Document Summary
A program is a list of instructions for the computer to follow to accomplish the task of processing data into information. A program is a list of instructions for the computer to follow a process data. This phase focuses on formalizing the written description and processes used in the program: program maintenance: completed programs are periodically reviewed to evaluate their accuracy, efficiency, standardization, and ease of use. Changes are made to the program"s code as needed. Software engineers or programmers use this six-step procedure: program specification, program specification is also called program definition or program analysis. It requires that the programmer-or you, the end user, if you are following this procedure- specify five items: (1) the program"s objectives, (2) the desired output, (3) the input data required, (4) the processing requirements, and (5) the documentation. It is best always to specify outputs before inputs. That is, you need to list what you want to get out of the computer system.
