2. Scales of Production Watch the video…
Context:
New topic on Scales of Production.
What:
Scales of Production is about how many of an item are made at one time.
Why:
All engineered products will be produced at a certain scale.
Previously:
You will have looked at some scales of production in KS3 D&T.
Next:
You are going to make some products at different scales.
Watch the video…
List the items that you see, how many of each of these items do you think are made in one go? 
Fill out the charts…
Item
Number Made

3. To understand the scale of engineering production: one-off.
Learning Objectives
To understand the scale of engineering production: one-off.
These issues affect all aspects of the course and should be considered throughout.

4. Learning Outcomes Progress – Identify what one-off production is.
Good Progress
–Identify some advantages and disadvantages of one-off production.
Exceptional Progress
–Describe one-off production to enable future comparisons.

6. One-Off Production
One-off or individual production, is used to manufacture one-off products.
It is often related to as “tailor made”, bespoke or customised solutions.
A key feature is often a high-cost product that is manufactured to a client specification.
This kind of one-off product may be higher cost due to more expensive materials and time consuming hand crafted production and finishing.
Wedding dresses and custom made pieces use this type of manufacture.
This is the most expensive type of manufacture.
Highly skilled workers will be used, and will work on one job at a time. This means that it is extremely expensive.

7. One-Off Production Advantages Disadvantages High unit cost
Low production efficiency
Requires skilled labour
High labour costs
General tools and equipment
Low initial investment

8. Production Scales: Key Words
Characteristic
Description
Unit cost
How much each item will cost.
Tools and equipment
What is used to make the item.
Initial investment
How much it costs to set up to make the item.
Production efficiency
How quickly and cheaply overall the product is to make.
Labour type
How much training do the people making the item need.
Labour costs
How much do the people making the item have to be paid.

Description
Examples
Unit cost
How much each item will cost.
High cost item - expensive
Medium cost item
Low cost item - cheap
Tools and equipment
What is used to make the item.
General tools - can be used to make other items
Specialised tools - can only be used to make a few items
Dedicated tools - can only be used to make one item
Initial investment
How much it costs to set up to make the item.
High investment - expensive
Medium investment
Low investment - cheap
Production efficiency
How quickly and cheaply overall the product is to make.
Low efficiency - is slow and expensive
Medium efficiency
High efficiency - is quick and cheap
Labour type
How much training do the people making the item need.
Skilled - workers who have had lots of training
Semi-skilled - workers who have had some training
Unskilled - workers who have had no training
Labour costs
How much do the people making the item have to be paid.
High wages - expensive
Medium wages
Low wages - cheap
