Episode 180: Extreme Programming & 3X Explained with Kent Beck

Craig and Tony are at YOW! Conference in Brisbane and have a rockstar moment and catchup with Kent Beck, the creator of Extreme Programming, the pioneer of xUnit and author of numerous books including “Extreme Programming Explained” and “Test Driven Development“:

  • Extreme Programming (XP) was born at Chrysler by letting go of conventional wisdom and pushing practices to eleven
  • Software development is a social process, not a sum of individuals process
  • Nobody cares about certificates, we care about competence
  • It’s time for a renaissance and reboot of XP – this time it needs to be inclusive and no barriers to entry
  • We know how to make a difference – it starts with execution and continues to empathy
  • Big tent agility can become an excuse not to tackle hard problems
  • “Not thinking about all the legs on the stool leaves you sitting on the ground” – some of the legs of agility require a fundamental change in belief
  • As a programmer am I responsible for my code running – once you have that belief, unit testing falls out of that
  • TDD is a set of feedback loops and an incentive system to encourage confidence and certainty
  • Test, Commit, Revert takes TDD further – run the tests, if they pass you commit and if they fail you revert the changes – incentive to take small steps
  • “Silence is the sound of risk” – you need feedback (unless you are perfect)
  • XP was a better product, but it lost (round one)
  • Electric or blade?
  • If XP starts with the premise that we want a process that anyone with talent and skill can contribute and grow at maximum velocity, the rest will take care of itself
  • Agile as a name is so attractive, nobody doesn’t want to be agile – the brand of Extreme Programming means if you are not extreme you are not going to say that you are
  • The fundamental question to ask first is “what do we have to lose” – if you have nothing to lose you need to try short and crazy experiments to find things nobody else is doing
  • 3X model (explore, expand, extract) – YOW! keynote “3x Explore, Expand, Extract” – depends which part of the curve you are on as to which tools in your bag you should use, rules of the game change depend on whether you are looking for a new source of value (explore), growing fast and trying to keep up (expand) or continue growing to pay for new explorations (extract)
  • poker vs software development
  • we will win with community and inclusion
