Description
The seminar begins with an examination of ISO and FDA regulations and guidelines regarding the use of statistics, especially in regards to Sampling Plans.
The pros and cons of the 2 most widely used sampling plans (ANSI Z1.4, and Squeglia’s C=0) are examined in detail, focusing especially on the weaknesses of such plans in regards to meeting regulatory requirements. Real-world examples are provided for how using such sampling plans leads to production of non-conforming product.
The advantages of “confidence/reliability” calculations are explained. Such calculations are demonstrated for Attribute data (pass/fail, yes/no data) as well as for variables data (i.e., measurements). If variables data is “Normally distributed” the calculations are extremely simple. The seminar explains how to handle “non-Normal” data, and provides the methods, formulas, and tools to handle such situations.
The seminar ends with a discussion of how one OEM manufacturer has implemented “confidence/reliability” calculations instead of AQL sampling plans for all of its clients. And suggestions are given for how to use “confidence/reliability” QC specifications instead of “AQL” QC specifications. The use of “reliability plotting” for assessing product reliability during R&D is also discussed.
Almost all manufacturing companies spend time and money to inspect purchased parts upon receipt, in order to evaluate part quality before the parts Supplier is paid. “AQL” sampling plans are used almost universally for such inspections. However, AQL plans actually provide very little information about part quality. A better way to assess the quality of purchased parts is to use “confidence/reliability” calculations. Such calculations are very easy to perform using tables and/or an electronic spreadsheet. ISO 9001 and ISO 13485 requirements include establishing “processes needed to demonstrate conformity”; FDA’s GMP (21CFR820) requires that “sampling methods are adequate for their use”. An AQL sampling plan does not provide what is needed to meet either of those requirements. FDA guidelines state that “A manufacturer shall be prepared to demonstrate the statistical rationale for any sampling plan used” — it is not possible to “demonstrate” that an AQL sampling plan ensures product quality. On the other hand, confidence/reliability calculations can be easily shown to provide evidence of product quality, and the statistical rationale for such calculations is easy to explain and demonstrate.

Additional service: (Personalized session)
We also do various similar customized events for our clients and it is specially tailored as per the client’s requirement. We arrange calls between clients and our course instructors to better understand the training requirement and accordingly a training program is designed. The course duration ranges between 90 Mins and 12 hours. Most 6 hours and 12 hours of classes are split into 2 to 3 days considering customer convenience.
We have 500+ consultants who are associated with us and each have their own specialization example GxP, GMP,GLP, 21 CFR, Computer system validation, FDA Audit & Inspection, Bioassays, Design Control, Data Integrity, FDA regulation, Clinical compliance, and almost everything that falls under Risk, Quality and Compliance arena in the Life Science industry.
If you think that your team needs some kind of boost, update or refresher in Risk management and Regulatory compliance then let me know and we can design a highly cost efficient program for you.
