This chapter discusses strategy evaluation, review, and control. It outlines several frameworks for evaluating strategy, including Rummelt's four criteria of consonance, consistency, feasibility, and advantage. It also discusses the balanced scorecard approach and measuring organizational performance both quantitatively using financial ratios and qualitatively. Challenges to modern strategy evaluation include increased complexity, faster changes, and debates around transparency and top-down vs bottom-up processes. The key is for evaluation to provide timely, accurate information to allow corrective actions if needed.
