I currently work in a matrix style organization. I think it fits me the best, and if I founded a company that is the way I would run it. The biggest benefit in my eyes is the ease of access to knowledge and information. I work in product development, but if I have a question about the packaging or manufacturing of the product then I can quickly go to the subject matter expert. The area of product development I work in is different from regular PD, so it leads to me working with the same people often. This has allowed me to develop a better relationship with them so that projects can be expedited if need be. Matrix style offers a sort of best of both worlds combining good parts of functional and project based organizations.
