Chapter 6 - Modeling system requirements with use cases. In this chapter you will learn about the tools and techniques necessary to perform usecase modeling to document system requirements. Capturing and documenting system requirements have proved to be critical factors in the outcome of a successful information systems development project. Documenting the requirements from the perspective of the users in a manner that they can understand promotes user involvement, which greatly enhances the probability for the success of the project. | Chapter 6 Modeling System Requirements with Use Cases Teaching Notes This repository of slides is intended to support the named chapter. The slide repository should be used as follows: Copy the file to a unique name for your course and unit. Edit the file by deleting those slides you don’t want to cover, editing other slides as appropriate to your course, and adding slides as desired.

An Introduction to Use-Case Modeling One of the primary challenges is the ability to elicit the correct and necessary system requirements from the stakeholders and specify them in a manner understandable to them so those requirements can be verified and validated. Teaching Notes This slide explains the industry problem that this material addresses. If possible, the instructor should share real-life experiences in misunderstood or mis-specified system requirements. To illustrate the inadequacy of data and process models, show the students some of the models from chapters 7 and 8. Ask them as novices if they can understand them.
