suorituskuvaukset

Suorituskuvaukset, often translated as performance descriptions or performance statements, are a key concept in software engineering and systems analysis. They describe the non-functional requirements of a system, focusing on how well a system performs a given function. Unlike functional requirements, which specify what a system should do, suorituskuvaukset detail the quality attributes of that functionality.

These descriptions typically address aspects such as response time, throughput, resource utilization, and scalability. For example, a suorituskuvaus for a web application might specify that the homepage must load within two seconds under normal load conditions and handle up to 100 concurrent users without performance degradation. Similarly, a suorituskuvaus for a database might define the maximum time allowed for a specific query to return results.

The purpose of suorituskuvaukset is to provide measurable and verifiable criteria for evaluating a system's performance. They help developers understand the performance expectations and enable testers to create relevant performance tests. Clear and well-defined suorituskuvaukset are essential for ensuring that a system meets user expectations and business needs, especially in performance-critical applications. They contribute significantly to the overall quality and usability of a software product.
