Workflow Detail: Define the System
Purpose 
The purpose of this workflow detail is to:
- Align the project team in their understanding of the system.
- Perform a high-level analysis on the results of collecting stakeholder needs.
- More formally document the results in models and documents.
Typically, this is only performed in iterations during the inception and elaboration phases.
Problem Analysis and Understanding Stakeholder Needs create early iterations of key system definitions, including the Vision document, a first outline to the use-case model and the Requirements Attributes. In Defining the System you will focus on identifying actors and use cases more completely, and add Supplementary Specifications.
How to Staff
All members of the project team should participate.
Work Guidelines
The following are sample techniques that can be applied:
Example Project
In the inception phase, Lisa and Harry act as system analysts. In this step, they get together to analyze the results of their meetings with stakeholders and customers and to agree on a first outline to a use-case model and Supplementary Specifications.
Since both Lisa and Harry act as system analysts, they both share responsibility for the resulting artifacts. Lisa is the owner of the use-case model, while Harry owns the Glossary and the Supplementary Specifications.
