The creation of User Stories is an important component in the extraction of User Requirements in any Scrum Project.

While the User Story specifies a specific component that is needed as part of the entire Product Deliverable, it is explained in language that is clear to business User. The technical requirements that underlie this small User declaration are not explained. They are required to be Documented as briefly and concisely as possible. This is attained by breaking down each User Story into a set of Tasks. The Tasks are the foundation of a Sprint; Development Team members total User Stories by taking one or more Tasks and completing them; the Daily Stand-Up Meeting is used to report on Tasks finished the other day and Tasks to be Done today. Tasks can have interdependencies, which gives a pattern to how they are built; they are not tackled randomly, but constantly seen as part of the entire.

User Story – Getting to Task Discovery

When User Stories have actually been created and Prioritised, they are loaded into the Product Backlog in priority order. The Stories with the highest priority are prepared for addition in the next Sprint. During the Sprint Planning Meeting, the Scrum Team discusses how many Stories they can dedicate to and total in the next Sprint. An agreement is reached and a set of User Stories are moved into the Agile Sprint Backlog for execution. Preferably, these Stories ought to now be split into Tasks throughout the same Planning Meeting. Sometimes a separate Meeting is required this, usually since the time limit for the Planning Meeting has been reached.

The Team now examines each Story and identifies the Tasks needed to get the Story “Done”. Each Task has an Estimate of Effort attached to it. This estimate is in either time, determined in hours, or points, as a subset of the Value points Estimated for the User Story as a whole.

If hours are being utilized as a basis for Estimating Tasks, it is also a good idea to make sure that no Task is longer than 8 hours. This is so that it suits a Sprint day. This is unless it is a Task for a paired Team, and the timing is based on a single Team member’s Effort and not Task duration and that two individuals Working on the Task simultaneously can complete it in one day,

Estimating Tasks; can make or break a Project of any kind, not only Agile Scrum projects. It is not comprehending reliances and how they can influence getting Work Done. Dependency Determination is a vital component of Task development.

User Story – Identifying Dependencies

While dependences develop at all levels of Product Requirements, when they are specified at Task level it is simple to understand any slippages in the Sprint. This is specifically true when dependencies are external and outside the control of the Sprint. There are numerous methods of classifying dependences, the Scrum utilizes the exact same 4 classifications that are used in Traditional Project Management:-.

• External.
• Internal.
• Mandatory, and.
• Discretionary.

These are not special, one can have a Mandatory External reliance, for example. One can also have a dependence that is external at the most affordable layer, for example, where one Scrum Team is reliant on another, and internal at Project, Program and Portfolio level. In a Task list for a Sprint, the Risk to the Team takes precedence over choosing whether a dependence is external.

User Story – External Dependencies

‘ External Dependencies’ present the greatest challenge due to the fact that they are outside the Scope and control of the Team. They may be interdependencies between this Team and another Scrum Team in a multi-Scrum Project; or reliance on someone or something outside the Project, such as a vendor providing hardware or a brand-new database.

‘ Internal Dependencies’ are dependences within the Sprint, for circumstances, a Task that needs the database to be revitalized by another Team member prior to a Test-Driven Development pair can construct a test frame and begin carrying out Code.

‘ Mandatory Dependencies’ are non-negotiable and can represent Risk to the Project. Obligatory reliances are typically the reason that the Project was launched in the very first place, for instance a Change to tax legislation.

‘ Discretionary Dependencies’ are reliances that the Team have actually identified will be best for the Project, based on previous experience or Lessons Learnt in a Retrospective for instance. In test-driven Development, the Testing reasoning is constructed before the Code that is to be tested against it. This is the reverse of Traditional Development.

Handling the Task dependencies well is the secret to Project success. There should never ever be a circumstance where even one member of the Team can not continue due to the fact that of a dependency on another Task.

Building the Task List.

As each User Story is broken down into its constituent Tasks, it can be contributed to the Task List. There is no prescribed format for a Task list, however it ought to consist of:-.

• User Story with which the Task is associated.
• A “Handle” for the Task, e.g. a Task No.
• A Task description.
• The Estimated Effort revealed as hours, Story Points or whichever metric the Team has decided to apply.
• Actual Effort in the exact same metrics.
• Status of the Task.
• Dependency on other Tasks.
• Tasks depending on this one.
• Person who has presumed the Task.

We found these books great for finding out more information on Agile Scrum:

The Task list ought to consist of all the Tasks to be finished during the Sprint. When it concerns the Sprint Retrospective, the Estimated vs actual Effort is very important for taking Lessons Learnt about Estimation into the next Sprint.

It is a good idea to carry out some proactive Risk Management when it pertains to dependencies. In Scrum we suggest that you have a dependency Risk Meeting whatever size your Agile Project, where you use Traditional Risk analysis to Identify and categorise Risks (i.e. Probability * Impact) and supply Mitigations in the Event of the dependency producing a traffic jam. Forewarned is forearmed and the Product Owner or Scrum Master can apply any Mitigations to external and/or mandatory Risks, while discretionary and internal Risks should be Mitigated by the Team.
