1. An information collection device comprising circuitry configured to:
accumulate, in a database, a control signal of a local device having a motor, the local device being a part of a production system of one or more workpieces, the control signal including internal information of the local device generated during operation of a plurality of processes;
accumulate, in the database, program information on a program for operating the local device to execute the plurality of processes;
identify a part of the program corresponding to one process of the plurality of processes based on a predetermined extraction condition and the program information;
extract from the control signal accumulated in the database, a signal set that is accumulated during the one process of the plurality of processes and that is associated with the part of the program in the database; and
generate an evaluation result of the one process based on the signal set.
