Lean Software Development

Some study notes while reading about Lean Software Development:
  • Adapted from Lean Manufacturing, Toyota Production System;
  • Originated in the boot "Lean Software Development" by Mary Poppendieck and Tom Poppendieck
  • Principles:
    • Eliminate waste
      • Extra features
      • Economies of scale: focusing on high utilization is almost guaranteed to lower it
      • Cross boundaries

    • Amplify leaning
    • Decide as late as possible
    • Deliver as fast as possible
    • Empower the team
    • Build integrity in
    • See the whole

  • Two pillars
    • Continuous improvement
    • Respect for people

  • The responsibility lies, not with black belt specialist, but with the leadership hierachy that runs the operation and they are teachers and coaches;
  • The essence of (the Toyota system) is that each individual employee is given the opportunity to find problems in his own way of working, to solve them and to make improvements;
  • Challenge everything, dissatisfied with status quo
  • Kanban
  • Kaizen
    • spread knowledge
    • small, relentless
    • retrospectives
    • 5 whys
    • eyes for waste

  • Share rather than enforce practices
