1. Introduction

Question 1

UCL?

Answer 1

upper control limit

Question 2

LCL

Answer 2

lower control limit

Question 3

VOP?

Answer 3

voice of the process

Question 4

VOC?

Answer 4

voice of the customer

Question 5

Problems regarding VOP and VPC?

Answer 5

It is ont the same.
If they are to far away, customers will not be happy
- narrow down USL & LSL does not change the UCL and LCL and will lead to waste and rework

Question 6

most common situation?

Answer 6

Ppecial cause of variation

• not stable
• not predictable
• will still need to test everythinh

Question 7

Goal?

Answer 7

• Stabilize
• make predictable
• find relationship between control factors and
• stable process—> test testing
• find the most important factors

Problem
(- the trick is to go upstream)

Question 8

USL?

Answer 8

upper specification limit

Question 9

LSL?

Answer 9

lower specification limit

Question 10

longer ?

Answer 10

• less steep slope
• better quality
• slower

Question 11

DMAIC?

Answer 11

1. Defining
2. Measurement
   —> what is the baseline today?
   —> current situation
   —> can we trust the data?
3. Analyze
4. Implement
5. Control

Question 12

Implementing Lean and Six Sigma?

Answer 12

1. Lean
2. Six sigma

Problem:
- Bad lean metrics often caused by to much variation
while six sigma focus variation.

Question 13

Organizational process states?

Answer 13

manufacturing
- often from stabilization to optimization
info flow
- often from chaos to stabilization

Question 14

where can we often find the problem?

Answer 14

not in the system but maybe in the input, from the suppliers

Question 15

where can we often find the problem?

Answer 15

not in the system but maybe in the input, from the suppliers

Question 16

Continual improvement

Answer 16

1. What do you want to accomplish (big Y)
   —> customers requirement on the output
2. By what method
   —> limitation
   —> what does your jurisdiction allows you to implement
   —> use AIM
3. How will you know? (small y)
   —> where we define our problem
   —> effecting scoping tool

Question 17

PROBLEM WITH EFFECTIVE SCOPING

Answer 17

1. Engineers are trained to save problems
2. Engeneers do it with the tools they have
3. Think everyone sees the situation the same way as them
4. selecting specialist for problem solving before the problem is defined

Question 18

principal route for improvements is?

Answer 18

1. Find how y depends on:
   —> inputs x
   —> control parameters C
   —> noise N
2. Use control parameters order to
   —> mitigate variation in y from x,c,n
   —> improve Y

Question 19

The steps in effective scoping?

Answer 19

1. FOCUS THE OUTPUT
   - identify what the process does
2. What comes out from this activity
3. In what context will it be used
4. What is required of it?
5. FOCUS ON WHAT TO IMPROVE
   - Identify the objective with the project before manning
6. what measure should be improved? -y
7. Can that precise y be measured and what is the baseline?
8. What Y cannot be lost in the process?
   - constraints
9. FOCUS THE MANNING
   - Where can changes be made
10. where can the changes be made?
11. What inputs are supplied and from whom?
12. What does the system require input?
