The link below is an article about the value of certification for manufacturers. It is a heavy sell for certification. In my opinion it misses the most basic benefit of certification, which is the path to getting certified.
When people ask me about ISO 9000, the simple explanation I give, “the process of certification requires you to write down your process and demonstrate that you follow the process.” The certification system does not dictate your process.
The mere action of writing down and maintaining the written procedure is the real value. In one of my blogs “Dumbest Guy in the Room", written in two parts, http://www.jagengrg.com/blog, I touch on the value of the written word and the perils of oral communication.
Writing it down allows everyone to see exactly what the author thinks is being done or should be done. Others can read the written word and identify ambiguous sections, missing information, or errors that can easily be overlooked using oral communication.
When everyone is carrying the information in their head’s via oral direction I can guarantee there is more than one interpretation. I would venture to say you will have as many interpretations as you have people involved.
When written procedures do exist but do not come under the scrutiny of a certification body, it is very common for procedures to become stale, be incomplete, rely on undocumented knowledge, and for steps in the process to be missed from time to time.
The subject article closes with a realistic assessment of the value for certification. “Is having a certification the end-all-be-all of manufacturing? No. However….”
You reach the "however" stage, not my hanging the certification on the wall, but the process for obtaining it.
