Quizplus · Accepted Answer

A First-Time-Through (FTT) rework measures both the effectiveness of the cell's standardized work and the percentage of product made without any need for rework or scrap. FTT is calculated by taking the total units processed minus rejected or reworked products and dividing the result by the total units processed.
