Acceptance Criteria
Acceptance criteria are the specific conditions that a deliverable must satisfy for the client to consider it complete and approved. They serve as an objective standard for evaluating project outputs, removing subjectivity from the approval process. In a proposal or statement of work, acceptance criteria are defined for each deliverable and describe measurable requirements such as functionality, performance benchmarks, design specifications, or compliance standards. For example, acceptance criteria for a website might specify that all pages load in under three seconds, pass WCAG 2.1 AA accessibility checks, and render correctly on the three most recent versions of major browsers. When acceptance criteria are met, the client formally accepts the deliverable, which typically triggers the corresponding milestone payment. Without clearly defined acceptance criteria, projects risk indefinite revision cycles because neither party has an agreed-upon definition of done. Acceptance criteria also protect the service provider by establishing that approval is based on objective standards, not shifting preferences. They are a foundational element of professional project management.
Example
A design agency specifies in its SOW that the logo deliverable will be accepted when the client receives vector files in SVG and EPS formats, a color palette with hex and Pantone values, and usage guidelines in PDF format.
Frequently asked questions
- Who defines acceptance criteria?
- Acceptance criteria are typically proposed by the service provider and agreed upon by the client before work begins. Both parties should review and negotiate the criteria during the contracting phase. This collaborative approach ensures the criteria are realistic, measurable, and aligned with the client's actual needs.
- What happens if a deliverable does not meet the acceptance criteria?
- The client can request revisions within the process defined in the contract, which usually specifies a limited number of revision rounds. If the deliverable still fails to meet the criteria after revisions, the contract's dispute resolution clause governs the next steps, which may include mediation or termination.
- How specific should acceptance criteria be?
- Specific enough to be testable. Vague criteria like "high quality" or "professional look" invite disagreement. Instead, use measurable standards such as page load time thresholds, resolution requirements, or feature checklists. The more objective the criteria, the smoother the approval process.
