Specialisation and division of labour — Economics, 7–10 years
People can make more or better things when each person focuses on a task and then shares the results.
One task each
A group often works faster when people divide a job into parts and each person practises one part. A baker may mix the dough while another person shapes it and someone else serves customers. Together, they make one result.
Why divide the work?
Long ago, people noticed that one person could not be quick at every part of making something. Repeating one task builds skill and saves time changing tools or methods. Division of labour solves this problem, but people still need to share fairly and understand the whole plan.
A sandwich shop
Mia alone needs 6 minutes to make one sandwich: 2 minutes for bread, 2 for filling and 2 for wrapping. With three people, each repeats one task and needs 2 minutes per sandwich. In 6 minutes, the team can make 3 sandwiches instead of 1, if the work is organised well.
The trap: faster is always better
It is tempting to think that dividing every job must always improve things. But a boring repeated task can make someone tired, and a team may stop learning other skills. If one part is badly done or nobody checks the result, the whole product can suffer.
Where you see it
You can see division of labour in a restaurant: one person takes orders, another cooks and another cleans tables. Hospitals, farms and factories also use different roles. It works best when the roles connect and people can speak up when something is not working.
