2. Use case modelling: user goal technique You have been asked to carry out use case modelling to identify the functional requirements for a new fitness watch targeted at swimmers, similar to those produced by Garmin or Polar. The target user is anyone from a recreational to a competitive swimmer, and both open water and swimming pool laps are to be catered for. The watch is to connect with an app that will provide a variety of additional features as well as those on the watch itself. Use the user goal technique to identify all the use cases that would be relevant to a swimmer who would be a potential user of the watch. Use your own experience, or that of a swimmer of your acquaintance, together with any research you need to do.
