Gathering and documenting requirements is considered the most important phase of the software development lifecycle. This phase of software development is supported by a variety of techniques for defining the requirements of a software system. Examples of these techniques include plain English statements about inputs, processing, and outputs, UML use cases, and entity-relationships diagrams.

In this discussion, you will select two software requirements techniques of your choice. You will analyze these two techniques and the situations in which they are used. You will then provide an example of the outcome (either textual or visual) of each of the techniques you selected explaining the requirements information they give.

To prepare for this discussion:

1) Review the module's learning resources and its references.
