Agile Manifesto Signatories

Manifesto for Agile Software Development

“We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
* Individuals and interactions over processes and tools.
* Working software over comprehensive documentation.
* Customer collaboration over contract negotiation.
* Responding to change over following a plan.
That is, while there is value in the items on the right, we value the items on the left more.”

Time for Equilibrium

“Misfit provides an incentive to change; good fit provides none. In theory the process is eventually bound to reach the equilibrium of well-fitting forms. However, for the fit to occur in practice, one vital condition must be satisfied. It must have time to happen. The process must be able to achieve equilibrium before the next culture change upsets it again... The direct response is the feedback of the process. If the process is to maintain the good fit ... while the culture drifts, it needs a feedback sensitive enough to take action the moment that one of the potential failures actually occurs.”

Rapid Change

“At the same time that problems increase in quantity, complexity, and difficulty, they also change faster than before.”

Aristotle

Four Causes

“Plainly, then, these are the causes, and this is how many they are. They are four, and the student of nature should know them all, and it will be his method, when stating on account of what, to get back to them all: the matter, the form, the thing which effects the change, and what the thing is for.”'

People Characteristics

"People, as active devices, have success modes and failure modes. The following are the main ones that I have named and used to date:
1. People are communicating beings, doing best face-to-face, in person, with real-time question and answer.
2. People have trouble acting consistently over time.
3. People are highly variable, varying from day to day and place to place.
4. People generally want to be good citizens, are good at looking around, taking initiative, and doing 'whatever is needed' to get the project to work.
There are other characteristics that I won’t expand here:
- People need both think time and communicating opportunities...
- People work well from examples...
- People prefer to fail conservatively than to risk succeeding differently; prefer to invent than to research, can only keep a small amount in their heads, and do make mistakes, and find it hard to change their habits.
- Individual personalities easily dominate a project.
- A person’s personality profile strongly affects their ability to perform specific assignments."

Cheeseburgers

"Development is inherently different from production. But managers of development and allied efforts often allow their thinking to be shaped by a management philosophy derived entirely from a production environment.
Imagine for the moment that you’re the manager of the local fast food franchise. It makes perfect sense for you to take any or all of the following efficient production measures:
- Squeeze out error. Make the machine (the human machine) run as smoothly as possible.
- Take a hard line about people goofing off on the job.
- Treat workers as interchangeable pieces of the machine.
- Optimize the steady state. (Don’t even think about how the operation got up to speed, or what it would take to close it down.)
- Standardize procedure. Do everything by the book.
- Eliminate experimentation—that’s what the folks at headquarters are paid for.
These would be reasonable approaches if you were in the fast food business (or any production environment), but you’re not. The 'make a cheeseburger, sell a cheeseburger' mentality can be fatal in your development area. It can only serve to damp your people’s spirits and focus their attention away from the real problems at hand. This style of management will be directly at odds with the work.
To manage thinking workers effectively, you need to take measures nearly opposite those listed above."

Error Quota

"For most thinking workers, making an occasional mistake is a natural and healthy part of their work. But there can be an almost Biblical association between error on the job and sin. This is an attitude we need to take specific pains to change. Speaking to a group of software managers, we introduced a strategy for what we think of as iterative design. The idea is that some designs are intrinsically defect-prone; they ought to be rejected, not repaired. Such dead ends should be expected in the design activity. The lost effort of the dead end is a small price to pay for a clean, fresh start. To our surprise, many managers felt this would pose an impossible political problem for their own bosses: 'How can we throw away a product that our company has paid to produce?' They seemed to believe that they’d be better off salvaging the defective version even though it might cost more in the long run. Fostering an atmosphere that doesn’t allow for error simply makes people defensive. They don’t try things that may turn out badly. You encourage this defensiveness when you try to systematize the process, when you impose rigid methodologies so that staff members are not allowed to make any of the key strategic decisions lest they make them incorrectly. The average level of technology may be modestly improved by any steps you take to inhibit error. The team sociology, however, can suffer grievously. The opposite approach would be to encourage people to make some errors. You do this by asking your folks on occasion what dead-end roads they’ve been down, and by making sure they understand that 'none' is not the best answer. When people blow it, they should be congratulated — that’s part of what they’re being paid for."

Change as Order

“We no longer even understand the question whether change is by itself good or bad, ... We start out with the axiom that it is the norm. We do not see change as altering the order... We see change as being order itself - indeed the only order we can comprehend today is a dynamic, a moving, a changing one.”

Big University Relics

“Thirty years from now the big university campuses will be relics. Universities won't survive. It's as large a change as when we first got the printed book. Do you realize that the cost of higher education has risen as fast as the cost of health care? And for the middle-class family, college education for their children is as much of a necessity as is medical care — without it the kids have no future. Such totally uncontrollable expenditures, without any visible improvement in either the content or the quality of education, means that the system is rapidly becoming untenable. Higher education is in deep crisis.”

Cargo Cult

“...there have been many experiments running rats through all kinds of mazes, and so on — with little clear result. But in 1937 a man named Young did a very interesting one. He had a long corridor with doors all along one side where the rats came in, and doors along the other side where the food was. He wanted to see if he could train rats to go to the third door down from wherever he started them off. No. The rats went immediately to the door where the food had been the time before. The question was, how did the rats know, because the corridor was so beautifully built and so uniform, that this was the same door as before? Obviously there was something about the door that was different from the other doors. So he painted the doors very carefully, arranging the textures on the faces of the doors exactly the same. Still the rats could tell. Then he thought maybe they were smelling the food, so he used chemicals to change the smell after each run. Still the rats could tell. Then he realized the rats might be able to tell by seeing the lights and the arrangement in the laboratory like any commonsense person. So he covered the corridor, and still the rats could tell. He finally found that they could tell by the way the floor sounded when they ran over it. And he could only fix that by putting his corridor in sand. So he covered one after another of all possible clues and finally was able to fool the rats so that they had to learn to go to the third door. If he relaxed any of his conditions, the rats could tell. Now, from a scientific standpoint, that is an A-number-one experiment. That is the experiment that makes rat-running experiments sensible, because it uncovers the clues that the rat is really using — not what you think it's using. And that is the experiment that tells exactly what conditions you have to use in order to be careful and control everything in an experiment with rat-running. I looked into the subsequent history of this research. The next experiment, and the one after that, never referred to Mr. Young. They never used any of his criteria of putting the corridor on sand, or of being very careful. They just went right on running rats in the same old way, and paid no attention to the great discoveries of Mr. Young, and his papers are not referred to, because he didn't discover anything about rats. In fact, he discovered all the things you have to do to discover something about rats. But not paying attention to experiments like that is a characteristic of cargo cult science.”

Slow Progress

“From the earliest times of which we have record — back, say, to two thousand years before Christ [BCE 2000] down to the beginning of the eighteenth century [CE 1700] — there was no very great change in the standard of life of the average man living in the civilised centres of the earth... This slow rate of progress, or lack of progress, was due to two reasons — to the remarkable absence of important technical improvements and to the failure of capital to accumulate.”

Technological Unemployment

“In our own lifetimes... we may be able to perform all the operations of agriculture, mining, and manufacture with a quarter of the human effort to which we have been accustomed. For the moment the very rapidity of these changes is hurting us and bringing difficult problems to solve... We are being afflicted with... technological unemployment. This means unemployment due to our discovery of means of economising the use of labour outrunning the pace at which we can find new uses for labour. But this is only a temporary phase of maladjustment... In the long run... mankind is solving its economic problem. I would predict that the standard of life in progressive countries one hundred years hence will be between four and eight times as high as it is today.”

Materialist Science

“In materialist science, only that is true that you can objectify, what you can measure, what you can duplicate, or what you can falsify. Then it is true. Now what you feel and what you think, your consciousness, you cannot objectify, you cannot duplicate, you cannot measure, and you cannot falsify. Consciousness, the essence of who you are, what you feel, what you think, is beyond our current materialist science. So, they call it an illusion. But it is the essence of who we are. We have to expand science into post-materialist science. We have to change the paradigm to include subjective experiences... Science should include subjective experiences into the scientific method... The materialist aspect of science is still important, but it's not enough... This is a totally different approach when you realize that everything has its subjective aspects.”

Efficiency and Variation

“Corporations, in the name of efficiency, suppress variation by 'getting all the ducks in line'. To optimize productivity, they evolve highly refined and internally consistent operating systems. Payoff results - as long as the music lasts. But in the face of nontraditional competitors or major environmental discontinuities, all that streamlining and reengineering limits diversity, suppresses self-organization by those closest to the disruptive change, and curtails a bottom-up emergent response to cope more effectively... Nothing fails like success. Over-adaptive organizations become inflexible. Disruptive change leaves them as helpless as a beached whale.”

Specifications

“It is easier to change the specification to fit the program than vice versa.”

Balance Efficiency and Generality

“Our progress, then, is measured by the balance we achieve between efficiency and generality. As the nature of our involvement with computation changes — and it does — the appropriate description of language changes; our emphasis shifts. I feel that our successor model will show such a change. Computer science is a restless infant and its progress depends as much on shifts in point of view as on the orderly development of our current concepts.”

Computational Mind Probabilistic

“The computational theory thus embraces an alternative kind of computer with many elements that are active to a degree corresponding to the probability that some statement is true or false, and in which the activity levels change smoothly to register new and roughly accurate probabilities. (As we shall see, that may be the way the brain works.) The key idea is that the answer to the question 'What makes a system smart?' is not the kind of stuff it is made of or the kind of energy flowing through it, but what the parts of the machine stand for and how the patterns of changes inside it are designed to mirror truth-preserving relationships (including probabilistic and fuzzy truths).”

Irresponsible Dreams

“The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there. In most other fields of human endeavour there is change, but rarely progress ... And in most fields we do not even know how to evaluate change.”

Changing Opinion

“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again.

I cannot recall the last time something like that happened in politics or religion.”

Herbert_Simon

Design and Analysis

“In view of the key role of design in professional activity, it is ironic that in this century the natural sciences almost drove the sciences of the artificial from professional school curricula, a development that peaked about two or three decades after the Second World War. Engineering schools gradually became schools of physics and mathematics; medical schools became schools of biological science; business schools became schools of finite mathematics. The use of adjectives like 'applied' concealed, but did not change, the fact. It simply meant that in the professional schools those topics were selected from mathematics and the natural sciences for emphasis which were thought to be most nearly relevant to professional practice. It did not mean that design continued to be taught, as distinguished from analysis.”

Faster Horse

“However, even if Ford didn’t verbalize his thoughts on customers’ ostensible inability to communicate their unmet needs for innovative products — history indicates that Henry Ford most certainly did think along those lines... Henry Ford froze the design of the Model T... Ford had no compelling reason to innovate in any other sphere other than cost and price reduction... But everything changed with the onset of the innovations introduced by General Motors in the 1920s, which took the direct opposite of Henry Ford’s tack of “Any color … so long as it is black” and is best summed up by Alfred Sloan’s consumer-research driven “A Car for Every Purse and Purpose”... In 1921, the Ford Motor Company sold about 2/3 of all the cars built in the U.S. By 1926, this share had fallen to approximately 1/3. And in 1927, when Ford belatedly responded (at tremendous financial cost and internal strife) to changes in the market’s tastes and competitive innovation by shutting down production temporarily to re-tool his factories and bring the Model A to the market, that percentage fell to about 15%... Yes, some customers in certain types of businesses are quite capable of verbalizing precisely what sort of innovative product one could build and sell them. And of course, customers in other types of businesses are wholly incapable of verbalizing, with any sort of fidelity whatsoever, what they need and why they need it. An innovator should have understanding of one’s customers and their problems via empirical, observational, anecdotal methods or even intuition. They should also feel free to ignore customers’ inputs. Because by now it should be clear that Ford’s adherence to his vision of the mass-market car and how to materialize that vision was instrumental in both his early success in growing Ford Motor Company as well as his later failure to respond in a timely and effective manner to rapid innovation in the marketplace.”'

In our modern age, laboratories turn out an alloy a day, or more, with properties made to order. The alloying of metals led to the rise and fall of civilizations, but the changes were too slow to be appreciated. A truer blade meant victory over the invaders, but changes were local and slow enough to be absorbed by a million tiny adjustments without destroying the species. With an alloy a day, we can no longer be sure. Science and engineering have been the catalysts for the unprecedented speed and magnitude of change. The physicist shows us how to harness the power of the nucleus; the chemist shows us how to increase the quantity of our food; the geneticist shows us how to improve the quality of our children. But science and engineering have been unable to keep pace with the second-order effects produced by their first-order victories. The excess heat from the nuclear generator alters the spawning pattern of fish, and, before adjustments can be made, other species have produced irreversible changes in the ecology of the river and its borders. The pesticide eliminates one insect only to the advantage of others that may be worse, or the herbicide clears the rain forest for farming, but the resulting soil changes make the land less productive than it was before. And of what we are doing to our progeny, we still have only ghastly hints. Some have said the general systems movement was born out of the failures of science, but it would be more accurate to say the general systems approach is needed because science has been such a success. Science and technology have colonized the planet, and nothing in our lives is untouched. In this changing, they have revealed a complexity with which they are not prepared to deal. The general systems movement has taken up the task of helping scientists unravel complexity, technologists to master it, and others to learn to live with it.”

Vending Machines

“When the vending machines had been in the common room, a large crowd always hovered around them — but not particularly for fol-de-rol, as the manager had so quickly assumed... Informal mechanisms always exist and it is dangerous to change things without understanding them.”

Management Deskilling

“Even though the nth-level manager may have originally been a programmer, which is rare enough, he has almost certainly lost any programming ability by the time he reaches these heights. Given the rapid change of programming techniques and hardware, the higher-level manager becomes obsolete even if he retains the skills he originally had and keeps them sharply honed, for those languages and those machines are no longer in use. In a small survey of working programmers, only 15 percent of the first-line managers were thought to be as skillful as the programmers themselves, and none of the higher-level managers.”

Biological Evolution Outrun By Cultural Change

“Because it is... far slower than Lamarckian evolution, biological evolution is always quickly outrun by cultural change.”

Knowledge is the Ultimate Emancipator

“Pure knowledge is the ultimate emancipator. It equalizes people and sovereign states, erodes the archaic barriers of superstition and promises to lift the trajectory of cultural evolution. But I do not believe that it can change the ground rules of human behavior or alter the main course of history's predictable trajectory.”

Time

“Time is the inexorable progress of computation. If we think about things in the world as being governed by rules, then what happens in the course of time is those rules get applied... The thing that changes through time is that we've applied these rules more and more and more times.”

Paradigm Change

“When you change the paradigm, lots of stuff can come out. In science, the biggest paradigm change that's already happened... which is model things in nature with programs not with equations. For 300 years there was this tradition that [if] you want to make a model in science that's an exact model, write down a mathematical equation. People don't do that anymore in most areas of science... It's fun to see this transition from what seems impossible to what becomes obvious.”

Technology Leadership

“The questions that we face today are finally about leadership. Will there be leaders who are able to recognize the historical moment and the choices it presents? Will they find ways to create the organizational conditions in which new visions, new concepts, and a new language of workplace relations can emerge? Will they be able to create organizational innovations that can exploit the unique capacities of the new technology and thus mobilize their organization's productive potential to meet the heightened rigors of global competition? Will there be leaders who understand the crucial role that human beings from each organizational stratum can play in adding value to the production of goods and services? If not, we will be stranded in a new world with old solutions. We will suffer through the unintended consequences of change, because we have failed to understand this technology and how it differs from what came before.”

Share the Fruits

“Taylor believed it was necessary to share the fruits of such productivity increases and saw the differential piece-rate system, a central tenet of scientific management, as a method of uniting workers and managers in a bond of common interest. But incentive wages are devilishly hard to administer, and all too often, managers attracted to differential wage schemes succumbed to shortcuts that promised fast gains. Managers would frequently change piece rates as workers learned to meet the standards. This led to the complaints of overwork with which unions relentlessly dogged proponents of Taylorism. Scientific management frequently meant not only that individual effort was simplified (either because of labor-saving equipment or new organizational methods that fragmented tasks into their simplest components), but also that the pace of effort was intensified, thus raising the level of fatigue and stress.”

Technological Innovations

“History reveals the power of certain technological innovations to transform the mental life of an era -- the feelings, sensibilities, perceptions, expectations, assumptions, and, above all, possibilities that define a community. From the social influence of the medieval castle,' to the coming of the printed book, to the social and physical upheaval associated with the rise of the automobile -- each specific example serves to drive home a similar message. An important technological innovation is not usefully thought of as a unitary cause eliciting a series of discrete effects. Instead, it can be seen as an alteration of the material horizon of our world, with transformative implications for both the contours and the interior texture of our lives. Technology makes the world a new place...”

Technology Change

“To fully grasp the way in which a major new technology can change the world... it is necessary to consider both the manner in which it creates intrinsically new qualities of experience and the way in which new possibilities are engaged by the often-conflicting demands of social, political, and economic interests in order to produce a 'choice.' To concentrate only on intrinsic change and the texture of an emergent mentality is to ignore the real weight of history and the diversity of interests that pervade collective behavior. However, to narrow all discussion of technological change to the play of these interests overlooks the essential power of technology to reorder the rules of the game and thus our experience as players. Moreover, these two dimensions of technological change, the intrinsic and the contingent, need to be understood, not separately, but in relation to one another. The same innovation that abstracts work and increases its intellectual content, thus enhancing the learning of lower level employees... can also, within the context of the choices by which it is adapted, be experienced as a new source of divisiveness and control.”
