Microsoft Is Reorganising The Company Structure

Microsoft:

This means we will organize the company by function: Engineering (including supply chain and datacenters), Marketing, Business Development and Evangelism, Advanced Strategy and Research, Finance, HR, Legal, and COO (including field, support, commercial operations and IT). Each discipline will help drive our overall strategy. Each discipline will also be charged with improving our core capabilities in its area. We must improve in all aspects of the business.

They are changing to a structure very similar to what Cook is doing at Apple, splitting departments cleanly by function, one person atop each.
