What are the key challenges in strategy implementation?

Many good plans are doomed to failure because they are not implemented correctly. Strategy must be supported by structure, technology, human resources, rewards, information systems, culture, leadership, and so on. Ultimately, the success of a plan depends on how well employees at low levels are able and willing to implement it. Participative management is one of the more popular approaches used by executives to gain employees input and ensure their commitment to strategy implementation.
