In my recent experience I worked for both matrix and functional organization structures. I found that functional organizational structures much more efficient than matrix organization structure. I am not saying matrix structures do not work, but communication was very difficult. In some cases we had to set more meetings just to going over and explaining our work, and what is the next plan moving forward. I agree, transparency between departments is very beneficial no matter with what structure, but I think that’s the most difficult part. Communication was a lot difficult in a matrix organization structure.
