Usecase

Case details

End user own geolocation reading on the map

Pre-condition

• Smartphone should be on, with a loaded map into the app
• The geolocation should be stored in the app
• The UI should be on map page

Start

The smartphone does not display anything, the page is blank.

End

The smartphone displays the map with a marker on end user's geolocation

Post-condition

∅

Normal execution

1. Smartphone loads map
2. Smartphone displays map
3. Smartphone loads geolocation from application
4. Smartphone displays end user's geolocation as a marker

Alternative execution

• If map can't be loaded or displayed, redirect to previous page and display an error message
• If geolocation can't be loaded, keep map displayed and display an error message

Non-functional constraint

• Loading should take less than 2 seconds as it is a main feature hence frequently used.
• Map should be readable even in a non urban area (a acceptable default zoom level shall be used).

[Suggestions :]

• Time
• Cost
• Direct environment constraints (physical environment, connections, interfaces, safety, testability, deployment...)
• Indirect environment constraints : PESTLE analysis (Political, Economic, Social, Technological, Environmental, Legal)
