Introduction

This model and its associated documentation has been produced as an aid to those involved in the production of Application Protocols for the Process Industries in the STEP (ISO 10303) standard. It provides an overview of the main activities and data flows associated with the life cycle of process plant. It is emphasised that the aim of the model is not completeness but communication to those who require to understand the main interactions between the major phases of engineering activities in the process plant life cycle. With this aim only the major data flows are shown and minor data flows and feeds back to earlier phases of the life cycle have been ignored. The activities are depicted as serial streams for the process and engineering activities. However, the activities may be ignored, combined or performed concurrently dependent upon the requirements of the task to be undertaken.

The model will be made available in four forms, a paper document (this document), an electronic version of this document in Microsoft Word for Windows1 version 3.0 or 6.0 or Wordperfect 5.12 for DOS, a Microsoft Powerpoint file suitable for version 3.0 or 4.0, a coloured wall chart (A0) and a Microsoft VB basic program.
