Time-on-Task or Task Completion Time is a metric that measures the amount of time it takes for a user to complete a specific task or set of tasks on a website or application. It is commonly used to measure the efficiency and usability of a website or application, as well as user engagement and satisfaction. A shorter time-on-task generally indicates that a website or application is easy to use and navigate, while a longer time-on-task may indicate that users are struggling to complete certain tasks and may need to be redesigned or improved.
The formula for calculating time-on-task is:
Task completion time = (Total time spent on task / Number of successful task completions)
- “Total time spent on task” is the total amount of time users spend on the task or set of tasks.
- “Number of successful task completions” is the number of times users successfully completed the task or set of tasks.
For example, if users spent a total of 1000 minutes on a task and successfully completed it 80 times, the average task completion time would be 12.5 minutes.
It’s important to note that time-on-task can be measured for different types of tasks such as registration, purchase, search, etc. It’s also possible to segment the data by different user characteristics like demographics, device, location, etc. This way, you can get a better understanding of which user groups are taking more time to complete the task and where improvements need to be made.
