Create a Sigma Calculation Worksheet

110 Sigma Calculation Worksheet can be determined several ways. The steps below use thes forts at the end of a process (usually called, appropriatele Sigma levels of a process can be determined several ways. The ste method, based on number of defects at the end of a proces "process sigma"). (process) STEP 1. Select the Process, Unit, and Requirements > Identify the process you want to evaluate: What is the primary "thing" produced by the process? What are key customer requirements for the unit? (unit) (requirements) STEP 2. Define the "Defect" and "Number of Opportunities" Based on the requirements noted above, list all the possible defects in a single unit (e.g. late or missing data, wrong size, delivered to wrong address, etc.). Be sure the defects described can be identified objectively. (defects) How many defects could be found on a single unit?_ Copportunities) STEP 3. Gather Data and Calculate DPMO Collect end-of-process data (units counted) (total defects counted Determine total opportunities in data gathered: Counted x Opportunities = __ (total opportunities) Calculate defects per million opportunities: (# Defects Counted + Total Opportunities) x 10 = (DPMO) STEP 4. Convert DPMO to Sigma Use simplified conversion table and note estimated sigma here: NOTES: 1. The table will give you a very rough range of your vary significantly based on the accuracy of your data and the number identify on a unit. Figure 10-11.
