root cause analysis

Analytical methods to determine the core problem(s) of an organization, process, product, market, etc. See: current reality tree, five why's, stratification analysis.

In the theory of constraints' drum-buffer-rope system, the rope consists of the minimum set of instructions to ensure that (1) nonconstraint resources are used (and not overactivated or misallocated); and (2) material is released into the system and flows to the buffers in a way that supports the planned overall system throughput.

The process of converting the master production schedule into requirements for key resources, often including labor, machinery, warehouse space, suppliers' capabilities, and, in some cases, money. Comparison to available or demonstrated capacity is usually done for each key resource. This comparison assists the master scheduler in establishing a feasible master production schedule. Three approaches to performing RCCP are the bill of labor (resources, capacity) approach, the capacity planning using overall factors approach, and the resource profile approach. See: bill of resources, capacity planning, capacity planning using overall factors, product load profile, resource profile.
