Stages of Program Development Process

It is the most important problem solving technique. A programmer follows these stages to develop a computer program.

1. Defining and Analyzing Problem

2 Designing the Algorithm

3 Coding or Writing the Program

4 Testing and debugging

5. Final Documentation

7 Maintenance

Defining and Analyzing the Problem

In this step, a programmer studies the problem. He decides the better method to resolve the problem. Studying a problem is a must because it helps a programmer to decide about the following things.

• The facts and figures are essential for making the software.
• The way in which they will be designed.
• Selection of the language in which the writing program is more convenient.
• What is the required result and in which form it is required, etc.

Designing the Algorithm

A programmer must follow a set of instructions known as an algorithm before they can begin creating their program. An algorithm is created by the programmer to assist in visualizing potential software alternatives.

Coding or Writing the Program

Coding is the most important step in developing a program. The programmers convert the algorithm into the coding form. There are different types of programming languages that are used to write a program. The programmer selects the language according to the program requirement.

Testing Program

Throughout the development process, programs must be tested. This procedure checks a program’s correctness. By running the program repeatedly, the program is tested. The output is examined after various input values are provided.

If the program has any errors, it might not produce the desired outcomes. If the output is incorrect, the errors must be found and fixed. During programming, all bugs are found and eliminated. It guarantees that the program produces the expected results and that the issue is resolved properly.

Final Documentation

When the program is finalized, its documentation is prepared which helps the user how to use the software in an efficient way. The other purpose of documentation is to modify the code by other programmers if it is necessary. Documentation should be done at each step during the development of a program.

Maintenance and upgrading

In this step, the program has enhanced the program according to the user’s choice. If the user wants some enhancement in the program. The programmer follows all phases to enhance the program. The programmer upgrades the program with time to enhance its features.

Program development is the most important process of solving the problem.
