Measure outcomes, not process
This change of emphasis is important for several reasons. First, executives pay attention to what gets measured and what gets rewarded. If leadership development is not enough of a priority for the company to establish goals and track progress against those goals, it will be difficult to make any succession planning process work. Second, the act of engaging with senior executives to establish these goals will build support for succession planning and ownership for leadership development. Third, these results will help guide future efforts and mid-course corrections.
The metrics a company could establish for Succession Development might include goals like the percent of executive level vacancies that are actually filled with an internal promotion vs. an external hire, or the percent of promotions that actually come from the high-potential pool. Too often, companies measure only the percent of managers that had completed succession plans in place.
Keep it simple.
Companies sometimes ad excessively complex assessment criteria to the succession planning process in an effort to improve the quality of the assessment. Some of these criteria are challenging even for behavioral scientists to assess, much less the average line manager. Since the planning process is only a precursor to focus the development, it doesn't need to be perfect. More sophisticated assessments can be built into the development process and administered by a competent coach.
While development plans and succession charts aren't promises, they are often communicated as such and can lead to frustration if they aren't realistic. Bottom line, don't jerk around high performing leaders with unrealistic development expectations. Only give the promise of succession if there is a realistic chance of its happening!
