Hi Julian

Probably the most effective tool at the moment is Corporate Modeller from Casewise. It is repository based - has a database in which all objects are held for re-use on other diagrams - and can model all facets of the business.

You can find out more about the Integrated Modelling Method at http://integrated-modeling-method.com

A comprehensive article listing the benefits of the Process Model, which can provide vital business benefits. However, Process Modelling does come with some vital health warnings.

Health Warning 1: Build the Function Model First
All processes are derived from Business Functions so, before you start modelling processes, build your function model. This is far easier and faster to build and, in a single diagram if required, will provide you with a complete view of any business.

Health Warning 2: Never Decompose Processes
All decomposition should be done in the Function Model - where it can be done easily. Decomposing process models results in the need for up to three times more diagrams than are necessary. You can also miss out up to 30% of the business using this approach.

Health Warning 3: Beware Building the "As Is" Model
It is true that all businesses should have all of their essential processes modelled. However, if the business is about to undertake a major change, then modelling the "As Is" processes is a huge waste of time as it actually represents what should NOT be done in the business (if it was the business would not be changing!). Better at this stage to model what the business OUGHT to be doing, starting with the business functions.
