This is also not very interesting question. It was recognized ages ago that mechanical, manual labor, such as assembly line or McDonald's , should be organized in an open-space, while thinkers must have their private comfort zones (which is very expensive) and occasionally meet in a small groups to share ideas. The balance is quite subtle, as usual. So-called brain-storming sessions (which in the language of normal people is called a discussion group) could be very effective (only if participants have something to be stormed) while meeting of committees of idiots is always a disaster. The first activity is centered around subjects and goals, while the second is dedicated to the action itself and a sense of self-importance. In other words, for those who think of software development as an assembly line (which is very wrong) mass-production best practices are quite appropriate, while others, who think of it as a process of writing poetry, the best practices appropriate for a writers and thinkers should be considered. Unfortunately, idiots dominate the world.
