A goal answers a question formed as: "what problem are we solving", "what benefit are we creating", and "for what group of people"?
A goal is not a target, or an activity. A goal describes an outcome that we want to achieve, because it has value. The outcome can be a behavioural change, skill acquisition, empowering a new capability. The goal however does not tell us exactly how we're going to achieve that.
When formulating a goal, we should ask "how will we know we have met this goal" - this is where targets or activities may come into play.
When we have an understanding of the desired outcome, the freedom to be creative and a measure of success for the outcome, we are able to Experiment towards a goal
There is little goal forming other than a vague sense of "complete the work" (experimentation and discovery
By establishing clear goals in terms of the valuable outcomes that we want to achieve (Goals tell us the ends not the means), a team can Experiment towards a goal and Learn along the way to frequently evaluate if they're building the right thing in the right way.
Goals tell us the ends not the means
If we Experiment towards a goal then we are defining our work in terms of outcomes - we're thinking about the outcome we want to achieve "the ends" Goals tell us the ends not the means over the specific "means" - therefore, we can establish a definition of done around a need being met.
