The Rhombus Factory Information System is a modular production control system for medium to high volume manufacturers.
It is unusual in that it has been built up from a shop-floor data collection system, rather than down from an accounting system. This means that it has modules to handle many tasks on the shop-floor which you do not get in other software packages.
Large companies use it as a Manufacturing Execution System.
Small and medium sized companies use it to run their businesses.
