D) Has a center line, upper and lower specification limits. 20. Which of the following statements is true about six-sigma quality? A) Six-sigma results in 3.4 defects per million B) Motorola invented the term "six-sigma quality in the mid-80s C) Provides a framework for reducing waste. D) All of the above are true. E) Only (A) and (C) are true.

Answer 1

Solution:

15: Option B
The PERT Scheduling has the three types of times which are optimistic times, pessimistic times and mean times which are used to calculate the time estimates which are then used for the PERT calculation and scheduling. Hence Option B is correct.

17: Option A
Cause and effect diagram or fishbone diagram is generally used to understand the features which are most desired by the consumers of the product. This analysis is extremely crucial and widely used in product management by product managers. Hence, Option A

19: Option A
The Pareto chart is used to analyze the defects and their causes in quality management. It is used to calculate that 80% of the defects are due to 20% causes. Hence, the Pareto chart is used to determine defects and their probable cause. Hence, Option A

20: Option D
All the statements made are correct. The six sigma has 3.4 defects per million as per the initial findings of the two employees of Motorola who invented the six sigma approach. Six Sigma is intended towards reducing the waste from the processes and improve the quality of processes. Hence, Option D is correct.
