Reinertsen argues that "invisible and unmanaged queues are the underlying root cause of poor product development performance". These queues form because, when a process with variability is loaded to high utilization, work products spend most of their cycle time waiting. Moreover, these queues are typically "unmeasured and unmanaged".
When a highway reaches 100% capacity, traffic grinds to a halt. The same phenomenon occurs in product development. principles of product development flow pdf
When you look for a , you are essentially looking for a guide to reducing "inventory" (unstarted or half-done work). Reinertsen argues that "invisible and unmanaged queues are
A failure in a small batch is far less catastrophic than a failure in a massive release. When a highway reaches 100% capacity, traffic grinds
Reinertsen’s science-based approach distinguishes his work from fads. He explains the "mechanism of action" behind methods, showing why they work and enabling their application to different situations.
Teams establish clear formulas balancing development cost, product cost, schedule, and performance, enabling decentralized decision-making.
