Scrum and XP are New - Their Principles are Not

If history repeats itself, the software development methodologies of the future will include ideas that are rediscovered in older work models. Today, many of the "new" methodologies consist of repackaged and reconfigured elements from methods that were used a long time ago. Scrum is a good example because it contains many core practices of from agile, but renames many of them. Kniberg talked with Jeff Sutherland, the co-creator of Scrum, who said there wasn't any commercial motivation behind his rebranding of old ideas into a new methodology. "He was just trying to find something to make his company work better," said Kniberg. "He looked at a whole bunch of case studies to find out why projects fail or succeed - and he picked out the best bits." Sutherland found out that projects usually succeed when they have daily meetings and close contact with the customer. Putting these, and other patterns together formed the basis of Scrum. Ken Schwaber, the other founder of Scrum, believed that Sutherland's method could be configured to work with other companies. The two founders named their methodology "Scrum" and rebranded agile elements using Rugby terms to emphasize teamwork.
"Packaging is important," says Kniberg. "Even though the ideas aren't new, choosing the right subset of maybe hundreds of patterns seems to have an immense power." Kniberg says the ideas behind Scrum and XP aren't "new", but they've become very popular because they provide open systems that generally work well for many organizations. "[Scrum or XP] will bring any company from a dysfunctional state to a fairly functional state, but it won't bring them to Nirvana," said Kniberg.
At some point, companies need to star thinking and configuring on their own, but Kniberg says that Scrum and XP can boost them to a decent level of process maturity. "In an ideal case, everyone would be smart enough to just do whatever is right, and we wouldn't need any named methods, but people aren't process experts. These packagings that are well thought out help a lot." Now, Kniberg says, agile methods like Scrum and XP have launched companies to a higher level of maturity, and that might be what's causing new discussions about Lean/Kanban. "I think people have made the same journey as me, and asked themselves, 'This seems to work, I wonder why?' And then they start digging and they find these older sciences like Theory of Constraints, Lean thinking, and queueing theory behind their method that explain why it works," said Kniberg. Many tools have grown out of older principles like the ones Kniberg mentioned. GTD (Getting Things Done), David Allen's method for personal productivity is one tool, said Kniberg. Another is Francesco Cirillo's Pomodoro Technique for time management. Kniberg says that systems like Scrum and XP exist as tools for applying proven, generic principles to a practical work environment.
Kniberg believes that the regeneration of old ideas in the form of new methodologies is a natural, never-ending process." I think we need to stop expecting that things have to be new in order to be good, said Kniberg. "It's okay to rediscover old knowledge - it happens all the time. Software development boils down to communication and communication is old."
