To ensure that the strategy is working it is important to carry out regular performance monitoring (see Performance monitoring). This will determine whether progress is being made against the action plan and whether objectives are being met.
As well as regular performance monitoring it is important to review the strategy document regularly (see Strategic review), at least annually to ensure that the assumptions on which it is based, and the objectives and mission, are still relevant and appropriate. This review will determine when the strategy needs updating or re-writing. In some cases it may be necessary to re-write the strategy before its end date, due to changes in the economic environment for example.
