Is your high-level strategy adequately joined up with the realisation of the vision on the ground?
The people who are interested in the strategy are often not very interested in managing the details, and perhaps are frustrated by the questions they are asked by implementers.
The people who are delegated the task of dealing with the detail frequently do not have the strategic ability, or lack the information, to understand fully the context for what they have been asked to do.
The consequence is a gap between intent and delivery which is often filled with misunderstandings, confusion, misalignment and ultimately frustration.
