How are acceptance criteria for results defined in a project or task?

Acceptance criteria for the result define when a task or project is considered completed and meets the requirements. They are usually formulated during the planning stage and include:

• Functional requirements: what exactly should work and how.
• Non-functional requirements: performance, security, usability.
• Quality criteria: absence of errors, compliance with standards.
• Test scenarios: successful passing of all tests.
• Documentation: availability of necessary documentation.

For example, for a feature development task, acceptance may include passing unit tests, meeting customer requirements, and QA approval.

Clearly defined criteria help avoid disagreements and ensure transparency in the result verification process.
