User Stories Applied: For Agile Software Development

Remember non-functional requirements. Stories can be used to describe a wide variety of requirements types. For example in Figure 1 the Students can download parking passes online user story is a usage requirement similar to a use case whereas the Transcripts will be available online via a standard browser is closer to a technical requirement.

Indicate the estimated size. You can see in Figure 2 that it includes an estimate for the effort to implement the user story.

One way to estimate is to assign user story points to each card, a relative indication of how long it will take a pair of programmers to implement the story. The team then knows that if it currently takes them on average 2.

Indicate the priority. Requirements, including defects identified as part of your independent parallel testing activities or by your operations and support efforts, are prioritized by your project stakeholders or representatives thereof such as product owners and added to the stack in the appropriate place.

You can easily maintain a stack of prioritized requirements by moving the cards around in the stack as appropriate. You can see that the user story card includes an indication of the priority; I often use a scale of one to ten with one being the highest priority.

You want to indicate the priority somehow in case you drop the deck of cards, or if you're using more sophisticated electronic tooling. Pick a strategy that works well for your team.

You also see that the priority changed at some point in the past, this is a normal thing, motivating the team to move the card to another point in the stack. The implication is that your prioritization strategy needs to support this sort of activity. My advice is to keep it simple. Optionally include a unique identifier. The card also includes a unique identifier for the user story, in this case The only reason to do this would be to do this is if you need to maintain some sort of traceability between the user story and other artifacts, in particular acceptance tests.

Figure 2.

User story card informal, high level. He suggests the format: As a role I want something so that benefit.

For example, the user story of Figure 2 could be rewritten as "As a Student I want to download a parking pass so that I can drive to school", as you see in Figure 3. My experience is that this approach helps you to think about who a certain feature is built for and why, and as a result is the approach that I typically prefer to take.

The best advice that I can give is to try both and see which approach works best for you. Figure 3. User story card formal, high level. User Stories and Planning There are two areas where user stories affect the planning process on agile projects: Scheduling. Figure 4 depicts the agile change management management process where work items, including stories, are addressed in priority order.

So, the implication is that the priority assigned to a story affects when the work will be done to implement that requirement. As discussed earlier, project stakeholders are responsible for prioritizing requirements.

Stakeholders also have the right to define new requirements, change their minds about existing requirements, and even reprioritize requirements as they see fit.

However, stakeholders must also be responsible for making decisions and providing information in a timely manner. 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 stories , affect 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 epics , would need to be broken up into smaller stories to meet this criteria.

Figure 4. 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 5 , there 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 cycle , which calls out modeling activities during the delivery life cycle.

There are three common times when stories will be worked on during an agile project: Inception. 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.

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 phase , although this isn't very common as the focus of release is on hardening the system and not on new functionality.

Et Al. Developing ASP. Prentice Hall Google Scholar Our findings emphasize the importance to reflect on granularity when working with user stories. The only reason to do this would be to do this is if you need to maintain some sort of traceability between the user story and other artifacts, in particular acceptance tests.
