Complicated or complex products need good cross-functional coordination to make the product as robust as possible. Cross-functional teams that have all the skills on board to deliver their contribution “ready to use” with as few interfaces as possible are the best help here.

But complex projects also need the speed and throughput in the implementation of large tasks that often only a group of experts can provide. Therefore, it is also necessary to well integrate the groups of experts that simply “do away” with large mountains of work. For example, software teams producing millions of lines of code, or electronics engineers designing complex circuit boards.
