Q

Why is capacity utilisation important?

A
  • Measure production efficiency and helps set objectives

Q

Risks associated with low capacity utilisation

A
  • less economies of scale = high unit costs = high selling price = not competitive
  • capital tied up in assets eg. labour, equipment and recourses
  • less likely to break-even and be profitable in long term

25
Why might a business be operating at low capacity utilisation?
reduced market share, varying demand (expected or unexpected), bad HR department (bad training of workforce), repairing of machinery,low labour productivty
26
problems with operating at a high capacity utilisation
de-motivates workforce due to high stress due to higher workload quality affected due to worsened quality control = reduce sales and negative brand image less flexible to meet sudden demand
27
What is labour productivity?
The output per employee during a given time period
28
Formula for labour productivity
Output per period/no.employees = x units per employee
29
Influences on labour productivity
Skill of employees, suppliers lead time, machinery quality/quantity, recourses available, training, number of employees,motivation
30
What is a capital intensive industry?
An industry that requires assets of machinery/tech in high volumes to meet demand eg factory
31
What is a labour intensive industry?
A business requiring a large workforce to meet demand eg. restaurants
32
How can a business improve labour productivity?
Improve training of workforce, improve layout of facilities, hire skilled workers, consistent leadership.

Unit cost formula
Total production costs (£) / Total output (units)
35
What is internal economies of scale?
Increasing output from within the business which lowers costs
36
What is external economies of scale?
Within an industry to benefit an entire industry
37

38
What is purchasing economies of scale?
Bulk buying to reduce unit costs
39
What is technical economies of scale?
Specialist equipment purchased to improve efficiency
40
What is marketing economies of scale?
spreading the fixed marketing cost across the purchased good inflows = less per unit
41
What is network economies of scale?
Increased number of users for the product or service reudce operating (indirect) costs
42
What is financial economies of scale?
Access to cheaper finance as they pose less risk eg more loans and more overdrafts
43
What is managerial economies of scale?
employing more specialised employees due to a larger firm = increase efficiency

48
How can a business improve its quality?
Training employees, working to improve motivation, tech better, quality control, quality assurance, work closely with suppliers
49
What is the difference between quality assurance and quality control?
Assurance = checking at every stage Control = check at end of process
50
Advantages associated with quality control
Be monitored well to stop faulty being received by customers, more time efficienct than assurance
51
Disdvantages associated with quality control
Requires specialist inspector, only identified at the end so wasted material = wasted capital.
52
Advantages associated with quality assurance
Spot faults early = less waste, provide focus of low defect rate via objectives for quality, enhance customer reputation if less faulty.
53
disadvantages associated with quality assurance
staff training required, can reduce labour productivity, slowed production.
54
Define inventory
The raw materials, work In progressed and finished goods that are held by a firm to enable production and meet demand.
55
What are the 3 types of inventory?
- Raw materials - Work-in-progress - Finished goods
56
Name 3 costs of holding inventory
- Storage cost - Employees costs - Obselence cost ( Can't be sold anymore eg out of fashion or date) - Stock out risk (run out) - Interest involved in tying up capital
57
What is the just-in-time production method?
Where inventory is required just when it's needed *no buffer stock* = lower storage costs, low lead times and a reliable relationship is required with the supplier.
58
Advantages of low inventory for a business
Less risk of obselence Lower cost for storage Less capital is tied up = more cash flow
59
Advantages of high inventory for a business
less risk of delays meet sudden demand due to unexpected circumstances less chance of stock out economies of scale
60
What is the objective of having an inventory control chart?
To keep total costs of holding inventory low
61
formula for calculating the re-order level of a business ( inventory control chart )
(lead time x average daily usage) + buffer stock = re-order level
62
What is buffer stock on an inventory control chart?
Level below minimum stock held that is there for contingency purposes.
63
define supplier
A supplier is a business or individual that provides good and services to another
64
What is a supply chain?
The network between company and its suppliers to produce and distribute a product
65
What are some characteristics of a good supplier
good quality services/products cost that suits lead time that suits location that suits lead Time length ( very short if JIT model) communicate reliable amount able to provide suits
66
what are the two types of suppliers?
Strategic and commodity
67
what is the difference between a commodity and strategic supplier?
Commodity: Can be bought elsewhere Strategic: Can't succeed without that specific supplier
68
What is a trade credit?
Where a business buys goods or service from another and pays later.
69
What are some factors that affect a businesses choice of suppliers?
- Quality - Payment terms - Ability to meet demand (capacity) - Reliability - Price - Ethics of operation
70
What is mass customisation?
Large scale production while enabling customer to make preferences
71
What is CAD?
Computer aided design
72
Why is CAD (computer aided design) useful for a firm?
- CAD can help with innovation = unique models - ^ competitively - Can test before launch or mass production - Able to alter designs to pick which is best
73
Advantages of a firm using robots
High speed and reliability, less workers needed, accurate processes, less risk for staff if in hazardous environment
74
Disadvantages of a firm using robots
Maintenance costs, hard to produce, less jobs = less team working
75
76
What is CAM?

79
Drawbacks of having technology within a firm
Less job opportunities, loss of human touch=demotivating, cost of new technology development, if break = hard to meet demand and disrupted processes
80
what is lean production?
Organising production and operations to minimise waste (via cutting out processes that don't add value)

How can a firm reduce waste via lean production?
- reduce waiting time (idle equip) - Stock levels managed - Reduce defects - Less transport of materials - reduce over production
82
What is just in time production?
Manufacturing system where materials/components are delivered immediately before required in production - stock levels low - inputs only when needed - Type of lean production

87
How can a businesses performance be altered by suppliers?
- Low quality inventory = bad reputation + lower sales - Able to meet demand will affect sales and turnover - The payment terms will affect cash flow and therefore ability to pay liabilities - Unreliable delivery = less competitive as less reliable lead times
88
What's a lead time?
How long it takes for a supplier to deliver goods.
89
What is outsourcing aka. subcontracting?
When an organisation uses an outsider supplier
90
Why outsource?
- Increases capacity to meet demands - Employment of less specialist staff = lower labour costs - Accept more contracts = diversify customer base - reduce infrastructure costs ie. storages, office space
91

Law services not done in-house Software maintenance Financial advisors Capital intensive jobs like factory work cleaning
92
Drawbacks of outsourcing
May be expensive Less reliable quality as supplier may have worse quality than the business Unethical supplier practices affect the ethics of company Less control over quality
