Using this approach, you "traffic-light" the "leaks" in your marketing processes and address the red leaks first, in the right order.
But it's not a once-and-you're-done activity.
I recommend clients review their leaks every six months or so, to stay focused on their priorities and on track to achieve their long-term goals.
As you might imagine, after working on addressing a red leak in your business, hopefully it will turn orange and then eventually green. However, that doesn't always happen. Why? Because you are working towards a constantly moving goal-post.
