3.1 - Production & Productivity
The meaning of production and its key elements
Production refers to the process of creating goods or services for sale. It transforms various resources into items that customers can buy.
Inputs used in production
Production relies on converting inputs into outputs.
These inputs come from the four factors of production:
- Land - Natural resources like raw materials or physical space.
- Labour - The workforce, including skills and effort from employees.
- Capital - Tools, machinery, and equipment used in the process.
- Enterprise - The organisation and risk-taking by business owners to combine the other factors.
Inputs can also be classified as:
- Tangible - Physical items that can be touched, such as machinery or raw materials.
- Intangible - Non-physical elements, like innovative ideas, specialised knowledge, or employee talent.
Outputs created through production
The end results of production are outputs, which must have exchangeable value to be sold in the market. These could be physical goods, like clothing or electronics, or services, such as repairs or consultations.
The concept of productivity and how it measures efficiency
Productivity measures how effectively a business or economy turns inputs into outputs. It indicates efficiency by showing how much is produced relative to the resources used.
Productivity is calculated as the output per unit of input. For example, if two firms use the same resources but one generates more goods, it has higher productivity. This can be assessed overall, using all inputs combined, or for individual factors of production. Improving productivity in any single factor, such as better use of machinery, typically boosts the overall level.
Labour productivity and its calculation
Labour productivity focuses on the efficiency of the workforce, one specific factor of production. It measures how much output is generated by each employee or per hour of work.
Formula for labour productivity
Where:
- Total output = Quantity of goods or services produced in a given period
- Total number of workers = Number of employees involved
- Total hours worked = Combined hours from all employees
This calculation allows comparisons between individual workers, teams, or entire national workforces.
Worked example - Calculating labour productivity
A workshop produces 2,500 shirts in a month. During this time, 20 workers each complete 50 hours of work. Calculate the labour productivity per worker and per hour worked.
Step 1: Identify the values
- Total output = 2,500 shirts
- Total number of workers = 20
- Total hours worked = 20 × 50 = 1,000 hours
Step 2: Calculate productivity per worker
Step 3: Calculate productivity per hour
Ways to improve labour productivity
Enhancing labour productivity leads to greater efficiency, allowing businesses to produce more with the same workforce. Several strategies can achieve this.
Methods to increase labour productivity
- Better training - Equipping workers with new skills through courses or workshops, enabling them to work faster and with fewer errors.
- Gaining more experience - As employees perform tasks repeatedly, they become quicker and more proficient over time.
- Improved technology - Introducing tools or software that automate parts of the job, reducing manual effort and increasing output.
- Specialisation - Assigning workers to specific tasks they excel at or have practised extensively, rather than switching between varied roles. This focuses their efforts, boosting overall production compared to a generalist approach.
