How do you measure task effectiveness?
Effectiveness can be calculated by measuring the completion rate. Referred to as the fundamental usability metric, the completion rate is calculated by assigning a binary value of '1' if the test participant manages to complete a task and '0' if he/she does not.
What is measurement of task completion?
The Fundamental Usability Metric
After testing all your users, the average of all those 1's and 0's gets you the task completion rate. For example, if 9 out of 10 users complete a task, the completion rate is . 90 or 90% when expressed as a percentage.
How will a task be measured?
Task success rate is calculated based on the average of all users (in a given time period) for all tasks. For example, if you measure tasks success for tasks A, B, and C and the rates are 70%, 80%, and 100%, respectively, then the overall task success rate is 83% (70+80+100)/3.
What is task completion rate?
You report completion rates on a task by dividing the number of users who successfully complete the task by the total number who attempted it. For example, if eight out of ten users complete a task successfully, the completion rate is 0.8 and usually reported as 80%.
