What do employers seek when they are looking for groupings of collective skills and knowledge?

They are seeking collective thinking and knowledge for a faster turn around of work by the team in a whole. They want people to have different skill sets so they can share with each other.

Explanation:

By working together as a team, everyone can share their own direct knowledge they have picked up over their careers. Each person on the team will be able to share skills that they have learned and teach others. With everyone working together the job will get done faster and better than with just one person working alone on the job at hand.

The work environment of the team will have synergy and the working environment will be a collaborative effort.
