Process definitions are high level descriptions instead of rigid workflows : Processes can only be defined up to a certain level of detail, and it is difficult to provide low level work instructions or to automate decisions. Because they cannot be formalised in detail, process simulation is rarely possible. Decisions are highly subjective and too complex to be expressed in a formal language, as they are taken based on intuition and not on rigid business rules.
For a technical writer a flowchart can be a very useful tool to illustrate various operations and processes. Before you start your next project, see if you can illustrate the process via a flowchart.
