Why do developers like Agile?

Developers embraced Agile in response to project methodologies like Waterfall, which was borrowed from low variance industrial production. Whilst waterfall worked well when producing many of the same thing, in development, where there is much uncertainty and a need to adjust course often.

Agile embraces the idea that the future is uncertain, and rather than build long project gantt charts that show a false narrative of certainty, it is more efficient to acknowledge this and break work up into epics and sprints.

There is a counter movement however to Agile, where some developers reject the rigidity of formal agile projects where project managers are essentially appearing as scrum masters or where there is too much rigidity in the processes which is the antithesis of "Being Agile".

So in summary, whilst developers like Agile generally, it should be acknowledged that most developers like "Being Agile" rather than a strict "Agile Project" approach.
