laatumääre

Laatumääre is a Finnish term that translates to "quality attribute" or "quality characteristic." It refers to a specific, measurable property that describes the quality of a product, service, or system. These attributes are crucial for defining and evaluating how well something meets its intended purpose and user expectations.

In software development, common laatumääre examples include performance, reliability, usability, security, maintainability, and portability. Performance might be measured by response time or throughput, while reliability could be assessed by mean time between failures. Usability often involves user testing and measuring task completion rates.

Laatumääre are not absolute but are often defined in relation to specific contexts and requirements. For instance, a gaming application might prioritize low latency and high frame rates as critical laatumääre, whereas a financial system would place a greater emphasis on security and accuracy.

Identifying and defining relevant laatumääre early in the development lifecycle is essential for guiding design decisions, setting test criteria, and ultimately ensuring that the final product or service satisfies its stakeholders. They provide a framework for objective assessment and continuous improvement. Without clearly defined laatumääre, it becomes difficult to objectively judge the quality of an offering.
