(From A surprisingly simple technique for a rockstar product vision: The Ladder of Needs | by Catherine (Kit) Ulrich | Medium)
Ladder of needs combines the Jobs to Be Done framework with Simon Sineks Start With Why frame work
Creating a ladder –
Why your product does the job
How your product does the job
What jobs your product does
Working from the bottom (what) to the top (center; Why) the Product Ladder Framework helps articulate simply, the reason your product exists (Why), the functional needs that the product must aim to fulfil (How) and the key problems the product must solve (what)
By using the Product Ladder Framework, it provides a structured why to work through and identify these issues. And results in a clear way to articulate this to stakeholders.
