 percent over twelve months and 93 percent over twenty-four months. As writer and investor James Montier puts it, 'The evidence on the folly of forecasting is overwhelming . . . frankly the three blind mice have more credibility than any macro-forecaster at seeing what is coming.' In November 2007, economists in the Survey of Professional Forecasters—examining some forty-five thousand economic-data series—foresaw less than a one-in-five-hundred chance of an economic meltdown as severe as the one that would begin one month later." – General Stanley McChrystal in "Team of Teams"
  * "In popular culture, the term “butterfly effect” is almost always misused. It has become synonymous with 'leverage' - the idea of a small thing that has a big impact, with the implication that, like a lever, it can be manipulated to a desired end. This misses the point of Lorenz’s insight. The reality is that small things in a complex system may have no effect or a massive one, and it is virtually impossible to know which will turn out to be the case." – General Stanley McChrystal in "Team of Teams"
  * "Interconnectedness and the ability to transmit information instantly can endow small groups with unprecedented influence: the garage band, the dorm-room start-up, the viral blogger, and the terrorist cell." – General Stanley McChrystal in "Team of Teams"
  * "The pursuit of “efficiency”—getting the most with the least investment of energy, time, or money—was once a laudable goal, but being effective in today’s world is less a question of optimizing for a known (and relatively stable) set of variables than responsiveness to a constantly shifting environment. Adaptability, not efficiency, must become our central competency." – General Stanley McChrystal in "Team of Teams"
  * "We became what we called “a team of teams”: a large command that captured at scale the traits of agility normally limited to small teams." – General Stanley McChrystal in "Team of Teams"
  * "Specifically, we restructured our force from the ground up on principles of extremely transparent information sharing (what we call “shared consciousness”) and decentralized decision-making authority (“empowered execution”)" – General Stanley McChrystal in "Team of Teams"

  * "What had been logical became dumb, and all it took was changing the context." – James Corey in "Abaddon's Gate"
  * Coordinate cross-functionally but work independently - take responsibility. Work with details, but understand the context. Act now—think long-term. Build know-how through continuous learning. Stimulate commitment through involvement. – Scania leadership principles
  * "Lean development is a careful elaboration of a single idea—learn from reality. And learning from reality has the great advantage of enabling you to live in a rational universe." – Allen Ward in "Lean Product and Process Development".

  * "Put key information in the physical environment where it is available at a glance and people are reminded of it in appropriate places." – Allen Ward in "Lean Product and Process Development" on why we seem to want to keep information hidden and pass it through workflows.
  * "Keep in mind that you cannot load the organization to 100% capacity. You need to figure in a buffer, normally in the 15–20% range unless you only do fairly routine development work." – Allen Ward in "Lean Product and Process Development". And related:
      * "Adding a person who is unfamiliar with the project usually slows it down further while they get up to speed. So, lean companies use supervisors as the critical flexible resource. Supervisors are already familiar with each project their sections support. They are experienced developers. They can quickly step in to maintain the momentum and the flow. This critical role of lean supervisors and managers is almost unknown in conventional companies."
  * "The answer is simple: establish a cadence. Start projects at standard intervals, and finish them at standard project lengths, so that the entire development organization is marching to the beat of the same drummer" – Allen Ward in "Lean Product and Process Development".
  * "A plan that is more than one page is much too long to be understood and followed." – Allen Ward in "Lean Product and Process Development".
  * "Conventional project management attempts to answer these questions by defining a detailed plan and trying to stick to it. Instead of learning to surf, conventional organizations try to control the waves! This almost never works." – Allen Ward in "Lean Product and Process Development".
  * "Remain “off-line” from product development. Don’t allow research or advanced development to select a concept for product development. Product Development may use any of the data and ideas created, but research/ advanced development should always start with complete freedom to do whatever makes sense. Research or advanced development concepts are unproven because they have not been produced in volume or used by customers. Development teams must search many concepts to be confident of success." – Allen Ward in "Lean Product and Process Development".
  * "Every specification is a trade-off between what really is wanted and what the state of the art allows. At the beginning of the project, only the old state of the art is known." – Allen Ward in "Lean Product and Process Development".
  * "Your basic negotiating ploy is simple: “Given support A, I can do X. Given support B, I think I can only do Y. X makes 50% more money for the company." – Allen Ward in "Lean Product and Process Development".
  * "You can’t just ask customers what they want and then try to give that to them. By the time you get it built, they’ll want something new." – Steve Jobs
  * "The project leader must be both an entrepreneur and a system designer." – Allen Ward in "Lean Product and Process Development". And related:
      * "In contrast, large conventional companies often make an irrecoverable mistake: They aim project leaders at administering the project rather than designing the system. Whatever the organizational structure, the ESDs (engineering system designers) need to focus the bulk of their time and effort on creating new system knowledge for effective future value streams. It is precisely the ability to formulate a compelling but realistic vision and make good trade-offs that enables profitable products. 'Product visions' are just hot air unless they are inspired by engineering imagination and infused with engineering judgment."
      * "Why doesn’t every company use ESDs effectively? Because ESDs drive bureaucrats nuts, for two main reasons: 1. ESDs trust their own judgment and love their own vision, and when these get off track, they can be disastrous. 2. ESDs won’t play the game; good bureaucrats do. Bureaucrats are properly deferential to authority. They mingle well at parties."
  * "Committees never do anything completely wrong, but they never do anything brilliant either." – Kelly Johnson
  * "We should buy both design and make whenever we can. Why? Because it reduces the amount that we have to learn." – Allen Ward in "Lean Product and Process Development".
  * "As a pilot instructor would say, 'Relax and level the wings.' In other words, stop doing those things that make the situation worse and take measured corrective action; which is, in this case, value-stream alignment." – Allen Ward in "Lean Product and Process Development".
  * "Quality, timing, and design integration are strongly interactive properties, not isolated ones. Interactive properties have more effect on profit than isolated ones." – Allen Ward in "Lean Product and Process Development". And related:
      * "A good system designer will rarely choose the supplier with the lowest price, even if cost is important to the product. Price is an isolated property of the part. It has little effect on how the part works in the system as a whole. Suppose a part involves 10% of the cost of the product—increasing the part cost by 10% will increase the product cost by only 1%. The effect is isolated. Conversely, if the part fails in service, the whole product fails. If the supplier delivers the part late, the whole product is late. If the part design doesn’t fit well into the system design, the customer is likely to be dissatisfied with the whole system."
  * "In summary, these wastes are: 1. Scatter: management actions such as reorganization and workload variation that make knowledge hard to get to the right place; barriers to communication, such as the use of multiple forms (paper or electronic) to carry information through channels; and poor tools, which most often generate information that would have been useful in preventing a past problem but do not prevent future problems efficiently. 2. Hand-off: the most critical waste, occurring whenever a company separates responsibility, knowledge, action, and feedback; useless information, usually generated to provide management with the illusion of control; and waiting, the practice of putting learning into batches so that knowledge flows in only one direction. 3. Wishful Thinking: making decisions without data; testing to specifications, which leaves the product vulnerable to problems too infrequent for the specifications to catch; and discarded knowledge, which is the failure to put everything learned during a project into usable form." – Allen Ward in "Lean Product and Process Development".
  * "Testing’s job is to break the product, record how it breaks, and advise design engineering on how to make it harder to break." – Allen Ward in "Lean Product and Process Development".
  * "The natural intuition is that looking at one alternative is cheaper, easier, and faster than looking at multiple alternatives. This intuition is usually wrong, because looking at a lot of alternatives early is usually cheaper than looking at a few alternatives later; and choosing the one alternative, if we must do it with little knowledge, is simply wishful thinking." – Allen Ward in "Lean Product and Process Development".
  * "My job is to keep people from making decisions too quickly." – Senior manager at Toyota
  * "It’s hard to find a development upstream process that has to finish before a downstream process can start. This is a major difference between development and manufacturing, and between development and construction (the environment for which PERT was designed)." – Allen Ward in "Lean Product and Process Development". And related:
      * "Sequencing creates a batch process in which all the decisions and learning of a particular kind happen at once. This: 1) Slows the process because people wait longer than they need to before starting. 2) Creates one-way rather than multiway information flows; the upstream processes don’t get enough input from the downstream processes. 3) Gives the upstream developers more power than the downstream, creating quality problems. 4) Causes large variations in workload, which in turn causes scatter waste."
  * "What is the most fundamental waste in conventional companies? Hand-off … A hand-off occurs whenever we separate knowledge, responsibility, action, and feedback. Hand-off is a disaster because it results in decisions being made by people who do not have enough knowledge to make them well or the opportunity to make them happen. Similar to the waste of overproduction on the plant floor, hand-off tends to produce many other kinds of development waste" – Allen Ward in "Lean Product and Process Development".
  * "Hand-off creates finger-pointing—the conventional management salute."  – Allen Ward in "Lean Product and Process Development".
  * "The most important wastes in development are wastes of knowledge." – Allen Ward in "Lean Product and Process Development".
  * "There are three primary categories of knowledge wastes: scatter, hand-off, and wishful thinking" – Allen Ward in "Lean Product and Process Development".
  * "Scatter often is a death spiral, a feedback loop that makes things worse and worse. As things “fall through the cracks” because of disorganization, developers spend more time “fighting fires,” responding to demands for information by others, and looking for information and harassing other developers to try to get action. Everything becomes a crisis" – Allen Ward in "Lean Product and Process Development".
  * "These responses to scatter create more scatter. The result: more time spent creating waste and less time creating value." – Allen Ward in "Lean Product and Process Development".
  * "Going faster improves profitability in several ways: 1) Saving time saves money. The size of a team is determined mostly by the range of expertise required. Getting done faster frees resources. 2) In markets with low switching costs for the customer to change from one supplier to another, going faster means you get your share of the market sooner. You probably keep it just as long, so you add some months or years of profit to your ROI. 3) In markets with high switching costs, getting to market first could mean you get most of the market—and you get to keep it. 4) If you are selling to industrial customers that are in a hurry themselves, the promise of speed may be enough by itself to radically improve market share and ROI. 5) Above all, of course, going faster means learning faster. If you learn 20% faster than your competitors, 30 projects later you will be 60% ahead—a tremendous advantage." – Allen Ward in "Lean Product and Process Development"
  * "Estimate value-creating time for developers. Ask your developers (anonymously, at least at first) what fraction of their time is spent creating value—creating usable new knowledge or manufacturing hardware. Calculate how much you could increase your throughput by increasing your fraction of value-adding creating time. Publicize." – Allen Ward in "Lean Product and Process Development"
  * "Almost all defective projects result from not having the right knowledge in the right place at the right time. Therefore, usable knowledge is the basic value created during development. Usable development knowledge prevents defects, excites customers, and creates profitable operational value streams." – Allen Ward in "Lean Product and Process Development".
  * "Usable knowledge is created by three basic kinds of learning: 1. Integration learning includes learning about customers, suppliers, partners, the physical environment in which the product will be used, etc. It helps us understand how to integrate our designs with the needs of others—most importantly, our customers. 2. Innovation learning creates new possible solutions. 3. Feasibility learning enables better decisions among the possible new solutions, avoiding cost and quality problems, or project overruns." – Allen Ward in "Lean Product and Process Development".
  * "Keep the ROI model simple enough for developers to understand and use in daily work." – Allen Ward in "Lean Product and Process Development"
  * "Improving the system to prevent defects does NOT mean adding more tests, analysis, signatures, gates, or controls to the system. These things make developers work harder, in an effort to prevent a particular problem from reoccurring. But the basic problem is that every developer I know already is working too hard, so things “fall through the cracks.” Improving the system means making things easier for developers, not harder." – Allen Ward in "Lean Product and Process Development"
  * "Use project defect rate to spur change Determine your project defect rate. To do this, plot the distribution of ROIs for recent projects, color coding for defective and completely successful projects. Compute how much more money you would make if all projects returned the maximum ROI. Publicize this in internal media, or post it in halls; use it to agitate for lean development." – Allen Ward in "Lean Product and Process Development".

  * "This is one purpose of the Scrum Product Backlog. It acts as a tool for leveling or smoothing the introduction of work to feature teams. A small buffer of high-quality inventory created to support level pull is another example of useful temporarily necessary waste" – Craig Larman, Bas Vodde from "Scaling Lean and Agile Development"

  * "Complex systems exhibit several kinds of telltale behaviour. I will describe some of these behaviours briefly here; they will be examined in more detail in later chapters. • self-organization into patterns, as occurs with flocks of birds or schools of fish • chaotic behaviour where small changes in initial conditions (‘the flapping of a butterfly’s wings in Argentina’) produce large later changes (‘a hurricane in the Caribbean’) • ‘fat-tailed’ behaviour, where rare events (e.g. mass extinctions and market crashes) occur much more often than would be predicted by a normal (bell-curve) distribution • adaptive interaction, where interacting agents (as in markets or the Prisoner’s Dilemma) modify their strategies in diverse ways as experience accumulates. In addition, as already mentioned, emergent behaviour is an essential requirement for calling a system ‘complex’." – John Holland from "A Very Short Introduction to Complexity"

  * "While working with these teams, I discovered that they were all making the same fundamental errors and they were perpetually repeating those errors … In every group I worked with, I found the project leads were spending nearly all their time writing code and almost none of their time thinking about the project. The leads didn't spend time trying to keep schedules on track, they didn't look for foreseeable problems so they could circumvent them, they didn't work to protect other team members from unnecessary work, they didn't pay particular attention to training other team members, they didn't set detailed project goals or create effective attack plans. The leads were spending too much time working when they should have been thinking." – in preface by Steve Maguire "Debugging the Development Process".

  * "I could list all of the qualities that I notice in clean code, but there is one overarching quality that leads to all of them. Clean code always looks like it was written by someone who cares. There is nothing obvious that you can do to make it better. All of those things were thought about by the code’s author, and if you try to imagine improvements, you’re led back to where you are, sitting in appreciation of the code someone left for you—code left by someone who cares deeply about the craft." – Michael Feathers
  * "You know you are working on clean code when each routine you read turns out to be pretty much what you expected. You can call it beautiful code when the code also makes it look like the language was made for the problem." Ward Cunningham

Everyone knows the result on that day. The object of building a project model is to divide the project into component pieces, each of which has this same characteristic: Each activity must be defined by a deliverable with objective completion criteria.

  * "The task is then to refine the code base to better meet customer need. If that is not clear, the programmers should not write a line of code. Every line of code costs money to write and more money to support. It is better for developers to be surfing than writing code that won't be needed. If they write code that ultimately is not used, I will be paying for that code for the life of the system, which is typically longer than my professional life. If they went surfing, they would have fun, and I would have a less expensive system and fewer headaches to maintain." – Jeff Sutherland, quoted from object–technology@yahoogroups.com Message 121
  * "Predictable outcomes are one of the key expectations that the marketplace imposes on companies … Unfortunately, software development has a notorious reputation for being unpredictable, so there is great pressure to make it more predictable.

  * "Of the organizations that are attempting to implement Scrum, probably 30–35% will successfully implement it. And that's because of this core problem. Most organizations don't want to be faced with what they don't want to see. And this puts it up there and says 'are you going to do something about it, or not'?" – Scrum et al by Ken Schwaber talking at Google.
