ISTQB_Managing the Product_2.3 Defect Management_TM-2.3.2 (K2) Explain the process and participants required for effective defect management

 

Concept	Explanation
Ownership	Test Manager typically owns the overall defect management process and tool.
Cross-functional Team	Defect Management Committee includes test manager, developers, product owner, PM, suppliers, etc.
Defect Lifecycle Decisions	Committee decides if a defect is valid, should be fixed, deferred, or rejected.
Triage Meeting	Regular meeting to assess, prioritize, and assign defects based on impact, risk, and cost.
Priority Setting	Based on risk, benefit, effort; input from test team ensures objectivity.
Defect Manager Role	May be needed in large projects to manage tool, prep meetings, and follow-ups.
Effective Communication	Tools and committees should support communication, not replace it.
Tool & Workflow	Tool support, structured workflow, and clear responsibilities improve efficiency.

Area	Description	Example
Committee Composition	Test Manager + Dev + PM + Product Owner + Supplier	A product under test has modules built by in-house and outsourced teams.
Defect Evaluation	Check if defect is valid and worth fixing	Defect logged by tester: UI button misaligned on mobile screen. Committee validates and sets it as "Low" priority.
Triage Discussion Points	Risk, cost, benefit, priority	Fixing a minor cosmetic issue may be deferred to next release.
Defect Assignment	To relevant party	Backend issue found — assigned to API team, not frontend.
Defect Manager	Optional but useful in large projects	One full-time person tracks >300 weekly defects in enterprise ERP testing.
