Demand for product
Changing customer needs
New technology
Job production and flow production
Job production is production of one of items by skilled workers
Flow production is mass production on a continuous production line with division of labour
Batch production and cell production
Bad production is a small batches of identical items
Cell production is divided into a set of tasks each second completed by Work group
Try to achieve efficiency dependability and speed of response objectives
Lean production
Streamlined production with waste at a minimum
Could help meet environmental and deficiency objectives whilst ensuring high-quality
Capacity
Maximum output with the resources currently available
Capacity utilisation
How much capacity a business is using currently?
Capacity utilisation formula as a percentage
Output divided by capacity multiplied by 100
Why is it bad to have 100% capacity utilisation?
There wouldn’t be no downtime such as the machines are on all time if a machine breaks down it will cause the lays as Work piles up waiting to be fixed
There is no margin for and the business can’t temporarily increase output for seasonal demand and one of orders will have potential customers
Firms with high capacity utilisation can increase the capacity how?
Use the facilities for more of the working week they can start working in 2 to 3 shift in a day and then weekend
Buy more machines
Increase staff levels
Increasing productivity
Subcontracting/outsourcing
Businesses use another phone to do some work on its behalf such as a manufacturer of detergent might make detergent for a supermarket and package it with the supermarkets only label
Outsourcing is in busy periods to make unexpected increases in demand
What is bad about under utilisation?
In efficient and increases unit cost because it causes fixed costs to spread over fewer units of output
How to deal with under utilisation
Increase demand such as promotion
Spare capacity by subcontracting Work
Reduce their own capacity by closing part of the production facilities this is called rationalisation or downsizing
Labour productivity formula
Output per period divided by number of employees
Labour productivity
Measure of how much each employee produces
Increased this by improving motivation training or using new technology this should increase efficiency
Just in time production
Keep stock levels very low
Aims to reduce waste of materials by having a little stock as possible
Storage cost storage juice and cash flows improved. There is less waste more flexible to cope with demand and changes.
No stock when there is production strikes
Timebased management
Aims to reduce waste of time in production process
Depends on flexible production facilities
Effective communication between managers and production staff as essential
Reduces lead times and gives a competitive advantage
And can help
However, it may be placing speed above quality
