The surgical team has limited size because of physical constraints - the software team does not have such a strict size limit. But we have seen that bigger teams get very very slow so we want small teams - so we look for ways to make the team smaller. It is useful to copy ideas from one domain to another one - it is called advanced analog field. For example the ABS system in breaks was developed for aircraft - but later someone observed that it would also be useful in cars even though they don't have the same operating constraints. http://web.mit.edu/evhippel/www/books/DI/Chapter10.pdf http://web.mit.edu/evhippel/www/books/DI/Chapter10.pdf
