Book excerpt: Without effective execution, no business strategy can succeed. Unfortunately, most managers know far more about developing strategy than about executing it -- and overcoming the difficult political and organizational obstacles that stand in their way. In this book, leading consultant and Wharton professor Lawrence Hrebiniak offers the first comprehensive, disciplined process model for making strategy work in the real world. Drawing on his unsurpassed experience, Hrebiniak shows why execution is even more important than many senior executives realize, and sheds powerful new light on why businesses fail to deliver on even their most promising strategies. Next, he offers a systematic roadmap for execution that encompasses every key success factor: organizational structure, coordination, information sharing, incentives, controls, change management, culture, and the role of power and influence in your business. Making Strategy Work concludes with a start-to-finish case study showing how to use Hrebeniak's ideas to address one of today's most difficult business execution challenges: ensuring the success of a merger or acquisition.
