Quality Engineering Should Begin Before Testing
Testing cannot fully compensate for unclear requirements, weak design decisions, or inconsistent delivery practices. Quality should be built into the initiative from discovery through production operations.
Quality is often treated as the final stage before release.
The development team completes the solution, testing begins, defects are identified, and delivery is delayed while issues are corrected.
This approach places too much responsibility on testing and too little emphasis on preventing problems earlier.
Quality engineering should begin before the first test case is written.
During Discovery
Business objectives, user needs, requirements, constraints, and acceptance criteria should be clear enough to support consistent design and delivery.
During Design
Architectural decisions should consider performance, security, integration, resilience, operability, and future change.
During Development
Automated checks, code reviews, integration validation, and continuous testing should identify issues while they are still inexpensive to correct.
During Testing
Functional, regression, performance, security, and user acceptance testing should validate both technical behavior and intended business outcomes.
During Operations
Monitoring, incidents, user feedback, support trends, and production performance should inform continual improvement.
Key Takeaway
The purpose of quality engineering is not to find as many defects as possible.
It is to create a delivery environment in which fewer defects are introduced, important risks are identified early, and releases become more predictable.
