I’m working with a number of companies using agile methods that have between 10 and 20 teams all working on the same product/project/program. They didn’t start small. These aren’t cases of organically growing from one good agile team to many good agile teams. Rather, these are organizations that have grown up in a non-agile approach and now want to reap the benefits of agile with their many teams. What is interesting is that these organizations all have some common problems and then all have some unique problems. There isn’t an obvious prescription for how they should be doing their agile implementations. I hope to write a few articles about scaling agile and scrum, and this one is our starting point: what reading should you do if you find yourself in the situation of trying to build a large agile organization.
