Desktop applications
Some work is particular to one business: the way a board is inspected, the way a part number is made up. We write the Windows program for it, fast enough to use all day and plain enough to learn in an afternoon.
A circuit board viewer for electronics manufacturing. It opens the design files, draws both sides of the board, and lets an operator find a part, mark a fault and see the bill of materials beside it.
A drawing of the kind of screen we build. The board is invented.
For a valve or a length of pipe, the part number is the specification. A generator builds the number and the description from the choices made, the same way every time, and creates the item in the ERP system.
Sums that are too particular for a standard report: who is paid what on which order, worked out from the documents and shown line by line so it can be checked.
