Definition
Agile Methodology is an iterative and incremental approach to project management and software development that emphasizes continuous delivery, customer feedback, and flexible response to change. It was formalized in the Manifesto for Agile Software Development (2001), prioritizing “individuals and interactions over processes and tools” and “responding to change over following a plan.”
Why It Matters
In a rapidly changing world, the “Waterfall” approach of fixed, long-term planning is a recipe for building products that are obsolete before they ship. Agile provides the “course-correction” mechanism required to align development with reality through continuous feedback and iterative growth.
Core Concepts
- Iterative Development: Breaking work into small, manageable chunks (Sprints or Cycles) that produce a working product increment at the end of each period.
- Empirical Process Control: Relying on transparency, inspection, and adaptation rather than upfront predictive planning.
- Cross-Functional Teams: Empowering self-organizing teams that contain all the skills (design, dev, test) necessary to deliver value.
- Continuous Feedback: Frequently engaging with stakeholders to validate assumptions and adjust the product roadmap.
- Kanban and Scrum: Common frameworks used to implement Agile. Kanban focuses on flow and WIP (Work in Progress) limits, while Scrum uses time-boxed events and defined roles.
