The main idea behind Story Maps is that single-list product backlogs are a terrible way to organize and prioritize the work that needs to be done. Story Maps were first introduced by Jeff Patton in 2005. ![]() Typically, an agile development team makes use of a story map in collaborative meetings in identifying the desired results the end-users want to achieve. The user story tool allows you to establish multiple levels and dimensions for a product backlog through the breakdown of user needs as user activities, user tasks, epics, and user stories. User Story Map is becoming a popular user story management technique through the efforts of Jeff Patton and others. Organize your Product Backlog with Story Map The process of breaking a story down into tasks also helps the development team better understand what needs to be done. Thus, the tasks no longer need to be understandable by business users and so can be highly technical. Tasks are usually defined by the people doing the work (developers, QA, etc), whereas stories and epics are generally created by the customer or the product owner on behalf of the customer. Tasks are decomposed parts of a story that get into HOW the story will be completed. A user story must deliver particular value to the user and must be describable in simple language that outlines the desired outcome. User stories should deliver a vertical slice of functionality to the customer that is valuable and complete by the end of an iteration. They are typically estimated using story pointed and defined using INVEST criteria. User stories are the smallest units of user functionality in agile which can be delivered in one agile sprint. ![]() The decomposed stories in an epic have a common objective and a specific outcome or high-level user need or part of the journey or process someone takes in using the service. Epics are usually defined during the initial product roadmap and decomposed into stories in the product backlog as more is learned and is usually written in a User Story format. It probably won’t fit into a sprint and should be broken down into stories. EpicĪn Epic is useful as placeholders for large requirements. By assigning a financial value to Themes, managers can ensure the highest value is being delivered and that the project/program is aligned with its objectives and the strategic direction of the organization. Theme/user FeatureĪ theme provides a convenient way to indicate that a set of related epics have something in common, such as being in the same functional area. Scrum has Product Backlog Items (PBIs), which are often prioritized, split and refined into epics, user stories, technical tasks, spikes and bugs in a just-in-time manner in the backlog grooming process. Scrum doesn’t have “stories”, “epics”, etc. Have you ever been confused by the use of terms like Theme (or feature) or epics in Agile Development? New-comers may not know what differences are and even lead to mistakes. Such a group of user stories is called a theme. But even small user stories from different epics can have something in common. Theme or epics cannot be completed in one sprint so they are broken into more user stories and subsequently a group of related tasks. ![]() Products are typically described by hundreds of requirements which are organized in the product backlog.
