Process decomposition: Level 3

Depending on the assignment it can be useful to make a hierarchical process decomposition. In the ideal way one should make a process decomposition with the organization objectives as a starting point. Starting at the high level organization objective, you should ask the question ”WHAT” functions should we perform to the achieve this objective (at a high level e.g. inbound logistics, operations, marketing & sales and service). The next step would be to ask per underlying function (e.g. inbound logistics) what the objective is and what functions we should perform to achieve this objective. In the end the result is a kind of tree of functions, giving an overview of WHAT functions are performed. This model is implementation independent and says nothing about by whom, when or how functions are performed! One should stop with decomposing when one reaches a function level that employees recognize as elementary processes.
