This lesson builds on the introduction to spatial system development from the previous lesson. Specifically, this lesson provides a more detailed look at the phases that are collectively called systems analysis. This analysis process reinforces the information system building blocks that were developed previously. Included is a look at the requirements gathering, and analysis concepts, tools, and methods. Whitten addresses the seven common fact-finding methods (Sampling, Research, Observation, Questionnaires, Interviews, Prototyping, Joint Requirements Planning) which are introduced as a means to discover requirements.
Lesson Learning Objectives:
- Evaluate the importance of the human component to design.
- Describe systems analysis.
- Describe the difference between functional and nonfunctional requirements.
- Explain when to use the key system analysis approaches.
