Your ISO 9001 Quality Management System documentation
ISO 9001 documentation structure is outlined in the ISO 10013 Standard – Guidelines for Developing Quality Manuals. This standard recommends using a three-level structure. In practice, many companies use four-level documentation model that includes records. 4-level quality management system is shown below:
Quality Manual – level 1
Procedures – level 2
Instructions – level 3
Records – level 4
Interestingly, how are we going to start our quality manual without knowing what standard this manual is for? The quality policy supposes to define it. The policy defines what standard or standards, a company wants to comply with. If you like this idea, your QMS will contain five levels as in the following list:
Quality Policy – level 1
Quality Manual – level 2
Procedures – level 3
Instructions – level 4
Records – level 5
ISO 9001 – Naming your documents
Companies use various approaches to titling their manuals, procedures, instructions, etc. For example, one of my customers titled their quality manual as “Quality Management System Quality Manual.” This very descriptive title does define the document, but does not appear to be efficient.
It is common in regulated industries, such as medical device manufacturing and airspace to call 2nd-level documents Standard Operating Procedures or SOP. Do these companies have “Non-standard Operating Procedures”, so long these titles differentiate them? Since a short name identifies a document, I really cannot justify long-named documents. I preach management system optimization and reduction of waste in all elements of management systems. I invite you too not to make things more difficult than they have to be to deliver the message.
Numbering your documents
No standard prescribes to give a part or a document its number. It is an industry standard to give a document or a component its name, number and a revision level. Similar to part titles that we discussed above, document numbering conventions are often also may be optimized and simplified.
One of my clients runs a small company of some 120 employees. Their documentation control procedure prescribed two numeration systems that dependent on the type of a document. QMS documents had numbers like XX-XXX, and production parts required part number format as XXXXXXX-XXX. One of the drawings had a number 000048-002. Folks on the floor called it “four-eight.”
One can certainly use these long-long numbers, but is it practical? So far I did not meet a single company that could justify such an approach. When I audited this client, the organization had less than 250 documents. There were no indications that the company will significantly grow. Therefore, to use document number format allowing hundreds of thousands of numbers could hardly be justified. The most unreadable part numbers I had to deal with was at a mid size company with 13-digit alphanumeric part number format! Try to write those in your audit report!
If you are designing and building a Trident-class submarine, a MIG-27 jet fighter or an international space station, you, most likely, will need millions of parts, so a long part number format would be needed and will make sense. Otherwise, save yourself the trouble of reading all those zeros and make your numbering system practical. One of my customers, who won my “The Best Part Number” Grand Prize, numbered their documents as 101, 102, 103, and so on. Short and sweet!
There is another opportunity for improvement of many QMS – part number designation. Many companies relate a document number to a document type. For example, 20-xxxx indicates a procedure, 30-xxxx indicates a drawing, SOP-xxxx indicates a standard operating procedure, etc. My practice with a few QMS that used designation approaches showed that “no designation” systems are more practical. Several QMS that used designation I have worked with have failed. Not long ago, one of my clients mentioned that they ran out of range in their document numbering format. The QMS initially permitted for identifying suppliers through a two-digit identifier within the part number. While the company grew, the number of supplier increased beyond expectations and eventually the company needed more than 99 suppliers. This resulted in the document number format to being able to support new needs.
There are good news and bad news. The bed news is that designation systems can fail. The good news is that there is another way of dealing with document numbers: no designation at all! Using such systems, you give documents or parts sequential numbers. Going further, isn’t the part title the best identifier of the part? One company I know did not use part numbers at all – their procedures and instructions were simply identified by titles and a two-digit revision level.

ISO 9001 Controlling formsOne of the controversial issues with interpretation of ISO 9001:2000 Standard and others is control of forms. Many companies, by some reason, treat forms differently than documents, leaving them not controlled. Per ISO 9001:2000, element 4.2.3, "Documents required by the...
