Excessive Work in Progress (WIP) is the enemy of flow. By setting limits to work in progress we can enable greater flow.

Limit Work In Progress
Traditional management thinking treats all demand as equal. There is work to be done and people who do the work. Failure Demand is demand that originates from a failure to have done something right in the first place. Not all productivity is desirable.
What is Failure Demand?

!Agile team produces growing velocity but, as they speed features out the door, bugs are introduced. When bugs come into the backlog they’re assigned velocity points. It is theoretically possible, therefore, to have a team producing zero value while increasing velocity fixing bugs.
Product Development Example

● In order to keep developers typing at maximum utilization, we create teams to absorb the failure demand caused by developers typing at maximum utilization. These teams often have unlimited WIP and must consume an unending stream of demand. This also hides the problems from the people creating them.
“Dumpster Teams”

!In general, reliability is the ability of a person or system to perform and maintain its functions in routine circumstances as well as in hostile or unexpected circumstances. In the case of emergency services, reliability looks at actual incident history data to measure historical performance in accordance with adopted performance measures.
!A unit unavailable for response provides no service to the community. The unit may be out of service for a multitude of reasons including; another emergency response, training, maintenance, etc. If a unit is not available 80% of the time, it is not reasonable to expect the unit to perform at the 80th percentile.
!…. Poor availability negatively influences response times.
