#How to calculate ppm quality full#

Entering defects, number of units and number of opportunities per unit (the number of specifications that need to be controlled for quality for each unit, defect opportunities per unit) results in the full output of the calculator, including DPM, percentage of defect units, and rolled throughput yield on top of the outputs covered so far. Entering the number of defects and total opportunities for a defect to occur outputs the control level (sigma), yield, percent defects and DPMO. The minimum required input is DPMO in which case the six sigma calculator (not to be confused with a sigma notation calculator!) outputs the corresponding sigma level, standard yield and percent defects.

percentage of defect units from the total production.

defects per million opportunities (DPMO, a.k.a.

percentage of defects from total opportunities of the process to produce a defect.

yield in terms of acceptable products or services delivered (rolled throughput yield, RTY).

yield in terms of opportunities which did not result in a defect (standard yield).

sigma level of the process (shows how well it is controlled relative to acceptance standard).

Depending on the input, the output consists of:

This sigma calculator can be used to estimate the sigma level of a process (of producing units or delivering a service) based on the ratio of defects it results in.
