Normally, those responsible and accountable for a strategy know whether it is producing the desired results. It is not enough to know whether the plan is working effectively or has failed to produce the desired results. Simply assuming the strategy worked because the targets are being achieved may overlook the potential that the success was attributable to other factors or that greater success could have been achieved. If the success was the result of other factors, it is important to identify and capitalize on these attributes. If the strategy failed to achieve the targeted objectives it is equally important to understand the weaknesses in order to make adjustments.
