What are the implicit rules of Agile?• Must have co-located team members

• User stories must be written in ‘As a… I want… ‘ template format

• Testing is fully automated

• Agile requires a full time Coach

• Always start with sprint zero

• You cannot coach yourself

• It’s most efficient with T-shaped people

• Testing cannot be done successfully by separate people

• Scrum Masters should be technical

• Scrum Masters should not be technical

• Mondays are a bad day to start an iteration

• Estimate in story points

• Don’t estimate at all

• Full time Product Owner

• It’s the system not the people

• It’s the people not the process

• Retrospectives should be game-led

• Building in iterations is more efficient

Why did I break the rules?

11/3/17

25


Challenging rules is necessary to continuously question the

appropriateness of our practices


Agile gives the perception of openness to change about

everything apart from itself.

This is our fault.

11/3/17

26


Do we know why we are doing the things that we are doing?


Close your eyes

• Imagine an implicit rule in your team or organisation

• What value are you getting from the rule that you are following?

• What positive impact could happen if you challenged that rule in a drastic way?

• Share with your neighbour
