Hello, For over two decades now, proponents of Agile have had to contend with the myth that “you can’t use Agile for X,” where X represents high-assurance systems, systems subject to rigorous regulatory requirements, cyber-physical systems, systems with known and fixed requirements, systems for national defense and security, big data systems, and so on. I’ve been around long enough to have a sense of why these perceptions arise, so I always respond by simplifying Agile.
