What is Defect Triage?

Defect triage is the process of reviewing reported bugs and deciding, for each, whether it is valid, how severe and urgent it is, who owns it, and when it should be fixed.

IN DEPTH

In depth.

Borrowed from emergency medicine, triage is about making fast, consistent decisions when there are more issues than capacity to fix them all at once. A defect triage meeting typically brings together QA, development, and product (and sometimes support) to walk the new and reopened bugs and agree on disposition.

For each defect the group confirms it is reproducible and not a duplicate, validates or adjusts the severity, sets a business priority, assigns an owner, and decides the target (this sprint, next, backlog, or won't fix). Good triage depends on good bug reports: a clear title, steps, expected vs actual, and environment let the group decide in seconds instead of debating what the bug even is.

Cadence varies, daily near a release, weekly otherwise. The anti-patterns are triage that rubber-stamps everything as P1 (which makes priority meaningless) and triage with no product representation (which turns urgency into a purely engineering guess).

WHY IT MATTERS

Why interviewers ask about this.

Interviewers ask about triage to see whether you understand the defect lifecycle beyond writing bugs, how teams decide what to fix, balance severity and priority, and keep a backlog sane under pressure.

EXAMPLE

Example scenario.

Before a release, a daily triage with QA, a dev lead, and a PM reviews 20 new bugs in 30 minutes. Well-written reports let them confirm, set priority, and assign in under a minute each; two vague reports get bounced back to QA for steps, which is exactly why report quality matters.

TIP

Interview tip.

Describe who is in the room (QA, dev, product) and what gets decided per bug (valid, severity, priority, owner, target). Mentioning that good bug reports make triage fast shows end-to-end process understanding.

FAQ

Frequently asked questions.

Who attends a defect triage meeting?

Typically QA, a development lead, and a product owner, sometimes joined by support or engineering managers. QA brings the impact view, product brings urgency, and development brings effort and ownership.

How often should triage happen?

It depends on cadence and proximity to a release. Many teams triage daily near a release and weekly otherwise. The goal is to keep the backlog current without turning triage into a time sink.
