doc: "greased path" for progression of inventory

[jwise]

It would be good to hear what your actual workflow is with this so I can make mine look like that. Here's a workflow that I would like to be able to capture:

• Mouser orders nn number of X1P-004 modules, and they pay me $xx each.
• I order nn*1.10 X1P-004-B02 PCBAs from my CM, King Credie, and they cost me $yy each.
• A while later, King Credie sends me a DHL tracking number.
• A while later, nn*1.10 untested X1P-004-B02 PCBAs show up on my desk.
• I get out the test fixture, and turn nn1.10 untested X1P-004-B02s into nn1.05 tested X1P-004-B02s, and nn*0.05 scrap X1P-004-B02s, and give the good ones serial number labels.
• I print Mouser labels, and package nn*1.05 X1P-004-B02s into plastic baggies and label them.
• I mail nn X1P-004-B02s to Mouser. I have nn*0.05 X1P-004-B02s sitting in a box under my desk now.

Ideally, I would like to be able to capture and log each individual step of this in smallfactory. I have ideas for how to do this, and I think that some, but not all, of these features exist yet. It would be good to have documentation for how someone uses smallfactory in a 'worked example'.

My best guess

My best guess for how to capture this in smallfactory right now is something like:

• Create a part, p_x1p-004_pcba. Add files for PCB fab. Create a release, B02.
• Create a part, p_x1p-004, that has p_x1p-004_pcba as a BOM item. Create a release, B02.
• Create a location, l_mountain_view.
• Create a location, l_king_credie.
• NOT YET: Create a workorder for Mouser's request of me. (This doesn't exist yet.)
• NOT YET: Create a workorder for my order from King Credie.
• NOT YET: Create a build for King Credie.
• When they start it, increment the quantity of the PCBA part at l_king_credie by nn*1.10.
• When it arrives here, decrement the quantity at l_king_credie by nn1.10; increment the quantity at l_mountain_view by nn1.10.
• NOT YET: Mark the King Credie build as done.
• NOT YET: Create a build in Mountain View.
• NOT YET: Something about the state of matter transition from 'untested' to 'tested but unpackaged'.
• When I scrap a bunch of PCBAs, decrement the quantity at l_mountain_view.
• When I label a bunch of PCBAs, transfer quantity from the pcba part to the root part.
• When I mail a bunch of PCBAs to Mouser, decrement the quantity here.
• • NOT YET: Mark the Mountain View build as done.
