The amount of output produced or the number of customers served
productivity
Measures the output compared to the inputs/resources used. For examples, labour productivity measures the amount of output produced by workers over a period of time. (= output/ number of employees)
efficiency
Refers to how well resources are used to produce products with minimum waste and low cost
inventory
Can consist of raw materials, components, parts, work-in-progress, and finished goods
lean production
A Japanese philosophy of production that tries to improve efficiency by reducing time, waste, resources and labour time in the production process
Two of the key elements in this are just-in-time stock control and Kaizen (continuous improvement)
just-in-time (JIT) inventory control
Involves holding minimal level of stock and arranging deliveries so that orders arrive just as they are needed in the production process
Kaizen
Means continual improvement and involves making small incremental improvements in the production process, often based on ideas from the workforce
job production
Involves making each product individually to the specific requirements of the customer. E.g. a tailor-made suit
batch production
Involves producing small quantities of identical products at the same time in a group or batch. E.g. bakery products
flow production
Involves large scale production of identical products along a continuous production line, which is often automated. E.g. electronic goods
fixed costs (FC)
Costs that do not change with the level of output. E.g. rent
variable costs (VC)
Costs which change directly in line with output. E.g. raw materials
average costs (AC)
The costs of producing one unit of output (= total costs / output)
total costs (TC)
The total sum of all the costs involved in the business (= fixed costs + variable costs)
economies of scale
The cost benefits and efficiencies of large-scale production which lead to lower unit costs (average costs)
purchasing economies
When buying in large quantities discounts can often be negotiated which reduces the unit costs (costs per item)
marketing economies
Many marketing costs (such as adverting on TV) are fixed costs. When spread over a larger output or number of customers these costs are shared and unit costs fall
financial economies
Larger businesses have a access to a greater range of sources of finance and can negotiate better terms and lower interest rates, leading to lower unit costs
managerial economies
Larger businesses can afford to employ specialist managers who are expert in their particular field, leading to greater efficiency and better decision-making, leading to lower unit costs
technical economies
Larger businesses can afford to invest in better technology and machinery which increases productivity and reduces waste, leading to lower unit costs
diseconomies of scale
The cost disadvantages and inefficiencies of large-scale production, which lead to higher unit costs (average costs)
break-even output
The level of output at which total costs are exactly matched by total revenue and the business makes neither a profit nor a loss
margin of safety
The difference between the actual level of output and the break-even point
quality control
Where a product is checked at the end of a production process
quality assurance
Involves self-checking throughout the production process by all employees to prevent mistakes from happening
Production
The effective management of resources in producing goods and services
Operations department
Oversees the production process
Use resources in a cost-effective and efficient manner
Manage inventory effectively
Produce the required output to meet customer demands
Meet the quality standards expected by customers
Productivity
A measure of the efficiency of inputs used in the production process over a period of time
Labour productivity
The output measured against the inputs used to produce it
Increasing productivity
Output increases per employee, average costs of production fall, able to sell more and lower prices
Ways to increase productivity
Improving labour skills through training
Introducing automation
Improving employee motivation
Improving quality control and assurance
Inventory
Stocks of raw materials, work-in-progress, and finished unsold goods
Reorder level
The point at which inventory is reordered to bring the level back up to the maximum
Lead time
The time it takes for the reorder supply to arrive
Buffer inventory level
The minimum level of inventory the business should hold to satisfy customer demand at all times
Lean production
Techniques to reduce wastage and increase efficiency/productivity
Seven types of wastage
Overproduction
Waiting
Transportation
Unnecessary inventory
Motion
Over-processing
Defects
Benefits of avoiding wastage
Less storage of raw materials, components and finished goods
Quicker production of goods and services
No need to repair faulty goods
Costs will lower, making the business more competitive and earn higher profits
Kaizen
A Japanese term meaning 'continuous improvement', aims to increase efficiency and reduce wastage
Just-in-Time inventory control
Eliminates the need to hold any kind of inventory by ensuring that supplies arrive just in time they are needed for production
