Scenario

You have been asked to lead a software development team to build a system fulfilling the Statement of Need below. Your team is employed by a small company. The customer wants a project that balances reasonable development cost, timely delivery, software quality, and functionality.

In this project, you will perform preliminary system engineering and create an analysismodel for this system. (See Module 3, Figure 3.1 of the course module commentaries for an overview of the elements of an analysis model). Completing this project will require that you do the following:

• Develop initial notes of the structure/functionality of the system.
• Produce an initial system specification document for the system.
• Develop a detailed scenario based model by writing use cases and develop an activity diagram.
• Create a behavioral model that identifies events with a use case

Completing this project will requirethat you produce a software requirements specification (SRS) document for the system The SRS that you create will be a combination of the System Specification (SS) and the SRS; your SRS must include the essential components of the SS in the SRS.

Your SRS will provide the foundation for Projects 2 through 4, so it must:

• Describe the customer requirements
• Establish the basis for software design
• Be testable, flexible, and traceable.

Statement of Need

John and Jane are starting a bed-and-breakfast (B&B) in a small New England town. They will have three bedrooms for guests. They want a system to manage the reservations and to monitor expenses and profits. When a potential customer calls for a reservation, they will check the calendar, and if there is a vacancy, they will enter the customer name, address, and phone number, dates, agreed upon price, credit card number, and room numbers. Reservations must be guaranteed by 1 day's payment. Reservations will be held without guarantee for an agreed upon time. If not guaranteed by that date, the reservation will be dropped.
