 * '''Dale Emery''': "So once again a pattern emerges: Someone really smart says something clearly nonsensical. I think, “That makes no sense,” and let it go. Then someone else really smart says something similar. I think, “How the hell does that work?” Eventually, when enough really smart people have said the same stupid thing, I think, “That makes no sense. I’d better try it.” Then I try it, and it makes sense. Immediately thereafter I wonder why it isn’t obvious to everyone." (http://cwd.dhemery.com/2011/01/ribcage/)

Herd D reports 24 head. Herd E reports 546 elephant sounds per day. Herd F reports elephant skin rgb values of (192, 192, 192).  Herd G reports an average height of 11 ft. So, there are 50,000 + 84 + 92,000 + 24 + 546 + 192 + 11 = 142,857 Elephant Points in the veldt. The average herd has 20,408.142857143 Elephant Points.

Yep; sometimes it does happen:  The coders get so confused that we end up with useless complexity that does ''NOTHING BUT'' introduce bug(s).  I've found that it doesn't happen very often, but I find it entertaining when I see one." (''XP@yahoogroups'', 8/8/2008)

 * '''Steve Freeman''': "I've seen too many instances of groups that go 'Agile' (31 Flavours) without considering that this requires technical skills as well as index cards and donuts. If an organisation adopting Agile still treats design and coding as a junior stepping stone to more important jobs, then they are likely to see the 'Third-Iteration Crash' and prove the critics right."

 * '''Esther Derby''': "Teams need time to develop the social glue that enables high performance. They understand each other's strengths and weaknesses, develop shared knowledge, and discover how to learn together.  When new people are constantly arriving and leaving, a group may never develop the shared approaches and shared knowledge that permit teams to outperform a group of individuals."

 * '''Kent Beck''': "If the team shares a goal, they find ways to help each other. If they don't share a goal, they might just do any old thing (or play solitaire). So, to my mind, finding ways to help the team share goals is more powerful than careful task assignment or maximizing utilization." (''extremeprogramming@yahoogroups'' 2/29/2008)

 * '''Alan Shalloway''': "TDD is not up-front testing, but using tests to analyze and design code.  It forces you to ask - what is required of this method or module?  How can I verify that?  What interface is needed?  These are all analysis and design issues." (posted on ''leanagilescrum@yahoogroups'' 2/14/2008)

 * '''Voltaire''': "Doubt is uncomfortable, certainty is ridiculous."

 * '''Ron Jeffries''': "Software development is thinking work. It is unwise to imagine that we, no matter how smart we are, can do the thinking for a whole team, all day, every day. We need them to think for themselves. Therefore we need to behave in whatever ways are most helpful to them doing that."

 * '''Ron Jeffries''': "Just saying 'do this' ... no. I've done a lot of that and it was always wasteful." (posted on ''leanagilescrum@yahoogroups'' 1/30/2008)

 * '''Bob Sutton''': "Saying smart things and giving smart answers are important. Learning to listen to others and to ask smart questions is more important."

 * '''Nancy Van Schooenderwoert''': "Defect rate is key for agile teams and I see a lot of Scrum implementations that have not paid enough attention to the agile technical practices (from XP) and so they struggle along spending significant time on bug-related activity, which makes it hard to complete the stories they've taken into their sprint." (posted on ''extremeprogramming@yahoogroups'', 1/27/2008)

 * '''Peter Alfvin''': "Ironically, despite Scrum's focus on empirical process control, I think one of it's greatest strengths is that it's simple, prescriptive and well documented.  It can be used 'off the shelf' and followed 'by the book' by relatively immature organizations to get the lean benefits of improved flow and continuous improvement and avoid some common management dysfunctions.  As such, it's a nice stepping stone for organizations trying to start out with lean and agile." (posted on ''leanagilescrum@yahoogroups'')

 * '''The Wizard of Oz''': "Back where I come from, we have universities, seats of great learning, where men go to become great thinkers. And when they come out, they think deep thoughts and with no more brains than you have. But they have one thing you haven't got: a diploma. Therefore. I hereby confer upon you the honorary degree of Th. D...that's Doctor of Thinkology."  (Mary Poppendieck's take on certification, posted on ''leandevelopment@yahoogroups'')

 * '''Paul Oldfield''': "At the time of estimating, we don't know what we don't know; we have to do 1 of 2 things... Estimate or Investigate." (on ''scrumdevelopment@yahoogroups'')

 * '''M.A. Jackson''': "The beginning of wisdom for a software engineer is to recognize the difference between getting a program to work, and getting it right. A program which does not work is undoubtedly wrong; but a program which does work is not necessarily right. It may still be wrong because it is hard to understand; or because it is hard to maintain as program requirements change; or because its structure is different from the structure of the problem; or because we cannot be sure that it does indeed work." (''Principles of Program Design'', ISBN:0123790506)

 * '''Ogunnaike and Ray''': "It is typical to adopt the defined (theoretical) modeling approach when the underlying mechanisms by which a process operates are reasonably well understood.  When the process is too complicated for the defined approach, the empirical approach is the appropriate choice." (''Process Dynamics, Modeling, and Control'' ISBN:0195091191)

 * '''Don Gray''': "I recently told a potential client the effort was bigger than a bread box but smaller than a semi-tractor-trailer." (on ''scrumdevelopment@yahoogroups'')

 * '''Ilja Preuss''': "Minimizing rework is work, too (for example, up front design). If taken to the extremes, it's very likely to be more work than the prevented rework.  So what you will want to do is not minimizing rework, but finding a good balance.  In my experience, the best rule of thumb is to prevent rework by not doing work that isn't yet absolutely needed to be done. Having to rework something because I've committed to it too early is one of the most costly things that can happen. Keeping my options open as long as possible, until I have as much information as possible, is the more effective strategy." (on ''agileprojectmanagement@yahoogroups'')

 * '''Ilja Preuss''': "I can empathize with getting frustrated. Unfortunately I've found that it doesn't make me more effective. In fact I find that I am better at communicating and motivating when I'm rather emotionally detached from the results I'm getting.  So now the best I can do when I get frustrated is to backtrack and talk to someone who isn't involved. Only when I'm no longer frustrated am I in a position to effectively coach/lead/influence the team again." (on ''scrumdevelopment@yahoogroups'')

 * '''William Pietri''': "There's no rule against planning ahead in an agile process.  There is a rule against stopping other work to plan. And it's also poor form to decline to update your plan in the face of new information, or to decide you've done such a good job planning that you don't need to frequently test your theories in the real world." (on ''agile-usability@yahoogroups'')

 * '''Liu Shao-ch'i''': "There is no such thing as a perfect leader either in the past or present, in China or elsewhere. If there is one, he is only pretending, like a pig inserting scallions into its nose in an effort to look like an elephant."

 * '''Dave Barrett''': "Lock a single programmer away in a closet for a month and I guarantee you he will underperform.  Make him have to stand up and tell his teammates how much work he's done each day, and he'll do a bit better.  Give him someone to bounce ideas off, and he will do even better.  Give him someone to ask for help when he's stuck, and his performance will improve even more.  Give him a way to share in the sucesses of those around him and it will improve some more.  And so on...." (on ''scrumdevelopment@yahoogroups'')

 * '''unnamed business analyst''': "[The business customers] respond to questions really quickly, ''sometimes on the same day''."

Most people will choose the familiar, even though uncomfortable, over the unfamiliar, because of that power." (from ''The New Peoplemaking'' ISBN:0831400706, pp. 144-145)

 * '''Jerry Weinberg''': "Even software that is initially well designed and implemented begins to deteriorate and lose its maintainability in a software culture that doesn't regularly invest in maintainability." (from ''Quality Software Management: Vol. 1, Systems Thinking'' ISBN:0932633226)

 * '''Taiichi Ohno''': "Something is wrong if workers do not look around each day, find things that are tedious or boring, and then rewrite the procedures. Even last month’s manual should be out of date."

 * '''Yoshio Shima''', Director, Toyoda Machine Works: "If you believe that standards are writ in stone, you will fail.  You have to believe that standards are there to be changed."

 * '''Peter Senge''': "When you ask people about what it is like being part of a great team, what is most striking is the meaningfulness of the experience. People talk about being part of something larger than themselves, of being connected, of being generative. It become quite clear that, for many, their experiences as part of truly great teams stand out as singular periods of life lived to the fullest. Some spend the rest of their lives looking for ways to recapture that spirit." (from ''The Fifth Discipline: The Art & Practice of The Learning Organization'' ISBN:0385517254)

 * '''Kathy Sierra''': "Today, the more you try to ''prevent'' failure, the more likely you are to fail."

 * '''Jim Rough''': "The gas of a self-organizing dynamic is trust and the maintenance is the on-going conversations that build that trust. The facilitator helps assure the quality of conversation about issues that build trust."

 * '''Jim Rough''': "To assume that people need to be motivated through incentives, rewards, recognition or punishments, is to diminish them."

 * '''Goethe''': "Whatever you can do or dream you can, begin it. Boldness has genius, power and magic in it. Begin it now."

 * '''Ward Cunningham''': "If you don't think carefully, you might think that programming is just typing statements in a programming language."

 * '''Ron Jeffries''': "As most observers will have noticed, I tend to use the word 'defect' in preference to 'bug'. I do that because bugs creep in, and defects are put in. I mildly prefer 'defect' to 'error', because I find that 'error' focuses attention on the individual more than I prefer, while 'defect' helps us focus on the effect, so that we can more readily look at all the causes, not just the proximate one."

 * '''Bob Sutton''': ''Sutton's Law'': "If you think you have a new idea, you are wrong.  Someone else probably already had it. This idea isn't original either; I stole it from someone else."

 * '''Ron Jeffries''': "Of course the universe ''is'' out to get us, but it's not going to do it by passing a null to one of our methods."

 * '''Jim Bullock''': "What slows projects down the most, at least what I have seen, is activity unrelated to progress."

 * '''John Gall''', ''Gall's Law'': "A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system."  (from ''Systemantics: How Systems Really Work and How They Fail'', ISBN:0812906748)

 * '''Ron Jeffries''': "Quick and dirty solutions can get you part of the product early, but they may bog down afterwards. This might mean that we couldn't give our customer what they really need long term.  Well-factored code can be maintained indefinitely."

 * '''Michael Bolton''': "The common element between Bad Traditionalist processes and Bad Agile Processes is that both want to remove that irritating ''thinking'' part."

 * '''William Pietri''': "To me, good domain code is a formal and rigorous way of expressing the fundamental notions of the system. It's both the foundation for the rest of the structure and the way I communicate with fellow developers both current and future."

 * '''Jennifer Granick''' ([[http://www.wired.com/news/columns/0,70971-1.html|Wired News]]): "The truth is, American society would not work if we had perfect enforcement of the law."

 * '''Alex Chafee''': "The model calculates; the view iterates."

 * '''Donald Knuth''': "Premature optimization is the root of all evil."

 * '''Martin Fowler''': "Making big changes where a system is broken for a while is restructuring. Restructuring is a Good Thing, but it isn't refactoring. Restructuring is something I did a lot, till I saw how Kent refactored his code: taking steps that were laughably small. I noticed he went faster, tended not to get into trouble, and if a test broke he knew quickly and could use diff debugging to help fix it fast."

 * '''Steve M''''''cConnell''': "Good code is its own best documentation. As you're about to add a comment, ask yourself, 'How can I improve the code so that this comment isn't needed?' Improve the code and then document it to make it even clearer." (from ''Code Complete: A Practical Handbook of Software Construction'', ISBN:1556154844)

 * '''Donald E. Knuth''': "Instead of imagining that our main task is to instruct a computer what to to, let us concentrate rather on explaining to human beings what we want a computer to do."

 * '''Barry Boehm''': "Agile methods derive much of their agility by relying on the tacit knowledge embodied in the team, rather than writing the knowledge down in plans."

 * '''Brian Kernigan''': "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it."

 * '''Martin Fowler''': "Any fool can write code that a computer can understand. Good programmers write code that humans can understand." (from ''Refactoring: Improving the Design of Existing Code'', ISBN:0201485672)

 * '''Frederick P. Brooks''': "The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures."

 * '''Andrew Hunt and David Thomas''': "Some things are better done than described....Here's a challenge for you. Write a short description that tells someone how to tie bows in their shoelaces. Go on, try it!" (from ''The Pragmatic Programmer: From Journeyman to Master'', ISBN:020161622X)

 * '''A. A. Milne''': "Here is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head. It is, as far as he knows, the only way of coming downstairs, but sometimes he feels that there really is another way, if only he could stop bumping for a moment and think of it. And then he feels that perhaps there isn't."

 * '''C.A.R. Hoare''', in ''The Emperor's Old Clothes'', Turing Award Lecture (27 October 1980): "At first I hoped that such a technically unsound project would collapse but I soon realized it was doomed to success. Almost anything in software can be implemented, sold, and even used given enough determination. There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars. But there is one quality that cannot be purchased in this way---and that is reliability. The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay."

 * '''J.D. Hildebrand''': "I once had a therapist tell me in confidence that he didn't really believe in change. I think he's right--people don't change.  Sometime very early in life you are given the keys to a great big house. One room is full of learning, another full of patience, there's a closet full of mechanisms that turn frustration into anger, whatever your personality is.

Their inability to know where or how to refactor, along with their ignorance of patterns, will yield code that is bloated and badly designed. However, that code will be tested and the test suite will serve as a speed-promoting safety net.  The team won't ever have a fast velocity if they don't learn to be better programmers, but they will produce a system and be far ahead of the inexperienced teams that let QA write the tests."

 * '''(''apparently not'') Petronius Arbiter''', 210 BC: "We trained hard ... but it seemed that every time we were beginning to form up into teams we would be reorganized ...

 * '''Ron Jeffries''': "As long as you always keep an open mind, that's what counts.  That way you can be sure you don't hear things that aren't being said, and do hear what is being said. This third sentence suggests that the second sentence may be false and that the first sentence may offer a reason why."

 * '''S. J. Gould''', ''Wide Hats and Narrow Minds'': "... But if we laugh with derision, we will never understand.  Human intellectual capacity has not altered for thousands of years so far as we can tell.  If intelligent people invested intense energy in issues that now seem foolish to us, then the failure lies in our understanding of their world, not in their distorted perceptions.  Even the standard example of ancient nonsense -- the debate about angels on pinheads -- makes sense once you realize that theologians were not discussing whether five or eighteen would fit, but whether a pin could house a finite or an infinite number."

You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds.  There is only one thing for it then -- to learn.  Learn why the world wags and what wags it.  That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting.  Learning is the only thing for you.  Look what a lot of things there are to learn."

Verbs have to agree with their subjects.  Proofread carefully to see if you words out.  If you reread your work, you can find on rereading a great deal of repetition can be avoided by rereading and editing.  A writer must not shift your point of view.  And don't start a sentence with a conjunction.  (Remember, too, a preposition is a terrible word to end a sentence with.) Don't overuse exclamation marks!!  Place pronouns as close as possible, especially in long sentences, as of 10 or more words, to their antecedents.  Writing carefully, dangling participles must be avoided.  If any word is improper at the end of a sentence, a linking verb is.  Take the bull by the hand and avoid mixing metaphors.  Avoid trendy locutions that sound flaky.  Everyone should be careful to use a singular pronoun with singular nouns in their writing.  Always pick on the correct idiom.  The adverb always follows the verb.  Last but not least, avoid cliches like the plague; seek viable alternatives."

 * '''Stephen Hawking''': tells the story of an elderly woman who confronted Bertrand Russell at the end of a lecture on orbital mechanics, claiming she had a theory superior to his. "We don't live on a ball revolving around the Sun," she said, "we live on a crust of earth on the back of a giant turtle." Wishing to humor the woman Russell asked, "And what does this turtle stand on?" "On the back of a second, still larger turtle," was her confident answer. "But what holds up the second turtle?" he persisted, now in a slightly exasperated tone. "It's no use, young man," the old woman replied, "it's turtles all the way down."
