I believe the matrix org structure would be the best for most companies. It provides a well balanced structure as the employees have to report to at least two bosses; their functional manager and product manager. This helps a company share resources and provide a unified environment. However, for a medical device company worldwide, I believe the divisional: geographical org structure would be the best. This is ideal when different countries have a different target market, different restrictions, and different resources. Sharing resources could be difficult when divisions are on opposite sides of the world, so a geographical org structure helps to accommodate each division by their location. The major downfall is that the decision making can be easily decentralized but I believe its benefits out way this risk.
