Scrum - jeff sutherland

• Orient, Observe, Decide, Act
• Great Teams are cross-functional, autonomous, and empowered
• Shu Ha Ri: First, learn the forms and the rules, and once you've mastered them make innovations. In a heightened state of mastery, discard the forms and just *be.

Teams

• Improving team performance has much more impact than improving individual performance
• A team must have every skill needed to complete the task
• Small teams achieve more than big teams (7 seems to be the magical numbers)

Time

• Break down work into tasks that can be accomplished in small sets of time, for example 1 week, 2 weeks, etc. You can call that a Sprint
• At the end of each sprint, have something that can be demoed: showed, driven, etc.
• Everyone knows everything. Saturate the communication channeles so everyone has the same information to make decisions.
• Daily check-in is more than enough.

Waste

• In Japanese:
  • muri: waste through unreasonableness
  • mura: waste through inconsistency
  • muda: waste through outcomes
• In PDCA:
  • Plan: avoid muri
  • Do: avoid mura
  • Check: avoid muda
  • Act: do all that
• Multitasking does not increase productivity. The secret of Scrum is that it allows people to focus.
• Half-done is not done at all. Focus, finish, move on.

Planning

• User story: As a <who/role>, I want (or need) < what > so that < why/business value >
  • As a starship captain I want a system that automatically logs dates so that I can focus on the important observations.
• System story: <Action verb> <subject> so that <who> gets <what> or <goal> is achieved.
  • As a <Light beer drinker>, I want <a beer with lower alcohol by volume ABV> so that <I will consume fewer calories>
  • <Run the beer in tank three> <through the evaporator> so that <a lower abv> is achieved.
• Only plan what you need. Set a direction and goal, but plans are like maps: an imperfect representation of the terrain.
• We are very bad at estimating, so don't try to estimate without knowledge.
• Planning Poker
