If I was to start a company that worked on a world-scale, the worst thing to form is an organic structured organization, in my opinion. A company working globally needs to have a rigid structure so everything can run smoothly and avoid a mess. Organic structures are more for smaller companies, I believe. According to the link given above, the best structure to imitate would be the Geographical Organization structure, since it obviously focuses on geographic locations to divide the company – by territories and regions. The disadvantage, as stated in the link, is the decentralization that occurs due to each territory running their section of the company. I would make sure this aspect is improved.
