Adequate Inspection for Defective Products in Photography Sector and Determining Inspector Reliability by Using Juran - Melsheimer Plan

General inspector errors may consist of accepting defective units of product or rejecting good units of product. It can be said that the human element in the inspection process is the inspector himself, who contributes to inspection errors. Besides some other errors like use of wrong spesifications, wrong measuring instrument, improper filling of documents etc., in some cases the effects of inspector errors are so extensive that there is need for measuring the extent of errors with a plan for measuring inspectors’ accuracy and control the effectiveness of inspectors. Under this plan the check inspector re-examines the inspected product both the accepted and rejected units. Although the check inspector also makes errors, these have only a secondary effect on the inspector’s accuracy. In this paper, determining inspector reliability by using the Juran Melsheimer plan is explained with the help of a problem from the photography sector. (
