Chapter 3.4 Flashcards
1
Q
Name the two key ways to review and enhance specifications
A

- Using techniques such as value analysis and value engineering to ensure that users receive the highest levels of value and cost
2
Q
Name the three levels that standardisation in product manufacture can occur
A
- Individual parts and components
- End products they are used in
- Processes used to make them
3
Q
Name 4 benefits of standardisation
A
- Cost reduction
- Quality
- Flexibility

4
Q
Name the 5 ways the manufacturing process changes with increased volume and variety of parts used in production
A
- Job shop
- Production cells
- Flexible manufacturing systems
- Mixed lines
- Dedicated lines
5
Q
Explain a job shop
A
When a wide range of end-products each call for a different range of materials and the possible number of the end products means they are made to order as it is uneconomic to store all of them in inventory
6
Q
Explain production cells
A
The manufacturing process is divided into small groups that make sub-assemblies that are similar in terms of the parts or equipment used
7
Q
Flexible manufacturing system
A
Method for procuring goods that is readily adaptable to changes in the product being manufactured or the quantity being produced
8
Q
Explain mixed lines
A
Production lines in which small quantities of different products are made with quick changeover in set-up between production runs
9
Q
What three things are often referred to as batch production
A
Production cells
Flexible manufacturing system
Mixed lines
10
Q
Explain dedicated lines
A
Only a small number of products are made as the set-up costs for the production line are high
11
Q
What is often referred to as mass production
A
Dedicated lines
12
Q
Name an advantage of mixed lines
A
It increases efficiency and reduces the amount of inventory needed to meet demand
13
Q
Name a main advantage of dedicated lines
A
It gives a low unit cost
14
Q
Name an advantage of standardising products, materials and components
A
Allows a larger quantity of a product to be made at a time. This has the effect of reducing the unit cost
15
Q
What concept may you use when utilising standardisation in a service company
A
Lean
16
Q
Are the concepts of lean also applicable to manufacturing organisations?

20
Q
Define lead time
A
The time it takes to deliver the product or service once the order is placed
21
Q
What formula shows the relationship between lead time and the drivers of lead time (Little’s law)
A
Lead time = amount of work in process / average completion rate
22
Q
What does process efficiency measure?
A
The percentage of time that work spends in value-adding activities and is a key measure of any process
23
Q
What is the formula for process efficiency
A
Process efficiency = value-add time / total lead time
24
Q
What is likely if the process efficiency is less than 10%
A
There is a lot of waste in the process
25
How to define waste
Anything that adds no value in the eyes of the customer
26
What is the amount of waste for an activity proportional to?
The delay that it causes
27
What are you likely to find if a process has not been through a lean assessment?

39
What effect does standardisation have on the learning curve?
Advantages

3. Give the final decision maker the opportunity to question and challenge the detail for each
71
How does value engineering differ from value analysis
Value analysis is concerned with existing products or services. Value engineering uses the same techniques but is applied to new products or services
72
What is a useful tool for value engineering
