Why map business processes?
We use process maps to ‘tell the story’ of the operation we are looking at, and then to help describe how to make it work better. This is widely known as Business Process Improvement.
As most people prefer pictorial visualisation of concepts, we can tell the story using the process map in the form of a flow chart or flow diagram.
Process mapping also allows us to structure the story in chunks that can be better represented, understood and evaluated. In the same way as a book is structured into the book concept (title), the associated volumes (often only one), its sections, chapters and paragraphs, the flow of work through an organisation is equally represented by its business units, its regions, departments, functions, processes, procedures (work instructions), forms / templates / other information artefacts, and finally its data fields.
