What is the hardest problem of
agile adoption?
Selling ideas to…

Large WIP problem
Single
priority
• Improves
cycle time for
some projects
• But makes
bottleneck
even worth
Pull system
• Improves Cycle
Time
• Decreases
Multitasking
Simulation model
• Shows everything in dynamics
• Explains ideas
• Validates decisions
• Is easy to believe in
• Is really cool thing to play with
Thanks! Questions?
