Lean Software Development, An Agile Toolkit by Mary and Tom Poppendieck, ISBN 0-321-15078-3.

See LeanProgramming

This book models programming as an assembly line. Each piece on the line is a change request. The goal of software development is to treat the assembly line as a ValueStream, and minimize the time a request spends on the line. That requires distributing control to the workers, and mistake-proofing all aspects of the line.

Inventory, in software development, per the Poppendiecks, is partially done work. Partially done work (SoftwareInProcess) is an investment that has not yet yielded a return. And not even been deployed to where it could yield a return. Therefor minimize inventory by frequently delivering small complete units of working functionality to the customer.
