Teams adopt Agile frameworks to structure principles into daily work, choosing tools that solve specific challenges like speed, scale, or quality. Scrum is the most popular, using fixed-length Sprints for predictable delivery in small to medium teams. Its structured roles and events provide cadence but can feel rigid if applied mechanically.

For continuous flow, Kanban visualizes work and limits Work In Progress (WIP), ideal for DevOps and support teams facing shifting priorities. It's flexible but lacks built-in planning. SAFe scales Agile for large enterprises through Agile Release Trains and Program Increment planning, offering alignment at the cost of heavier process.

Extreme Programming (XP) prioritizes engineering excellence with practices like Test Driven Development (TDD) and Pair Programming. Lean Software Development focuses on eliminating waste, adapted from Toyota. Niche options include Crystal for small teams and DSDM for fixed-budget projects, each balancing structure with adaptability.
