Requirements Engineering

Start with establishing requirements

Begin with the mind map “Establishing Requirements.” It asks what a project is trying to achieve, how it can achieve it and why it matters. It also looks at understanding users and producing a set of rules to start designing.

Next, open “Identifying need and establishing requirements.” This map considers understanding users, their work and their context. Use the two maps to compare how they describe the work of establishing requirements.

Explore elicitation

The “Requirement Elicitation” mind map introduces functional and non-functional requirements. It describes functional requirements in terms of how a system should react or behave, and non-functional requirements as constraints on services.

Continue with “Requirements Elicitation” to see types of requirements, including business, stakeholder and transition requirements. The “Requirements” flashcards offer questions about why elicitation is difficult and about the cyclical elicitation and analysis process. Read a map first, then use the cards to recall the ideas without looking back.

Check requirements with validation maps

The “Requirements Validation” mind map focuses on checking a requirements document. Its branches include completeness and consistency, conflicts, technical errors and ambiguity. It also introduces validation methods and requirement reviews.

Compare it with “Requirement Validation,” which includes raw requirements, validation and a final draft. As you study, look for the checks that appear in both maps and note where their coverage differs.

Use the page within the unit

Requirements Engineering is a section of the Software Requirements and Design unit in Computing and ICT (programming, computer science, digital skills, educational technology). The maps and flashcards offer starting points within this section, alongside the listed quizzes and note.

After working through a map, try the “Software Engineering” quiz and use its questions to guide another look at the resources. Choose a map or quiz and work through it at your own pace.
