Front 1

Name 2 characteristics of effective supply chains.

Back 1

Communication and Collaboration.

Front 2

Name the 2 types of supply chains.

Back 2

Fishers Model: Functional/Innovative Products and Responsive/Efficient supply chains.

Front 3

One type of supply chain ___________ work for all of your products.

Back 3

will probably not

Front 4

____________________________ is an effective tool in understanding your products supply chain and where to strategically focus continuous improvement efforts.

Back 4

Enterprise Value Stream Mapping

Front 5

Effective supply chain management does not stop __________________. Information must be flowed to the lowest level of the supply chain.

Back 5

at the first tier supplier

Front 6

What is simulation?

Back 6

Obtaining the reality of without the essence of...

Develop representation (or model) of real world system

Then experiment with model to observe, evaluate and study system over time

Front 7

Why Simulate?

Back 7

* To evaluate system before implementation
* To understand system behavior
* To communicate with others
* For instruction and training
* For prediction (eg, predicting impact of various changes

Front 8

What is Model Verification?

Back 8

* Checking that simulation code is performing properly

Front 9

What is Model Validation?

Back 9

* Determining if model is accurate representation of real world system

Front 10

Statistical Analysis: What does it mean?

Back 10

* What confidence do we have in the simulation results?

* Additional accuracy can be achieved by increasing run length of each replication or number of replications.

* How large of sample is needed?

* NOTE:Doubling accuracy requires quadrupling sample size or number of replications.

Front 11

What is Lean?

Back 11

It shortens customer lead time(response time) by eliminating waste.

Front 12

Where did Lean come from? (History of Lean)

Back 12

2 Books:

The Toyota Production System by Taiichi Ohno

"The Machine that Changed the World" by Jim Womack(the term Lean Production was coined in this book)

"Lean Thinking" by Dan Jones

Front 13

What is Waste?

Back 13

Any activity that is non-value added.

Front 14

What is a Value Added activity?

Back 14

Any activity that increases the market FORM or FUNCTION of the product or service(things a customer is willing to pay for).

Front 15

What is a Non-Value Added activity?

Back 15

Waste, as in employees not working up to par, Machine breakdowns, Order Processing, etc.

Front 16

What are the 8 Deadly Wastes?

Back 16

Defects
Overproduction
Waiting
Not utilizing people's KSAs
Transportation
Inventory
Motion
Excess processing

Front 17

Describe Defects:

Back 17

It's the Inspection and repair of material in inventory, caused by such things as weak processing control, unbalanced inventory level, and customer needs not understood(among other things)

Front 18

Describe Overproduction:

Back 18

-Making MORE then is required by the next process.

-Making EARLIER then is required by the next process.

-Making FASTER then is required by the next process.

Caused by Just-in-case logic, Misuse of automation, Long Process Set-up, Unlevel scheduling, and Unbalanced workload.

Front 19

Describe Waiting:

Back 19

Idle time created when waiting for parts, materials, machines, information, help, etc.

Caused by Unbalanced workload, Unplanned maintenance, and Unlevel scheduling(among others)

Front 20

Describe Not utilizing people's KSAs:

Back 20

The waste of not using people's abilities(mental, creative, physical, skill).

Caused by Old guard thinking, politics, the business culture; Poor hiring practices, Low or no investment in training, Low pay, high turnover strategy.

Front 21

Describe Transportation:

Back 21

Transporting parts and materials around the plant.

Transportation Waste is caused by Poor plant layout, Large batch sizes, and long lead times(among others).

Front 22

Describe Inventory:

Back 22

"Any supply in excess of a 1-piece flow through your manufacturing process".

Causes of Excess Inventory include Unleveled Scheduling, Poor Market Forecast, Reward System, and it Protects the company from inefficiencies and unexpected problems(like the way an deep river protects from all the rocks at the bottom).

Front 23

Describe Motion:

Back 23

It's the movement of people or machines that does not add value to the product or service.

Causes of Motion Waste include Poor people/machine effectiveness, Inconsistent work methods, and Extra "busy" movements while waiting(among other things).

Front 24

Describe Excess Processing:

Back 24

It's the effort that adds no value to the product or service from the customers' viewpoint.

Causes of Excess Processing include Product Changes without process changes, the True customer requirements are undefined, and there are Redundant approvals(among other things).
