Lesson 4: Deployment, Operations, Maintenance, and Improvement

This lesson develops practical understanding of deployment, operations, maintenance, and improvement within the Software Development Life Cycle (SDLC) Training. It connects core concepts with realistic testing and quality-engineering decisions.

Learners examine methods, evidence, risks, stakeholder expectations, and implementation considerations before applying the ideas in a focused activity.

Topics Covered

• Release planning, deployment, migration, data conversion, and rollback
• Operational readiness, monitoring, support, backup, and recovery
• Incident, problem, service, change, and release management
• Corrective, adaptive, perfective, and preventive maintenance
• Performance, security, capacity, user feedback, and operations metrics
• Technical debt, modernization, decommissioning, and retention
• Reviews, lessons learned, measures, and lifecycle improvement

Practical Activity

Apply the lesson concepts to a realistic Software Development Life Cycle (SDLC) scenario and document the test approach, evidence, risks, and recommended next actions.

Lesson Outcome

Learners can explain and apply deployment, operations, maintenance, and improvement using structured, risk-aware, and evidence-based testing decisions.
