Six Sigma Project – Reducing Laptop Returns – COMPLETE


Acme Laptop Company has been manufacturing and selling laptops for nearly a dozen years. They successfully launched two flagship models, the DEVICE, and the GADGET, keeping costs and after-service warranty expenses low and in control.

After launching their third model a little over a year ago, the WIDGET, their quality assurance team quickly summoned help from their in-house Six Sigma Black Belt as they could not figure out why there were so many customer returns in the first year since the product launch. In addition to the customer pain, the company was incurring hundreds of thousands of dollars of additional, unbudgeted expenses.

All design validation and mistake-proofing deviceswere put in place and all the WIDGET laptops met the stringent final QC requirements such as did the previous models but the WIDGET continued to fail early into the warranty coverage period, incurring additional costs for replacement units and freight to get the replacements to the customers.

How did the Six Sigma Black Beltapproach the problem? What findings came about? What permanent corrective solution was put in place?
