Last weekend I was at the Amiga's 30th Anniversary event at the Computer History Museum here in Mountain View. A lot of the original Amiga engineers spoke. A couple of things stood out that are relevant here. First, the culture of the company was so positive, and what they built was so impactful, that even 30 years later, they considered it the highlight of their careers.
Second was that the engineers had offices with doors that closed.
As a programmer, I want to build solid, easy-to-use, impactful products that delight people. In order to do that I need to focus, and in order to focus I need long periods free of distraction. It's also satisfying to be able to get into a state of flow. I don't need that all the time, but I need and want it some of the time.
As a (hopefully!) future tech CEO, I want to work with people who want the same. As as Amiga Inc (and many others) have proved, small groups of people with private offices can produce wonderful things and still have a great corporate culture. I also want to make sure I spend my company's or my investors' money wisely and efficiently.
(As an aside, the reason that the Amiga had line-drawing built into hardware is because one of the software developers had experience with line-draw algorithms, recognized that it could be easily put into hardware, and convinced the hardware designer to do so. Which I offer as a counter to the people who think that private offices means people won't collaborate).
Finally, I'm rather taken aback that the director of a design agency would get onto a public forum and announce that he doesn't really care about productivity. Productivity relates to money spent; don't your customers care about how much it costs to engage you?
