Parts Numbering Scheme

We are a small company, and we would like to implement a better components
numbering scheme.

The parts numbers need to go into our accounting system and on parts lists,
build lists and some schematics, so we don't want them to be too long.

Letters and digits are OK, but each must start with a letter. Sort order is
a consideration, because computers sort strings from left to right, often in
ascii or similar order. That means each character position has significance
and it might be best if every part had the same number of characters.

The storeroom must be organised by part number, so that we can work
systematically to find the correct shelf, container, then envelope or reel
inside the container. We need to store similar parts together in the
storeroom, to make the most of the containers. For example, SMD resistor
reels are stored together, with a number of different resistor values in
each container. This means SMD resistor part numbers must form a sequence,
though not necesarily in order of ohms value.

A part number should at least tell roughly what kind of part it is - SMD
resistor, leaded electrolytic, etc, so that means the leftmost characters
should carry that info so the sorted list is by part type.

Now, does anyone have a system like that ? Or a different or better system
?

thanks
Roger Lascelles
