Walking skeleton – When making your story map, you start with a description of what kind of main steps you have in your solution. First step: “main page”, second step: “article page” and so on.
Backbone – or hooks to our walking skeleton – is the level above the walking skeleton. It is a useful method to easily get an overview of the entire solution. We do not start with the backbone, because it is easier to consolidate the steps of the walking skeleton. Simple backbone examples are “awareness”, “sales flow” and “after-sales”.
Meat – or what will be your future user stories. In every “main step” of your walking skeleton, you break down the specific step into user stories. If you have not worked with user stories before, they are a formalised way to facilitate a dialogue about smaller parts of the story map. At first, they are only headlines, but during the refinement process that consists of discussions with stakeholders and experts, you will soon get the first part of your product backlog refined up to “definition of ready”.
An important point is that the main difference between a waterfall approach and agile is that –roughly speaking – it is the direction of your slicing that determines your approach and whether you reduce your overall risk continuously or only at the end of the project life. Horizontal slicing includes more steps with fewer user stories at every step of the walking skeleton. Vertical slicing means only one step of your walking skeleton, including all user stories.
A way to foster collective intelligence and conversation
The best story maps are those that have a good mix of cross-functional competencies embedded in them. When you facilitate your storyboard workshops, be aware of how you involve and unfold the intellectual capacity of all attendees and not just the ones who normally talk the most. Inviting other experts in (or outside) your company can create value by them contributing to making your storyboard a creative and very visual way to present your future solutions. The point is that you should try to create your story map in collaboration with people you know think differently than yourself.
