4.1 – Production of Goods and Services
HomeNotesBusiness Studies – 04504.1 – Production of Goods and Services
Production is the effective management of resources in producing goods and
services.
The operations department in a firm overlooks the production process. They must:
Use the resources in a cost-effective and efficient manner
Manage inventory effectively
Produce the required output to meet customer demands
Meet the quality standards expected by customers
Productivity
Productivity is a measure of the efficiency of inputs used in the production
process over a period of time. It is the output measured against the inputs used
to produce it. The formula is:
Businesses often measure the labour productivity to see how efficient their
employees are in producing output. The formula for it is:

Businesses look to increase productivity, as the output will increase per employee
and so the average costs of production will fall. This way, they will be able to sell
more while also being able to lower prices.
Ways to increase productivity:
improving labour skills by training them so they work more productively and
waste lesser resources
introducing automation (using machinery and IT equipment to control
production) so that production is faster and error-free
improve employee motivation so that they will be willing to produce more
and efficiently so.
improved quality control and assurance systems to ensure that there are
no wastage of resources
Inventory Management
Firms can hold inventory (stock) of raw materials, goods that are not completed yet
(a.k.a work-in-progress) and finished unsold goods. Finished good stocks are kept
so that any unexpected rise in demand is fulfilled.
When inventory gets to a certain point (reorder level), they will be reordered
by the firm to bring the level of inventory back up to the maximum level again.
The business has to reorder inventory before they go too low since the
reorder supply will take time to arrive at the firm
The time it takes for the reorder supply to arrive is known as lead time.
If too high inventory is held, the costs of holding and maintaining it will be very
high.
The buffer inventory level is the level of inventory the business should hold
at the very minimum to satisfy customer demand at all times. During the lead
time the inventory will have hit the buffer level and as reorder arrives, it will
shoot back up to the maximum level.
Lean Production
Lean production refers to the various techniques a firm can adopt to reduce wastage
and increase efficiency/productivity.
The seven types of wastage that can occur in a firm:
Overproduction– producing goods before they have been ordered by
customers. This results in too much output and so high inventory costs
Waiting– when goods are not being moved or processed in any way, then
waste is occurring
Transportation-moving goods around unnecessarily is simply wasting time.
They also risk damage during movement
Unnecessary inventory-too much inventory takes up valuable space and
incurs cost
Motion-unnecessary moving about of employees and operation of machinery
is a waste of time and cost respectively.
Over-processing-using complex machinery and equipment to perform simple
tasks may be unnecessary and is a waste of time, effort and money
Defects– any fault in equipment can halt production and waste valuable time.
Goods can also turn out to be faulty and need to be fixed- taking up more
money and time
By avoiding such wastage, a firm can benefit in many ways
less storage of raw materials, components and finished goods- less money
and time tied up in inventory
quicker production of goods and services
no need to repair faulty goods- leads to good customer satisfaction
ultimately, costs will lower, which helps reduce prices, making the business
more competitive and earn higher profits as well
Now, how to implement lean production? The different methods are:
Kaizen: it’s a Japanese term meaning ‘continuous improvement’. It aims to
increase efficiency and reduce wastage by getting workers to get together
in small groups and discuss problems and suggest solutions. Since
they’re the ones directly involved in production they will know best to identify
issues. When kaizen is implemented, the factory floor, for example, is
rearranged by re-positioning machinery and equipment so that
production can flow smoothly through the factory in the least possible time.
Benefits:
increased productivity
reduced amount of space needed for production
improved factory layout may allow some jobs to be combined,
so freeing up employees to do other jobs in the factory
Just-in-Time inventory control: this techniques eliminates the need to hold
any kind of inventory by ensuring that supplies arrive just in time they are
needed for production. The making of any parts is done just in time to be used
in the next stage of production and finished goods are made just in time they
are needed for delivery to the customer/shop. The firm will need very reliable
suppliers and an efficient system for reordering supplies.
Benefits:Reduces cost of holding inventory
Warehouse space is not needed any more, so more space is available
for other uses
Finished goods are immediately sold off, so cash flows in quickly
Cell Production: the production line is divided into separate, self-contained
units each making a part of the finished good. This works because it improves
worker morale when they are put into teams and concentrate on one part
alone.
Methods of Production
Job Production: products are made specifically to order, customized for each
customer. Eg: wedding cakes, made-to-measure suits, films etc.
Advantages:Most suitable for one-off products and personal services
The product meets the exact requirement of the customer
Workers will have more varied jobs as each order is different,
improving morale
very flexible method of production
Disadvantages:Skilled labour will often be required which is expensive
Costs are higher for job production firms because they are usually
labour-intensive
Production often takes a long time
Since they are made to order, any errors may be expensive to fix
Materials may have to be specially purchased for different orders,
which is expensive
Batch Production: similar products are made in batches or blocks. A small
quantity of one product is made, then a small quantity of another. Eg: cookies,
building houses of the same design etc.
Advantages:Flexible way of working- production can be easily switched
between products
Gives some variety to workers
More variety means more consumer choice
Even if one product’s machinery breaks down, other products can still
be made
Disadvantages:Can be expensive since finished and semi-finished goods will
need moving about
Machines have to be reset between production batches which delays
production
Lots of raw materials will be needed for different product batches,
which can be expensive.
Flow Production: large quantities of products are produced in a continuous
process on the production line. Eg: a soft drinks factory.
Advantages:There is a high output of standardized (identical) products
Costs are low in the long run and so prices can be kept low
Can benefit from economies of scale in purchasing
Automated production lines can run 24×7
Goods are produced quickly and cheaply
Capital-intensive production, so reduced labour costs and increases
efficiency
Disadvantages:A very boring system for the workers, leads to low job
satisfaction and motivation
Lots of raw materials and finished goods need to be held in inventorythis is expensive
Capital cost of setting up the flow line is very high
If one machinery breaks down, entire production will be affected
Factors that affect which production method to use:
The nature of the product: Whether it is a personal, customized-to-order
product, in which case job production will be used. If it is a standard product,
then flow production will be used
The size of the market: For a large market, flow production will be required.
Small local and niche markets may make use of batch and flow production.
Goods that are highly demanded but not in very large quantities, batch
production is most suitable.
The nature of demand: If there is a fair and steady demand for the product, it
would be more suitable to run a production line for the product. For less
frequent demand, batch and job will be appropriate.
The size of the business: Small firms with little capital access will not
produce using large automated production lines, but will use batch and job
production.
Technology and Production
Automation: equipment used in the factory is controlled by computers to
carry out mechanical processes, such as spray painting a car body.
Mechanization: production is done by machines but is operated by people
CAD (computer aided designing): a computer software that draws items being
designed more quickly and allows them to be rotated, zoomed in and viewed
from all angles.
CAM (computer aided manufacturing): computers monitor the production
process and controls machines and robots-similar to automation
CIM (computer integrated manufacturing): the integration of CAD and CAM.
The computers that design the product using CAD is connected to the CAM
software to directly produce the physical design.
EPOS (electronic point-of-sale): used at checkouts/tills where operator scans
the bar-code of each item bought by the customer individually. The item
details and price appear on screen and are printed in the receipt. They can
also automatically update and reorder stock as items are bought.
EFTPOS (electronic funds transfer at point-of-sale): the electronic cash
register at the till will be connected to the retailer’s main computer and
different banks. When the customer swipes the debit card at the till,
information is read by the scanner and an amount is withdrawn from the
customer’s bank account (after the PIN is entered).
Advantages of technology in production
Greater productivity
Greater job satisfaction among workers as boring, routine jobs are done by
machines
Better quality products
Quicker communication and less paperwork
More accurate demand levels are forecast since computer monitor inventory
levels
New products can be introduced as new production methods are introduced
Disadvantages of technology in production
Unemployment rises as machines and computers replace human labour
Expensive to set up
New technology quickly becomes outdated and frequent updating of systems
will be needed- this is expensive and time-consuming.
Employees may take time to adjust to new technology or even resist it as their
work practices change.
