History of Agile -- edited

ASSESSING LEARNING

In 1957, people started figuring out new ways to build computer programs. They wanted to make the process better over time, so they came up with iterative and incremental methods.
In the 1970s, people started using adaptive software development and evolutionary project management. This means they were adjusting and evolving how they built software.
In 1990s, there was a big change. Some people didn't like the strict and super-planned ways of doing things in software development. They called these old ways "waterfall." So, in response, lighter and more flexible methods showed up.
