Introduction to Requirements Engineering

Framework for Requirements Engineering

• Identifying the Requirements Engineering rationale
• Planning and estimating requirements
• Identifying the business rationale and inputs
• Crafting the business case
• Creating the Terms of Reference or Project Initiation Document (PID)

Building the Requirements

Stakeholders in the Requirements Process

• Project Stakeholders
• Business Stakeholders
• External stakeholders

Requirements Elicitation

Types of knowledge

• Explicit knowledge and ignorance Identifying tacit knowledge and ignorance

Eliciting requirements from stakeholders

• Planning elicitation meetings Choosing the right people to interview

Applying elicitation techniques

• Selecting the best interview methodology Constructing questions that deliver results

Requirements Engineering Modelling Techniques

Why model requirements?

• Generating questions
• Defining business rules
• Cross-checking for consistency and completeness

Modelling the business context for the system

• Developing a model to represent system processing requirements
• Interpreting a data model

Documenting Your Requirements

Documentation styles and levels of definition

• Writing standard requirements
• Employing user stories and use cases

Creating a Requirements Catalogue

• Identifying necessary attributes
• Writing a requirements description
• Non-functional requirements

Requirements Analysis

Prioritising and packaging requirements for delivery

• Analysing and prioritising business needs
• Allocating requirements

Organising requirements

• Optimising business value
• Evaluating dependencies between requirements

Ensuring well-formed requirements

• Removing overlapping requirements
• Identifying and negotiating conflicts between requirements
• Removing ambiguity
• Ensuring feasibility and testability
• Prototyping requirements
• Verifying requirements

Validating Requirements

Applying validation skills

• Selecting the best validation methods
• Validation checklists

Types of reviews

• Reviews, walkthroughs and inspections
• Stakeholders and their areas of concern

Requirements Management

Dealing with changing requirements

• Types of changes
• Frequency and magnitude of changes

The importance of traceability

• Vertical traceability (to business objectives)
• Horizontal traceability (from origin to deliver)
• Traceability and ownership
