Explanation:
Consecutive points on a control chart that are above or below the mean or if a point exceeds a control limit indicate an abnormal trend in the process and must be investigated.

Explanation:
This technique is a method of analyzing design reliability. A list of potential failure modes is developed for each element, and then each mode is given a numeric rating for frequency of occurrence, criticality, and probability of detection. These data are used to
assign a risk priority number for prioritizing problems and guiding the design effort.

Explanation:
The quality policy includes the overall intentions and direction of the organization with regard to quality, as formally expressed by top management. If the performing organization lacks a formal quality policy or if the project involves multiple performing
organizations, as in a joint venture, the project management team must develop a quality policy for the project. The quality management plan then describes how the quality policies will be implemented.

Explanation:
Quality assurance is a managerial function that establishes processes or procedures in an organization or project to assist in determining whether quality standards and operational definitions are being met. It is the application of planned, systematic quality
activities to ensure that the project will use all processes needed to meet requirements and is performed throughout the life of the project. Quality audits are a tool and technique to use.

Explanation:
Deming is known as a quality pioneer. His approach to quality is not only statistically based but focuses on what management’s responsibilities should be with respect to quality. His Fourteen Points for management are goals of quality for transforming business.

Explanation:
Statistical sampling uses part of a population to draw conclusions about the total population. It is a well-proven technique that can significantly reduce the cost of quality control.+

Explanation:
When the results of a sample of items measured falls within three standard deviations and that sample is representative of the entire population, you can assume that more than 99% of all items fall within that range. This generally accepted range of results has
been used by quality control professionals through the years. Six sigma is a program started by Motorola that, from a statistical standpoint, indicates a quality +standard of only 3.4 defects per million.

Explanation:
The information obtained from a quality audit can be used to improve quality systems and performance. In most cases, implementing quality improvements requires preparation of change requests.

Explanation:
In perform quality assurance, the interrelationship diagraph can be used as a quality management and control tool. It may be developed from data generated by other quality tools such as the affinity diagram, the tree diagram, or the cause-and-effect diagram. It is
an adoption of relationship diagrams.
