To pull or not to pull

摘要

The Toyota Production System promotes "pull" scheduling to reduce the production of parts that do not comply to what the customer needs. The use of "pull" within software represents a radical change in the way activities are planned. This article gives two examples of the possible application of "pull" within software engineering and de-scribes a measurement tool to assess the current costs and amount of rework within a software development project. The described approach aims to help practitioners to under-stand whether to use "pull" or "push" in their organizations.
