Discuss what quality attributes would a project manager consider important for the software system described below.

The requirements below partially describe a software that is aimed at providing an online dog minding service. The application allows booking a service with a dog minder, communication with the dog minder and real time tracking of dog walks (these requirements are omitted in this question). Draw a UML class diagram describing an object-oriented system using the list of requirements below. 1. The system has two types of users: owner and dog minder. 2. An owner has many dogs. 3. An owner has many addresses. 4. An owner can make a booking with a dog minder. 5. Each booking is for a dog, owner and dog miner. 6. An owner can have up to three bookings. 7. A dog minder can have many bookings. 8. Each booking is for a single service. 9. The system provides two types of services: dog walk and day care. 10. Each service has a description. 11. Each booking has a payment. 12. The system must allow unpaid bookings. 13. Each payment is made by an owner. 14. The system accepts two types of payments: paypal and (credit) card. 15. All users are kept in the system registry. HINTS: RQ2 and RQ3: The system must guarantee the removal of the dogs and addresses of an owner when the owner is removed from the system. RQ2 and RQ3: Does it makes sense to have an owner in the system without a dog or an address. RQ5: The system should allow dogs without booking. RQ8: The system assigns a separate service object to each booking (design decision). The same type of services has the exact same description. Please use the names below for the class names in your diagram: User, Owner, DogMinder, Address, Dog, Booking, Service, DogWalk, DayCare, Service Description, Payment, Paypal, Card, Registry
