Why is it called Drum-Buffer-Rope?
- The Drum refers to the critically constrained resource that beats the rhythm to which the whole organisation is synchronised.
- The Buffer is a time-based shock absorber that takes account of process variability to ensure that the Drum is never starved of work. This protects the throughput of the organisation.
- The Rope controls the release of work into the system in such a way that the Drum is fully utilised and there is no unnecessary creation of work in progress.
