Stages of system development life cycle

In this tutorial, you will learn about, different stages of the system development life cycle.

System development lifecycle specifies seven steps:

  1. Preliminary investigation: It is also called primary investigation. In this stage, we can determine or recognize the real problem of the existing system and also investigate the problem region and gather information required for design new software.
  2. Analysis of requirement: In this stage requirement analysis specifies all possible task performed by software. Analysis of requirement performed by system analyst where system analyst has various skills like:
          1. Sharp mind.
          2. Skill for project management.
          3. Gather full information but understand in Broadway.
          4. Knowledge of various computer language system and technology.
  3. System design: It is also performed by system analyst where system design depends on all requirements gather during analysis of requirement system design specified by using DFD, ER model, Pseudocode, Algorithm, etc.
  4. System coding: System testing allows to execute specified code and run according to all given values and specifies all possible thread. System testing also done by programmer.
  5. System implementation: System implementation is the most vital page of SDLC. In this phase, we can install the current project and current software and provide training for the user.
  6. System testing: System testing allows to execute specified code and run according to all given values and specifies all possible thread.System testing also done by programmer.
  7. Maintenance: System maintenance allow to improve the system when needed. This is the last stage of the SDLC in which we can remove all defects and update when required.
