The Daily Stand-up is a short, daily meeting held by Scrum teams to synchronize their work, identify and address any impediments, and ensure that they are on track to achieve the sprint goal. It is typically held at the same time and place each day, and it should not last longer than 15 minutes.
**Purpose of the Daily Stand-up**
The Daily Stand-up serves several important purposes:
* **Synchronization:** It helps team members stay informed about each other's work and ensures that everyone is aligned on the sprint goal.
* **Problem-solving:** It provides a forum for team members to identify and address any impediments that are blocking their progress.
* **Adaptation:** It allows the team to adapt their plan as needed based on new information or changes in priorities.
**Questions for Team Members**
During the Daily Stand-up, each team member will answer three questions:
1. **What did I accomplish yesterday?**
This question helps team members reflect on their progress and share their accomplishments with the team.
2. **What will I work on today?**
This question helps team members communicate their plans for the day and ensure that everyone is working towards the same goal.
3. **Are there any impediments in my way?**
This question helps team members identify any obstacles that are preventing them from making progress and allows the team to work together to find solutions.
**Conducting the Daily Stand-up**
The Daily Stand-up should be a quick and focused meeting. Here are some tips for conducting an effective Daily Stand-up:
* Start on time and end on time.
* Have everyone stand up. This helps to keep the meeting short and focused.
* Follow the three-question format.
* Use a timer to keep the meeting on track.
* Encourage active participation from all team members.
* Address any impediments immediately.
* End the meeting by summarizing the key takeaways.
The Daily Stand-up is a valuable tool for Scrum teams to improve their communication, collaboration, and productivity. By following these tips, you can ensure that your Daily Stand-ups are effective and help your team achieve its goals.

# The Scrum Guide
## The Definitive Guide to Scrum: The Rules of the Game
## Ken Schwaber & Jeff Sutherland
## November 2020
## Purpose of the Scrum Guide
We developed Scrum in the early 1990s. We wrote the first version of the Scrum Guide in 2010 to help
people worldwide understand Scrum. We have evolved the Guide since then through small, functional
updates. Together, we stand behind it.
The Scrum Guide contains the definition of Scrum. Each element of the framework serves a specific
purpose that is essential to the overall value and results realized with Scrum. Changing the core design
or ideas of Scrum, leaving out elements, or not following the rules of Scrum, covers up problems and
limits the benefits of Scrum, potentially even rendering it useless.
We follow the growing use of Scrum within an ever-growing complex world. We are humbled to see
Scrum being adopted in many domains holding essentially complex work, beyond software product
development where Scrum has its roots. As Scrum’s use spreads, developers, researchers, analysts,
scientists, and other specialists do the work. We use the word “developers” in Scrum not to exclude,
but to simplify. If you get value from Scrum, consider yourself included.
As Scrum is being used, patterns, processes, and insights that fit the Scrum framework as described in
this document, may be found, applied and devised. Their description is beyond the purpose of the
Scrum Guide because they are context sensitive and differ widely between Scrum uses. Such tactics for
using within the Scrum framework vary widely and are described elsewhere.

## Scrum Definition
Scrum is a lightweight framework that helps people, teams and organizations generate value through
adaptive solutions for complex problems.
In a nutshell, Scrum requires a Scrum Master to foster an environment where:
1. A Product Owner orders the work for a complex problem into a Product Backlog.
2. The Scrum Team turns a selection of the work into an Increment of value during a Sprint.
3. The Scrum Team and its stakeholders inspect the results and adjust for the next Sprint.
4. _Repeat_
Scrum is simple. Try it as is and determine if its philosophy, theory, and structure help to achieve goals
and create value. The Scrum framework is purposefully incomplete, only defining the parts required to
implement Scrum theory. Scrum is built upon by the collective intelligence of the people using it. Rather
than provide people with detailed instructions, the rules of Scrum guide their relationships and
interactions.
Various processes, techniques and methods can be employed within the framework. Scrum wraps
around existing practices or renders them unnecessary. Scrum makes visible the relative efficacy of
current management, environment, and work techniques, so that improvements can be made.
## Scrum Theory
Scrum is founded on empiricism and lean thinking. Empiricism asserts that knowledge comes from
experience and making decisions based on what is observed. Lean thinking reduces waste and focuses
on the essentials.
Scrum employs an iterative, incremental approach to optimize predictability and to control risk. Scrum
engages groups of people who collectively have all the skills and expertise to do the work and share or
acquire such skills as needed.
Scrum combines four formal events for inspection and adaptation within a containing event, the Sprint.
These events work because they implement the empirical Scrum pillars of transparency, inspection, and
adaptation.
### Transparency
The emergent process and work must be visible to those performing the work as well as those receiving
the work. With Scrum, important decisions are based on the perceived state of its three formal artifacts.
Artifacts that have low transparency can lead to decisions that diminish value and increase risk.
Transparency enables inspection. Inspection without transparency is misleading and wasteful.
### Inspection
The Scrum artifacts and the progress toward agreed goals must be inspected frequently and diligently to
detect potentially undesirable variances or problems. To help with inspection, Scrum provides cadence
in the form of its five events.
Inspection enables adaptation. Inspection without adaptation is considered pointless. Scrum events are
designed to provoke change.
### Adaptation
If any aspects of a process deviate outside acceptable limits or if the resulting product is unacceptable,
the process being applied or the materials being produced must be adjusted. The adjustment must be
made as soon as possible to minimize further deviation.
Adaptation becomes more difficult when the people involved are not empowered or self-managing. A
Scrum Team is expected to adapt the moment it learns anything new through inspection.
## Scrum Values
Successful use of Scrum depends on people becoming more proficient in living five values:
```markdown
Commitment, Focus, Openness, Respect, and Courage
```
The Scrum Team commits to achieving its goals and to supporting each other. Their primary focus is on
the work of the Sprint to make the best possible progress toward these goals. The Scrum Team and its
stakeholders are open about the work and the challenges. Scrum Team members respect each other to
be capable, independent people, and are respected as such by the people with whom they work. The
Scrum Team members have the courage to do the right thing, to work on tough problems.
These values give direction to the Scrum Team with regard to their work, actions, and behavior. The
decisions that are made, the steps taken, and the way Scrum is used should reinforce these values, not
diminish or undermine them. The Scrum Team members learn and explore the values as they work with
the Scrum events and artifacts. When these values are embodied by the Scrum Team and the people
they work with, the empirical Scrum pillars of transparency, inspection, and adaptation come to life
building trust.
## Scrum Team
The fundamental unit of Scrum is a small team of people, a Scrum Team. The Scrum Team consists of
one Scrum Master, one Product Owner, and Developers. Within a Scrum Team, there are no sub-teams
or hierarchies. It is a cohesive unit of professionals focused on one objective at a time, the Product Goal.
Scrum Teams are cross-functional, meaning the members have all the skills necessary to create value
each Sprint. They are also self-managing, meaning they internally decide who does what, when, and
how.
The Scrum Team is small enough to remain nimble and large enough to complete significant work within
a Sprint, typically 10 or fewer people. In general, we have found that smaller teams communicate better
and are more productive. If Scrum Teams become too large, they should consider reorganizing into
multiple cohesive Scrum Teams, each focused on the same product. Therefore, they should share the
same Product Goal, Product Backlog, and Product Owner.
The Scrum Team is responsible for all product-related activities from stakeholder collaboration,
verification, maintenance, operation, experimentation, research and development, and anything else
that might be required. They are structured and empowered by the organization to manage their own
work. Working in Sprints at a sustainable pace improves the Scrum Team’s focus and consistency.
The entire Scrum Team is accountable for creating a valuable, useful Increment every Sprint. Scrum
defines three specific accountabilities within the Scrum Team: the Developers, the Product Owner, and
the Scrum Master.
### Developers
Developers are the people in the Scrum Team that are committed to creating any aspect of a usable
Increment each Sprint.
The specific skills needed by the Developers are often broad and will vary with the domain of work.
However, the Developers are always accountable for:
```markdown
- Creating a plan for the Sprint, the Sprint Backlog;
- Instilling quality by adhering to a Definition of Done;
- Adapting their plan each day toward the Sprint Goal; and,
- Holding each other accountable as professionals.
```
### Product Owner
The Product Owner is accountable for maximizing the value of the product resulting from the work of
the Scrum Team. How this is done may vary widely across organizations, Scrum Teams, and individuals.
The Product Owner is also accountable for effective Product Backlog management, which includes:
```markdown
- Developing and explicitly communicating the Product Goal;
- Creating and clearly communicating Product Backlog items;
- Ordering Product Backlog items; and,
- Ensuring that the Product Backlog is transparent, visible and understood.
```
The Product Owner may do the above work or may delegate the responsibility to others. Regardless, the
Product Owner remains accountable.
For Product Owners to succeed, the entire organization must respect their decisions. These decisions
are visible in the content and ordering of the Product Backlog, and through the inspectable increment at
the Sprint Review.
The Product Owner is one person, not a committee. The Product Owner may represent the needs of
many stakeholders in the Product Backlog. Those wanting to change the Product Backlog can do so by
trying to convince the Product Owner.
### Scrum Master
The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by
helping everyone understand Scrum theory and practice, both within the Scrum Team and the
organization.
The Scrum Master is accountable for the Scrum Team’s effectiveness. They do this by enabling the
Scrum Team to improve its practices, within the Scrum framework.
Scrum Masters are true leaders who serve the Scrum Team and the larger organization.
The Scrum Master serves the Scrum Team in several ways, including:
```markdown
- Coaching the team members in self-management and cross-functionality;
- Helping the Scrum Team focus on creating high-value Increments that meet the Definition of
Done;
- Causing the removal of impediments to the Scrum Team’s progress; and,
- Ensuring that all Scrum events take place and are positive, productive, and kept within the
timebox.
```
The Scrum Master serves the Product Owner in several ways, including:
```markdown
- Helping find techniques for effective Product Goal definition and Product Backlog management;
- Helping the Scrum Team understand the need for clear and concise Product Backlog items;
- Helping establish empirical product planning for a complex environment; and,
- Facilitating stakeholder collaboration as requested or needed.
```
The Scrum Master serves the organization in several ways, including:
```markdown
- Leading, training, and coaching the organization in its Scrum adoption;
- Planning and advising Scrum implementations within the organization;
- Helping employees and stakeholders understand and enact an empirical approach for complex
work; and,
- Removing barriers between stakeholders and Scrum Teams.
```
## Scrum Events
The Sprint is a container for all other events. Each event in Scrum is a formal opportunity to inspect and
adapt Scrum artifacts. These events are specifically designed to enable the transparency required.
Failure to operate any events as prescribed results in lost opportunities to inspect and adapt. Events are
used in Scrum to create regularity and to minimize the need for meetings not defined in Scrum.
Optimally, all events are held at the same time and place to reduce complexity.
### The Sprint
Sprints are the heartbeat of Scrum, where ideas are turned into value.
They are fixed length events of one month or less to create consistency. A new Sprint starts immediately
after the conclusion of the previous Sprint.
All the work necessary to achieve the Product Goal, including Sprint Planning, Daily Scrums, Sprint
Review, and Sprint Retrospective, happen within Sprints.
During the Sprint:
```markdown
- No changes are made that would endanger the Sprint Goal;
- Quality does not decrease;
- The Product Backlog is refined as needed; and,
- Scope may be clarified and renegotiated with the Product Owner as more is learned.
```
Sprints enable predictability by ensuring inspection and adaptation of progress toward a Product Goal at
least every calendar month. When a Sprint’s horizon is too long the Sprint Goal may become invalid,
complexity may rise, and risk may increase. Shorter Sprints can be employed to generate more learning
cycles and limit risk of cost and effort to a smaller time frame. Each Sprint may be considered a short
project.
Various practices exist to forecast progress, like burn-downs, burn-ups, or cumulative flows. While
proven useful, these do not replace the importance of empiricism. In complex environments, what will
happen is unknown. Only what has already happened may be used for forward-looking decision making.
A Sprint could be cancelled if the Sprint Goal becomes obsolete. Only the Product Owner has the
authority to cancel the Sprint.
### Sprint Planning
Sprint Planning initiates the Sprint by laying out the work to be performed for the Sprint. This resulting
plan is created by the collaborative work of the entire Scrum Team.
The Product Owner ensures that attendees are prepared to discuss the most important Product Backlog
items and how they map to the Product Goal. The Scrum Team may also invite other people to attend
Sprint Planning to provide advice.
Sprint Planning addresses the following topics:
Topic One: Why is this Sprint valuable?
The Product Owner proposes how the product could increase its value and utility in the current Sprint.
The whole Scrum Team then collaborates to define a Sprint Goal that communicates why the Sprint is
valuable to stakeholders. The Sprint Goal must be finalized prior to the end of Sprint Planning.
Topic Two: What can be Done this Sprint?
Through discussion with the Product Owner, the Developers select items from the Product Backlog to
include in the current Sprint. The Scrum Team may refine these items during this process, which
increases understanding and confidence.
Selecting how much can be completed within a Sprint may be challenging. However, the more the
Developers know about their past performance, their upcoming capacity, and their Definition of Done,
the more confident they will be in their Sprint forecasts.
Topic Three: How will the chosen work get done?
For each selected Product Backlog item, the Developers plan the work necessary to create an Increment
that meets the Definition of Done. This is often done by decomposing Product Backlog items into
smaller work items of one day or less. How this is done is at the sole discretion of the Developers. No
one else tells them how to turn Product Backlog items into Increments of value.
The Sprint Goal, the Product Backlog items selected for the Sprint, plus the plan for delivering them are
together referred to as the Sprint Backlog.
Sprint Planning is timeboxed to a maximum of eight hours for a one-month Sprint. For shorter Sprints,
the event is usually shorter.
### Daily Scrum
The purpose of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint
Backlog as necessary, adjusting the upcoming planned work.
The Daily Scrum is a 15-minute event for the Developers of the Scrum Team. To reduce complexity, it is
held at the same time and place every working day of the Sprint. If the Product Owner or Scrum Master
are actively working on items in the Sprint Backlog, they participate as Developers.
The Developers can select whatever structure and techniques they want, as long as their Daily Scrum
focuses on progress toward the Sprint Goal and produces an actionable plan for the next day of work.
This creates focus and improves self-management.
Daily Scrums improve communications, identify impediments, promote quick decision-making, and
consequently eliminate the need for other meetings.
The Daily Scrum is not the only time Developers are allowed to adjust their plan. They often meet
throughout the day for more detailed discussions about adapting or re-planning the rest of the Sprint’s
work.
### Sprint Review
The purpose of the Sprint Review is to inspect the outcome of the Sprint and determine future
adaptations. The Scrum Team presents the results of their work to key stakeholders and progress
toward the Product Goal is discussed.
During the event, the Scrum Team and stakeholders review what was accomplished in the Sprint and
what has changed in their environment. Based on this information, attendees collaborate on what to do
next. The Product Backlog may also be adjusted to meet new opportunities. The Sprint Review is a
working session and the Scrum Team should avoid limiting it to a presentation.
The Sprint Review is the second to last event of the Sprint and is timeboxed to a maximum of four hours
for a one-month Sprint. For shorter Sprints, the event is usually shorter.
### Sprint Retrospective
The purpose of the Sprint Retrospective is to plan ways to increase quality and effectiveness.
The Scrum Team inspects how the last Sprint went with regards to individuals, interactions, processes,
tools, and their Definition of Done. Inspected elements often vary with the domain of work.
Assumptions that led them astray are identified and their origins explored. The Scrum Team discusses
what went well during the Sprint, what problems it encountered, and how those problems were (or
were not) solved.
The Scrum Team identifies the most helpful changes to improve its effectiveness. The most impactful
improvements are addressed as soon as possible. They may even be added to the Sprint Backlog for the
next Sprint.
The Sprint Retrospective concludes the Sprint. It is timeboxed to a maximum of three hours for a one-
month Sprint. For shorter Sprints, the event is usually shorter.
## Scrum Artifacts
Scrum’s artifacts represent work or value. They are designed to maximize transparency of key
information. Thus, everyone inspecting them has the same basis for adaptation.
Each artifact contains a commitment to ensure it provides information that enhances transparency and
focus against which progress can be measured:
```markdown
- For the Product Backlog it is the Product Goal.
- For the Sprint Backlog it is the Sprint Goal.
- For the Increment it is the Definition of Done.
```
These commitments exist to reinforce empiricism and the Scrum values for the Scrum Team and their
stakeholders.
### Product Backlog
The Product Backlog is an emergent, ordered list of what is needed to improve the product. It is the
single source of work undertaken by the Scrum Team.
Product Backlog items that can be Done by the Scrum Team within one Sprint are deemed ready for
selection in a Sprint Planning event. They usually acquire this degree of transparency after refining
activities. Product Backlog refinement is the act of breaking down and further defining Product Backlog
items into smaller more precise items. This is an ongoing activity to add details, such as a description,
order, and size. Attributes often vary with the domain of work.
The Developers who will be doing the work are responsible for the sizing. The Product Owner may
influence the Developers by helping them understand and select trade-offs.
#### Commitment: Product Goal
The Product Goal describes a future state of the product which can serve as a target for the Scrum Team
to plan against. The Product Goal is in the Product Backlog. The rest of the Product Backlog emerges to
define “what” will fulfill the Product Goal.
```markdown
A product is a vehicle to deliver value. It has a clear boundary, known stakeholders, well-defined
users or customers. A product could be a service, a physical product, or something more abstract.
```
The Product Goal is the long-term objective for the Scrum Team. They must fulfill (or abandon) one
objective before taking on the next.
### Sprint Backlog
The Sprint Backlog is composed of the Sprint Goal (why), the set of Product Backlog items selected for
the Sprint (what), as well as an actionable plan for delivering the Increment (how).
The Sprint Backlog is a plan by and for the Developers. It is a highly visible, real-time picture of the work
that the Developers plan to accomplish during the Sprint in order to achieve the Sprint Goal.
Consequently, the Sprint Backlog is updated throughout the Sprint as more is learned. It should have
enough detail that they can inspect their progress in the Daily Scrum.
#### Commitment: Sprint Goal
The Sprint Goal is the single objective for the Sprint. Although the Sprint Goal is a commitment by the
Developers, it provides flexibility in terms of the exact work needed to achieve it. The Sprint Goal also
creates coherence and focus, encouraging the Scrum Team to work together rather than on separate
initiatives.
The Sprint Goal is created during the Sprint Planning event and then added to the Sprint Backlog. As the
Developers work during the Sprint, they keep the Sprint Goal in mind. If the work turns out to be
different than they expected, they collaborate with the Product Owner to negotiate the scope of the
Sprint Backlog within the Sprint without affecting the Sprint Goal.
### Increment
An Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all
prior Increments and thoroughly verified, ensuring that all Increments work together. In order to
provide value, the Increment must be usable.
Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the
Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders
prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value.
Work cannot be considered part of an Increment unless it meets the Definition of Done.
#### Commitment: Definition of Done
The Definition of Done is a formal description of the state of the Increment when it meets the quality
measures required for the product.
The moment a Product Backlog item meets the Definition of Done, an Increment is born.
The Definition of Done creates transparency by providing everyone a shared understanding of what
work was completed as part of the Increment. If a Product Backlog item does not meet the Definition of
Done, it cannot be released or even presented at the Sprint Review. Instead, it returns to the Product
Backlog for future consideration.
If the Definition of Done for an increment is part of the standards of the organization, all Scrum Teams
must follow it as a minimum. If it is not an organizational standard, the Scrum Team must create a
Definition of Done appropriate for the product.
The Developers are required to conform to the Definition of Done. If there are multiple Scrum Teams
working together on a product, they must mutually define and comply with the same Definition of Done.
## End Note
Scrum is free and offered in this Guide. The Scrum framework, as outlined herein, is immutable. While
implementing only parts of Scrum is possible, the result is not Scrum. Scrum exists only in its entirety
and functions well as a container for other techniques, methodologies, and practices.
### Acknowledgements
#### People
Of the thousands of people who have contributed to Scrum, we should single out those who were
instrumental at the start: Jeff Sutherland worked with Jeff McKenna and John Scumniotales, and Ken
Schwaber worked with Mike Smith and Chris Martin, and all of them worked together. Many others
contributed in the ensuing years and without their help Scrum would not be refined as it is today.
#### Scrum Guide History
Ken Schwaber and Jeff Sutherland first co-presented Scrum at the OOPSLA Conference in 1995. It
essentially documented the learning that Ken and Jeff gained over the previous few years and made
public the first formal definition of Scrum.
The Scrum Guide documents Scrum as developed, evolved, and sustained for 30-plus years by Jeff
Sutherland and Ken Schwaber. Other sources provide patterns, processes, and insights that complement
the Scrum framework. These may increase productivity, value, creativity, and satisfaction with the
results.
The complete history of Scrum is described elsewhere. To honor the first places where it was tried and
proven, we recognize Individual Inc., Newspage, Fidelity Investments, and IDX (now GE Medical).
