When I work with executives, I always recommend helping their teams get clear on what they want to achieve, why, how, and how they'll know they've accomplished it.
Said another way, you need to define your overall objective, determine what goals are needed to realize it, understand the strategies needed to achieve each goal, and then define quantifiable success metrics to keep everyone focused.
Clearly define the team's overall objective, which should be linked to the team's ultimate purpose.
Create strategies to accomplish each goal by considering what it will take to achieve the goal, your available resources, and your timeline.
