John and Rana are working on the initial task analysis, so I'm just posting an example to follow up from the post about use cases. Obviously the tasks at this stage are slightly vague as we don't know all the details about the product yet (e.g. how exactly the user inputs information).
Name: Logging and inputting weight information.
Initiator: User
Goal: User takes a measurement of their weight and stores it in the device, ready for viewing and/or sending to their GP later.
Main Success Scenario:
1. User weighs themselves on a separate device (e.g. scales).
2. User navigates through the device to the section for inputting weight.
3. User inputs their weight.
4. User saves the information.
Possible Issues:
2. User may have difficulty finding the relevant section.
3. User may input the incorrect amount.
3b. User may input the amount in an unexpected format (e.g. lbs, when the device was expecting kg).
4. User may forget to save the information.
