How Large A Sample Do I Need?

(Webinar length:  1hr 23min)

Overview:

Sampling is an essential element of process and product development as well as control of manufacturing processes. The decision is made to sample a process, vessel or incoming material to make decisions regarding the sampled material immediately raises the question “How Large a Sample Do I Need?”

This webinar provides some practical and useful answers to this question.  Methods for determining appropriate sample sizes in raw materials acceptance, finished product release, process and product development experimentation and process monitoring for process stability and capability is discussed. A comparison is made of the square root (n)+1 sampling rule with the ANSI Z1.4 sampling system for process monitoring including incoming raw materials, in-process manufacturing and finished product. The value of a systems approach to sampling and practical tips, traps and guideline for sampling is discussed. The presentation includes portable methods for making power calculations for experimental design. The concepts and methods involved are introduced and illustrated with case studies and examples.

 What you will learn:

  • Principles for developing useful sampling plans and procedures
  • When “Square Root (n)+1” is a valid sampling plan
  • Creating a process sampling system using ANSI Z1.4 Sampling Plans
  • Sampling plans for monitoring process stability and capability
  • Practical power calculation procedures for determining appropriate experiment size
  • Plans for sampling tanks and blenders
  • How to use sampling data to get early warning of impending process problems
  • Tips, traps and guidelines for developing successful sampling plans

Who will benefit from this webinar:

  • Executives
  • Department Managers
  • Quality Engineers
  • Research and Development Scientists
  • Biologists and Microbiologists
  • Process and Manufacturing Engineers
  • Quality Assurance Personnel
  • Supply Chain Professionals
  • Accounting Professionals
