You know what the great irony in all of the "agile methologies" is? Lean manufacturing is almost always about process improvement. Going back and looking at your process and finding ways you can make it better, faster, cheaper, more reliable, etc. Kanban IS the new Scrum insomuch as it's the latest buzzword, but any agile process should be in itself "agile". As in, it's about shipping using the best possible process for your situation. Maybe that's scrum, or kanban, or waterfall, or something in between. If you are using any of them you should ask what problem you have with your current process and what you are solving by doing scrum, xp, kanban, etc. Dit it work? Can it be done better? What needs to be fixed? Iterate enough on your process and you'll be running like a well oiled machine regardless of what method you use. People get good at stuff with practice. Where it goes wrong I think is when you worry more about scrum vs. kanban vs. xp vs. flavor of the week because the rules don't matter, doing your work better for whatever definition of better you're optimizing for is what truly matters.
