In this video on InfoQ, Ron Jeffries talk about agile software development. What is worth pointing out is how he emphasises the similarities between the different agile methods. One difference between how Ron explains things, and how Ken Schwaber does it, though, lies in the graphing of the growth of features. When Ken draws the line, it starts out growing slowly, indicating more focus on “architecture” early on (but still producing features every sprint). When Ron draws the line, it is more linear, indicating his desire to have a more constant growth of features with a really evolutionary approach to “architecture”.
