One of the biggest mistakes a leader can make is to stifle initiative.

#Kanban systems use local WIP constraints; #TheoryOfConstraints systems use global WIP constraints.

Local feedback loops are inherently faster than global feedback loops.

Control the decision logic, not the decision.

"Many people assume that holding meetings on-demand will provide faster response time than holding them on a regular cadence. This would be true if everyone was just sitting idle, waiting to be called to a meeting."

#ThePrinciplesOfProductDevelopmentFlow: Second Generation Lean Product Development (p. 206). Donald G. Reinertsen. Kindle Edition.

Regular cadence enables smaller batch sizes BUT only if you are required to deliver progress at the cadence.

"Instead of killing projects, many companies mistakenly starve them for resources, barely keeping them alive. This creates the legendary zombie projects—the unliving and the undead. They are not good enough to get sufficient resources, but they are not bad enough to kill. Zombie projects destroy flow. Kill the zombies!"

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"...the kanban system makes no assumption about the location of bottlenecks...The feedback in a kanban system is also inherently faster than that of a TOC system."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"...adjustments to batch size are too slow to respond to the short-period random variation in product development flow."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"Batch size reduction can enable us to shorten cycle time, often by an order of magnitude or more, without changing capacity utilization."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"It is usually better to improve iteration speed than defect rate."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"A buffer converts uncertain earliness to certain lateness. Thus it is generally a bad idea to trade cycle time for reduced variability in cycle time."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"Watch the work product, not the worker... In #ProductDevelopment, our greatest waste is not unproductive engineers, but work products sitting idle in process queues... In #ProductDevelopment, our problem is virtually never motionless engineers. It is almost always motionless work products."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"We simply have no business trading money for cycle time if we do not know the economic value of cycle time."

Don Reinertsen, #ThePrinciplesOfProductDevelopmentFlow

"This is the great lesson of the #ToyotaProductionSystem. The 100-fold improvement in manufacturing cycle times was not achieved by finding #bottlenecks and adding capacity to the #bottlenecks. It was achieved by reducing #BatchSize."

Duration doesn't matter for #prioritisation? Someone hasn't read #ThePrinciplesOfProductDevelopmentFlow

Realised that I picked up the phrase "zombie projects" from #ThePrinciplesOfProductDevelopmentFlow
