"I'm pleased to tell you that F. M. Howell has remained a Six Sigma Supplier to our pharmaceutical facility for at least
the last two (perhaps even three) years. While we don't formally measure this, I can tell you with NO nonconforming materials received by us in many, many thousands (millions?) of cartons received, your organization has certainly achieved and maintained a Six Sigma quality level with our company. Six Sigma is defined as 3.4 defects per one million opportunities. This quality of product attests to the focus and professionalism of your operations staff as well as company management. Thank you.
The result is that our work with Howell is a pleasure; it's easy, seamless and efficient, both in cost and time. We appreciate having F. M. Howell & Company as a supplier—we wish we had more like you. Three years ago you were one Six Sigma supplier in a field of six for our manufacturing site. Today you are one in a field of two for our building. We appreciate F. M. Howell & Company maintaining this standard of excellence."
