If “Why” is the goal you want to achieve along with a value metric to validate the business objective and the “Who” is the actor performing the act, you can identify “How” you can achieve this impact. Once the impact is identified, you can come up with “What” is needed. This is your deliverable. The resulting impact map allows you to compare the various options and measure the outcome.

Each deliverable in turn can be broken down into tangible Product Backlog items, in the form of user stories, for example. Given that the goal, the actor, and the deliverable are established, defining the Product Backlog items is more straightforward.
