Concepts
Adaptive methodologies are guidelines for software development that are flexible and able to adapt to the environmental and project changes. These methodologies include Scrum, Extreme Programming (XP), Scaled Agile Framework (SAFe), and Kanban.
II. Scrum
The Scrum methodology, originally designed for software development, is highly iterative and incremental. It is designed to facilitate team collaboration on complex projects.
Components of Scrum:
- Roles: Scrum Master, Product Owner, and Team.
- Events: Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective.
- Artifacts: Product Backlog, Sprint Backlog, Increment.
III. Extreme Programming (XP)
Extreme Programming focuses on improving software quality and responsiveness to changing customer requirements.
Components of XP:
- Roles: Programmer, Customer, Tester, Tracker, Coach and Consultant.
- Practices: Pair Programming, Test-Driven Development, Continuous Integration, Refactoring, Simple Design.
- Values: Simplicity, Communication, Feedback, Courage, and Respect.
IV. Scaled Agile Framework (SAFe)
The Scaled Agile Framework is a set of organization and workflow patterns for implementing agile practices. It is designed to scale agile methodologies to large enterprises.
Components of SAFe:
- Principles: SAFe is based on nine foundational principles derived from Agile, Lean, and Product Development Flow.
- Levels: Essential SAFe, Portfolio SAFe, Large Solution SAFe, and Full SAFe.
- Roles: SAFe incorporates enterprise leadership, solution management and support, program, and team levels to support and implement these principles.
V. Kanban
Kanban is a visual project management framework utilized to implement Agile that visualizes both the process and the actual work passing through the process.
Components of Kanban:
- Visualization: Kanban board with the Backlog, To Do, In Progress and Done columns.
- Work in Progress Limits: Limiting the ongoing work by stages.
- Feedback Loop: Using meetings to discuss, evaluate progress and improve.
VI. Comparative Table
| Components | Scrum | Extreme Programming | Scaled Agile Framework | Kanban |
|---|---|---|---|---|
| Key Roles | Scrum Master, Product Owner, Team | Programmer, Tester, Customer | Enterprise leadership, solution management and support, program, team | No specific roles defined |
| Artifacts | Product Backlog, Sprint Backlog, Increment | User Stories, Spikes | Portfolio Backlog, Program Backlog, Team Backlog | Kanban Board |
| Events | Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective | Iteration planning, Stand-up meeting, Iteration review, Retrospective | PI Planning, Scrum of Scrums, PO Sync, Inspect & Adapt Workshop | Replenishment Meeting, Delivery Planning Meeting |
| Core Principles | Empiricism, Self-organization, Collaboration | Simplicity, Communication, Feedback, Courage, Respect | Alignment, Transparency, Execution | Visualization, Limit Work in Progress, Manage Flow |
VII. Conclusion
In conclusion, Scrum, Extreme Programming, Scaled Agile Framework, and Kanban are central adaptive methodologies to modern project management. Understanding the components, operational processes, and unique features of these methodologies is fundamental in successfully implementing them. When it comes to choosing a methodology for your project, carefully consider the nature of the project, the work environment, and the team members involved.

- B. Mobility in team organization.
- C. Pair programming.
- D. Knee-jerk reaction to changes.
Answer: D. Knee-jerk reaction to changes.
Explanation: XP supports a discipline and structured way of responding to changes rather than a knee-jerk reaction.

- A. Scrum is only for software development, while Kanban can be used in any industry.
- B. Scrum has roles defined while Kanban does not have specific roles.
- C. In Scrum, changes are not allowed until next sprint, while changes can be made at any time in Kanban.
- D. All of the above.
Answer: D. All of the above.
Explanation: These are some of the fundamental differences that distinguish Scrum and Kanban.
Continuous Integration is a major component of:
- A. Extreme Programming (XP).
- B. Scrum.
- C. Scaled Agile Framework (SAFe).
- D. Kanban.
Answer: A. Extreme Programming (XP).
Explanation: Continuous Integration is one of the XP practices where developers integrate work frequently.
Stakeholder engagement is not a key aspect of Scaled Agile Framework (SAFe). True or False?
- True
- False
Answer: False.
Explanation: SAFe involves all stakeholders through an Agile Release Train, building an aligned mission and vision.
Scrum framework consists of sprints that last between:
- A. A week to a month.
- B. A day to a week.
- C. A month to three months.
- D. A day to two weeks.
Answer: A. A week to a month.
Explanation: In Scrum framework, development work is partitioned into sprints, which typically last between one week and one month.

- False
Answer: True.
Explanation: In contrast to Scrum’s fixed iteration lengths (sprints), Kanban does not pre-plan a fixed length for the completion of a set amount of work.
Great post! I wasn’t aware of the nuances among these adaptive methodologies.
Can anyone explain the main differences between Scrum and Kanban?
How does Extreme Programming (XP) differ from Scrum?
This article really cleared up my confusion about agile frameworks. Thanks!
Does anyone have experience in transitioning from Scrum to SAFe?
What are the core principles of Kanban?
Is SAFe really suitable for large enterprises only?
Thanks for explaining the differences between XP and Scrum. It was very helpful.
