Managing flow for fast and predictable delivery A preliminary report
Everybody wants to be faster and more predictable
Just a bit of context...
10 Scrum development teams 60+ people Credit, Document Mgmt., BPM
... a few concepts...
Cycle time. The number of days it took from starting
to work on an item until it was pushed into production. Analysis Development Acceptance Production
Work in Progress Age. The number of days that passed
since we started working on an item. Analysis Development Acceptance Production
Work in Progress. The number of items we have started
to work on but are still not finished. Analysis Development Acceptance Analysis Development 2
Alright, moving on… faster!
We decided to believe in Little’s Law and Flow.

Cycle Time
Cycle Time “Cleaning up”
Cycle Time Best since Jan 2017
26% improvement of cycle time from January 2019
% On Time “Cleaning up”
% On Time Best since Jun 2018
43% improvement of delivery on time from January 2019
The Takeaways
Manage your WIP… Keep as few circles as possible
Pull! Pick these ones first, and then pull from the
ones on the immediate left.
Keep your items young! Don’t let them go up!
And that’s about it.
