How do you write programs

In developing a computer program the programmer must:

                    Analysis - Understand/Define the problem 

                    Design – plan the solution

                    Implement - Write/Code the program

                    Test - Compile, Debug & Test 

                    Release - Implement the program 

                    Maintain - Document the program

The software development lifecycle (SDLC) is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The goal of SDLC is to minimize project risks through forward planning so that software meets customer expectations during production and beyond.
