HKSM

A defined condition or capability used to verify that a result's quality attributes are acceptable and conform to agreed standards.

Key Points

• Specifies measurable criteria or standards for quality attributes such as performance, reliability, security, or usability.
• Guides quality planning, assurance, and control by stating what acceptable quality looks like.
• Often expressed as metrics, thresholds, tolerances, tests, or acceptance criteria.
• Is traceable to stakeholder needs and verified through inspection, testing, or analysis.

Example

A web service must return responses within 2 seconds for at least 95% of requests under a load of 500 concurrent users. During system testing, this requirement is measured to decide if the deliverable meets the project's performance quality expectations.
