Program Development
The program development cycle for the Reservations program consists of tasks
that correspond to the six development cycle phases, as shown in Table 5-1.

Table 5-1 Reservations Program Development Tasks
DEVELOPMENT PHASE TASK(S)

1 Analyze the requirements Analyze the Reservations problem.

2 Design the solution Design the user interface for the application,

including the layout, data, and components.
Design the logic to solve the problem.

3 Validate the design Confirm with the user that the design solves the

problem in a satisfactory manner.

4 Implement the design Translate the design into code. Include internal

documentation (comments and remarks) within
the code that explains the purpose of the code
statements.

5 Test the solution Test the program. Find and correct any errors

(debug) until it is error-free.

6 Document the solution Print copies of the program code and interface.

Analysis and Design

Figure 5-2 on the next page shows the requirements document that initiates
the development cycle for the Reservations program. The requirements docu-
ment specifies the reason for the request, lists the required inputs and outputs,
references the need to set the room status back to available each morning, and
notes the need for possible changes to the program to support additional rooms.
