Production adds value to the resources it uses by turning them into products consumers want and are willing to pay for.
![Page 11: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/11.jpg)

For example, a business that produces 500,000 chocolate bars with a market value of $1 million but which cost only $700,000 to produce will have added $300,000 to the resources it has used in their production—labour, cocoa powder, milk, machinery, vehicles, foil, paper, electric power, etc.
![Page 13: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/13.jpg)
For example, a business that produces 500,000 chocolate bars with a market value of $1 million but which cost only $700,000 to produce, will have added $300,000 to the resources.
It has used in their production—labour, cocoa powder, milk, machinery, vehicles, foil, paper, electric power, etc.
What other resources does the company needed for their production?
![Page 14: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/14.jpg)
The total output of a business organisation is measured by the volume or value of all the goods or services it produces each week, month or year.
![Page 15: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/15.jpg)
Productivity The level of production is the
output of the business Productivity is how a business
can measure its efficiency
Productivity = Quantity of output Quantity of outputs
![Page 16: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/16.jpg)
The aim of any business will be to combine its resources in the most efficient way.
Productivity, measures how efficiently resources are being used in production.
![Page 17: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/17.jpg)
Productivity in a business will have increase if more output or revenue is produced from the same amount of resources, or the same output or revenue can be produced using fewer resources.
![Page 18: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/18.jpg)
A firm that fails to increase productivity at the pace or at a faster rate than rival firms will have higher production costs and therefore lower profits than its competitors.
![Page 19: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/19.jpg)
Labour productivity is the most common measure of productivity in a business
![Page 20: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/20.jpg)
Labour productivity is calculated by dividing total output over a given period of time,
Average Productivity of labour = _____total output_____ Number of employees
![Page 21: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/21.jpg)
The average productivity of labour is a useful measure of how efficient workers are and how efficiently they use other resources.
![Page 22: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/22.jpg)
For example, if a company employs 10 workers who produce 200 plant pots each day.
How much is the average product per employee?
the average product per employee per day is 20 pots
![Page 23: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/23.jpg)
If the daily output will rise to 220 pots per day without employing additional workers.
How much is the average product per employee? ______________________
then productivity will have increased to 22 pots per worker per day.
![Page 24: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/24.jpg)
Productivity in business organisations producing services can be more difficult to measure.
![Page 25: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/25.jpg)
For example, a hair salon could measure the number of customers or hair treatments per day per employee, but not all employees in the salon will be hairdressers. Some may be office staff or cleaners, so how can we measure their productivity?
![Page 26: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/26.jpg)
Productivity is also difficult to measure in organisations that do not produce a physical output or earn revenue
![Page 27: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/27.jpg)
Improving productive efficiency
Training employees to improve their skills and to use new technologies
Rewarding employees who increase their productivity with performance-related pay
![Page 28: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/28.jpg)
Improving the working environment to increase employees’ job satisfaction
Introducing automation
![Page 29: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/29.jpg)
In addition, productivity can be increase by: Replacing old equipment and
machinery with new technologies Automating production by replacing
labour with modern computer-operated machinery
![Page 30: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/30.jpg)
Ways to increase producti
vity
Improve employee motivation
Introduce new
technology
Improve inventory control
Train staff to be more efficient
Use machines instead of
people to do jobs
(automation)
Improved quality control/
assurance reduces waste

Benefits of increasing efficiency/productivity
Increase output relative to the inputs required
Lower costs per unit (average cost)
![Page 32: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/32.jpg)
Benefits of increasing efficiency/productivity
Fewer works may be needed, possibly leading to lower wage cost
Higher wages for workers increases motivation

Types of waste that can occur in production
Overproduction
Waiting
PRODUCING GOODS BEFORE THEY HAVE BEEN ORDERED
BY CUSTOMERS.
WHEN GOODS ARE NOT MOVING OR BEING PROCESSED IN ANY WAY
THEN WASTE IS OCCURING
![Page 36: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/36.jpg)
Types of waste that can occur in production
Transportation
Unnecessary inventory
MOVING GOODS AROUND UNNECCESARILY CAUSES WASTE AND
IS NOT ADDING VALUE TO THE PRODUCT
IF THERE IS TOO MUCH INVENTORY THEN THIS TAKES UP
SPACE
![Page 37: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/37.jpg)
Types of waste that can occur in production
Motion
Over processing
Defects
ANY ACTIONS, INCLUDING BENDING OR STRETCHING MOVEMENT OF THE
BODY OF THE EMPLOYEE WASTES TIME.
IF COMPLEX MACHINERY IS BEING USED TO PERFORM SIMPLE TASKS
THEN THIS IS WASTEFUL.
ANY FAULTS REQUIRE THE GOODS BEING FIXED AND TIME CAN BE
WASTED INSPECTING THE PRODUCTS
![Page 38: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/38.jpg)
Benefits of Lean ProductionQuicker production of goods and services
Less storage of raw materials or components
Better use of equipment No need to repair defects or provide a replacement service for dissatisfied customer
Less money tied up in inventories
Cutting out some processes which speeds up production

This involves suppliers delivering components or materials to production lines ‘just-in-time’ for them to be processed.
It also known as ‘stockless production’.
![Page 43: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/43.jpg)

The following requirements are necessary for just-in-time production to be effective:
the quality of materials and parts must be high.
the suppliers must be dependable and deliver on time.
the suppliers should be located near the company.
![Page 45: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/45.jpg)
Cell production has the flow production
line split into a number of self-
contained units.
Each team or ‘cell’ is responsible for a significant part of
the finished article
rather than each person only
carrying out only one very specific
task
team members are skilled at a number
of roles, so it provides a means for job rotation.

Choosing a method of production is very important in keeping the costs low.
Production methods can vary from the production of individual custom-made products to the continuous production of identical on a mass scale.
![Page 47: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/47.jpg)
There are 3 main methods of production
i) Job production ii) Flow
production iii)Batch Production
![Page 48: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/48.jpg)

Job Production
This method is used to provide goods & services that are made or delivered to order.
![Page 50: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/50.jpg)
Advantages Disadvantages
Products meet the precise requirements of their customers.
It is labour intensive.
Businesses can often include a premium in the price they charge their customers to reflect increased quality.
Wage costs can be high and it is time consuming.
Workers have varied jobs and many can make a finished product from start to finish. This can motivate the workers and create a sense of pride.
Any mistakes can be expensive as the products are produced to order.
![Page 51: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/51.jpg)
Involve mass production of identical or
standardized products in a
continuous moving process.
products are assembled, finished and
packed as they move or ‘’flow’
along a production line.
FLOW PRODUCTION
![Page 52: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/52.jpg)

Advantages DisadvantagesGoods can be produced quickly and cheaply.
The costs of equipment and machinery required can be high.
Lower costs of production can result in lower price.
Storage requirements and the costs of stocks of materials, components and finished product can be substantial.
Can reduce the number of workers needed and cut labour costs.Automated production can be continuous for 24 hours each day.
Machinery break downs, power cuts or supply problems with components will hold up production.
It allows workers to specialize in specific, repeated tasks.
Workers undertaking repetitive tasks may become bored.
![Page 54: Chapter 4 production and productivity (revised)](https://reader034.vdocuments.us/reader034/viewer/2022052705/58764f591a28ab0d198b65c5/html5/thumbnails/54.jpg)
involve producing a limited number of identical products
to meet a specific requirement or customer order

Advantages DisadvantagesA good way of adding variety to otherwise identical products to give consumers a wider choice.
It needs careful planning to minimize the amount of unproductive time between different batches.
Workers’ tasks are more varied than in flow production, reducing the risk of boredom.
Costs will be higher than for production on a mass scale.
