PURPOSE

This Marshall Procedural Requirements (MPR) provides a consistent method for applying statistical techniques used in data analysis or interpretation, and specifically in establishing, controlling, and verifying process capability and product characteristics, when the use of statistics is required or statistics are otherwise employed by an organization.

APPLICABILITY

This MPR applies to Marshall Space Flight Center (MSFC)/Michoud Assembly Facility (MAF) personnel and activities, and to MSFC/MAF contractors and resident agencies to the extent specified in their respective contracts/agreements. "Contractors" as used in this paragraph includes contractors, grantees, Cooperative Agreement recipients, and Space Act Agreement partners or other agreement parties.

This MPR is applicable to organizations that identify a requirement for the use of statistical techniques. Statistical Techniques could be used in any case in which data analysis or interpretation is useful, and specifically could be used when establishing, controlling, and verifying process capability and product characteristics. According to the nature of the product and depending on the specified requirements, statistical techniques may be used to support:

Design verification (e.g., reliability, maintainability, safety);

Process control:

• Selection and inspection of key characteristics

• Process capability measurements

• Statistical process control

• Design of Experiments;

Probabilistic Risk Assessment (PRA);

Inspection - matching sampling rate to the criticality of the product and to the process capability. It is important to note that whenever an inspection sample size less than 100%, is determined, and occasionally when apparent 10 percent sampling is used, the use of statistics is implied.
