What is Agile Methodology?
Agile methodology is an iterative approach to project management and software development that emphasizes flexibility, collaboration, and continuous delivery of working increments. It breaks projects into short cycles called sprints, enabling teams to adapt to changing requirements and deliver value to users incrementally.
Agile emerged as a response to traditional "waterfall" development, where requirements were fully defined upfront, and the entire product was built before any testing with users. Agile reverses this: define a small scope, build it quickly (in 1-4 week sprints), test with real users, learn, and repeat. The Agile Manifesto prioritizes individuals and interactions, working software, customer collaboration, and responding to change.
Common Agile frameworks include Scrum (with roles like Product Owner, Scrum Master, and structured ceremonies like sprint planning, daily standups, and retrospectives), Kanban (continuous flow with visual work-in-progress limits), and SAFe (Scaled Agile Framework for large organizations). Each has specific practices suited to different team sizes and contexts.
In case interviews, Agile concepts appear in technology, product development, and organizational transformation cases. Understanding Agile is important because many companies undergo Agile transformations—shifting from waterfall to iterative development affects team structure, budgeting, vendor management, and performance measurement.
Real-world example
ING Bank's Agile transformation reorganized 3,500 employees from functional silos into 350 cross-functional "squads" of 9 people. Time-to-market for new features dropped from months to weeks, and employee engagement scores increased by 20%.
