You can’t avoid the term “Agile” if you try. From CIO to HBR, some of management’s most influential websites are teaching readers how to build the basics. The BBC even called Agile “the new boardroom buzzword” earlier this year.

It’s true that Agile is getting more mainstream. Today’s digital projects move and change so quickly that businesses have no choice but to take the ride. But Agile is far from a new concept: project managers have used it for years.

Understanding Agile

The Agile methodology stems from software development. In February 2011, 17 developers met in Utah to find common ground in the ways they worked. They were using a wide range of software development methods, from Scrum and Extreme Programming to Adaptive Software and Feature-Driven Development.

By the end of their trip, all attendees had written and signed a Manifesto for Agile Software Development. You can read the full Agile Manifesto here.

This group called themselves the Agile Alliance and vowed to help developers work more efficiently via smaller, more frequent development cycles. But they also realized that their goal to help teams work more efficiently didn’t just apply to software.

The Agile Manifesto’s founders believed that this framework could help teams of all types who wanted to achieve more in less time. Sure enough, the rise of doing business online in subsequent years impacted project management.

Project teams became expected to do more than finish projects on time and under budget. Instead, they were expected to achieve these more quickly and contribute to business strategy. As a result, project managers needed new tools and methods to help their teams reach these goals.

Experts for Agile project managers

Agile has become more mainstream due in part to experts who freely share their insights. Many members of the first Agile Alliance actively blog and teach around the world. They also share expertise with the world on Twitter.

Whether you’re new to this space or an Agile veteran, these influencers are worth following. Name recognition wasn’t enough to earn a spot on this list. At GetApp, we wanted to honor Agile leaders who use their influence to educate the public. We also chose influencers who share how Agile is used in a wide range of ways, from project delivery to traditional management.

This list isn’t exhaustive, so make sure to share your favorite Agile influencers at the end. In the meantime, read on to see who made our list:

If Kent Beck is the godfather of Agile, Robert Martin is the method’s uncle. Self-professed “Uncle Bob” called the meeting that produced the Agile Manifesto. In doing so, he helped usher the movement away from Extreme Programming techniques.
