I've worked with a bunch of development teams as a product manager and founder over the last decade or so. Whenever the team has come together with the rest of the company and collaborated to come up with a process that works for both them and the business, things have gone pretty smoothly, even though the processes themselves have varied widely from place to place. Whenever any party - developers, executives, product management - has tried to force a methodology without full discussion and buy-in from all parties, it's been a complete disaster. Because of this, I believe 'doing your job correctly' varies considerably from place to place, depending on the different people you happen to be doing your job with. Learning a specific development methodology is much less important than communicating and working with others to come up with a development methodology well-tailored to the context.
