QUALITY THROUGHOUT

Testing is a loop through the whole project

Start with a checkable promise. Every correction returns to the failed check and to the behavior it could have affected.

01

Before code

Check the need, scope, rule, and expected outcome.

02

During each change

Review the change. Check the component and its connections.

03

Before live use

Exercise the full journey, access restrictions, workload, and operating response.

04

After opening

Observe the service. Investigate failures and use them to improve the next version.

THREE DIFFERENT DECISIONS

A passed test is one piece of the evidence.

01

Works in a check

The identified version met the stated criterion.

02

Accepted for its scope

The Client accepted the agreed software outcome.

03

Ready to open

Live-use protection, coverage, and operating procedures are ready.

Keep the feedback loop open. A pilot can reveal a misunderstood task. Operation can reveal a missing alert. Return to the affected rule, design, implementation, and checks.
