Claim One:
1. A design supporting system for an IT system, comprising: an input data part that inputs data necessary for a designing of the IT system; a throughput evaluation part that drafts a system idea meeting a design standard value for throughput, based on the data from the input data part; a reliability evaluation part that drafts the system idea meeting a design standard value for failure probability, based on the data from the input data part; a cost evaluation part that evaluates a cost of the system idea drafted by the throughput evaluation part and the reliability evaluation part; a system-idea data storage part that stores the system idea drafted by the throughput evaluation part and the reliability evaluation part and the cost evaluated by the cost evaluation part; a cost judgment part that judges whether there exists a system idea whose cost evaluated by the cost evaluation part is within an allowable range or not; and a reconfiguration part that reconfigures the design standard value for throughput, the design standard value for failure probability and the allowable range of cost in the input data part when the cost judgment part judges that there is no system idea.
