Traceability is your ability to track materials and products. The extent of traceability is the strictest of: Customer Requirement or Industry Standard. Example, injection molded toy soldiers are not typically serialized nor is there (well, last time I really looked at one was quite a few years ago) a lot number. It's not important. There is nothing critical. Etc. On the other hand, if you buy a computer, its chassis is serialized as well and some components (including the CPU) are serialized. These in the computer example, with the customer being the final user, are really determined by industry standard with the exception of the chassis serial number which people expect in large part because of theft and insurance loss issues.
As far as a sole definition of Traceability, ummmm, well, ya got me there.
I see Accrediation in context of 'An Accreditation Board', whether for colleges or other businesses (there are 5 entries for ACCREDIT in my dictionary). The general thrust is 'To give credit or authority to' and 'to confer credit or authority on'.
I see Certification in context mostly as where one company 'certifies' another or where a company 'certifies' a product or other output where the 'certification' is their statement (promise) that something complies with something. When I think of certification I also think of a C of C which used to just be a statement of compliance/conformance (everyone asks for data now...).
Certification - in my dictionary to Certify is to 'Testify to' but there are 4 definitions - One of which is 'To guarantee the quality or worth of'. On the other hand, one definition is to 'Declare officially insane' (which may or may not apply to us for being involved in this mess...) while another reads 'To testify by formal declaration, usually written."
In so far as Accreditation and Certification go, I pretty much see them as synonomous in so far as how and what we use them for. Actually, though, I see Certification more than Accreditation. And then comes Registration. In fact, I see all these companies saying they are ISO Certified. Ummm, well maybe. They went to a registrar - which registered them. Some of us claim (mainly the English) that a company should state they are registered, not 'certified'.
I guess I confused the issue - I certainly don't see much of the 'plain English' which you were seeking in my diatribe...
