How much time should be allocated to QA?

Allocate 20-30% of development effort to QA activities including writing tests, manual testing, code reviews, and UAT coordination. For mission-critical systems, this may be higher. The investment pays for itself in reduced defects and rework.

Do we need a dedicated QA team?

Not necessarily in Agile teams where quality is a shared responsibility. Developers write tests, team members conduct reviews, and the PO verifies acceptance criteria. Dedicated QA adds value for complex systems, performance testing, and security testing.

What is the cost of poor quality?

Defects found in production cost 10-100x more to fix than those caught during development. Beyond direct costs, poor quality leads to customer dissatisfaction, lost revenue, and team morale issues. Proactive QA is one of the highest-ROI investments in any project.

Quality Assurance (QA)

Quality Assurance

The systematic process of ensuring deliverables meet defined quality standards through planned activities, testing, and reviews throughout the project lifecycle.

In-Depth Explanation

Quality Assurance is the proactive process of defining quality standards and building checks into the delivery process to prevent defects rather than catching them afterward.

QA vs QC:

Quality Assurance (QA): Process-focused, preventive - ensuring right processes are followed
Quality Control (QC): Product-focused, detective - testing and inspecting deliverables

Types of testing:

Unit testing: Testing individual components in isolation
Integration testing: Testing how components work together
System testing: Testing the complete system end-to-end
User acceptance testing (UAT): Business users verifying requirements are met
Performance testing: Verifying system performance under load
Regression testing: Ensuring changes do not break existing functionality

QA best practices:

Define quality standards before development begins
Implement automated testing for repeatable checks
Include QA in the Definition of Done
Test early and continuously
Use peer reviews as quality gates
Track defect metrics to identify patterns
Involve end users in UAT before deployment

QA in Agile:

Testing happens within each sprint
The whole team owns quality
Automated tests enable continuous integration
Acceptance criteria drive test creation
Definition of Done includes quality requirements

Business Context

Effective QA reduces defect costs by catching problems early, preventing rework, customer dissatisfaction, and reputational damage that far exceeds the cost of prevention.

How Clever Ops Uses This

Clever Ops builds quality assurance into every delivery phase for Australian clients. We use automated testing, peer code reviews, and structured UAT to ensure automations and integrations work correctly before going live.

Example Use Case

"A team implements automated regression testing for their CRM integration, running 200 test cases in 15 minutes after every code change, catching a critical data mapping error before production."
