Last updated: October 2025

Discover what agile methodology is and how it shapes modern product development. Learn the key principles, benefits, and popular frameworks to help your team work smarter.

Agile methodology is a flexible approach to product and project management that focuses on adaptability and collaboration. Agile work is done in small, iterative cycles, which allows teams to respond quickly to change. Agile methodology prioritizes continuous feedback, teamwork, and improvement — so teams can build products that customers love.

Agile is more than a buzzword — it is a mindset that has transformed how folks build and deliver products. Agile methodologies and frameworks provide the structure and guidance that product teams need to deliver value fast.

But when people talk about being (or "going") agile, what do they really mean? Which agile methodology is best? Do all of the formal agile approaches adhere to the Manifesto for Agile Software Development, colloquially known as the Agile Manifesto? Can you call yourself agile without following a specific agile framework?

Merriam-Webster defines agile as "marked by ready ability to move with quick easy grace." Any product team would be happy to be described that way! And if we think about being agile as "quick easy grace," then we can more easily loosen the restrictions and process pedantry that you have likely heard about from agile purists. So to answer our last three questions above? It depends, not really, and sure.

With that in mind, every team must forge a unique path based on its market, how its organization operates, and what its customers need — regardless of the specific methodology, framework, or workflow it follows.

We cover quite a bit in the sections below. Even so, we only scratch the surface of one of the more hotly debated topics in product development. If you take away anything from this guide, we hope it is this: Agile is for rapid value delivery.
