Ans. TRIZ is the abbreviation for Theory of Inventive Problem Solving. It takes a gander at explicit issues to recognize specific examples that are intermittent across different ventures for a potential arrangement.

TRIZ is essential when usually utilized Six Sigma apparatuses are not permitting a task to move in the correct course.

5.) What do you mean by scatter plot diagram in Six Sigma?

Ans. A dispersed plot is a graphical chart addressing two unique factors. Normally, the autonomous variable lies on the even pivot, while the reliant variable lies along the upward hub. It is simpler and faster to track down a positive or negative connection between the different factors.

6.) How might you decipher a scatter plot diagram?

Ans. At the point when the information in the X-Y plane moves upwards from left to right, it is a positive connection. Alternately, assuming that the information moves downwards it is a negative relationship.

7.) What is P-value?

Ans. In Six Sigma, the P-value alludes to the likelihood esteem, which decides the meaning of results in light of the invalid speculation. The invalid speculation expresses the reason for the occasion was not laid out; subsequently, truly, the explanation that one attempts to demonstrate didn’t occur.

P-value falls somewhere in the range of 0 and 1 and if the p-value is:

• Under 0.5 – the occasion has a significant worth against the invalid speculation; thus it is critical according to measurements.
• More than 0.05 – the occasion has a significant incentive for the invalid speculation; consequently, elective theory gets dismissed

Notwithstanding, it isn’t recommended to totally depend on P-esteem. One must likewise take care of computing the impact size.

8.) What is effect size?

Ans. Effect size alludes to the proportion of the general greatness try to impact, which is quantitative. The bigger the size of the effect, the better falls the connection between the given factors. In less difficult terms, the computation of impact size brings about figuring out the connection between various factors.

• Updating new interaction projects – Also known as reengineering, this strategy centers around it are demonstrated totally inadequate redesign processes.
• Executing new frameworks – Also known as the interaction the board, this progression includes laying out key estimation frameworks.

11.) What are the control charts?

Ans. A control chart in Six Sigma is utilized to assess the strength of a cycle over a given period. This apparatus incorporates a diagram which expresses that whether a cycle is scaled between as far as possible. A control diagram likewise helps in deciding if an interaction should be changed or not. This saves the time and assets of the organization and recoveries the endeavors.

Further, one can likewise utilize extra Six Sigma devices like Histogram/Pareto graphs on the information created by a control diagram to assess further perceptions.

12.) What do you understand by Kano Model?

Ans. This is one of the main inquiries on Six Sigma. So be nitty-gritty with your response.
