Nice article. I'd suggest for anyone making the transition into management (particularly from a more technical background) who is after some concrete advice - start by reading 'High Output Management', and getting a subscription to Manager Tools. In terms of the article, I'm not sure I would use the term 'senior' to apply to a manager (or individual contributor), until they are at the 10-15 year experience level (which may come in much more or less than 10-15 years employment based on circumstances).
