When you ask a vendor if their software works, you don’t want them to respond with “In theory…” However, the website theitriskmanager points out that’s what they should say if the only people that know about the product are the trainers and consultants selling it.
The drive behind the Agile Revolution was to give the people software that wasn’t just based on some theory developed in University or IBM labs, but to take a learning approach and sell the product only once it had been tested and refined.
the blog post goes on, explaining how the author feels that Agile might now be steering away from their high standards with the promotion of SAFE, a framework for scaling Agile. How do we know that SAFE works? We don’t. Those that buy it are just testing a theory. As an enterprise wide framework, SAFE could take years to implement and even longer to analyze the success. In short, no one knows how it will play out just yet, even the vendors selling the product. Before purchasing, do your research, and make sure you are buying something that works in practice instead of in theory.
