Pyramid of Success 

Cooperation

"With all levels of Your co-workers. Listen If you want to be heard. Be interested in finding the best way, not in having your own way."

Cooperation is the key to success in many ways, like for an example your working with your friend in a job or somebody that your co worker and you both have to install some components into a machinery and that piece of machinery is really huge and both of you have to be communicating with each other and making sure that each new installed components are showing up in the computer making sure that every thing is placed correctly and not making a fatal error in doing so. So both of you have to talk to each other making sure that every thing is in the all clear zone. So with all that being said for an example now you have clear example of what working with each other or group of members, so with all being said " Team work makes the dream work."
