Understanding Work-in-Process Age and Little's Law

It's time to unpack another assumption of Little's Law, and this time we're looking at how and why the average age of WIP must not be meaningfully changing.

In this episode, Host Phil Ledgerwood talks through this assumption and its upsides/downsides.
