The BizADS meta-model includes a process model. This was used to assess various modelling techniques to see whether the model could support them. The most common technique uses "Black Box/White Box" decomposition to support successive elaboration of a process. Most tools and modellers treat this process modelling approach as one of recursive processes. However the boundaries for elaboration are typically arbitrary (process, sub-process and activity being example levels of decomposition) and while the "White Box/Black Box" approach suits top level drill down, it does not support any form of roll-up or assembly of decomposed processes. As it is quite common for the process analysis to start at an arbitrary point is is important to be able to work from the middle out. Using a combination of "Black Box/White Box" technique and structural analysis of the Performer, it is possible to provide richer process model tooling support. The technique provides a less arbitarary basis for decomposition and allows automatic roll up of procceses. The technique separates the Process Definition, from its analysis view. This allows tooling to handle handle change of modelling persepective from the process model itself, unlike techniques built solely on recursive processes.where modelling persective changes are not explicity supported. The combination of the using the performer struturing and "Black Box/White Box" (Performer based Black Box/White Box Process Modelling) is introduced. The analysis also looked at how typical process hiearchy diagrams would be represented using the BizADS classification secheme or as a reprentation of a process control hiearchy.
