It's good to see David Mandala has arrived here at Advogato. I can't wait to read his diary entries.
org charts: for a company that does open source professional services, specializing in integration and support. Take groups of about 4-6 employees. The group will have a focus, like the Mac integration experts, or the Alpha people, etc. Each group will have a technical lead. The group will be responsible for a project from beginning to end. Meaning that the group will evaluate the business need for integration of open source into the current environment, architect possible solutions, implement the appropriate solution, and support that through the contract. Employees who wish to apprentice themselves to group with another focus, would first transfer their knowledge to a more junior member of their own team. Then, after they switch groups, they may act as a consultant for their former group. I see maybe 4 - 5 of these groups all having a manager type work with them to track projects, and employee well-being, budgets, etc. Any given job could require one or more groups to work on it. This is, of course, a very loose sketch.
