The effort to deliver each item is estimated by the development team in story points, or time. By estimating in story points the product owner decouple each item from the developer, and this can be useful especially in dynamic teams where developers are often assigned to other projects after sprint delivery. 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. 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 download-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.

The sprint is a timeboxed effort; that is, it is restricted to a specific duration. Each sprint starts with a sprint planning event that aims to define a sprint backlog, identify the work for the sprint, and make an estimated forecast for the sprint goal. Each sprint ends with a sprint review and sprint retrospective, [13] that reviews progress to show to stakeholders and identify lessons and improvements for the next sprints.

Scrum emphasizes working product at the end of the sprint that is really done. In the case of software, this likely includes that the software has been fully integrated, tested and documented, and is potentially releasable. At the beginning of a sprint, the scrum team holds a sprint planning event [29] to:. Each day during a sprint, the team holds a daily scrum or stand-up with specific guidelines:.

Any impediment e. No detailed discussions should happen during the daily scrum. At the end of a sprint, the team holds two events: Backlog refinement formerly called grooming is the ongoing process of reviewing product backlog items and checking that they are appropriately prepared and ordered in a way that makes them clear and executable for teams once they enter sprints via the sprint planning activity.

Product backlog items may be broken into multiple smaller ones. Acceptance criteria may be clarified. Dependencies may be identified and investigated. The backlog can also include technical debt also known as design debt or code debt. This is a concept in software development that reflects the implied cost of additional rework caused by choosing an easy solution now instead of using a better approach that would take longer.

The product owner can cancel a sprint if necessary. For instance, management may wish the product owner to cancel a sprint if external circumstances negate the value of the sprint goal. If a sprint is abnormally terminated, the next step is to conduct a new sprint planning, where the reason for the termination is reviewed.

The product backlog is a model of work to be done [32] and contains an ordered list of product requirements that a scrum team maintains for a product. The format of product backlog items varies, common formats include user stories , use cases , or any other requirements format the team finds useful.

The product owner prioritizes product backlog items PBIs based on considerations such as risk, business value, dependencies, size, and date needed. The product backlog is what will be delivered, ordered into the sequence in which it should be delivered. It is visible to everyone but may only be changed with the consent of the product owner, who is ultimately responsible for ordering product backlog items for the development team to choose. The product backlog contains the product owner's assessment of business value and the development team's assessment of development effort, which are often, but not always, stated in story points using the rounded Fibonacci scale.

These estimates help the product owner to gauge the timeline and may influence the ordering of product backlog items; for example, if two features have the same business value, the product owner may schedule earlier delivery of the one with the lower development effort because the return on investment is higher or the one with higher development effort because it is more complex or riskier, and they want to retire that risk earlier.

The product backlog and the business value of each product backlog item is the responsibility of the product owner. The effort to deliver each item is estimated by the development team in story points, or time. By estimating in story points the product owner decouple each item from the developer, and this can be useful especially in dynamic teams where developers are often assigned to other projects after sprint delivery.

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.

As the team works through the backlog, it must be assumed that change happens outside their environment—the team can learn about new market opportunities to take advantage of, competitor threats that arise, and feedback from customers that can change the way the product was meant to work.

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.

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.

Scrum works less well in the following circumstances: 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.

Every company has its own distinct organizational structure, culture, and set of business practices, and some are more naturally amenable to this methodology than others.

Like other agile methods, effective adoption of Scrum can be supported through a wide range of tools. Many companies use universal tools, such as spreadsheets to build and maintain artifacts such as the sprint backlog.

There are also open-source and proprietary software packages for Scrum—which are either dedicated to product development using the scrum framework or support multiple product development approaches including Scrum. Other organizations implement Scrum without software tools and maintain their artifacts in hard-copy forms such as paper, whiteboards, and sticky notes.

Scrum is a feedback-driven empirical approach which is, like all empirical process control, underpinned by the three pillars of transparency, inspection, and adaptation.

All work within the scrum framework should be visible to those responsible for the outcome: In order to make these things visible, scrum teams need to frequently inspect the product being developed and how well the team is working. With frequent inspection, the team can spot when their work deviates outside of acceptable limits and adapt their process or the product under development. These three pillars require trust and openness in the team, which the following five values of Scrum enable: The hybridization of Scrum with other software development methodologies is common as Scrum does not cover the whole product development lifecycle ; therefore, organizations find the need to add in additional processes to create a more comprehensive implementation.

For example, at the start of product development, organizations commonly add process guidance on the business case, requirements gathering and prioritization, initial high-level design, and budget and schedule forecasting.

Various authors and communities of people who use Scrum have also suggested more detailed techniques for how to apply or adapt Scrum to particular problems or organizations. Many refer to these methodological techniques as 'patterns' - by analogy with design patterns in architecture and software. Scrumban is a software production model based on Scrum and Kanban.

Scrumban is especially suited for product maintenance with frequent and unexpected work items, such as production defects or programming errors. In such cases the time-limited sprints of the scrum framework may be perceived to be of less benefit, although Scrum's daily events and other practices can still be applied, depending on the team and the situation at hand.

Visualization of the work stages and limitations for simultaneous unfinished work and defects are familiar from the Kanban model. Using these methods, the team's workflow is directed in a way that allows for minimum completion time for each work item or programming error, and on the other hand ensures each team member is constantly employed. To illustrate each stage of work, teams working in the same space often use post-it notes or a large whiteboard.

The major differences between Scrum and Kanban is that in Scrum work is divided into sprints that last a fixed amount of time, whereas in Kanban the flow of work is continuous. This is visible in work stage tables, which in Scrum are emptied after each sprint, whereas in Kanban all tasks are marked on the same table.

Scrum focuses on teams with multifaceted know-how, whereas Kanban makes specialized, functional teams possible. The scrum of scrums is a technique to operate Scrum at scale, for multiple teams working on the same product, allowing them to discuss progress on their interdependencies, focusing on how to coordinate delivering software, [50] especially on areas of overlap and integration.

Depending on the cadence timing of the scrum of scrums, the relevant daily scrum for each scrum team ends by designating one member as an ambassador to participate in the scrum of scrums with ambassadors from other teams. Depending on the context, the ambassadors may be technical contributors or each team's scrum master. Rather than simply a progress update, the scrum of scrums should focus on how teams are collectively working to resolve, mitigate, or accept any risks, impediments, dependencies, and assumptions RIDAs that have been identified.

The scrum of scrums tracks these RIDAs via a backlog of its own, such as a risk board sometimes known as a ROAM board after the initials of resolved, owned, accepted, and mitigated , [51] which typically leads to greater coordination and collaboration between teams.

This should run similar to a daily scrum, with each ambassador answering the following four questions: As Jeff Sutherland commented, [50].

The Scrum of Scrums as I have used it is responsible for delivering the working software of all teams to the Definition of Done at the end of the sprint, or for releases during the sprint. PatientKeeper delivered to production four times per Sprint.

Hubspot delivers live software times a day. The Scrum of Scrums Master is held accountable for making this work. So the Scrum of Scrums is an operational delivery mechanism. Large-scale Scrum LeSS is a product development framework that extends Scrum with scaling rules and guidelines without losing the original purposes of Scrum.

There are two levels to the framework: Large-scale Scrum requires examining the purpose of single-team Scrum elements and figuring out how to reach the same purpose while staying within the constraints of the standard Scrum rules. Bas Vodde and Craig Larman evolved the LeSS framework from their experiences working with large-scale product development, especially in the telecoms and finance industries.

It evolved by taking Scrum and trying many different experiments to discover what works. In , the experiments were solidified into the LeSS framework rules. Less roles, less management, less organizational structures. Many courses in higher education are adapting the scrum framework to give students in both IT and non-IT environments new tools and better insight for dealing with project management. The scrum framework helps students grasp the concepts of the coursework in new ways, while also fostering better teamwork, better communication, breaking tasks down into smaller parts, and it helps students become more self-driven and self-organized.

Scrum has been used to help students become more self-aware and it encourages self-directed learning. Many of the aforementioned skills that are gained by classroom adapted scrum are sought after by many companies and help students become more prepared for the workplace, post-graduation.

It is worth noting that classroom adopted scrum is not pure scrum, as it has to be adapted to fit a week period and often many members of the team must play many roles—this does however help reinforce the Agile philosophy of always being ready for change, constant adaption, and being ready for new requirements and constraints. There is no single certifying body for Scrum and given its non-proprietary nature this is likely to remain the case.

There are currently three generally accepted certifying bodies for Scrum, two American and one European, and the difference between each tends to be largely subjective. They are:.
