2.4.1 - Productivity Flashcards
What is productivity
- Productivity is the output per input (person or machine) per hour
• Productivity is how a business can measure how hard a person or a machine is working
• This helps in planning, scheduling, monitoring, budgeting and running the business
• We talk about productivity in terms of “efficiency” if it is good or “inefficiency” if it is bad
What is production
Production- is the total amount of output that is produced in a time period
what are the 4 methods of productions
- Job
- Batch
- Flow
- Cell
What is job production
• Job production is where one single product is made at a time
• Products are made for a specific client or customer
• Products made are high quality, which means higher prices can be charged
• However, the production process can be slow and labour intensive
- goods are made by skilled craftspeople who will be well motivated
what are the advantages of job production
• Bespoke, unique, one off, to customers measurements or specifications e.g. a kitchen
• Very motivated workers who can see one item made from start to finish
• Motivated workers are normally more productive and have lower rates of absenteeism
What are the disadvantages of job production
- • Skilled labour and craftsmen are expensive
• Wide range of tools may be required
• Hard to speed up if demand increases
What is batch production
• This is the production method used when a business wants to make more than one item at a time
• Goods are made in batches, and can be switched over to make something different on the same production line
What are the advantages of batch production
• Production can be changed to meet customer needs or fluctuations in demand
• Standard production of items means it can be mechanised less labour involved than job production
• Employees specialise so become good at their job
• Lower skilled workforce means lower wages can be paid
What are the disadvantages of Batch Production
• Small batches carry higher average unit costs (EOS)
• Workers may be less motivated with repetitive work
• Idle time between batches needs to be managed as this is wastage
• need to clean machinery
What is Flow Production
• Flow production uses production lines with continuous movements of items through the process
• Many mass produced products are made this way such as; cola, cars and toothpaste
• The factory would be laid out in assembly lines
• Correct production process to choose when standardised products need to be mass produced in huge volumes in a continuous process
What are the advantages of flow production
• A business can make larger quantities which means they can bulk buy raw materials and save money (economies of scale)
• Automated and computerised production means improved quality and more complex designs can be made in shorter times
• As production is continuous stocks of parts and raw materials don’t need to be held this means a business can use the JIT (just-in-time) system
What are the disadvantages of flow production
• High costs to buy the factory and machinery
• Low motivation of staff due to repetitive tasks
• Break downs and lost production can be costly
• Very inflexible, hard to change the factory machinery to make different products, the production process will be set up to make just one item e.g. bottled cola
What is cell production
• Cell production is dividing up production into separate self contained areas that are each responsible for a section of work
• In the DR Martens video you can see that cutting the leather is one section, then sewing is another etc.
• Each cell will have a team leader and a team of multi-skilled workers
What are the advantages of cell production
• Wastage through movement of materials is reduced
• Time waiting for stock to arrive is reduced
• Bottlenecks in the production process are reduced (where everything builds up waiting to go to the next stage)
• Cell production can mean increased worker commitment and motivation and therefore increased productivity
What are the disadvantages of cell production
• Any breakdown of machinery will stop the production
• Needs more staff to supervise than a continuous flow
• Expanding can be hard as space may be limited or restricted by tasks
