PROGRAM DEVELOPMENT LIFE CYCLE

The process of coming out with the basic steps to implement a procedure in computer programming.

(a)  

This phase of programming cycle is when the requirements will be determined like variables, functions, data types etc.

• Coding

• Maintenance

• Problem analysis

• Problem Identification

These two are considered as design development tools in programming.

• Flowchart

• code chart

• algorithmic language

• Structure chart

It is in this phase where the development of a step-by-step procedure to solve the problem using the specification given in the previous phase.

(a)  

The problem statement is defined, and the boundaries of the problem are decided upon. What phase is this?

• Problem Identification

• Problem Analysis

• Problem Focus

• Problem determination

It is the blueprint of a program.

• Pseudocode

• Structure chart

• Flowchart

• Algorithm

Expressed in program language like constructs, this tool describes the way to arrive at a solution.

(a)  

In the monitoring phase, the 3 following actions must be considered;

• enhancements additions

• active usage

• evaluation

• desk checking

It is the actual process of writing program instructions.

(a)  

This is the beta phase of a program where the error checking also known as desk checking is performed.

• Desk Checking

• Testing and Debugging

• Deskchecking and Testing

• Error and Data check
