Every team should have a product owner, although in many instances they will work with more than one team. The product owner gathers input and takes feedback from, and is lobbied by, many people, but ultimately makes the call on what gets built.

The product backlog: Captures requests to modify a product—including new features, replacing old features, removing features, and fixing issues Ensures the development team has work that maximizes business benefit to the product owner Typically, the product owner and the scrum team come together and write down everything that must be prioritized, and this becomes content for the first sprint—which is a block of time meant for focused work on selected items that can be accommodated within a timeframe.

The product backlog can evolve as new information surfaces about the product and about its customers, and so later sprints may address new work.

Management[ edit ] A product backlog, in its simplest form, is merely a list of items to work on. Having well-established rules about how work is added, removed and ordered helps the whole team make better decisions about how to change the product. The team then chooses which items they can complete in the coming sprint. On the scrum board, the team moves items from the product backlog to the sprint backlog, which is the list of items they will build.

Conceptually, it is ideal for the team to only select what they think they can accomplish from the top of the list, but it is not unusual to see in practice that teams are able to take lower-priority items from the list along with the top ones selected.

This normally happens because there is time left within the sprint to accommodate more work. Items at the top of the backlog, the items to work on first, should be broken down into stories that are suitable for the development team to work on. The further down the backlog goes, the less refined the items should be. As Schwaber and Beedle put it "The lower the priority, the less detail until you can barely make out the backlog item.

All of these new ideas tend to trigger the team to adapt the backlog to incorporate new knowledge. This is part of the fundamental mindset of an agile team.

The world changes, the backlog is never finished. The development team should keep in mind its past performance assessing its capacity for the new-sprint, and use this as a guideline of how much 'effort' they can complete.

The product backlog items may be broken down into tasks by the development team. This promotes self-organization of the development team and developer buy-in. The sprint backlog is the property of the development team, and all included estimates are provided by the development team. Often an accompanying task board is used to see and change the state of the tasks of the current sprint, like to do, in progress and done.

Once a sprint backlog is committed, no additional work can be added to the sprint backlog except by the team. Once a sprint has been delivered, the product backlog is analyzed and reprioritized if necessary, and the next set of functionality is selected for the next sprint.

Product increment[ edit ] The potentially releasable increment is the sum of all the product backlog items completed during a sprint, integrated with the work of all previous sprints. At the end of a sprint, the increment must be complete, according to the scrum team's definition of "done" DoD , fully functioning, and in a usable condition regardless of whether the product owner decides to actually release it.

Extensions[ edit ] The following artifacts are commonly used, although not considered by all as a core part of Scrum: Sprint burn-down chart[ edit ] A sample burn-down chart for a completed sprint, showing remaining effort at the end of each day. Main article: Burn down chart The sprint burn-down chart is a publicly displayed chart showing remaining work in the sprint backlog. It also provides quick visualizations for reference.

The horizontal axis of the sprint burn-down chart shows the days in a sprint, while the vertical axis shows the amount of work remaining each day typically representing the estimate of hours of work remaining. During sprint planning, the ideal burndown chart is plotted.

Then, during the sprint, each member picks up tasks from the sprint backlog and works on them. At the end of the day, they update the remaining hours for tasks to be completed. In such a way, the actual burndown chart is updated day by day. It should not be confused with an earned value chart. Release burn-up chart[ edit ] A sample burn-up chart for a release, showing scope completed each sprint The release burn-up chart is a way for the team to provide visibility and track progress toward a release.

Updated at the end of each sprint, it shows progress toward delivering a forecast scope. The horizontal axis of the release burn-up chart shows the sprints in a release, while the vertical axis shows the amount of work completed at the end of each sprint typically representing cumulative story points of work completed.

Progress is plotted as a line that grows up to meet a horizontal line that represents the forecast scope; often shown with a forecast, based on progress to date, that indicates how much scope might be completed by a given release date or how many sprints it will take to complete the given scope.

The release burn-up chart makes it easy to see how much work has been completed, how much work has been added or removed if the horizontal scope line moves , and how much work is left to be done.

Definition of ready DoR [ edit ] The start-criteria to determine whether the specifications and inputs are set enough to start the work item , i.

Definition of done DoD [ edit ] The exit-criteria to determine whether a product backlog item is complete. In many cases, the DoD requires that all regression tests be successful.

The definition of done may vary from one scrum team to another but must be consistent within one team. The number is derived by evaluating the work typically in user story points completed in the last sprint.

The collection of historical velocity data is a guideline for assisting the team in understanding how much work they can likely achieve in a future sprint. Spike[ edit ] A time-boxed period used to research a concept or create a simple prototype. Spikes can either be planned to take place in between sprints or, for larger teams, a spike might be accepted as one of many sprint delivery objectives. Spikes are often introduced before the delivery of large or complex product backlog items in order to secure budget, expand knowledge, or produce a proof of concept.

The duration and objective s of a spike is agreed between product owner and development team before the start. Unlike sprint commitments, spikes may or may not deliver tangible, shippable, valuable functionality. For example, the objective of a spike might be to successfully reach a decision on a course of action. The spike is over when the time is up, not necessarily when the objective has been delivered.

It might just be a very narrow implementation of the functionality but is not throwaway code. It is of production quality, and the rest of the iterations can build on this code.

The name has military origins as ammunition that makes the path of the bullet visible, allowing for corrections. Often these implementations are a 'quick shot' through all layers of an application, such as connecting a single form's input field to the back-end, to prove the layers connect as expected.

While recent improvements in technology have reduced the impact of these barriers e. This can be encouraged by good Scrum leadership. While team members with very specific skills can and do contribute well, they should be encouraged to learn more about and collaborate with other disciplines. Products with many external dependencies: In Scrum, dividing product development into short sprints requires careful planning; external dependencies, such as user acceptance testing or coordination with other teams, can lead to delays and the failure of individual sprints.

Products that are mature or legacy or with regulated quality control : In Scrum, product increments should be fully developed and tested in a single sprint; products that need large amounts of regression testing or safety testing e.

From a business perspective, Scrum has many virtues, one of which is that it is designed to yield the best business solutions. However, the efficiency by which it does so in any given organization can vary widely and is largely dependent on the ability of the organization to adhere to the implementation guidelines.

For instance if a user story is 5 using Fibonacci sequence it remains 5 regardless of how many developers are working on it. Story points define the effort in a time-box, so they do not change with time. For instance in one hour we can walk, run, or climb, but the effort is clearly different. Also the gap between each number in Fibonacci or other sequences , is suggesting the team to deliver accurate estimates.

For example 1,2 or 3 have similar efforts, 1 being trivial, but if the team estimate an 8 for 13, the impact on both delivery and budget can be significant.

For instance a 5 for one team, could be a 2 for another having senior developers and higher skills. Every team should have a product owner, although in many instances they will work with more than one team.
