Tehtäväsaanto

Tehtäväsaanto, often translated as "task success rate" or "task completion rate," is a metric used to evaluate the effectiveness of a system, process, or user interface. It quantifies the proportion of users who successfully achieve a specific goal or complete a predefined task. This metric is commonly employed in areas such as user experience (UX) research, software development, and process improvement.

Calculating tehtäväsaanto typically involves observing users as they interact with a system or process. A task is considered successful if the user reaches the intended outcome without significant errors or requiring external assistance. The formula for tehtäväsaanto is the number of successful task completions divided by the total number of attempts, expressed as a percentage. For example, if 80 out of 100 users successfully complete a specific task, the tehtäväsaanto is 80%.

High tehtäväsaanto generally indicates a well-designed and efficient system or process. Conversely, a low tehtäväsaanto suggests potential usability issues, design flaws, or inefficiencies that hinder users from achieving their objectives. Analyzing the reasons behind task failures is crucial for identifying areas that require improvement. This can involve qualitative data such as user feedback and observation, alongside quantitative data.

Tehtäväsaanto is a valuable metric for benchmarking performance, identifying pain points, and guiding iterative design and development efforts. It provides a clear and measurable indication of how well a system or process is meeting the needs of its users.
