This idea comes from Jeff Bezos at Amazon. The goal is to write a press release for your product/feature that comes from the future. This will help to pull out insights about the product and the ideas that each member of your team are holding for that product.
You can decide on how far in the future that you would like your press releases to be with your team.
A "future press release" means just that--it should be written as if the product has already launched, and, more important, is already a success in the marketplace. Before writing your press release, ask yourself: How far in the future am I writing this for and what does success look like when we get there?
The press release should explain why the product improves the customer's experience, what it does better than any other product in its category, and how it delights the customer.
A future release must contain "clear, measurable results you've achieved, including financial, operating, and market share results.”
You should "discuss the issues that need to be addressed to achieve success." This is where the future press release gives your team clarity on the problems they will have to solve to reach the goal.
Outline the issues your team must resolve, but don't worry about not having solved the issues yet. The point is to give your team a sense of accomplishment and a clear description of how their world will look once the issues are resolved.
