Agile Development

An in-depth look at the different ways to be agile.

Agile is a conceptual framework that promotes incremental, well-planned iterations throughout the development cycle.

Adopted from old-school manufacturing principles, lean aims for quality, speed, customer satisfaction, and a reduction of waste.

Waterfall assumes that the entire concept is conceptualized at the start of a project, and doesn't account for much feedback.

Scrum adherents consider it continuous, iterative, and incremental, a process executed by one cross-functional team.

Kanban provides a more visual representation of where workstreams are and, ultimately, where bottlenecks are.

With its focus on small projects, proponents of XP say it improves the software-development process through collaboration.
