Phases in the Programming Task

Problem Solving Phase

• Analysis and Specification

  Understand (define) the problem and what the solution must do

  
  

• Algorithm Development

  Develop a comprehensive unambiguous logical sequence of steps to solve the problem

  
  

• Verification of Algorithm

  Follow steps closely (manually) to see if solution works

  
  

Implementation Phase

• Program Development

  Translate algorithm into a program written in a programming language

  
  

• Program Testing

  Test program for syntactical and logical errors. Fix the errors.

  
  

Maintenance Phase

• Use

  Use the program to solve real world problems

  
  

• Maintain

  Modify the program to meet changing requirements
