Feature Matrix - strategic design decisions & tactical planning

As the user centered design approach merges lean UX with agile development we find ourselves running to planning, scoping and management tools to capture, manage and assign the backlogs.  Tools like Jira, Trello and Asana are great at capturing the boards and managing the tickets - but is it enough?  Have we done enough strategic planning and analysis and of the features before assigning them to epic and sprint priority?  If not, what more can be done?

Over the past 10 years Limina and Promet have been using a custom sprint zero tool to capture, review and assign priority on a given drupal/application feature based on user benefit, business benefit and technical complexity.  This talk will share a case study of the tool in use and speak broadly to how other Drupal teams can better manage user experience driven requirements planning.
