unit 4: operations management Flashcards
Production (key points)
- Provision of a product or service to satisfy customers wants or needs. Process involves firms adding value to a product.
- Value added is the difference between the cost of inputs (raw materials or components) and the final selling price
Productivity (key points)
The output measured against the inputs used to create it.
Productivity can be measured by: Output (over a given time period) / number of employees
Businesses want to become more efficient with production, this means that the amount of output produced per worker employee will rise and costs of production will fall.
Lean production (key points)
increasing speed, reducing waste, reducing distance
Flow production (key points)
- Ongoing production of products in large quantities.
- Product moves continuously through production process
- Time taken on each task must be evenly distributed
Batch production (key points)
Large quantities of a product that may vary slightly.
- Similar items are produced together
- Each batch goes though one stage of production before moving onto the next stage
- Concentrate skills
- Achieve better use of equipment and so produce good quality products more economically than manufacturing them individually
flow production (pros/cons)
+ Cost per unit of production reduced through improved work and material flow
+ Suitable for manufacturers of large quantities
+ Capital intensive meaning it can work constantly
+ Less need for training and skills
- Very long setup time and reliant on high machinery
- High raw materials and finished sticks unless lean production used
- Goods are mass produced – less differentiation for the customer
- Production is shut down if flow is stopped
Batch production (pros/cons)
+ Cost saving can be achieved by buying in bulk
+ Stull allows customers some choice
+ Products can be worked on by specialist staff or equipment at each stage
+ Allows a firm to handle unexpected orders
- Takes time to switch production of one batch to another
- Requires the business to maintain higher stocks of raw materials and work-in-progress
- Takes may becoming boring or repetitive – reducing motivation
- Size of batch dependent on capacity allocated
Job production (key points)
Produces items from scratch – involving one individual, often bespoke to the customer.
- One off or small number of items produced
- Undertaken by small, specialist businesses
- Made to customer specifications
Job production (pros and cons)
+ Customer requirements and changes can be handled
+ Associated with higher quality products
+ Employees can be better motivated – more job satisfaction
+ A flexible production method
- Individual cost of one unit may be high
- Often labour-intensive = high labour costs
- Requires close consultation with the client
- Usually reliant on high skills
Just in time production (JIT):
Constantly getting supplies, therefore not paying for storage.
Limited buffer stocks
Regular re-orders
Low max inventory level
Requires organisation + planning
Just in case production (JIC):
Have a buffer stock
Storage costs are higher
Delivery is less regular
Less likely to disappoint customers
Definition of start-up costs
incurred before the business can start to operate, such as a deposit on rented property.
Definition of operating costs
sometimes called expenses, refers to money spent on a regular basis, once a business is up and running. For example electricity.
Definition of fixed costs
Fixed costs: a charge that is not relative to the output of a business e.g rent/mortgage, tax and rates, staff salaries, insurance, advertising.
Definition of variable costs
direct costs associated with the production of a product or service e.g raw materials, energy costs, wages.
