Session 2.7 – Validation Strategies
Module 2: Verification & Validation | Duration: 1 hour
Learning Objectives
- Plan validation activities that mirror real user journeys and environments.
- Design UAT/pilot programs with clear success/failure criteria.
- Collect evidence (defect data, usage analytics, stakeholder sign-offs) for release readiness.
Validation Strategy
A good validation strategy answers: who validates, what scenarios they run, where (environment), and when (timeline relative to release).
Personas & Journeys
List critical user personas, capture their top tasks, and map acceptance scenarios.

Environments
Staging vs pre-prod vs pilot tenants; data sets (synthetic vs production clones).

Risk-based coverage
Prioritize validation in high-risk modules (payments, safety features, compliance).

Exit criteria
Pass/fail metrics, acceptable defect levels, performance SLA confirmations.

User Acceptance Testing (UAT)
UAT validates solutions with real users or their proxies to confirm business needs.
- Preparation: UAT charter, participant list, data setup, training materials.
- Execution: Facilitator records results, blockers, UX observations.
- Sign-off: Business/product owner approves, with documented waivers for known issues.
Roles
- UAT Lead – coordinates schedule, environment, reporting.
- Business SME – validates outcomes and edge cases.
- Recorder – logs issues/feedback in tracking tools.
Pilots & Field Trials
Field trials capture how the product behaves under real traffic, data, and operational constraints.
- Canary releases, feature flags, or limited beta cohorts.
- Monitoring hooks (usage analytics, error rates, customer support tickets).
- Rollback criteria and communication plan.
Evidence & Reporting
Defect summary
Counts by severity, open vs closed, waivers with expiry.

Metric dashboard
Usage analytics, SLA adherence, support tickets, satisfaction surveys.

Case Study Workshop: “Campus Booking App”
Background: University launches a campus facility booking app for students and staff. Teachers can use this step-by-step exercise to walk students through planning validation.
- Understand users: Personas include student, faculty, admin. Identify top tasks (book room, approve request, view schedule).
- Draft validation plan:
- UAT Scenarios – double booking prevention, mobile accessibility, offline notifications.
- Environment – pre-prod with anonymized timetables, role-based accounts.
- Timeline – UAT runs week T-3, pilot with 2 departments week T-2.
- Execute walkthrough: Teacher leads students through scenario “Student reserves lab, faculty approves, admin audits conflict” highlighting expected vs actual output.
- Record findings: Students log 3 sample issues (e.g., conflict message unclear, accessibility gap) and discuss severity.
- Traceability table: Build mini table linking requirements → UAT scenario → pilot metric → defect ID.
Sample Traceability (excerpt)
| Requirement | UAT Scenario | Validation Evidence |
|---|---|---|
| REQ-201 Prevent double booking | Book same room same time | UAT log #15 (Pass), Pilot metric: 0 conflicts in 200 bookings |
| REQ-205 Accessibility compliance | Screen-reader check | Issue VDEF-07 logged, waiver signed with fix date |
Summary & Assignment
Validation proves the product meets user needs in realistic settings. Combining UAT, pilots, and analytics ensures we gather the evidence required for confident releases.
Assignment: Create a validation strategy for your current project. Include personas, scenarios, environments, success metrics, and a traceability snippet similar to the workshop. Present it in class for peer critique.
