Want to be more 'agile'?

That's been the buzzword in IT and the software business for the past 20 years.

Two papers that give answers -

Is it really that effective? My overall impression is that it's basically prototyping as if you one was in a startup with just the investor and developer. So for small groups who have yet to discover what their business is (because they are creating something new), or their business and customers is evolving, it can work.

Does it actually work in larger corporations with customers that oftentimes are both distributed around the globe, and even more so, have different even conflicting needs?

Often times, I'd say the answer is no.
