Strategy execution is a mix of building the right processes, defining an effective structure which carefully decides accountabilities (DMP, decision making process), developing and constantly updating the required organizational capabilities at all management levels, and delivering transparent performance measurement systems.
However, execution is primarily about fostering and enhancing leadership that motivates and engages your teams as well as managing and planning the implementation of the change.
From middle management all the way up to the owners and CEOs, everyone must get involved in the details of execution. Formulating the strategy is a complex exercise but executing it throughout the organization is even more difficult, full of uncertainties and political blocks. It is where most executives fail. You need to get fully involved and understand that, as a top leader, it is the fundamental point in your management agenda.
