The system for providing information on quality and reliability according to the present invention comprises: a first information communication terminal for outputting at least one of step information (A), step information (B), step information (C) and step information (D) as information on the side of a maker producing an optical semiconductor device; a second information communication terminal for outputting at least one of step information (E), step information (F), and step information (G) as information on the side of an user using the device; and an information processing apparatus connected to the first and second information communication terminals through a communication network, wherein the information processing apparatus computes a rate of change in the characteristic of the device from the steps on the maker side to the steps on the user side on the basis of information outputted from the first and second information terminals, and outputs a signal for representing an abnormality to at least one of the first and second information terminals through the communication network when the computed rate of change is out of a predetermined numerical range.
