Mexico is, by its nature, a relationship driven culture and therefore Mexicans will work extremely well in a team situation so long as the members of the team have a good relationship with one another.
However, it may take a while for people to form these solid relationships if they are new to each other. (In some other cultures, it is possible to bring a group of strangers together and expect them to meld quickly into a good team provided the goals are clearly set.) In Mexico relationship building can be a lengthy business and teams can take a while to bond.
Once teams are formed and relationships set, it is best to leave the group intact and move them en masse on to the next project, rather than dismantling the team and starting a new team from scratch.
