inputs
processes
outputs
What are the six categories of inputs?

labour (people putting ingredients into mixers)
Info from variety of sources (dog food recipe)

How can an organisation increase productivity and business competitiveness
competing on cost
competing on quality
competing on speed of delivery
What are the four strategies adopted to optimise operations?
facilities design and layout
Materials management
Management of quality
Extend of the use of technology
What is 1 disadvantage of the fixed position layout?
What are 2 advantages of the product layout?
PRODUCTIVITY - can generate a large volume of products (outputs) in a short period of time
COST - Cost is reduced because of the use of technology and machines, and staff only compete specialised tasks
What are 2 disadvantages of the product layout?
MOTIVATION - staff can become bored with repetitive, low skilled activities and may become lazy
SHUT DOWN - A problem on the production line can sometimes mean that the whole factory needs to be shut down
What are 2 disadvantages of the process layout?
CONFUSION - constantly changing schedules and routing make juggling process requirements more difficult, and can become confusing for staff
UTILISATION - équipement utilisation rates in process layout are frequently low, because machine usage is dependant upon a variety of output requirements
What are 2 advantages of the process layout?
PRODUCTIVITY IMPROVES - because whole factory doesn’t need to be shut down if there are defects or problems in one cell
MOTIVATION - improves because employees will be able to perform a variety of tasks, opposed to assembly line
What are 2 problems of a large amount of inventory being held by an organisation to ensure materials do not run out?
STORAGE - stock taking up storage for lengthy periods
USE-BY DATE - Materials can have a use-by date, which means they could become unusable after a period of time
What is an example of using inventory control to optimise operations? (other than TQM)
what are 2 advantages of ‘just in time’ to be used to control inventory?
- companies spend less money on raw materials because they buy just enough to make the products and no more
what is 1 disadvantage of ‘just in time’ to be used to control inventory?
if supplier of materials has a breakdown and cannot deliver goods on time it can shut down entire production process
Why does the supply chain need to be well managed?(2)
- if materials are of inferior quality, difficult to produce quality products
What are the 3 elements of quality management?
What are 2 advantages or quality control? plus one example of quality control
How can an organisation have quality assurance? (2)
How does total quality management (TQM) ensure quality?
quality becomes an organisation wide philosophy. Its aim is to crease a defect-free production process
how can employee empowerment be used to achieve TQM objectives?
what are 2 advantages of robotics?

how can operations manager manage staff appropriately? (adv and disadvantage to this)
how can operations manager act ethically and socially responsible with outputs? (adv and disadvantage to this)
