   Like all process the software development process
    follows a cycle comprised of the following four
   Plan(P): Device a plan.Define your objective and
    determine the strategy and supporting methods
    required to achieve that objective.
   Do(D): Executive the plan. Create the conditions
    and perform the necessary training to execute the

   Check (C): Check the results. Check to determine
    whether work is progressing according to the plan
    and whether the results are obtained.
   Action (A): Take the necessary action. If your
    checkup reveals that the work is not being
    performed according to plan or that results are not
    what was anticipated device           measures for
    appropriate action.
