I mean everything. Almost literally everything.

The most recent thing I can think of is seating arrangements.

At my current workplace seating arrangements are mostly random. Someone here had the idea that we should group people by seniority so that people with related issues will be in close proximity.

However, at my previous workplace we grouped by seniority, and someone had the idea that we should mix it up so that project teams would be in close proximity.

[edit]: And lets not forget outsourcing vs. insourcing, grouping departments by geography vs. grouping departments by business type, etc., etc.
