Scrum Definition
Scrum is a lightweight framework that helps people, teams and organizations generate value through adaptive solutions for complex problems.
Cycle of scrum in 4 steps
Scrum requires a Scrum Master to foster an environment where:
- A Product Owner orders the work for a complex problem into a Product Backlog.
- The Scrum Team turns a selection of the work into an Increment of value during a Sprint.
- The Scrum Team and its stakeholders inspect the results and adjust for the next Sprint.
- Repeat
Scrum Theory
Lean and Empiricism:
Empiricism asserts that knowledge comes from experience and making decisions based on what is observed. Lean thinking reduces waste and focuses on the essentials.
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
work must be visible to those performing the work as well as those receiving the work
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
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
Commitment, Focus, Openness, Respect, and Courage
Commitment
The Scrum Team commits to achieving its goals and to supporting each other.
Openness
The Scrum Team and its stakeholders are open about the work and the challenges
Respect
Scrum Team members respect each other to be capable, independent people, and are respected as such by the people with whom they work.
Courage
The Scrum Team members have the courage to do the right thing, to work on tough problems.
Focus
The scrum teams primary focus is on the work of the Sprint to make the best possible progress toward these goals.
Theory behind values
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 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.
Developers are always accountable for:
● 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.
