3 Business process elements If you dip into a company and ask a non-IT person to describe how the business works, he or she will most likely immediately describe a business process. A business process is a sequence of activities aimed at producing something of value to the business. The individual explaining the business may not be aware of the complete process and so may be describing a process fragment, but even that will still have all the same hallmarks; a subprocess is a process too! The terminology varies a little from place to place, but most business processes display a similar set of features.
What would it mean if this really could be done? Most obvious is the potential for a huge reduction in the time needed to develop a system, once the requirements have stabilized. What might have taken weeks or months could be done in minutes or hours. This might be partly offset by some additional time needed to structure the business description, but the net gain is still considerable. Alongside this, there would be a shift in the staffing profile needed. Although a small increase in the number of analysts might be needed, very large reductions in the numbers of developers and testers would certainly be realized.
Neither extreme delivers what we want. Over the years, a variety of notational styles have been proposed, but recently most attention has been concentrated on the Unified Modeling Language (UML). Dozens of books describe UML, so here we'll consider only the features that are most relevant to business modeling. Just to be absolutely clear, you don't have to adopt UML. If you prefer something else that does the same job, fine. However, if you don't have any commitment elsewhere, the widespread support for UML makes it a fairly safe choice as a baseline.
