The implementing and sustaining plan is about how you can assemble the plan from different levels, initiate the plan, and provide sustaining activities. The implementing and sustaining phases must work together in a seamless flow to ensure execution of the plan. The implementation period is characterized by quarterly reviews. A full review and update of the plan is conducted in the fourth quarter. Your plan should be monitored frequently to make sure it is being implemented in the spirit and intent of the planning conference.
Some businesses in certain situations elect to monitor their progress or success on a weekly basis. This is probably appropriate for operational levels in an organization. For example, in a manufacturing environment you may choose to monitor daily and formally report weekly. Some organizations choose to report on a monthly basis. Tracking sales monthly is a common example. The minimum length of time allowed without formally checking your plan is a quarter. Reporting results on a quarterly basis is the most accepted business practice for performance measures. The framework is consistent with financial reporting, shareholder expectations, and public acceptance.
While the first, second, and third point are the performance review, the fourth point of monitoring your plan is the annual report. At the end of the fourth quarter you need to look back at the four quarters collectively. The past year is compared with the previous year and projected out to the ten-year plan. This gives you a baseline to begin planning for the next year or repeating the one-year operational plan. The results are published in the annual report.
