In my current company, the organization type is a mix between functional and a project based organization. There are individual departments ranging from Hardware Eng, Quality, Software Eng, Systems Eng, Marketing, and Manufacturing. There certainly are silos, but for those of us in the R&D group that are not working on the on market product, there are projects where those of us from different groups come together. For example, we are currently writing protocols for 510k submissions and I work with engineers from the software, hardware, and the quality department (basically those in the R&D group). I do not mind the set up because I mainly deal with the different engineers in the research and development group, and I have also had some conversations with those working on the on-market product. I think this setup of structure works mainly due to its size, where there are about 200 employees, so everybody interacts with one another at one point.
