25
Volume flexibility
Being able to change the level of output of a product in accordance with customer demand
26
Operational objectives (5)
- costs - quality - speed of response - flexibility - environment
27
Unit costs equation
TOTAL COSTS / TOTAL OUTPUT
28
The more output you make, the BLANK the unit costs due to BLANK the fixed costs
lower, spreading
29
Labour productivity equation
TOTAL OUTPUT / NO. OF EMPLOYEES
30
Efficiency
Output (production) is maximised from a given level of inputs
31
Increasing labour productivity can be achieved by… (4)
- improving motivation - training - better management - introducing better/ new technologies
32
Difficulties in increasing labour productivity (3)
- increased output may reduce quality due to staff stress on large work load - resistant staff - staff demanding higher pay
33
Greater efficiency may allow a business to… (4)
- pay higher wages to workers - offer low prices / improve quality for consumers - spend more money on the local environment - increase overall profits for shareholders
34
Capacity utilisation
How much of our capacity we are utilising
35
Benefits of reaching high capacity (90-95%) (7)
- average unit costs will fall - benefits from economies of scale - profits increase - more competitive due to lower costs - opportunities for bonus payments for staff leading to increased labour productivity - shareholders dividends - stakeholder benefit
36
Problems with reaching full capacity (3)
- unable to accept new orders and produce them - little opportunity for maintenance of machinery - employees may feel under pressure and become demotivated so quality may decrease
37
What can a business do if capacity is not used highly ( e.g. 60%) (4)
- increase sales - improve marketing - produce different products with same resources - reduce capacity ( redundancies, shorter working week, downsizing)
38
Capacity shortage
When a firms capacity isn’t large enough to deal with the level of demand for its product
39
Ways of increasing capacity (4)
- building or extending factories or plants - ask staff to work overtime or longer hours - recruit more staff - outsource or subcontract
40
Capacity
Measure the maximum it can produce given its existing resources
41
Economies of scale
Cost advantages reaped by companies when production becomes efficient as costs are spread over a larger number of goods. As the scales of production increases, the unit costs decreases
42
Managerial economies of scale
Employ the best managers with specialist skills
43
Purchasing economies of scale
Buying in bulk
44
Technical economies of scales
Afford to buy better and advanced machinery
45
Marketing economies of scales
Large firms can afford expensive media that reach more customer and can complete more market research
46
Financial economies of scale
Large firms can borrow at lower rate as they are considered safer
47
How do economies of scale create barriers to entry
If a market has significant economies of scales that haven been exploited by the existing firms to a large extent, new entrants are deterred
48
Lean production
The aim to reduce waste throughout the organisation
49
Just in Time production
Ordering supplies only when we need them and holding as close to zero stock as possible
50
Benefits of JiT
- motivated workforce - multi skilling and flexibility - reduced waste - greater variety of goods
51
Difficulties of JiT
- fewer opportunities for bulk buying - halting of production if the supplier fails to deliver - difficulties meeting spikes in demand
52
JiT success depends on… (3)
- excellent communication - flexibility from suppliers and employees - infrastructure
53
Automation
The use of machinery to replace Human Resources
54
Capital intensive production
Businesses requiring a larger amount of capital (machinery) relative to labour
55
Advantages of capital intensive (3)
- machines can work continuously 24/7 - quality can be standardised - more cost effective if larger quantities are produced
56
Disadvantages of capital intensive
- Initial set up costs of machinery are high - breakdowns in production can be costly and cause delays - inflexible
57
Kaizen
Continuous improvement
58
Quality
Measured by the extent to which an operation meets its customer requirements
59
Quality assurance
Any systematic process of determining whether a product of service meets specified requirements (quality checked by staff for defects down production line )
60
+ and - of quality assurance
+ ensures product isn’t faulty + stops customer complaints + gives better customer satisfaction - time consuming - costs a lot to train staff
61
Quality control
How a company measures product quality and improves if it needs be (checked by inspectors at the end of the line)
62
+ and - of quality control
+ reduces chance of poor quality products reaching end users + inspectors (qualified) looks for faults so less employees need to be trained - faults only found at the end of line - high wastage costs - reworking faults costs time and money - waste resources, time and raw materials
63
Benefits of quality
- customer satisfaction - higher productivity - reputation improved - increased innovation
64
Difficulties of improving quality
- costly - difficult to agree
65
Producing to order
A strategy in which a business only manufactures a product once an order has been received from a customer
66
Advantages of producing to order
- ability to supple a product that meets a customers exact specification - reduces costs in holding inventory - potential for higher prices - production planning is easier - targeting markets
67
Disadvantages of producing to order
- fluctuations in production levels overtime - Higher costs due to inefficient capacity utilisation - inability to take advantage of sudden interest in a product - difficult to plan
68
Quality circles

69
Labour intensive production
When products are mainly produced by human workers
70
+ and - of labour intensive
+ customised and personally made products are easier to make + less expensive machinery costs + humans can use initiative to solve problems - quality of products can vary - skilled workers take time and money to train - unbalanced pay
71
Outsourcing
The transfer of activities, which were previously conducted in house, to a third party outside the business
72
+ and - of outsourcing
+ react to changes in demand more quickly + outsourcing providers may be more specialised and therefore more efficient + lets the firm concentrate on their core business - quality of product is no longer under the firms control - outsource provider may want profits so therefore may be more expensive
