GETTING ORGANIZED

Move from Fire Fighting to Fire Prevention
Understand proactive/reactive ratios
Make causes visible
Move towards prevention
Queuing theory

• Ringfence Fire Prevention
– Fires aren’t a desired business outcome!
– Keep focus (and disruptions to a minimum)
• Make fires and their sources visible
– Firemen can become unintentional arsonists
– Expedite means it is a fire!
• Reduce flammable fuel
– Reduce batch sizes
– Big batches can become all-engulfing infernos!
Create the fire line

Can take on tasks if idle, but lower priority
Queue master

All work goes into flow
via the Queue Master
Work is prioritized
by the Queue Master
Rules

Week long iterations (at most!)
Queue Master position should
rotate at regular iterations
Iterations

Review queues and workflow
Go through blocked tasks
Review flow problems
Archive Done
Team iteration review
Great place to go over A3s!
Retrospective

Choose which improvement items to
action
Review any key upcoming/scheduled
activities
Sort out any change alignment challenges
