The Unified Process

The Unified Process

The Unified Process includes business process modelling and domain modelling as part of requirements analysis. The business process modelling notation is the busi ness use case notation introduced above, and the domain modelling is based on the object modelling notation. These models are then used as the input to the develop- ment of use case models for the system, which is considered the next and most substantial part of requirements analysis. The Unified Process approach is funda- mentally the same as the one described here, but less prescriptive and detailed

8.9 Further Models and Notations for Business Modelling

The activity modelling described above is much more comprehensive and detailed, and can include specification of the activity behaviour and parallel flows. However, the level of detail needed for business modelling is probably as much as is included here Object modelling incorporates operations and data, and it may be useful to capture data at this stage in the objects. We shall later meet sequence and collaboration diagrams Very occasionally these are of use, particu larly when describing complex interactions between parts of a business.

You need to beware, however, not to make the business model too detailed, and not to bring into the business model the details of the system that is to be developed. Business models should be about the way a business operates. Inevi tably today when a system is an embedded part of a business, this will involve same system aspects. Thus the business model should be enough to understand the business for the purposes of describing the way a system fits into the business. and no more

ICANDO Bulk Chemical Ordering

8101 BUSINESS PROCESS MAP ICANDO Chemicals want a new system to improve the sales process. In particular, their business plans imply much tighter integration between sales and manufac ture. By special discounting structures for advanced orders, it is planned to increase the number of deliveries direct from the production line to reduce trans- port warehouse costs and the locking up of Metalwho valuable working capital in stocks. Therefore the process map has been extended to cover the processes in manufac turing as well as sales. Figure 8.17 covers a representative set of business
