Chapter 11, Problem 1Q

Program Plan Intro

To list and describe the main tasks that are performed during implementation of the system.

Program Description Answer

Following are the tasks that are performed during system implementation:

• Application development.
• Testing.
• Documentation.
• Training.
• Data conversion.
• System changeover.
• Post -implementation evaluation.

Explanation of Solution

During the system implementation, some tasks are performed by the programmer. The tasks are given below:

• Application development.
• Testing.
• Documentation.
• Training.
• Data conversion.
• System changeover.
• Post -implementation evaluation.

Application development:

In the application development, the basic tasks are performed. In this field, program structure and modules are prepared for the program, coding and the basic structures are created.

Testing:

In the testing part, each program module or units are tested by the testing team. The team will ensure that the program is working properly. CASE tools are used for testing of syntax errors.

Documentation:

After developing the successful software a proper documentation is required. In the documentation part, every single detail is documented starting from the system analysis phase to system implementation phase. It also helps in maintenance of the project. It also describes the inputs, outputs and logic of the program modules. A proper documentation helps the IT staff, users and managers who interact with the system.

Training:

To run the system successfully, a proper training for IT staff, users and managers is required. If the people do not understand the system, then it results in a failure. Proper training must be given to the end users to understand the system and to know how to interact with the system.

Data conversion:

Data conversion is a process which helps in loading the existing data into the new system.

System changeover:

System changeover is process which switches the new information system over the old information system. This process can be done slowly or fast depending upon the system.

Post -implementation evaluation:

In this section an evaluation is done on the overall quality of the information system after implementation of the program. It also checks how the program is working after implementation.
