Alice wants the system to interface with health and dental insurance companies to obtain the amount remaining in the employee’s account for the year.

Question Two
Mamochachos @ IDM is a small business that caters meals, receptions and banquets for business and social occasions such as manyalo, baby showers and graduation parties. It was inspired by Sethunya’s love of cooking and her talent for preparing fine meals. At first it was a small company with a handful of employees working on small projects. Sethunya met with customers to determine the number of people, the type of meals and other information necessary to cater an event. As their reputation for creating superb food and quality of the service began to blossom, the number of events started to increase. The building of a new convention center along with a prospering business community in the city, increase the number of catering events. Sethunya was able to manage the business using spreadsheets and word processing but found difficulty in keeping up with endless phone calls about what type of meals were available, changes to the number of guest attending the event, and the availability of specialty dietary items, such as vegan, vegetarian, low-fat, lowcarbohydrate and so on. Sethunya’s decision to hire a number of part-time employees to cook and cater the events meant that the complexity of scheduling personnel was becoming overwhelming to the new human resourses manager. Sethunya decided to hire your Consulting company to help her address the problems her catering company was facing.
After performing interviews and observing a number of key staff, the consultants found the following concerns:
1. The master chef ordered supplies (produce, meat, and so on) from suppliers for each event. The suppliers would provide discounts if greater quantities were ordered ata a single time for all events occurring in a given time.
2. Customers often called to change the number of guest for an event with some changes, made only one or two days before the event was scheduled.
3. It was too consuming for Sethunya and her staff to handle each request for catering with about 60 percent of the calls in a contract.
4. Conflicts in employee schedule were occurring and some event were understaffed. Complaints about the timeliness of service were becoming more frequent.
5. Sethunya does not have any summary information about the number of events and types of meals. It would be helpful to have trend information that would help guide her customers in their choice of meals.
6. Events are often held at hotels or other meeting halls, which provide table setting for sit-down meals. There are problems with having sufficient wait staff with the number of guests.
