Foundation of 6 sigma

Question 1

“DMAIC” abbreviation means

Answer 1

Design, Measure, Analyze, Improve, Control

Question 2

What is the DMAIC process?

Answer 2

used to improve the current capabilities of an existing process

Question 3

the define phase is about

Answer 3

what is the problem? goal? and target? to achieve

Question 4

the measure phase

Answer 4

what is the current performance? how far are we from the target? identify the GAP

Question 5

the analyze phase

Answer 5

what is the gap in the current performance? What are the root causes of the the gap? why is the gap there?

Question 6

In the improve phase we ask how can we _____ the process. How can we ______ that our ____ will improve the process

Answer 6

how can we change the process? how do we verify that our changes will improve the process

Question 7

the control phase

Answer 7

are our improvements to the process consistent over time? how do we maintain improvement in the future

Question 8

the define phase uses what methodology

Answer 8

VOC, CTQ, Stakholder, SIPOC ( suppliers, inputs, processes, outputs, customers) Financial analysis , Project Charter, graphical data e.g Pareto Chart, Histogram, line graph

Question 9

the measure phase uses what types of methodology

Answer 9

process review, measure system analysis, data collection, process capability(z-score, process stability using control

Question 10

the analyze phase uses what types of methodology

Answer 10

determine causes, 5whys, fishbone diagram, root cause analysis, hypothesis testing

Question 11

the improve phases uses what types of methodology

Answer 11

generation of solution ideas, (benchmarking,)

risk analysis on solution, create implementation plan for verifying solution

Question 12

the control phase uses what types of methodology

Answer 12

used for monitoring, reacting plan, validate final financial results (not immediate), hand over toprocess owner

Question 13

X means input or output

Answer 13

Input

Question 14

Y means input or output

Answer 14

output

Question 15

controlling ______ controls output

Answer 15

input

Question 16

DMAIC Approach Formula

Answer 16

y=f(x)

Question 17

Define Lean

Answer 17

lean is the removal of waste. its a systematic approach to identify and eliminate waste or non value activities from a process

Question 18

JUST IN TIME JIT

Answer 18

right product, right amount, right time

Question 19

difference between lean and six sigma

Answer 19

lean is geared towards reducing waste in a process that will reduce cost and increasing speed.
6 Sigma is more about reducing the variations in a process by making sustainable changes

Question 20

3 processes of lean:

Answer 20

1. change mindset/culture 2. non value added process- 3. more effort is required, variations in the process

Question 21

variation means

Answer 21

when no two items/servies are the same

Question 22

variation is often due to differences in the

Answer 22

manpower, machines, material, methods, measurement, Mother Nature

Question 23

A common cause is

a. not part of the process on a regular basis
b. random changes in the process that cannot be avoided

Answer 23

B. Random changes thats cant be avoided. (it is consistently day after day)
variation only removable by making change to existing process usually requires management intervention

Question 24

An assignable cause is

a. not part of the process on a regular basis
b. random changes in the process that cannot be avoided

Answer 24

a. not part of the process on a regular basis
Variations in the process that are not part of the process on a regular basis. EXAMPLE: a size change that occurs the chips build up around a holding device machine
