The work inside a job
A job is a list of tasks. A tailor shop has seven. Hemming is folding and sewing the edge of cloth. Pressing is ironing cloth flat.
- No machine: 210 minutes of a person, 7 tasks.
- A machine can take four tasks: cut, stitch, hem, press.
- A person now only checks them. That is 58 minutes.
- A new task appears: care for the machine. Total 110 minutes, 8 tasks.
The rule
A machine can change the tasks in a job. Some shrink. Some stay. New ones can appear.
In this shop, measuring, billing and handing over stay the same. Billing is making the customer's bill. A person does these three tasks.
Cutting, stitching, hemming and pressing shrink. The machine does the work. A person checks it.
Care for the machine is a new task. It needs a new skill.
Add the minutes. Measuring takes 20, billing 10 and handing over 10. Together that is 40. Checking takes 58. Care for the machine takes 12. So 40 + 58 + 12 = 110.
| The day | Minutes of a person | Tasks |
|---|---|---|
| No machine | 210 | 7 |
| Machine does four tasks | 110 | 8 |
Fewer minutes of a person can mean less work for some people. People who learn the new tasks can keep working. Not every person will find that easy. Real jobs differ from this made-up shop.
Give tasks to the machine, one at a time.
