When developing metrics to assess if implementation is proceeding effectively managers may be faced with the challenges of first impressions vs. sustained performance, subjectivity vs. objectivity, and/or uncertainty of what metrics actually accurately reflect implementation effectiveness. Regarding first impressions vs sustained performance, milestones and targets should accompany strategy implementation. The timeline should permit opportunity for implementation to return results and that timeline or expectation should be realistic. Alternatively, the measure of effectiveness should include sustained delivery as opposed to only immediate delivery. Subjectivity should be minimalized. Metrics that can objectively be measured and evaluated more accurately evaluate the effectiveness of implementation vs those that are based on opinion or judgment. As opinions are personal, any measure of effectiveness based on opinion or judgment includes bias and should not be considered as a true evaluation. Also, managers can be faced with the challenge of uncertainty regarding how best to measure effectiveness of implementation. If the strategy is one with a financial objective, cost savings, return on investment or other financial considerations should be evaluated. If the strategy is strategic in objective, metrics should focus around desired performance outcomes
