What Should Be in a Definition of Done?

Start with the job of a Definition of Done

A Definition of Done exists to answer one practical question: is this work complete enough to count as finished? The checklist should protect trust in the increment, not decorate the process with extra seriousness.

That is why a useful Definition of Done is usually shorter than people expect. It only needs the checks that change real delivery decisions.

What a simple Definition of Done usually includes

Most software teams need a small set of checks around implementation quality, testing, review, and anything else the team relies on before it is willing to stand behind the work as finished.

• The agreed functionality is implemented.
• Acceptance criteria are met.
• Relevant tests are completed and passing.
• Review is done if the team expects it.
• The work is integrated cleanly enough to count as part of the increment.

The wording can vary, but the goal stays the same: nobody should have to guess later whether the item really crossed the line.

Keep it grounded in how the team actually ships

A Definition of Done should reflect the team's real quality bar, not a theoretical ideal copied from somewhere else. If the checklist includes steps the team never actually uses, it quickly becomes background noise.

The strongest Definition of Done is the one the team can apply every sprint and still trust under pressure.

Acceptance criteria and Definition of Done are not the same thing

Acceptance criteria describe the expected behavior of a specific backlog item. Definition of Done describes the broader completion standard the team applies across work.

Both matter, but they solve different problems. One clarifies what this item should do. The other clarifies what finished work must include before it counts as done.

Testing, review, and integration belong here for a reason

Many teams discover too late that their idea of done quietly skipped the checks they actually care about. Testing often belongs in the Definition of Done because it protects against the easy slide from built to basically done.

That does not mean the checklist has to describe every test technique. It means the team should be explicit enough that quality does not become negotiable the moment delivery pressure shows up.

Keep the template light enough to use every day

If the Definition of Done grows into a giant document, people stop using it as a decision tool and start treating it like a formality. The best version is short enough to remember and real enough to affect choices during development, review, and release pressure.

A useful standard should guide work, not just decorate a wiki.

What usually goes wrong

• The Definition of Done is too vague to settle arguments.
• The checklist is so heavy that nobody can apply it consistently.
• The standard is frozen even after the team's quality needs change.
• The checklist exists somewhere, but never shows up in real sprint decisions.

TL;DR

• A Definition of Done should answer whether work is truly finished, not just mostly built.
• A useful version usually includes implementation, acceptance criteria, testing, review, and clean integration.
• Acceptance criteria describe item behavior; Definition of Done describes the broader completion standard.
• The checklist should be light enough to use every day and strong enough to matter under pressure.
• A strong Definition of Done stays short, real, and specific enough that the team can still trust it when delivery pressure shows up.
