HR loves open office, but the genesis of the idea was silicon valley where startups rented huge warehouses in which people could move between a number of creative work space options and their tasks changed. Where it always fails in corporate settings is that management also wants to save money so it packs as many rats in the cage as it can fit. Sheets of continuous desks and low height cubes always fell like working in an airport (with all the associated distractions) and high wall cubes lead to a prairie dog towns with works hunkered in their burrows until some sounds causes all the dogs to pop up for a look. The whole open office concept appeals to HR types because their jobs are all about interactions, meetings, and quick task flips. Ask any technical worker, who needs to really focus on hard tasks, and you will find universal unhappiness with an open office setup. Last I looked, however, the real value creators in Chevron offices are the more technical workers (and obviously those that do hands on work in the field). The rest are just support staff, which begs the question as to why management continues to optimize the tail waging the dog instead of letting the big dogs run.
