Performing estimation on a user story

Achieving the continuous delivery of workable features is one of the most important goals of any agile development methods. UeXceler has no exception.

In order to keep a balance between development team's workload and the amount of features that can be delivered in each sprint, an accurate estimation of the time required to spend on fulfilling each user story has become very important. Such an estimation has to be performed by the corresponding developer, at the moment the user story is identified. When planning out a sprint, selection of user stories to be achieved can then be made based on the estimation.

UeXceler features an estimation function that allows developers to record the number of days they require to finish their works in each user story.

Entering the estimation

  1. Locate the user story first. Here are some of the typical ways to locate a story.
    • If you own the URL of a user story, open the URL by selecting Diagram > Link from the toolbar. Paste the URL in breadcrumb in press Enter.
    • To locate a user story in a particular use case, open the use case by selecting UeXceler > Use Case first. Find the story under the User Stories tab on the right hand side.
    • To locate a user story in a sprint, open the sprint from the UeXceler > Sprint page and find the story there.
    • You can also find a user story in the UeXceler > User Story page. Note that if your story was added into a sprint, you have to enable the In Sprint option in the Advanced Filter.
  2. Open the story by double clicking on it.
  3. Open the Description tab.

Effect of estimation in sprint planning

Automatic user story assignment

In sprint planning, once you have added a user story into a sprint, UeXceler will help you assign that user story to the members who have had an estimation on that user story. In other words, you will see the user story being listed under the corresponding member column when opening the Members view.

Workload assessment

At the top of each member column in the Members view, you can see the number of days that member will spend on this sprint. Take the following image as example, it's estimated that Andrew will be spending 8 days in completing his work in this sprint.

The number is calculated by adding the number of days estimated for all the user stories assigned to that member. If a member has performed an estimation on a user story but that user story has not been assigned to him in this sprint (i.e. not appearing under his column), the estimation will not be counted in the total number of days.
