Your goal should be so clearly defined that you can say it in 8 words or less. And so can everyone else at your organization.
Most traditional mission statements are written by boards and then stuck in a drawer and forgotten. They also often talk about what the people inside the organization will do, rather than how what they do benefits those receiving their services.
The kind of goal I am talking about reminds everyone at your organization why you do what you do and is short enough for everyone to remember. If you and they can remember it, you can act on it and more easily be held accountable to it.
I suggest that for your goal you use the model of a WHY statement in 8 words or less. To do this, think in terms of:
Verb + Target + Outcome = Goal
For example, my personal goal is: To lead leaders to success. DecisionGrid's goal is: To provide stewardship tools to inspire great decisions. Verb + Target + Outcome.
This formula helps your team stay action-oriented and keep the person you are serving in mind. People naturally ask: What's in it for me? Your goal should clearly answer that question for them.
In addition to defining goals, The Best Game Model of leadership encourages you to set clear rules, employ qualified players, make a unified strategy, and share scoreboards with stakeholders.
