Agile methodology is a way of developing software and organizing complex work around customer value, close collaboration, frequent delivery of usable results, and adaptation to change. It is not one prescribed process. Agile is the broader set of values and principles first expressed in the 2001 Manifesto for Agile Software Development; Scrum, Kanban, Extreme Programming and SAFe are different ways teams may apply related ideas.
What is Agile methodology?
Agile is a values-and-principles-based approach. Instead of trying to define every requirement years in advance, a team delivers useful increments, gathers feedback, learns, and adjusts what it does next. Planning still matters, but plans are treated as informed forecasts that can change when evidence or priorities change.
The Manifesto was created in 2001 by 17 software practitioners. Its wording establishes priorities rather than absolute rules: the items on the right remain valuable, but the items on the left receive greater emphasis.
What are the four values of Agile?
| Agile values more | While still valuing | Practical meaning |
|---|---|---|
| Individuals and interactions | Processes and tools | Good communication and judgment come before relying on a tool or procedure to solve a people problem. |
| Working software | Comprehensive documentation | A usable product provides stronger evidence of progress than documents alone; necessary documentation is still produced. |
| Customer collaboration | Contract negotiation | Customers and delivery teams work together as the product becomes clearer, while agreements and commercial obligations still matter. |
| Responding to change | Following a plan | A team updates its direction when new information matters instead of treating an old plan as unchangeable. |
These are relative priorities, not permission to abandon documentation, contracts, planning, standards or governance.

What are the 12 Agile principles?
- Satisfy customers through early and continuous delivery of valuable software.
- Welcome changing requirements, even late in development, when change improves the product.
- Deliver working software frequently, with a preference for shorter timescales.
- Keep business people and developers working together throughout the project.
- Build projects around motivated people, give them the support they need, and trust them to do the work.
- Use direct conversation as the most effective way to communicate within a development team.
- “Working software is the primary measure of progress.” — Principles behind the Agile Manifesto.
- Maintain a sustainable pace so sponsors, developers and users can continue indefinitely.
- Give continuous attention to technical excellence and good design, which increases agility.
- Value simplicity: maximize the amount of work not done.
- Let the best architectures, requirements and designs emerge from self-organizing teams.
- At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
How does Agile work in practice?
Agile is best understood as a feedback loop rather than a fixed sequence of ceremonies.
- Choose valuable work. Make the next objective explicit and order work by customer or organizational value.
- Clarify the outcome. Collaborate with customers, domain experts and the people doing the work so the problem and acceptance conditions are understood.
- Build a small usable increment. Integrate, test and demonstrate a slice that could provide value, rather than hiding all progress until the end.
- Inspect the result. Use customer feedback, product evidence and technical information to learn what should change.
- Adapt the plan. Reorder, refine or stop work when new information changes the best next step.
- Improve the system of work. At regular intervals, discuss what helped or hindered the team and make a concrete adjustment.
This approach requires engineering discipline. Automated tests where appropriate, version control, security practices, documentation needed by users and regulators, and architectural work are compatible with Agile because they support a sustainable, working product.
Is Agile the same as Scrum?
No. Agile is the broader set of values and principles. Scrum is a specific framework designed to help people address complex work through defined accountabilities, events and artifacts. Scrum.org describes Scrum as an Agile framework and points to the Scrum Guide as its definition.

What are examples of Agile methodologies?
Terminology is not standardized across the industry. The Project Management Institute identifies Scrum, Scaled Agile Framework (SAFe) and Extreme Programming (XP) among widely used Agile approaches. They are examples, not interchangeable labels or a complete list.
Scrum
Scrum provides a compact framework for a team to create value in short, repeatable cycles and inspect results regularly. It is useful when a product problem is complex and priorities may change.
Rank #3
Extreme Programming
XP emphasizes engineering practices such as frequent integration, automated testing, close customer involvement and technical feedback. Its practices are intended to make changing requirements safer.

SAFe is an approach for coordinating Agile product development across larger groups. Its additional planning and coordination structures address scale, but they also add process and governance that smaller teams may not need.
Other team practices
Teams also combine Agile principles with approaches such as Kanban or a locally designed workflow. A board, daily meeting or iteration length does not by itself make a team Agile; the relevant question is whether the team delivers value, learns from evidence and changes its behavior when needed.
Is Agile only for software development?
Agile originated in software development. Scrum is also used in other complex domains, but transferring a framework does not guarantee the same practices or results. A hardware, marketing, research or operations team must account for its regulatory obligations, physical lead times, safety controls, dependencies and definition of a usable increment.
The underlying ideas—short feedback cycles, visible priorities, collaboration with stakeholders and regular improvement—can be useful outside software when the work genuinely benefits from inspection and adaptation.

When should a team use Agile?
Agile is a strong candidate when the team faces meaningful uncertainty and can obtain feedback during delivery.
Best Value
- Customer needs or market conditions are likely to change.
- A usable part of the outcome can be delivered before the whole initiative is complete.
- Customers or domain experts can review increments regularly.
- A stable, cross-functional team can make day-to-day decisions.
- The organization can measure outcomes and change priorities when evidence warrants it.
A different approach may be more suitable when requirements are fixed and fully knowable, change is prohibited by a tightly controlled contract, or work cannot be usefully inspected until a single final handoff. Even then, some Agile practices—frequent risk reviews, collaboration and retrospectives—may still help.
How to adopt Agile without creating a ritual-heavy process
- Define the product outcome. State who needs what and how you will know the outcome is valuable.
- Form a capable, cross-functional team. Include the skills needed to produce a usable increment, not just to write a plan.
- Make work visible and ordered. Keep one understandable list of options, decisions and current priorities.
- Choose a feedback cadence. Set a realistic interval for building, reviewing with stakeholders and deciding what comes next.
- Protect quality. Include testing, security, technical debt and documentation in the definition of finished work.
- Measure learning and outcomes. Look beyond activity counts; examine whether users receive value and whether important risks are shrinking.
- Change one improvement at a time. Use regular reflection to test specific changes instead of adding ceremonies without a purpose.
Common misconceptions and limitations
“Agile means no planning.”
Agile replaces the idea of a perfectly fixed long-range plan with planning at several horizons. Teams still estimate, sequence work, manage dependencies and make commitments; they revise those decisions when conditions change.
“Agile means no documentation.”
Documentation that supports users, operations, compliance, safety or future maintenance remains necessary. Agile favors documentation that is useful and timely over documents produced solely to demonstrate activity.

Neither the Manifesto nor the cited Scrum guidance establishes a universal success rate, cost reduction or speed improvement. Results depend on product uncertainty, team capability, technical constraints, leadership support and the quality of feedback.
“Installing a framework makes a team Agile.”
Adopting names, meetings or software tools without changing how decisions, quality and feedback work can create ceremony without adaptability. Framework fidelity and thoughtful inspection are more important than copying a checklist.
