A Good Strategy is abstract enough to develop further, but detail enough to guide through.
A Bad Strategy is too empty to follow through, or too verbose to highlight the KEY...
The leading executive has chosen a goal and called it a strategy. Most of the times the so called "strategy" document only gives the goals objectives but does not state the road map or path to achieve the goal. The executive team needs to provide vision to the staff and then share the differentiating recipe for how their strategic approach will accomplish "goals" that exceed those of their competitors. Simply stating the goals with no indication of how to accomplish them (strategy and tactics) does not rally the troops. Indeed, it's actually the "non-strategy" approach of stratospheric statements that are too lofty for the average employee to connect with and understand how they can contribute to achieving the goal.
There're no such absolute criteria to differentiate good strategy and bad strategy; the right strategy should be ambitious enough to inspire organization up to the next level, and practical enough to execute it with confidence.
