We love StoriesOnBoard!

We use Stories on Board to create story maps for upcoming software (SAAS) development projects. We start with a smaller group meeting, engineering and business leads, map out the high-level "happy path flow", and then add details on sub-cards. After getting a shared understanding and agreement on that, we use the story map to socialize with a broader set of stakeholders, updating with their feedback as we go. While the story map is a living document, we generally will take a screenshot of it and include it in our technical solution documentation and business documentation on our document management system, Confluence. We find StoriesOnBoard to be extremely user-friendly and easy to use, adding cards and sub-cards, adding details on cards as needed, and with the ability to collapse the view to hide the detail cards. While a user experience is almost never linear, we use the "happy path" to map out as best as possible a linear flow.
