Both the Online Projection System (OPS) and the Quality and Production
Management (QPM) systems are KFC initiatives, similar to smart kitchen products,
that assists store operators in maintaining an appropriate inventory of cooked food,
ready to serve, so that customers do not have to wait for their orders. The computer
system performs real-time monitoring of sales, product inventory, product "in process"
(being cooked), etc., and consults a history of past sales data in order to project
expected sales. Based on projected sales and current inventory, the system prompts
the restaurant staff on how much product to cook and when.

In order to track how much product is being cooked and placed into inventory, the
OPS/QPM system communicates directly with the kitchen equipment via an inhouse
ZigBee wireless network. It can directly query each fryer, for example, to discover its
current operating status: off, on, melt mode, cook mode, currently cooking, etc. Also,
the fryer reports the start and end of each cook cycle, as well as which product is
being cooked. For some products, like strips, the control asks the user to specify
precisely how many pieces are being cooked, and then passes that information on to
the OPS/QPM computer. For other products, like various loads of bone-in chicken, the
OPS/QPM system is pre-programmed to know how many pieces to expect for the
various standard loads.

The Digi ZigBee radio is hard-wired to communicate with the fryer's control board but
uses wireless to interact with the operator's network. To facilitate two way
communication between the Digi radio and fryer, the Digi radio must be properly
installed, powered on, and the fryers communication software enabled. In addition, to
facilitate communication between the fryer and the virtual (network) environment
(Smart Kitchen), the network must see the Digi radio and allow it to join the network to
enable seamless two way communication.

as an open global standard to address the unique needs of low-cost, low-power
wireless M2M networks.
