The questions stated below require answers regarding:
The responses to Questions 1, 2 and 3 are written in the same MS Word document
Question 1
A smartphone provides apps to its user. Apps may be deleted by a user at any time after they have been installed on the phone. Phones have Settings apps (seen as an icon from, for instance, a home screen) from where other apps can be deleted.
Write a scenario for carrying out the deletion of an app via the Settings app.
Question 2
Based upon the scenario you wrote in Question 1, write a use case description for the access and selection of an app via Settings. The user is not deleting an app but is simply going into Settings to locate an app and its associated details. Ensure that all use case fields are included in your answer.
Question 3
During the access and location of an app, as addressed in Question 2, the user is suddenly interrupted by a notification from the phone of the battery being low. The user is therefore informed that the battery is low, and has to deal with this notification before they can continue with what they were doing.
Write a use case description for this situation about a low battery notification.
Question 4
Draw a use case diagram for the two above use cases in Question 2 and 3.
Consider two more situations from Settings: changing to aeroplane mode and turning on wi-fi.
Add use cases for these two situations to the diagram. You are not writing any descriptions for these two situations you are just expanding the diagram with them.
