Carefully read the case study below (Alpha Shuttle) and attempt the questions that follow.

Alpha Shuttle is an independent taxi company operating in a major city. Alpha Shuttle owns taxis which it rents out to drivers on an annual basis. Each vehicle is effectively rented out to three drivers to cover three 8 hour shifts in a day. Alpha Shuttle is a profitable company because it has built up a good reputation locally, and there is always a waiting list of drivers wanting to apply to rent a vehicle. Alpha Shuttle expands gradually by purchasing new vehicles from local car dealers. Each driver pays an annual rental fee in advance to Alpha Shuttle in return for use of a vehicle for 8 hours a day every day of the year. In addition to the annual rental, Alpha Shuttle takes 5% of the money a driver earns every week. Alpha Shuttle is responsible for taxing, insuring and maintaining the vehicles. If a vehicle is due for a service or needs to be repaired, Alpha Shuttle contacts a garage and arranges it. Alpha Shuttle keeps records of the repairs and services for each vehicle, and records of the corresponding garages. At the end of each shift, drivers give the money they have earned to Alpha Shuttle. If they needed to refuel the vehicle, they also submit an expense claim at the end of the shift.

At the end of every week, Alpha Shuttle calculates the amount owed to each driver based on the money earned from fares, the expense claims and the deduction of 5%. The drivers are then paid.

NOTE: According to the owner of Alpha Shuttle, all the above activities are handled manually.

Question 1

With reference to the Alpha Shuttle case study, produce a system Use Case Diagram.

Question 2

As a Software Engineer employed by Alpha Shuttle, you study a proposal for a new system that will completely automate the work at Alpha Shuttle. You discover that the cost of developing the system would be far more than the cost of continuing to do the work manually, so you recommend against proceeding with the project.

How do you think each of the stakeholders described in Task 1 would react to the situation?

Question 3

As a Software Engineer employed by Alpha Shuttle, you implement a system according to the precise specifications of the Alpha Shuttle owner. However, when the software is put into use, the users find it does not solve their problem.

How do you think each of the stakeholders described in Task 1 would react to the situation?

Question 4

For the system, which attributes of quality do you think would be the most important and the least important and why?

Question 5

After determining functional requirements from the scenario, draw the interface of this application. Pay attention to the layout; specify all labels you would use; propose icons or other encoding techniques to make your interface more usable.
