A process of establishing an operating environment of a board work system operable by a plurality of operators who are assigned in turn to operate said system for achieving at least one predetermined work on a circuit board, said board work system including (a) a plurality of mode-changeable devices, each device having a plurality of different modes and changeable between said plurality of different modes and (b) a control device which controls said plurality of mode-changeable devices and receives operator ID data of each one of the operators so as to recognize which one of the operators is currently assigned to operate said system, said process comprising:
- a suitable-mode-establishing-data preparing step of preparing suitable-mode establishing data representative of one of said plurality of different modes which is to be established in each of all said mode-changeable devices as the operating environment during operation of said system by each one of the operators;
- a suitable-mode-establishing-data storing step of storing said suitable-mode establishing data in a suitable-mode-establishing-data storing portion of said control device;
- and
- a suitable-mode establishing step, which is implemented by said control device, of establishing one of said plurality of different modes in each of all said mode-changeable devices, on the basis of said suitable-mode-establishing data and according to said operator ID data received by said control device.
