For instance, if we sampled 800 units and found 50 defects with 5 opportunities per unit, the DPO would be as follows: Defects Per Million Opportunities (DPMO): The total defects in a sample divided by the total defect chances multiplied by 1 million. Here, C5:C24 represents the entire data range. We will be glad to know if you can execute the task in any other way. A project charter provides an overview of a project including team roles and responsibilities, financial information, goals, and constraints. For instance, if we sampled 800 units and found 50 defects with 5 opportunities per unit and multiplied this figure by 1 million, the DPMO would be as follows: Yield: The percentage of a process that is free of defects. Calculating the Mean and Standard Deviation with Excel Enter the scores in one of the columns on the Excel spreadsheet (see the example below). Well use a sample dataset overview as an example in Excel to understand easily. Step 1: Select the data that you want to use to construct the histogram. Now, insert the following formula in cell. 6 Sigma = 3.4 DPMO, 99.99966% defect-free.
