Acceptance Sampling

Course Description
Organizations must have some method for minimizing the total cost of inspecting from incoming, intermediate, and outgoing product inspections and at the same time not jeopardize quality of product reaching the production line or the customer.

One of the alternatives to 100% inspection of product is Sampling Inspection, also known as Acceptance Sampling. The purpose of Acceptance Sampling is to determine the disposition of goods or services (accept, reject, or screen). This is done by selecting the disposition that minimizes the cost of inspection to achieve a desired level of quality.

Who Should Attend
This course is designed for managers, engineers, or researchers who are responsible using sampling methods and wish to optimize these methods for both cost and effectiveness.

Learning Objectives
Through training, participants will:

  • Understand the risk involved in any sampling plan, namely the producer’s and the customer’s risk
  • Gain knowledge on the various performance curves of a sampling plan and their interpretation
  • Understand the advantages and disadvantages of various sampling plans
