Chapter 6: Requirement Validation
Validation and Verification
Validation
Checking if the artifacts are appropriate or not
Verification
Provide the correctness of software or specification
Quality assurance
Constructive
prevention of defects
Analytical
checking of quality after the creation
Validation
Checking input, execution, and output of the requirement engineering core activities
Goal
checking output fulfill defined criteria
checking input fulfill defined criteria
checking execution adheres to process definition and activity guideline
Risk Not validate
Error in planning, architecture, design, test and implementation
Conflict not resolved
Late error detection
Client stop trusting
Budget overrun
Quality gate
Context
Validate all facet
Validate Development Context
Validate Requirement Engineering context
Validate context artefacts
