SSGB Chapter 7

Question 1

All the following are tools for six sigma Improve phase EXCEPT?

Answer 1

Implementation plan

Implementation Plan is an output from six sigma Improve phase

Question 2

Which of the following is an output from the six sigma Improve phase?

Answer 2

Cost/ benefit for different solutions

Cost/Benefit for different solutions is an output from six sigma Improve phase

Question 3

Ratio of profit divided by investment is also referred to as:

Answer 3

Return on investment

ROI(Return on investment) is a measure of the income (or profit) divided by investment. ROI measures how effectively the company uses its capital to generate profits

Question 4

From a six sigma project perspective, while calculating ROI, investment refers to:

Answer 4

ratio of project benefits to project costs.

For a six sigma project perspective, the project cost is the investment, and income is the quantified benefits accrued from the project. So, ROI for a six sigma project is the ratio of project benefits to project costs.

Question 5

In project selection, objective of a company should be to:

Answer 5

Maximize ROI

In project selection, objective of any company is to maximize ROI

Question 6

Increased revenue, reduction in costs, cost avoidance, improved productivity and improved customer satisfaction are examples of

Answer 6

Project benefits

Project benefits can be divided into categories like increased revenue, reduction in costs, cost avoidance, improved productivity, improved customer satisfaction etc.

Question 7

Which tool helps to compare how the proposed solutions compare with the existing system in meeting the specified criteria

Answer 7

Solution design matrix

Solution design matrix helps to compare how the proposed solutions compare with the existing system in meeting the specified criteria

Question 8

In solution design matrix, the key criteria on which the project will be evaluated can be got from any one of the following EXCEPT:

Answer 8

Implementation plan

In the solution design matrix, we determine the key criteria on which the project will be evaluated (the criteria are obtained from the project charter, process map, QFD, Kano Model, Ishikawa diagrams etc.)

Question 9

When using solution design matrix, what is the benefit rating given to each criteria in the existing solution?

Answer 9

0

While using solution design matrix, benefit rating for each criteria is determined by taking inputs from team members. Existing design is provided a rating of “0” on all the criteria

Question 10

Any variable that may influence a process is also called:

Answer 10

Factor

Factor: Any variable that may influence a process

Question 11

Specific parameter used to decide if the process is improving is called

Answer 11

Response variable

Response Variable: Specific parameter used to decide if the process is improving; helps in determining the type of data to be collected

Question 12

Setting or category that a variable may take is also called:

Answer 12

Level

Levels: Setting or category that a variable may take. Two or more levels could be chosen for each category

Question 13

Simplest experiments used in DOE are:

Answer 13

One factor at a time

One-factor-at-a-time: Level of the first factor is changed while others stay the same. One or more trials are run until the best level of first factor is determined which maximizes the response variable. These are the simplest experiments used in DOE.

Question 14

In your DOE experiment, only some of the possible factors and levels are studied simultaneously. This is an example of:

Answer 14

Fractional factorial experiment

Fractional factorial experiment: Only some of the possible factors and levels are studied simultaneously
