Agreed.

The high-end design firm IDEO specifically looks for "T-shaped people", by which they mean people who are deep in one area but have a broad set of skills outside their specialty. They believe that creative work is essentially collaborative, and that you can't be a great collaborator without a good understanding of what people are up to and the ability to step in and take a swing at anything that comes up, expert or not.

Another reason to avoid specialization comes, I'm told, from queuing theory. Unless your workload is perfectly regular, specialization leads to bottlenecking and global underutilization.

I'd also consider how Toyota, the world's #1 car company, looks at this. They do an immense amount of crosstraining, and line workers are specifically discouraged from specializing too much. Much of their efficiency comes from bottom-up innovation, which you don't get if people are focused only on their one little piece of the problem. (For more on this in particular, Toyota Kata is a great book.)
