2.4.1 Flashcards
Production, Productivity and Efficiency
What is job production?
○ Only one product is produced at a time
○ Used when orders for products are small
○Examples: Baking cakes, Crossrail
Benefits of job production?
○ Quality of production is high
○ Varied work means workers are more motivated
○ Products can be custom made more easily
Negatives of job production?
○ Higher labour costs
○ Production times may be slower
○ Generally this is an expensive method of production
What is batch production?
○ Used when demand for a product is regular
○ Example: Furniture
○ Production is carried out in operations, the same process is done to the entire batch at the same time
Benefits of batch production?
○ Workers specialise in one operation of the production
○ Unit costs are lower because of a higher output
○ Production is flexible as different orders can be met
Negatives of batch production?
○ Careful planning and co-ordination is required
○ If batches are only small, unit costs can still be high
○ Money can be tied up in work-in-progress
What is flow production?
○ Different operations are carried out one after the other in a continuous sequence
operation to the next along a conveyer belt
○ Uses a semi-skilled workforce only specialising in one operation of production
○ Large amount of machinery and equipment are used
○ Large stocks of raw materials and compound are used
○ Examples: Newspapers, food, cement, cars etc
Benefits of flow production?
○ Very low unit costs due to the economy of scale
○ Output can be produced very quickly
○ Modern machines can allow for more flexibility
○ Production speed can be varied according to the current demand
Negatives of flow production?
○ Products may be too standardised
○ Huge set-up costs have to be incurred before production can even begin
○ Breaks in production can prove very expensive
What is cell production?
○ Workplace is divided into cells, each cell is concerned with the production of ‘product families’, which are groups of products which require a sequence of similar operations
○ Inside a cells machines are grouped together in order to complete one good from start to finish
Benefits of cell production?
○ Product flexibility is increased
○ Lead times are able to be reduced
○ Team working is encouraged
Negatives of cell production?
○ A firm may not be able to use machinery as efficiently compared to flow production
○ Output will be lower than mass production
○ More investment and planning is required in a new management and control process
What is productivity?
Measurement between inputs into the production process and the resultant outputs, such as:
→ Output per worker
→ Output per hour/day/week/month/year
→ Output per machine
How do you calculate unit cost?
Divide total costs by the number of units produced. This measures the average cost per unit produced, as measured over a particular time period
What are economies of scale?
Cost advantages that a business can exploit by expanding their scale of production. Most businesses find that, as production output increases, they can achieve lower costs per unit.
