I have some of the greatest managers and colleagues I have ever had in my working life. Yet one thing that seems to be highly enforced at our company are workplace silos, i.e. information should not flow between different teams/departments unless the managers want it to.
Most business and management books/articles/blogs seem to demonize the workplace silos... but since we are a very successful company (market leader) and have some very qualified staff, I imagine that there can be situations where it might be beneficial and productive to the company's purpose.
I am personally not offended by the silos, but would simply like to understand what drives and motivates their existence.
An example reason that comes to my mind is: a very new strategy that shouldn't be leaked anywhere, and thus is held secret even to internal staff.
