Today, the Agile Alliance has nearly 30, members and subscribers. Meanwhile, agile methodologies continued to evolve. In the late s and early s, researchers from MIT had begun to study Japanese manufacturing systems, especially the Toyota production system. Although lean methodologies were not presented as agile frameworks in Snowbird, formal lean and kanban software-development systems emerged during the s.
At first, some agile purists refused to recognize these approaches as agile methodologies. But lean advocates intensified their focus on customer collaboration, and eventually more agile practitioners came to accept lean, kanban, and their hybrids such as scrumban and lean scrum as legitimate applications of agile values and principles. Success has many fathers, and agile innovation has a colorful heritage.

Hirotaka Takeuchi is a professor in the strategy unit of Harvard Business School. Those principles include:. The history of Agile came a long way during the February meeting in Snowbird, Utah, but the trajectory of Agile had still only just begun. Following that three-day meeting, the group of 17 leaders was ready for the next chapter in the history of Agile: Convincing the world of the value of everything they laid out in the Agile Manifesto. To help spread the word about the Agile Manifesto, the founding fathers in the story of the history of Agile decided to create a more permanent organization, and so the Agile Alliance was born.
The Agile Alliance is a nonprofit organization that still exists today. Following the creation of the alliance, the history of Agile took off in a big way, gaining traction with software development teams throughout the early s. As Agile took off, the role of the Agile Alliance expanded. In , the now-formal Agile Alliance returned to Utah for the first annual Agile conference — an important milestone in the history of Agile.
The Agile Alliance has also expanded geographically over the years. Today, the Agile Alliance supports affiliate groups all over the world that promote Agile in local markets and help nearby organizations adopt the Agile Manifesto. While Agile took off in the early s, we saw the Agile Manifesto pick up new steam in the s.
By this time, the history of Agile was a commonly recounted story among development teams, but between and , real life success metrics began to accompany that story. As a result of the ability to demonstrate success in Agile at that point, the benefits of adopting the lightweight methodology became undeniable.
Shortly thereafter, Agile began to explode, this time by moving beyond development. In , we saw the first succinct definition of Agile Testing. This definition outlined collaborative testing activities focused on frequent delivery of quality products that prioritize defect prevention over defect detection. As of , we see near ubiquitous adoption of Agile in some sense across development teams, particularly those in the software industry.
It also brings us back to the earliest parts of the history of agile and the problems development teams faced with the waterfall methodology. This situation begs the question: Can the Agile Manifesto stand the test of time? Today, we hear a lot about DevOps, or the idea of creating a continuous loop of delivery in which new software can go to market at any time and is always ready for production. DevOps is the latest iteration of the idea that high quality products should be delivered to users as quickly as possible and then improved upon on a regular basis.
Currently, we see teams embracing Agile and DevOps hand-in-hand, and we can likely expect this trend to continue for the next several years. Along the way, Agile has evolved to meet changing needs, but it still stays true to that initial manifesto. If we can expect nothing else, we can be sure that Agile will continue to evolve, embracing its own core values and principles to remain a ubiquitous approach among development teams in the software world and beyond, even as their needs change.
While major and highly visible projects often used a strict waterfall model, alternatives were lurking in the background. At the same time, more specific iterative methodologies were being developed. For example, Jeff Sutherland and Ken Schwaber conceived the scrum process in the early s. The term came from rugby and referred to a team working toward a common goal.
They codified scrum in in order to present it at an object-oriented conference in Austin, Texas. Scrum was based on the concept that for the development of new, complex products, the best results occur when small and self-organizing teams are given objectives rather than specific assignments. The team had the freedom to determine the best way of meeting those objectives.
Scrum also defined time-boxed iterative development cycles whose goal was to deliver working software. Today, most teams that claim to practice an agile methodology say they're using scrum. At around the same time, Kent Beck was hired as a consultant on an experimental software development project at Chrysler.
In time, he was named the project leader, and in an effort to succeed was determined to take best practices to an extreme level, giving the XP methodology its name. While the project was ultimately cancelled when Chrysler was acquired, Beck had published a book titled Extreme Programming Explained , and his name became synonymous with one of the leading alternative methodologies.
Perhaps various agile and iterative techniques would still be in the minority were it not for the Agile Manifesto, codified at that meeting in Snowbird. Despite the uncertain goals of this group, the Manifesto is the clearest and most succinct statement of purpose of an approach that was the antithesis of the waterfall model that was still prevalent at the time.
As a result, the software development community has latched onto the Agile Manifesto and its 12 principles as the definitive statement of the agile software development movement.
Today, more and more teams self-identify as using an agile methodology. While many of those teams are likely using a hybrid model that includes elements of several agile methodologies as well as waterfall, that they identify so completely with the agile movement is a testament to both the strength of the statement and the power of the movement.
And while agility got us to where we are, it's not the end of the story. There is life beyond agile, though agile was a necessary first step to see where software development might be able to venture.
It may be foolish to demand a software change as quickly as our minds can see the need, but it isn't foolish to try speeding things up. Can agile concepts promote continuous, effective change in our software? Can we get to the point where a software "release," with all its improvements, is no longer an event to be planned for, but simply a daily, hourly, or minute-to-minute occurence like breathing? He gave this one-hour talk without ever once mentioning agile. But there was no question as to what he was describing.
He phrased it in terms of the trend toward releasing software to production more quickly, and discussed what it meant to be able to release new versions quarterly, monthly, weekly, and ultimately daily or even continuously. Agile processes are a necessary first step in that direction, but continuous delivery requires even more radical change. It means that developers try something based on their best knowledge at the time yet are fully prepared to remove or change it immediately based on user reaction.
And user reaction doesn't come in the form of words but rather in the form of actions. We monitor the application in production and collect data on user behavior.
Real-time analysis of that data tells the team what to do next. And what happens next will take no more than a day or two. Take a deep dive into the state of quality with TechBeacon's Guide.

To agility and beyond: The history—and legacy—of agile development. First came the crisis In the early s, as PC computing began to proliferate in the enterprise, software development faced a crisis. Thought leaders were frustrated Jon Kern, an aerospace engineer in the s, became increasingly frustrated with these long lead times and with the decisions made early in a project that couldn't be changed later.
And agile was born These frustrations around seemingly unproductive software development activities, which were shared by like-minded professionals, led to the now-famous Snowbird meeting in Utah in early
