Software Development Cycle

Syllabus Detail

  • Stages (5) of the software development cycle. 11 GEN, 11 ATAR, 12 GEN

 

Background

  • The software development cycle fits within the system development life cycle, specifically within the development phase.

State the Problem

  • Be clear on what is needed and who will be using the program.
  • Be very clear on what the program must do and how it will be used. 

Plan and Design

  • Plan the program with IPOs, flowcharts and/or pseudocode
  • Determine inputs, processing, outputs (IPO eg)
  • eg What inputs are needed?, What processes will happen? What outputs are needed?
  • Make flowcharts, and/or algorithms and/or pseudocode.
  • Control structures; sequence, selection and loops are considered and used as wanted.

Develop

  • Code the program.
  • Use the pseudocode and a programming language of your choice.

Test

  • Test (debug) the program to make sure it works as it is supposed to.

Evaluate

  • The program is evaluated to see if it does what it was designed to do.
  • When the program needs a software update, an improved version can be distributed.
