Craft specialization is the term archaeologists assign to that point in development where a society is made of members who each fill a specific gap within the community to keep the community as a whole functioning. In a society that has reached this milestone, community members not only fulfill their role and continue their practice, they also support other community members in doing the same.
But it doesn’t just stop at these ancient communities. We sometimes run into something similar in our school and work teams. I once led a school project team that had organized itself. Half the team had research skills, so they tackled all of the research and writing . The other half had presentation skills, so they handled that. I was stuck in the middle coordinating both teams’ work to make sure we had a great project. Because everyone was able to contribute their strengths, we aced the project. If more teams were able to organize by complementary strengths (rather than by random choice, as so often happens in school), it would allow each person to find their place within their community/team, direct their own growth and professional development according to their interests (including both their learning and reviewing of skills, concepts, processes, and procedures).
By being aware of whose skills and interests complement your own, you can then build stronger teams to focus on projects and problems, who can not only create a better product but can also help encourage each other to grow stronger in their specific sphere because it benefits the team. It alleviates the need for competition because the community as a whole needs everyone to be the best they can possibly be.
