Now it might happen that a review of all of these factors may not turn up anything out of order; everything seems to have been scrapped according to plan. If that is the case, then the manager must be back to the plan and question whether the plan was what it should have been. Then the next step–that of replanning–follows. If the performance did not even approach achievement of the expected results, then the original plan might be done and new plan drawn up. Usually this is not the case. In most instances the original plan needs only to turn modified; only a degree of replanning is called for (Dejon, 1978, p. 145).
