Definition of Done – Definition, Use Cases and Best Practices at a Glance
The Definition of Done binds when a task, feature or sprint result is considered truly finished. Beyond programming it covers code review, tests, documentation, security and business sign-off.
Definition of Done: Definition & Benefits | Glossary
"Done" is a dangerous word in software projects. For one person it means "coded", for another "tested, documented and signed off". This is exactly where the Definition of Done comes in: it turns a fuzzy feeling into a binding, shared understanding.
Only when all agreed criteria are met is a task considered finished – creating transparency, reliable sign-offs and maintainable software.
This glossary entry for Definition of Done gives you a clear Definition, practical Use Cases and Best Practices at a glance – with examples, pros and cons, and FAQs.
What is Definition of Done?
- Definition of Done – The Definition of Done binds when a task, feature or sprint result is considered truly finished. Beyond programming it covers code review, tests, documentation, security and business sign-off.
The Definition of Done (DoD) is a binding, jointly agreed set of criteria that defines when a task, user story or sprint result is truly complete. It is a central element of agile development and especially of Scrum.
"Coded" is not enough: a good Definition of Done typically covers code review, automated tests, fulfilled acceptance criteria, up-to-date documentation, passed security checks, deployability, a successful test on a staging environment, and business sign-off. The DoD applies uniformly to all tasks, creating comparability and transparency.
It differs from a single story's acceptance criteria: acceptance criteria describe what a specific function must do; the DoD describes the overarching quality requirements for every delivery.
How does Definition of Done work?
The team agrees the Definition of Done jointly – ideally with development, quality assurance and business involved. It defines which steps a task must pass before it counts as done: code review, automated tests, documentation, security checks and business sign-off.
These criteria are made visible, for example on the board or in the ticket system. During a sprint, each task is measured against this DoD; if even one criterion is open, it is not done.
In regular retrospectives the team checks whether the Definition of Done still fits – too strict slows small changes, too vague prevents real steering. This way the DoD evolves with the project.
Practical Examples
A story is only done once the code is reviewed, automatically tested, documented and signed off by the business.
A team adds a security check to its Definition of Done after a vulnerability was noticed too late.
Before each release, the DoD ensures all features have been tested on a staging environment.
A business unit sees on the board that a task is not yet released despite finished coding because sign-off is missing.
On a vendor change, a clear DoD ensures new deliveries meet the same quality standard.
Typical Use Cases
Agile software projects using Scrum or Kanban
Distributed teams that need a shared quality understanding
Projects with business sign-off and regulatory requirements
Collaboration with external vendors and clear delivery standards
Products with high demands on maintainability and security
Teams that want to solve recurring quality problems structurally
Advantages and Disadvantages
Advantages
- A shared, binding understanding of "done" across the whole team
- Transparent sign-offs instead of debates about completion level
- Higher code quality and maintainability through embedded tests and reviews
- Less rework because quality is not only checked at the end
- Reliable release readiness because every delivery meets the same standard
Disadvantages
- A too-strict definition can needlessly slow small changes
- A too-vague definition prevents real steering and comparability
- Requires discipline to follow the criteria consistently
- Must be reviewed regularly and adapted to the project
- Only works if the whole team accepts and lives the DoD
Frequently Asked Questions about Definition of Done
What is the difference between Definition of Done and acceptance criteria?
Acceptance criteria describe what a specific function must do. The Definition of Done describes the overarching quality requirements that apply to every delivery – such as tests, review, documentation and sign-off.
What typically goes into a Definition of Done?
Common elements are code review, automated tests, fulfilled acceptance criteria, up-to-date documentation, security checks, deployability, a test on staging and business sign-off.
Who defines the Definition of Done?
The team agrees it jointly, ideally with development, quality assurance and business. This creates an accepted, realistic quality understanding instead of an externally imposed rule.
How strict should the Definition of Done be?
As strict as necessary, as lean as possible. Too-strict criteria slow small changes, too-vague ones prevent steering. The DoD should be reviewed regularly in retrospectives.
Does the Definition of Done apply to every task?
Yes, it applies uniformly to all tasks, creating comparability. Special cases may have additional criteria, but the shared core stays the same for everyone.

Look beyond isolated technical merits
When you judge whether Definition of Done is the right fit, look beyond isolated technical merits. You should weigh the full project context.
Consider the following factors:
- Existing team expertise
- Current infrastructure
- Long-term maintainability
- Total cost of ownership (TCO)
