1. Introduction
1.1 Purpose
This Software Verification and Validation Plan defines the approach, activities, and responsibilities for verifying and validating the Patient Portal System to ensure it meets specified requirements and is fit for its intended use.
1.2 Scope
This plan covers:
- All software components of the Patient Portal System
- Integration with external systems (EHR, Identity Provider)
- Security and compliance verification
- Performance and reliability validation
1.3 Definitions
| Term | Definition |
|---|---|
| Verification | Confirmation through examination and provision of objective evidence that specified requirements have been fulfilled |
| Validation | Confirmation through examination and provision of objective evidence that the requirements for a specific intended use are fulfilled |
| V&V | Verification and Validation |
| SRS | Software Requirements Specification |
| STR | Software Test Report |
