All relevant process information must be available e.g. examples of useful documents
could be manufacturing reports or test specification.
The individual process steps e.g. mapped in a process map are assigned unique
numbers to enable clear referencing at a later stage. In the example below the
steps have been numbered in increments of ten so that it is subsequently possible
to insert additional sub-processes (e.g. if an extra control balance is integrated into
the overall process at a later stage). The figure provides an overview of a simple
flow chart with three levels of detail (figure 10.I-2).
