Prestandakriterium

Prestandakriterium is a term used to describe a condition or threshold that defines the required performance of a system, component, or process. It is used to determine whether a product or service meets its performance goals and is typically measurable and testable, often stated as a numerical target or a pass/fail rule.

In practice, prestandakriterier are part of non-functional requirements and are used in design, procurement, testing, and quality assurance. They complement functional requirements by specifying how well the system must perform rather than what it must do. During development, performance criteria guide architectural decisions and influence performance testing, benchmarking, and validation.

Key characteristics include measurability, comparability, and reproducibility. They are established through performance specifications, benchmarks, simulations, or historical data, and are validated through tests. In project management, SLAs and acceptance criteria often embed prestandakriterier, providing a basis for evaluation and contract enforcement.

Examples of prestandakriterier include maintaining a response time under a defined threshold, limiting latency, achieving a minimum throughput, keeping error rates below a specified level, and constraining resource utilization or reliability measures. In fields such as information technology and engineering, setting realistic criteria requires considering expected workload, operating environment, and scalability. Common challenges involve balancing competing targets, ensuring reliable measurement methods, and avoiding overly optimistic or vague targets.
