Inspections, Decisions and Approvals add time to the process and, unfortunately, they are not always the best methods of insuring quality. Identifying where Inspections, Decisions or Approvals occur in the process and assessing the value of those steps provide streamlining opportunities.

    Hello. I’m a quality engineer in EMS and I have big issues with the cosmetics of a part. I’ve tried with limit samples, pictures, measurements. But nothing works because the deffects are different for every batch. I have to make inspection criteria for each batch. This is a huge resource consuming. Could you be so kind to advise how can I improve the inspection and make it more efficient? Thank you.

    • Hi Noemi!
      Keep in mind that an inspection step downstream is put in place to catch problems created upstream. The goal in Lean Six Sigma is not to get better at inspection, but to do some root cause analysis to understand what’s causing the defects in the first place. The ultimate goal is to reduce or eliminate the need for inspection since that’s rework. Inspection and rework are both wasted labor. This sounds like a good DMAIC project to tackle.

      Good luck!
