Today at Oticon, teams form, disband, and form again as the work requires. The company has a hundred or so projects at any one time, and most people work on several projects at once. It is, essentially, a free market in work. We allow a lot of freedom. We don't worry if we use more resources than planned.
Deadlines are what really matter.
The company's physical space reflects its logic of work. All vestiges of hierarchy have disappeared. It's an environment that maximizes walking, talking, and acting. If you can't talk to someone because he's sitting behind a secretary and a potted plant, he'll never know what you know. People need to move around.
