Document History

1. Introduction to the Activity Model

This Activity Model (Part 3 of Release 1.1 of the CIS, has been completely redrawn since CIS/1.0, so that it is now in-line with the application activity model (AAM) of ISO/WD 10303-230: 1996(E) N551, currently under development at Leeds University. It is provided to aid in understanding the scope and information requirements defined in the CIS. The model is presented as a set of definitions of the activities and the data and a set of activity figures (figures 1 to 7). The Activity Model covers activities that go beyond the scope of this release of the CIS. Activities and data flows that are out of scope are italicised. The viewpoint of the Activity Model is that of a building-project manager.

The purpose of the Activity Model is to identify the tasks of each person or company and identify the information flows between each activity. This is then used to develop an information model for all or part of structural steel frame.

This Activity Model was originally derived as a subset of a 30-page model developed by the SERC funded CI-PM Project. Many models have contributed to this Activity Model, including the Generic International Functional Model (GIFM) and Activity Model of the Target System Architecture (TSA) developed in the early years of the CIMsteel Project.
