Some very inspiring thoughts in this article of Wharton from March 2005 – Got a Good Strategy? Now Try to Implement It:
Only recently have people begun to realize that effective execution is a competitive business advantage. Companies are now seeing that if they execute better, they perform better. If they integrate long-term and short-term objectives, if they consider incentives, controls and feedback, they execute better. And if one company has that and the other doesn’t, the competitive advantage is clear.
[…] Execution takes longer than people expect. Political and organizational problems typically surface. So you develop a strategy, but you have to go throughout the organization and through dozens of planners to make sure it is carried out. It takes longer. Once execution starts, it could be one or two years, or even require a three-to-five year time frame.
There is still the perception that smart people plan and grunts execute. The short answer is that those who have power or influence have to embrace, believe in and foster execution. Some people think it is a lower-level responsibility – that’s the older perception of execution – but this simply isn’t true.
When companies separate the planning and doing – that’s wrong. Executive strategy requires ownership at all levels, from corporate level managers on down. Strategic success really demands a simultaneous view of planning and doing. The greater the overlap of doers and planners, the greater probability of success.
Execution takes longer. Execution is a process, and not an action or a step. And execution involves more people than strategy formation.
