© Tasktop 2018 Why Flow Distribution: Visualize the tradeoffs A decision to do one thing is a decision to delay something else. Provoke necessary discussion on priorities. Balance work types based on biz strategy.

Slide 10

Slide 10 text

© Tasktop 2018 Why Flow Load: WIP is a leading indicator Flow Load: All the partially completed work. All the work-in-progress (WIP) in the value stream Benefit: Provokes convo’s on WIP limits that act as enabling constraint.

© Tasktop 2018 Dominica DeGrandis Thief Too much Work-in-progress (WIP) High WIP means that other items sit waiting for service longer. The single most important factor that affects queue size is capacity utilization.

Slide 12

Slide 12 text

© Tasktop 2018 Dominica DeGrandis Thief Too much Work-in-progress (WIP) Queuing Theory allows us to quantify the relationship between wait times and capacity utilization. Wait times increase exponentially as utilization approaches 100%. Queuing Theory: Applied statistics that studies waiting lines If the goal is speed, consider managing work by queues. http://reinertsenassociates.com/books/

Slide 14

Slide 14 text

© Tasktop 2018 90th percentile filtered on features Benefit: Answer the Q: “What’s the probability of completing work in x days?” Why Flow Time: Improve predictability Be approx. right instead of exactly wrong.

Slide 15

Slide 15 text

© Tasktop 2018 Flow Time – How Yes, let’s do this! Flow Time: The duration from when work enters the value stream to its completion.

Slide 16

Slide 16 text

© Tasktop 2018 Flow Efficiency: The percentage of time where work is in an active state vs. a wait state. Why Flow Efficiency - Expose wait time Benefit: Learn how much wait time exists in Value Stream to drive discussion to improve decisions on prioritization, capacity & utilization.
