scenario :

Availability of transportation at the right time and place with safety and economy is one of the biggest concerns in large cities of Pakistan. Most of the people belong to either middle or lower-middle-class families who need rides on daily basis to go to their workplace and cant afford car services. Considering this situation suppose you as an entrepreneur, come up with the idea of building an app for on-demand bike service with cheapest rates, GPS tracking and licensed drivers to provide safety security and economy for the general public. Since many of the people in Pakistan are not familiar with English so you decide to provide instructions and UI in both Urdu and English. The user just needs to install the app. Turn on his location. Choose the pickup point and drop off point for the ride and the app will tell the user the estimated fare. Once the user confirms the ride he can track his journey and share his location with friends for safety purpose. Once he reaches the destination the app will notify the user that he has reached his destination and will ask for payment and after giving the payment app will again notify that payment process has been successfully completed and the ride ends.

a. For the system given above, you are required to make a system sequence diagram.

b. Make operation contracts for select drop off location and end ride.

c. What are some of the risk factors(identify at least 5 risks) that you could identify in this case. Provide risk mitigation strategies for all of them.
