Introduction to powerdesigner Requirement Analysis Model rqm

What is rqm?

A requirement analysis model is a model that records a requirement document. It helps you list and define user requirement actions that must be performed during software development.

The requirement model displays three view types:

• Requirement document view: Lists and defines requirements that must be met during development

• Traceability matrix view: Link View for other external files, design files, or other special requirements

• User allocation matrix view: links are associated with users and groups during development requirement analysis.

Why rqm?

The requirement analysis model provides a convenient and practical method to manage requirements. It is a hierarchical list of requirements. You can convert a MS Word document to a required document view, which allows you to easily modify the content and requested hierarchy (with the browser Tree View and Attribute Table ). In addition, the requirement analysis model interacts with other models through the import/export wizard and traceability matrix view. Finally, you can use the user allocation matrix view to associate the user-requested allocation.
