kitchen and bathroom remodels and want a system that can do the following:
1. Maintain information on homeowners (location, date and time of appointment, overall requirements including time scale)
2. Maintain an inventory of products (sinks, dish washers, etc) that can be used in the estimation process (size, features, cost, price etc);
3. Allow the homeowner to select these products as the company visits the site and does the rough design;
4. Allow for the input of all measurements as the company representative examines the site;
5. Allow for the entry of photographs from the current site for specific problem areas
6. Calculate a estimate range for the work that requires to be done in the time frame specified
7. Prepare a printed report for the homeowner that provides all the details behind the estimate
Questions for this scenario:

2. Prepare a use case diagram for the entire application
3. Prepare a use case for one requirement, either 2, 4, or 6
4. Prepare a class diagram for the inventory component (2) including all attributes and methods
5. Prepare a priority model based on the following:
• Total cost is $200,000
• Total value is $400,000
– 1: 5% of value and 10% of cost, benefit 2, penalty 1
– 2: 15% of value and 10% of cost, benefit 7, penalty 1
– 3. 15% of value and 20% of cost, benefit 8, penalty 2
– 4. 15% of value and 10% of cost, benefit 6, penalty 4
– 5. 10% of value and 5% of cost , benefit 5, penalty 6
– 6. 30% of value and 40% of cost , benefit 9, penalty 9
