relationship between epics and user stories estimation

Its like the difference between a right wing politician or a left wing politician. developers can produce a reasonable estimate of the effort to implement it. An Epic may result in a large number of user stories, not all will be. In a sense, stories and epics in agile are similar to stories and epics in film or of epics and initiatives but don't have a ridgid 1-to-1 relationship with them. Requirements (Epic, Feature, User Story), Task Size, and Estimation in Agile/ Scrum There are many reasons why you would want to slice the user story .. This relationship cultivates a more intimate bond between user and.

For complete definitions, examples and best practices, see: Stories Agile Epic vs Initiative In the same way that epics are made up of stories, initiatives are made up of epics.

Initiatives offer another level of organization above epics. In many cases, an initiative compiles epics from multiple teams to achieve a much broader, bigger goal than any of the epics themselves.

While an epic is something you might complete in a month or a quarter, initiatives are often completed in multiple quarters to a year.

Example of epics in an initiative: Each team takes their four or five most important goals for the year and makes PC tickets for each one.

User Stories: An Agile Introduction

These PC tickets are used by the founders and management to understand all the work being done in the company. Learn how to configure Agile Epics Initiatives vs. Themes In many organizations the founders and management team will encourage the pursuit of some aspirational destination.

These are the sometimes super corny goals announced each year or quarter, and themes are how you keep track of them. Initiatives are collections of epics Themes are labels that track high-level organizational goals Initiatives have a structural design. They house epics, and the completion of those epics will lead to the completion of the initiative.

Themes are an organizational tool that allows you to label backlog items, epics, and initiatives to understand what work contributes to what organizational goals. One of our themes this year is Open Work.

Requirements (Epic, Feature, User Story), Task Size, and Estimation in Agile/Scrum

This is a push towards greater transparency, inside and outside of the company. My team is working towards this theme by doing a public retrospective on agile. Being agile and embracing structure are not mutually exclusive, and the structure laid out here is not one size fits all. Developers are responsible for estimating the effort required to implement the things which they will work on, including stories. The implication is that because you can only do so much work in an iteration, the size of the work items including storiesaffect when those work items will be addressed.

Although you may fear that developers don't have the requisite estimating skills, and this is often true at first, the fact is that it doesn't take long for people to get pretty good at estimating when they know that they're going to have to live up to those estimates.

Therefore if you're working in one week iterations each user story must describe less than one week worth of work. Of course, if you aren't taking a non-solo development approach such as pair programming the user story would need to be implementable by a single person within a single iteration.

Large stories, sometimes called epicswould need to be broken up into smaller stories to meet this criteria. Disciplined agile change management process. User Stories Throughout the Agile Life Cycle As you can see in the Disciplined Agile Delivery DAD life cycle of Figure 5there are several distinct "phases" or seasons in the life cycle some people will refer to the agile delivery life cycle as a release rhythm.

Figure 6 depicts the AMDD project life cyclewhich calls out modeling activities during the delivery life cycle. There are three common times when stories will be worked on during an agile project: You often create a stack of user stories during Inception as part of your requirements envisioning activities to identify the scope of your system.

During construction iterations you will identify new stories, split existing stories when you realize that they're too large to be implemented in single iteration, reprioritize existing stories, or remove stories that are no longer considered to be in scope.

User Stories

The point is that your stories evolve over time just like other types of requirements models evolve. Furthermore, enhancement requests may be identified by your support staff during the production phase and then forwarded to a development team as they are working on an upcoming release.

These enhancement requests are effectively new stories albeit in a different format. Sometimes new stories will be identified during the Transition phasealthough this isn't very common as the focus of release is on hardening the system and not on new functionality.

But it does happen, and these stories would be prioritized and placed on the stack in priority order just as you normally would.

The Extended DAD lifecycle. Modeling activities throughout the life cycle of a project. Detailing a User Story Because user stories contain so little information you will need to flesh them out a bit when you first work with them. There are three common times when you would do this: Remember the early definition of "user stories are a reminder to have a conversation with your stakeholders"?

Well, during that conversation you're going to explore the details behind that user story. It is quite common the create screen sketches with stakeholders to explore what they want. It is also common to identify the acceptance criteria, or confirmations, which the stakeholders will use to validate that the user story has been implemented correctly.

Figure 7 shows how the back side of a user story card can be used to capture the confirmations. Of course, other tools which are more sophisticated than index cards can be used for this purpose as well. As part of the estimation effort it is quite common to list programming tasks required to implement the user story.

When you start to work on implementing the user story you may decide to create some rough sketches of what you're going to build, perhaps a flow chart or UML activity diagram representing the relevant business logic.

User story card formal, with confirmations. Epics Epics are large user stories, typically ones which are too big to implement in a single iteration and therefore they need to be disaggregated into smaller user stories at some point. Epics are typically lower priority user stories because once the epic works its way towards the top of the work item stack, see Figure 4it is reorganized into smaller ones.

  • The secrets behind story points and agile estimation
  • Epics, Stories, Themes, and Initiatives

It doesn't make sense to disaggregate a low-priority epic because you'd be investing time on something which you may never get to addressing, unless a portion of the epic is high priority and needs to be teased out.

Remember to defer commitment, in this case model on a just-in-time JIT basis, to increase your overall productivity. Themes A theme is a collection of related user stories.

For example, for a university registration system there might be themes around students, course management, transcript generation, grade administration, financial processing.

Themes are often used to organize stories into releases or to organize them so that various subteams can work on them. Translations Share with friends: The DAD framework is a people-first, learning-oriented hybrid agile approach to IT solution delivery. It has a risk-value delivery lifecycle, is goal-driven, is enterprise aware, and provides the foundation for scaling agile. This book is particularly important for anyone who wants to understand how agile works from end-to-end within an enterprise setting.

Data professionals will find it interesting because it shows how agile modeling and agile database techniques fit into the overall solution delivery process.

Enterprise professionals will find it interesting beause it explicitly promotes the idea that disciplined agile teams should be enterprise aware and therefore work closely with enterprise teams. Existing agile developers will find it interesting because it shows how to extend Scrum-based and Kanban-based strategies to provide a coherent, end-to-end streamlined delivery process.

The Object Primer 3rd Edition: Agile Model Driven Development with UML 2 is an important reference book for agile modelers, describing how to develop 35 types of agile models including all 13 UML 2 diagrams.
