What are some of the common formulas used in six sigma?


In addition to the statistical formulas, there are some basic formulas that everyone should be familiar with. They are:

  • Proportion defective = [number of defectives]/[number of units].

  • Final yield (noted as Yfinal) = 1 - Proportion defective.

  • Defects per unit (DPU) = [number of defects]/number of units].

  • Defects per opportunity (DPO) = [number of defects]/number of units number of opportunities].

  • Defects per million opportunities (DPMO) = DPO 1,000,000.

  • first pass yield = 1 - [number of units reworked]/[number of units input].
