Productivity and production methods

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

How a business combines people and machines affects how much it can produce and at what cost.

Labour and capital intensive

Labour-intensive: uses a high proportion of workers compared with machines, such as hand-made furniture or hairdressing. Flexible but higher labour costs.
Capital-intensive: uses a high proportion of machinery, such as car assembly with robots. High output and low unit costs, but expensive to set up.

Productivity

Productivity = output ÷ number of workers (for a given time period).
Higher productivity means lower cost per unit, more competitive prices and possibly higher wages.
It can be improved by training, better equipment, better motivation and better methods.

Technology and robotics

Robots work continuously, accurately and in dangerous conditions.
But they are expensive to buy and maintain, can replace jobs, and are less flexible.
Businesses must balance cost, productivity, quality and flexibility.
Worked example

A factory makes 6000 units a week with 40 workers. After training, 40 workers make 7200 units. By how much has productivity per worker risen?

  1. Before: 6000 ÷ 40 = 150
  2. After: 7200 ÷ 40 = 180
  3. 180 − 150

Answer: 30 units per worker per week

Key idea

Labour-intensive uses mostly people; capital-intensive uses mostly machines. Productivity = output ÷ workers. Higher productivity lowers unit costs. Robots raise output and accuracy but are costly and inflexible.
