Operations management
operations management: the process that uses the resources of an organisation
to provide the right goods or services for the customer.
In the context of the above definition, ‘right’ means ‘what the customer wants’.
It may mean quality and price to one customer, but convenience and flexibility to
another.
Unit 2: Managing a business
Operations management
Identifying operations issues
Customers have many requirements, so operations management looks at a variety of
issues. In the AQA AS Business Studies course it looks at:• location (Unit 1)• resources to use and converting them into outputs (Unit 1)• capacity utilisation• organising stock control • quality• customer service • working with suppliers• using technology
Unit 2: Managing a business
Operations management
Operational targets
operational targets: the goals or aims of the operations function of the business.
A business that achieves its operational targets would be described as ‘operating
efficently’. This efficiency may mean low costs or high quality etc.
Three examples of operational targets are:• unit costs• measures of quality• capacity utilisation
Unit 2: Managing a business
Operations management
Unit costs
unit cost: the cost of producing 1 unit of output.
unit cost = total cost
units of output
The unit cost is also known as the average cost (AC) or average total cost (ATC).
The target for a business is to achieve low unit costs.
Example:
A business produces 10 units of output at a total cost of £70.
average (or unit) cost = £70/10 = £7
Unit 2: Managing a business
Operations management
Unit costs: calculations
Based on the data above, calculate the unit costs of products A to D.
Assuming these products are of the same quality, which product is manufactured most efficiently?
Total costs (£) Units of output Unit costs (£)
Product A 470 20
Product B 558 30
Product C 1,060 50
Product D 1,945 100

Measures of quality
Quality is defined as ’those features of a product or service that allow it to satisfy
(or delight) customers’.
Because ‘quality’ depends on people’s opinions, there will be different views on what
is meant by quality.
What measures of quality would you use for a business?
Hint: they must be measurable!
Some examples of measures of quality and a brief comment on the logic behind their
use are provided on the following two slides. How do yours compare?
Unit 2: Managing a business
Operations management
Examples of measures of quality (1)
Note that this is just a sample of quality measures — a good quality measure will be
geared towards the specific needs of the individual firm.
Customer satisfaction ratings • A survey of customers can reveal customer opinions on a numerical scale (e.g.
1–10) or using qualitative measures (e.g. excellent — very good — good — etc.) • As the purpose of a product/service is to satisfy the needs of the customer, this is
an excellent way of measuring whether quality has been achieved.
Customer complaints
• This calculates the number of customers who complain (it is sometimes
measured as a percentage of the total number of customers).• Although this might seem to be a negative approach, it is a good way of
measuring whether a company has problems that it needs to solve.
Unit 2: Managing a business
Operations management
Examples of measures of quality (2)
Scrap rate or wastage rate• This calculates the number of items rejected during the production process as a
percentage of the number of units produced.• This will show the business whether its production methods are working
effectively, guiding it towards areas that might need improvement.
Punctuality• This calculates the degree to which a business delivers its products (or provides
its services) on time. It is often measured as a percentage:
punctuality = deliveries on time × 100
total deliveries • This measure is used by many businesses, especially those involved in
transporting goods (e.g. haulage firms) or customers (e.g. rail franchises).
Unit 2: Managing a business

Using quality measures: question
Based on the data below, decide which company is providing the best quality and
which one is providing the lowest level of quality for its customers.

Unit 2: Managing a business
Operations management
Using quality measures: answer (2)
Best performerFirms A, B and D all average second place, so a case could be made for each one.
Factors to consider:• the quality measure(s) deemed most important by customers• the quality measure(s) deemed most important by the firm• the numerical difference in ratings (e.g. B has a much higher rating for customer
satisfaction than A, but is only slightly behind A on delivery times)
(It could be argued that the first column is the crucial one because it measures the
overall view of customers.)
Unit 2: Managing a business
Operations management
Capacity utilisation: key terms
capacity: the maximum total level of output or production that a business can
produce in a given time period. A company producing at this level is said to be
producing at full capacity.
capacity utilisation: the percentage of a firm’s total possible production level that
is being reached. If a company is large enough to produce 100 units a week, but is
actually producing 92 units, its capacity utilisation is 92%.
under-utilisation of capacity: when a firm’s output is below the maximum
possible. This is also known as excess capacity or spare capacity. It represents a
waste of resources and means that the organisation is spending unnecessarily on its
fixed assets.
capacity shortage: when a firm’s capacity is not large enough to deal with the
level of demand for its products. This means that certain customers will be
disappointed and sales will be lost.
Unit 2: Managing a business
Operations management
Calculating capacity utilisation
capacity utilisation: the extent to which the company’s maximum possible output
is being reached.
capacity utilisation (%) = actual output per annum (month) × 100
maximum possible output per annum (month)
Example: a company can produce 5,000 units but is actually producing 3,800 units.
Capacity utilisation is:
3,800 × 100 = 76%
5,000
Unit 2: Managing a business
Operations management
Spare capacity
In the previous example, the company could increase production by 1,200 units or
24% of 5,000 units. This is known as its spare capacity.
There is no one ideal target percentage, but many people believe that 90% capacity
utilisation is a sensible target.
At 100% there is no scope for maintenance and repair, to respond to sudden orders,
or to deal with emergency situations that may occur.
Thus firms like to have some spare capacity.
BUT…spare capacity means ‘unused’ resources and higher fixed costs per unit.
Unit 2: Managing a business
Operations management
Managing capacity utilisation
In terms of capacity utilisation, there are two types of situation that a firm needs to
manage:• under-utilisation of capacity (also known as excess capacity or spare
capacity)• capacity shortage
Spare capacity is the more normal situation. What causes it?
Unit 2: Managing a business
Operations management
Causes of spare capacity (under-utilisation of capacity)
• new competitors or new products entering the market• fall in demand for the product• unsuccessful marketing• seasonal demand• over-investment in fixed assets
Unit 2: Managing a business
Operations management
Disadvantages of spare capacity
• Firms have a higher proportion of fixed costs per unit. • These higher costs will lead to either lower profit levels or the need to increase
price to maintain the same profit levels, and therefore to lower sales volume.• Spare capacity can portray a negative image of a firm, suggesting that it is
unsuccessful. • With less work to do, employees may become bored and demoralised, lowering
their motivation and efficiency.
Unit 2: Managing a business
Operations management
Advantages of under-utilisation
Spare capacity means that there is more time for maintenance and repair of
machinery, for training and for improving existing systems.
There may be less pressure and stress for employees, who may become overworked
at full capacity.
Under-utilisation allows a company to cope with a sudden increase in demand.
Unit 2: Managing a business
Operations management
Achieving full or high capacity utilisation
Methods include:• increasing marketing to boost demand• lowering price• rationalisation — improving efficiency by cutting the scale of operations. This
reduces the capacity of a firm and so increases capacity utilisation.
Unit 2: Managing a business
Operations management
Ways of reducing capacity
Methods include:• selling off all or a part of its production area• changing to a shorter working week or shorter day• laying off workers• transferring resources away from an area of the business (e.g. moving workers
away from a branch with low capacity utilisation)
Unit 2: Managing a business
Operations management
Managing capacity shortage
If there is a shortage of capacity, the firm will try to increase its capacity.
Ways of increasing capacity include:• building or extending factories/plants• asking staff to work overtime or longer hours• recruiting more temporary or part-time staff• hiring new full-time staff• subcontracting
Unit 2: Managing a business
Operations management
Subcontracting
subcontracting: when an organisation asks another business to make all or a part
of its product.
Many businesses use subcontracting as a way of reducing capacity utilisation
problems.
By asking other firms to supply goods, the original firm can increase supply to match
demand without needing to increase its own factory size.
It can then reduce the amount of work that it subcontracts if it needs to cut output.
Unit 2: Managing a business
Operations management
Advantages of subcontracting
• Businesses can react to changes in demand more quickly if they have access to
a number of different firms’ production plants.• Subcontractors may be more specialised and therefore more efficient in a
particular activity. • Subcontracting lets a firm focus on its core business and helps it to avoid
becoming involved in activities in which it is less competent.• A one-off (non-standard) order can be given to a subcontractor so that the
business benefits from the order but suffers no disruption to its normal
production.
Unit 2: Managing a business
Operations management
Disadvantages of subcontracting
• Quality is no longer directly under the firm’s own control. • Excessive subcontracting erodes a company’s operations base and its ability to
initiate research. • The subcontractor wants to make a profit, so it is possible that it will be more
expensive to subcontract.• Subcontracting may require a firm to give confidential information to a supplier,
such as details of its methods and patents.
Unit 2: Managing a business
Operations management
Stock control and capacity utilisation
stock control: the management of levels of raw materials, work-in-progress and
finished goods to reduce storage costs, while still meeting the demands of the
customer.
Stock control can overcome capacity utilisation problems: • Holding high stock levels enables a business to release additional products on to
the market when demand increases. • During periods of low demand, the level of stocks can be replenished by
producing more than is being demanded.
Unit 2: Managing a business
Operations management
Dealing with non-standard orders
non-standard orders: a business decision relating to a one-off contract.
Often the non-standard order requires a response to a request to supply a fixed
quantity of a product at a particular price (invariably a lower price than usual).
A decision on a non-standard order will be taken primarily on the basis of its financial
consequences, but the firm will also need to look at the impact on the functional
aspects of the firm, such as operations.
Unit 2: Managing a business
Operations management
Non-standard orders:operational factors
• the level of spare capacity available• the scope for subcontracting• the impact on costs• is there potential for future (profitable) orders? • the effect on staff morale

Chapter 24
Developing effective operations: quality
Unit 2: Managing a business
Operations management
Quality
quality: those features of a product or service that allow it to satisfy (or delight)
customers.
Quality is subjective — a matter of personal opinion — and views of it will vary from
individual to individual.
Think of a product and list five ways of measuring the quality of that product.
Unit 2: Managing a business
Operations management
Some measures of quality
Possible measures of quality are listed below (like quality itself, these measures are
subjective):• appearance• reliability and durability• functions (added extras)• after-sales service• brand/image/reputation• environmental friendliness
How do these compare with your list? Why are there differences between your list
and this list?
Unit 2: Managing a business
Operations management
Benefits of quality to a business
• increase in sales volume• creating a unique selling point (USP) and enhancing the firm’s reputation• greater scope for increasing the selling price• pricing flexibility, as customers will want to buy the product even if price is
changed• possible reduced manufacturing cost and reduced wastage if high-quality
materials and processes improve the efficiency of the production process
Unit 2: Managing a business
Operations management
Issues involved in introducing and managing a quality system
• Costs. Quality procedures require a great deal of administrative expense to set
up and monitor. • Training. This can be a major issue in the introduction of a new quality system,
as a system of quality assurance relies on a well-trained workforce that is able to
understand and implement the quality system that the business uses. • Disruption to production. In the short run, the training programme provided
can be quite disruptive to existing production methods.
Unit 2: Managing a business
Operations management
Distinction between quality control and quality assurance
Quality control• This is a system that uses inspection as a way of finding any faults in the good or
service being provided.• Inspectors are employed to check the accuracy of completed work.
Quality assurance• This is a system that aims to achieve or improve quality by organising every
process to get the product ‘right first time’ and prevent mistakes ever
happening.• Quality assurance concentrates on the process of production. The idea of self-
checking is crucial to quality assurance.
Unit 2: Managing a business
Operations management
Quality control: benefits
• Inspection at the end of the process can prevent a defective product reaching
the customer, thus eliminating a problem with a whole batch of products.• It is a more secure system than one that trusts every individual to do his or her
job properly, particularly if workers want to avoid responsibility.• Inspectors may be highly skilled in detecting problems and may spot quality
problems that are being repeated by different workers.
Unit 2: Managing a business
Operations management
Quality control: problems
• By placing responsibility for quality failures on the inspector, quality control does
little to encourage individuals to improve the quality of their output.• Employing an inspection team is an expense that could be viewed as
unnecessary if the products are produced ‘right first time’.• Giving workers responsibility for their own work helps to increase the interest,
variety and responsibility of their job, and thus helps to motivate them.
Unit 2: Managing a business
Operations management
Quality assurance: benefits
• Ownership of the product or service rests with the workers rather than with an
independent inspector, giving them greater responsibility.• Theorists such as Herzberg argue that the responsibility will motivate workers.• Costs are reduced because there is less waste — any faults are discovered
during the process.• Because an individual will not want to be blamed for a faulty product, each
worker checks what he or she receives, reducing the possibility of a faulty
product.
Unit 2: Managing a business
Operations management
Systems of quality assurance: TQM
The most widely recognised quality assurance system is total quality management,
often known as TQM.
TQM is a culture of quality that involves all employees of a firm.
Key features of TQM are:• The quality chain. Each person involved in production treats the receiver of their
work as if they were an external customer.• ‘Right first time’. Employees aim for defect prevention rather than detection.• All staff share a commitment to continuous improvement.• Partnerships are built with suppliers.• Staff are educated and trained to take responsibility for their own quality.• Employees are encouraged to take pride in their work.
Unit 2: Managing a business
Operations management
Kaizen
The Japanese philosophy of kaizen has given rise to quality systems based on
continuous improvement.
Kaizen (or ‘continuous improvement’) is a policy of implementing small, incremental
changes in order to achieve better quality and/or greater efficiency. These changes
are invariably suggested by employees and emanate from a corporate culture that
encourages employees to identify potential improvements.
Unit 2: Managing a business
Operations management
Quality standards
ISO 9001: the international standard of quality assurance that is equivalent to
BS 5750.
BS 5750: a British Standards award granted to organisations which possess quality
assurance systems that meet the standards set.
These standards aim to increase quality throughout an organisation. Firms must
show that they have quality systems that cover the quality of their working methods,
services and processes as well as the quality of their products.
Unit 2: Managing a business
Operations management
Benefits of quality standards
• Marketing advantages from having ‘proof’ of high quality standards.• Assurance to customers that products meet certain standards. Some
organisations insist on these awards before agreeing to trade with a firm, as this
helps to guarantee the quality of their supplies.• Greater employee motivation from the sense of recognition.• Financial benefits from the elimination of waste and the improved reputation of
the firm.

Developing effectiveoperations: customer service
Unit 2: Managing a business
Operations management
Customer service
customer service: the overall activity of identifying and satisfying customer needs
and the delivery of a level of service that meets or exceeds customer expectations.
customer expectations: what people think should happen and how they think they
should be treated when asking for or receiving customer service. Higher
expectations among customers mean that better customer service must be provided.
customer satisfaction: the feeling that the buyer gets when he or she is happy
with the level of customer service that has been provided and the degree to which
customer expectations have been met.
Unit 2: Managing a business
Operations management
What do customers want?
Customers do not always want the same service from a business.
Consequently, most businesses use their own measurements of customer
satisfaction, to make it relevant to their own customers.
A survey by the Institute of Customer Service (ICS) found that customers had ten top
priorities that affected customer satisfaction.
Remember: you are all customers!
Make a list of five factors that you believe would fit into the top ten.
See whose list is closest to the results of the ICS survey on the next slide.
Unit 2: Managing a business
Operations management
Calculating your score
Score 10 marks if you had the number one factor, 9 marks for the second most important
factor… down to 1 mark for the tenth factor.
Customer priorities/expectations were:
Quality of the product or service 10 marks
Friendliness of staff 9 marks
Efficiency in dealing with problems/complaints 8 marks
Speed of service or delivery 7 marks
Helpfulness of staff in general 6 marks
Effectiveness in handling enquiries 5 marks
Extent to which customers felt ‘valued/important’ 4 marks
The competence of staff in completing their tasks 3 marks
The ease with which the transaction was completed 2 marks
The extent to which the customer was kept informed 1 mark
Unit 2: Managing a business
Operations management
Other findings of the ICS survey
Service businesses (e.g. hairdressers and decorators) and professional services
(e.g. architects) are best at satisfying customers.
The public sector and utilities (e.g. electricity suppliers) bring up the rear.
The survey also highlighted the importance of employee satisfaction. Typically, the
more satisfied employees are, the more highly motivated they are to provide a good
service. This leads to a higher level of customer satisfaction.
Unit 2: Managing a business
Operations management
Methods of meeting customer expectations
Customer expectations can be met through a series of stages:
Stage 1: Conduct market research to find out customer expectations so that
customer service targets the right factors.
Stage 2: Introduce relevant training in customer service into the organisation so
that the workforce can meet and surpass customer expectations.
Stage 3: Set up quality procedures and set quality standards so that the
organisation is geared towards the needs of its customers.
Stage 4: Monitor performance against these standards so that high quality and good
customer service are maintained.
Unit 2: Managing a business
Operations management
Meeting customer expectations through market research
• The standard for ‘quality’ is set by the customer, who is therefore the best place
to start. • Primary market research can be used to get comments from consumers. • Secondary market research can help a firm to discover successful measures used
by other businesses.• The Department for Business, Enterprise and Regulatory Reform (BERR) can
provide data on the factors and features that are most valued in the
marketplace. • Other sources of secondary market research are surveys such as the UK
Customer Satisfaction Index and the annual CompariSat survey provided by FDS
International.
Unit 2: Managing a business
Operations management
Meeting customer expectations through training
• A look at the top ten factors shows how many depend on the quality of the
employees. Training helps employees to be good at their jobs.• Companies often provide specific training in customer care. • Vocational qualifications in customer care help employees to improve customer
service.
Unit 2: Managing a business
Operations management
Meeting customer expectations through quality control, quality
assurance and monitoring quality standards
• Quality control can ensure that faulty goods are identified and rejected as a
result of the inspection process.• Quality assurance helps to improve customer satisfaction by ensuring that goods
and services are ‘right first time’.• Any business that subscribes to a quality standard, such as ISO 9001, must
regularly monitor its activities to ensure that it is still meeting the standards that
have been set. This will normally be sufficient to ensure that high-quality
customer service is offered.
Unit 2: Managing a business
Operations management
Main benefits of high levels of customer service
• Impact on sales volume. High-quality service that exceeds the expectations of
customers will lead to increased demand for the goods and services provided by
a business.• Creating a unique selling point (USP). The quality of customer service can
be used as a USP to enhance a company’s uniqueness and individuality. • Impact on selling price. The USP will enable a business to charge higher prices
and thus earn higher profits. • The firm’s reputation. Companies with a reputation for good customer service
are likely to gain repeat business and have a solid base of loyal customers.
Unit 2: Managing a business
Operations management
Additional benefits of high levels of customer service
• A motivated workforce. Good relations with customers may make the
workplace a happier working environment. • Lower costs. Costs may be reduced because a high level of customer service is
likely to mean fewer complaints to handle. • References. In some cases, organisations will insist on proof of high levels of
customer service (e.g. testimony from other customers) before agreeing to trade
with a firm. • Public relations. Positive publicity arising from good customer service can be
used for PR.

Working with suppliers
Unit 2: Managing a business
Operations management
Working with suppliers
supplier: an organisation that provides a business with the materials that it needs
to carry out its business activities.
For a manufacturer, suppliers mainly provide the raw materials and components
needed to produce the finished good.
For a retailer, suppliers invariably provide the finished goods that the retailer sells.
Unit 2: Managing a business
Operations management
Choosing effective suppliers
A business may improve its efficiency to a large extent by choosing effective
suppliers.
When choosing suppliers, the main factors that a business will consider are:• prices• payment terms• quality• capacity• reliability• flexibility
Unit 2: Managing a business
Operations management
Choosing suppliers: prices
A business will seek value for money from its suppliers.
If the supplier offers low prices, a business can benefit in two ways:• The business can reduce the final selling price of its own product and therefore
gain a competitive advantage.• The business can keep its final selling price the same, but enjoy the benefit of a
higher profit margin/higher added value.
BUT…a business must be cautious when choosing a supplier that is offering low
prices.
Unit 2: Managing a business
Operations management
Potential problems from low-price suppliers
The prices charged by the supplier may be low because:• the quality of the raw materials is low• the supplier may be unreliable in terms of meeting delivery dates • the supplier may be inflexible if a sudden change is needed• the supplier is in financial trouble and desperate to get a contract
Overall, the business must consider how important price is to its own customers. If
they are willing to pay high prices, low-price supplies are less important.
Unit 2: Managing a business
Operations management
Choosing suppliers: payment terms
payment terms: arrangements made concerning the timing of payment and any
other conditions agreed between buyer and seller.
It is normal practice in the business world for credit to be offered to the buyer of
supplies of materials. This means that payment is delayed, often by 28 or 30 days.
There are two major reasons for this type of agreement:• Buyers will want this type of agreement because there will be a delay between
the purchase of the materials and the receipt of sales revenue from selling of the
final product. This delay may cause cash-flow problems for the buyer. • Suppliers will offer payment terms in order to get business. Offering payment
terms to buyers should boost the supplier’s sales, as they will be chosen in
preference to those not offering credit.
Unit 2: Managing a business
Operations management
Importance of payment terms
This will depend on the situations of both buyer and supplier.
If the supplier is manufacturing a component that takes a long time to produce, it is
likely to need cash immediately and so it will not want to offer payment terms.
If it is an organisation such as a wholesaler that has been given credit by the
manufacturers, it will not be under pressure to get cash quickly. Therefore it can
offer credit terms to its buyers.
ConclusionCredit is most likely to be offered when buyers of supplies face cash-flow difficulties
because the end product takes a long time to sell. Payment terms are less likely to
be needed if the final product brings in sales revenue quickly.
Unit 2: Managing a business
Operations management
Choosing suppliers: quality
In many industries, price competitiveness is being superseded by quality
considerations. Therefore, quality is a critical factor to consider when choosing and
working with a supplier.
Key benefits of high-quality supplies are that they enable a business to produce high-
quality products. These will:• increase the volume of its sales• increase its selling price and probably its profit margin• create a unique selling point (USP)• enhance its reputation and its customer and brand loyalty• reduce its manufacturing costs through elimination of waste
Unit 2: Managing a business
Operations management
Importance of quality
For buyers, a poor-quality component or product can cause major damage to a
manufacturer’s reputation.
Overall, the significance of quality will depend on the product in question:• For an economy brand that is sold on the basis of its low price, quality will be
relatively unimportant.• For a product being sold on the basis of its quality, the product itself and its
components must meet high standards.
Unit 2: Managing a business
Operations management
Choosing suppliers: capacity
capacity: the maximum possible output of an organisation.
An organisation will need to be reassured that a supplier can meet the quantity of
supply that it requires.
If the supplier is providing a unique component or material that cannot be obtained
from other sources, failure to supply might seriously damage the reputation of the
buyer.
If the supplier is providing a component or material that can be sourced from other
suppliers, its capacity may be less critical.
Unit 2: Managing a business
Operations management
Choosing suppliers: reliability
reliability: the extent to which the supplier meets the requirements of the buyer.
Typically, reliability can be measured by the percentage of deliveries on time or the
degree to which a supplier meets the terms of the contract to supply.
For a manufacturer, an unreliable supplier can lead to the whole production line
coming to a halt because a crucial material or component is not available.
For a retailer, a failure to supply can affect its reputation. Customers will blame the
retailer if they are unable to buy a product that they want.
Unit 2: Managing a business
Operations management
Choosing suppliers: flexibility
There may be situations where an organisation radically needs to change its orders
from suppliers — for example:• sudden changes in demand for a product• the liquidation of a rival supplier, leaving buyers short of a product or component
In these circumstances, an organisation will want its suppliers to be flexible enough
to adapt to the changing circumstances.
Flexibility is a reason why many large organisations do not buy all of their materials
from one single source, even where one supplier could provide all of their needs.
Unit 2: Managing a business
Operations management
Role of suppliers in improving operational performance
Suppliers can help a business to achieve each of its three main operational targets:• Lower unit costs. An efficient supplier can offer low-priced materials, helping a
customer/business to keep its own costs low.• Higher quality. If the supplier is able to meet quality standards consistently,
the buyer of the materials will find it easier to produce high-quality products.• High capacity utilisation. A flexible supplier can allow a business to increase
its capacity utilisation suddenly by supplying more supplies.
Other possible benefits include:• Suppliers may develop new products or materials.• Suppliers may find ways of extending the life of a product.
Unit 2: Managing a business
Operations management
Porter’s value chain and suppliers
According to Michael Porter in his book Competitive Advantage, a business can gain
a competitive advantage in one of two ways:• cost advantage• differentiation
Working with suppliers, a business can achieve both of these benefits.
The cost advantage comes from finding the supplier offering the lowest prices.
Differentiation is achieved if a supplier is able to provide a unique product or
material.

Using technology in operations
technology: the applications of practical, mechanical, electrical and related
sciences to industry and commerce.
Technology influences industry and commerce in many ways. Examples are:• robotics• automation (e.g. stock control)• communications• design
In groups, identify five aspects of business that have been affected by technology in
recent years.
Produce a report, based on your five aspects, highlighting:• the benefits of the technology to businesses• any problems for businesses using new technology• any benefits and problems for other people or organisations
Unit 2: Managing a business

Robotics
Uses of robotics:• handling operations• welding• other production applications (e.g. dispensing liquid, painting and coating
materials)• assembling• packaging and palletising• measurement, inspection and testing• hazardous applications
Unit 2: Managing a business
Operations management
Automation: key terms
automation: the use of machinery to replace people in the production process,
usually to carry out routine activities.
computer-aided manufacturing (or manufacture) (CAM): the use of computers
to undertake activities such as planning, operating and controlling production.
Unit 2: Managing a business
Operations management
Areas of operations management benefiting from technology
Planning and controlling• Computers can be used to plan the most efficient way of producing a product. • Production can be monitored by the computer and remedial action taken if
problems arise.
Operating• CAM (computer-aided manufacture) has increased productivity and reduced the
problems arising from human error. • Flexible programming allows a fully automated line to produce different varieties.
Unit 2: Managing a business
Operations management
Technology and stock control
Stock control is aided by technology in the following ways:• Computer programs linked to statistics on patterns of consumer purchases allow
firms to anticipate changes in stock levels more accurately. This reduces the
possibility that a firm will run out of stock or build up unnecessarily high levels. • Computerised systems allow organisations to recognise their current stock levels
immediately, reducing the need for time-consuming manual checks. • EPOS (electronic point of sale) systems monitor stock levels and can also order
new stock from suppliers automatically when the stock has been reduced to a
certain level (the ‘reorder level’).• Organisations with many branches can also use technology to establish the
locations where stock is being held.

Technology and communications
information and communication technology (ICT): the acquisition, processing,
storage and dissemination of vocal, pictorial, textual and numerical information by a
microelectronics-based combination of computing and telecommunications.
Benefits of ICT are:• It allows a firm to improve both internal and external communications, improving
efficiency and the firm’s understanding of its market.• Internal information can be processed and amended more quickly. • Company intranets enable employees and, where necessary, suppliers and
customers to access company information continually. • Technology increases the speed of communication and the scope for greater
responsibility. It allows firms to delayer and operate wider spans of control.• Loyalty cards allows firms to accumulate information on the buying habits of
their customers.

The internet and operations
The internet brings many possible advantages to firms that use it:• It can eliminate the need for expensive high street premises. • It can reduce the need for staff.• It adds flexibility to business operations, which no longer need to fit in with
traditional business structures. • Data can be stored more cheaply and accessed more quickly.

Technology and design: key terms
computer-aided design (CAD): the use of computers to improve the design of
products.
CADCAM: an approach that combines computer-aided design and computer-aided
manufacture, using IT to aid both the design and the manufacture of an item.

Benefits arising from CAD or CADCAM
• Different ideas can be introduced and compared faster in a CAD system than in a
manual one. • Two-dimensional drawings can be transformed into three-dimensional images
and rotated in order to demonstrate the whole range of possible views. • Programs can simulate testing (e.g. wind tunnel simulations). This can save
considerable sums of money by eliminating the production and testing of
expensive prototypes.• New products have been created by technology (e.g. mobile phones).

Operations management
Technology: reducing costs
• The use of technology to replace manual systems in areas such as planning,
office work, manufacturing and stock holding has greatly reduced labour costs.• ICT can be used in production planning in order to devise the most cost-effective
way of manufacturing a product.• Use of the internet enables businesses to locate away from expensive sites.

Operations management
Technology: improving quality
• Computer-based quality assurance systems can overcome the possibility of
human error and also provide more rigorous scrutiny of quality. • ICT enables businesses to understand customers’ requirements more fully and to
adapt their products.• The flexibility of IT (e.g. 24-hour access to automated teller machines) can
improve the quality of the product and/or customer service.

Operations management
Technology: reducing waste
• Stock control systems ensure that orders are placed at the most appropriate
time so that excessive stock levels do not build up. • Integrated systems of stock control can also identify branches holding stock that
may be needed by other branches. • Many business activities can be carried out quicker with the benefit of
technology, saving valuable time and money.

Operations management
Technology: increasing productivity
• Machines can work at a faster speed than humans. • Computerised systems allow organisations to keep closer control over their stock
levels, reducing the need for time-consuming manual checks and therefore
reducing wage bills.• ICT may be used to plan the most efficient approach to production. This enables
the business to improve productivity.

Other benefits of technology
• Flexibility. The adaptability of technology is now enabling businesses to provide
an immediate response to consumers’ demands or sudden changes. • Financial monitoring. ICT greatly improves the budgeting process and the
monitoring of variances.• New products. New and better products and services can be created through
technology.• Better working conditions — through factors such as reductions in the level of
noise and greater control over working temperatures.

Issues in introducing and updating technology (1)
The use of new technology can also cause problems: • People are often concerned by change. ICT can lead to job losses for workers in
traditional skilled crafts. This causes stress for workers, so productivity may fall.• ICT can undermine group morale by breaking up teams. • For many firms, the most significant problem is the cost of new technology. Not
only is it expensive to introduce, but also it needs regular updating.

Operations management
Issues in introducing and updating technology (2)
• The nature of technology is changing constantly. Consequently, there is a
constant need to replace hardware and software, and to provide continuous
training for staff, again adding to costs. • Consumers can use the internet to compare prices. ICT has the potential to force
prices and profits down.
SummaryAn organisation needs to weigh up the pros and cons before deciding whether it
should introduce or update its technology.
Usually the short-term problems and costs must be weighed up against the
long-term benefits.
