A manager states that his process is really working well. Out of 1,500 parts, 1,477 were produced free of a particular defect and passed inspection. a. Calculate the defects per million opportunities (DPMO). (Round your answer to the nearest whole number.) Defects per million opportunities b. Based on Six-Sigma theory, how would you rate this performance

Respuesta :

Answer:

, other things being equal?DPMO= # of defects/# of opportunities for error per unit x # of units (1,000,000)DPMO= 23/1500 x 1,000,000 or DPMO= 23/1,500,000,000 or DPMO= 1.53The 1.53 is within the target specification of Six Sigma. This performance is rated as within limits means the process is working well. The product is within the limits of the defects allowed based off the1500 parts or the “four defects per million units
