I'm curious how some of you control internal specifications on your products. By "internal specifications" I mean specifications that you set for your products that are used when the customer does not specify something different. And let's say you publish these specifications in a catalog, and maybe on a web page.
For example, let's say you manufacture widgets made from specialized materials and you have a catalog containing standard widgets and the specifications for them. You might say material "A" has a density of 3.45 +/- 0.2 g/cc and an insulation resistance of > 3 x 10^5 ohm-cm, while material "B" has a density of 3.85 +/- 0.2 g/cc and an insulation resistance of > 4 x 10^5 ohm-cm, etc.
You print catalogs containing these specifications and send them to your customers. Your test lab uses these specifications to approve/reject the widgets before shipment. Customers often just specify the widgets they want to buy as "material A at a size of blah x blah x blah".
How do you handle change control, approvals of the specifications and the catalogs, notifying customers and your internal people of changes, etc.

Sometimes, though, the answer is inside the box.
