Let's add elevator pitch framework into Vision or Strategy section? This is MECE and at the same time, the most comprehensive way to communicate your product strategy. Best about it is that it realy takes nothing to implement as it's just two sentences.
Here's the framework in case I confused you: FOR (target customer) WHO HAS (customer need), (product name) IS A (market category) THAT (one key benefit). UNLIKE (competition), THE PRODUCT (unique differentiator).
As we start using Aha as core place to publish and alighn for all our products, I feel we badly need it already but will be ok to use just comment field as a blank space to write it.
