Yes, I agree. I guess I have been looking at the verbal component, there cannot be any control or log when its all verbal.
We have a form integrated with our procedures that provides this mechanism "Project I/O Notes (Meeting Minutes)" where important input, decisions, characteristics, and change requests can be noted. There is a stunning resistance to using this form because it is 'extra work' compared to cornering someone in the hall on their way to the bathroom/important meeting and rambling on about this or that.
We also have written standards in a wiki that anyone can edit, to record as much of the "shoulda known" tribal knowledge as possible.
So I think we have multiple ways to address this (record, document), but its not being utilized in favor of verbal comunication.
After you've been burned a few times, you develop an acute sense of when something should be expressed in writing. Part of what I've learned is Trust No One. A brief illustration:
I once worked for an OEM, and later worked for a machining job shop that supplied the OEM. I walked into the owner's office one day and found him examining a part and drawing that I was well familiar with, and I knew it would be trouble. It was a "finesse" part, one that was not suited to the present situation. I'd had many struggles with it on the other end. I told the owner as much, and advised him to not accept the job. He didn't listen, and the disaster I feared began to take place.
There was a feature of this part--a sealing surface--that had to be .005" to .007" wide, and bear no nicks or scratches. In addition to machining, it had to be passivated, which necessitated special racks and extremely careful handling. The first lot of parts through our shop had surfaces that were mostly awful, and as much as .005" over the UTL. Much sorting and hand-lapping (on a surface plate) was done, but it couldn't help the dimensional problem, which was not reworkable. I was told to contact the customer and see if I could get them to buy off on the dimensional issues.
My contact was the person who had replaced me as quality manager for the OEM, and who had worked for me, and who (I thought) was a good friend. I explained the situation to him, and he said that he'd talk to the design engineer (whom I also knew) and see what he thought. He came back to me the next day and told me that they would accept parts that were as large as .010", or .003" over the UTL. More sorting was done (which involved measurement under a microscope with a reticle). The "good" parts were then shipped. Two days later, I was informed that the parts had been rejected due to an oversized sealing surface. I called the QM, who (A) said that they could not accept any out-of-tolerance parts and (B) summarily denied having told me otherwise. Not only that, he told my boss, in writing, that I must have made the whole thing up because he would never have given such permission. I called the design engineer, who told me that the QM had never even talked to him about the issue until the over-tolerance parts had arrived.
There's an old saw in journalism about fact-checking: "If your mother says she loves you, check it out." I would add to that: ...and get it in writing.":
