  5. Hi Junaid Feel free to convert DPMO to DPBO (Defects Per Billion Opportunities) if you feel like. DPMO is only a unit of measurement and hence can be changed if required. Having said that, I guess a more practical question could be why did someone come up with per million and not billion. In my opinion, it is based on the highest magnitude imaginable at the time of inception. Six Sigma got started in 1980s at Motorola and maybe they could imagine million opportunities better than billion opportunities

  14. 1. Soft skills and good professional relations can help you get the data. 2.

  15. Hello Andrew You may present your case basis the transaction error % (effectiveness or accuracy ratio). Alternatively, you may also simply look at the number of transaction errors on a daily/weekly/monthly basis. This should be done only if the total number of transactions are fixed. if the total transactions vary, then looking at standalone numbers might be mis-leading.
