Values Drive Development

How we develop and ship software expresses the values of our team, business & users. Many teams can’t state their driving values. The process of outlining a shared set of values can lead to enhanced team identity and help align development efforts. The inverse of this process is looking at what the team has done historically and working backward from that to find the implicit values that have driven team behavior. If we study how we spend time, money and energy, we can cultivate a picture of our values in practice. There will be a gap or dissonance between our self professed values and those visible to others from our actions. Embracing this dissonance can drive out more clarity, coherence and transparency in our future efforts.

2. Nobody ever gets everything they want from a software system.
3. Software is Complex
4. "Everything should be made as simple as possible, but no simpler." Albert Einstein
5. Compromise
6. "Under the hood, most critical software you use every day (like Mac OS X, or Facebook) contains a terrifying number of hacks and shortcuts that happen to barely fit together into a working whole." Ben Cherry
7. Fast, Good or Cheap Pick Two
8. Budget Scope Schedule The Iron Triangle
9. Tradable Quality
10. The Design Stamina Hypothesis http://martinfowler.com/bliki/DesignStaminaHypothesis.html
12. Quality is building it right Design is building the right thing
13. My biggest challenge as a developer is coding the right thing, rather than coding the thing right. Liz Koegh
14. Design > Quality
15. It doesn’t matter how well you build the wrong thing.
17. “I expect a programmer to apply the appropriate amount of rigor, discipline and excellence to any situation.” Dan North
18. Quality has a minimum acceptable threshold
19. Good enough is good enough.
20. “Alan will always do the right thing no matter how long it takes or how much it costs.” Ross Young
21. Technical Debt
22. Show me the values!
23. "We will encourage you to develop the three great virtues of a programmer: laziness, impatience, and hubris." Larry Wall
24. Laziness
25. Impatience
26. Hubris
28. 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. http://agilemanifesto.org/
29. Individuals and Interactions
30. Working Software
31. Customer Collaboration
32. Responding to Change
33. “A fanatic is one who redoubles his effort when he has forgotten his aim.” George Santayana
34. “The real goal of the methodologies is to sell books, not to actually solve anybody's problem.” Joel Spolsky
35. Fuck Software Craftsmanship
36. Next topic…
37. As aspiring Software Craftsmen we are raising the bar of professional software development by practicing it and helping others learn the craft. Through this work we have come to value: • Not only working software, but also well- crafted software • Not only responding to change, but also steadily adding value • Not only individuals and interactions, but also a community of professionals • Not only customer collaboration, but also productive partnerships That is, in pursuit of the items on the left we have found the items on the right to be indispensable.
