Abstract: An information processing apparatus includes a memory and processor. The memory stores a trouble category into which a trouble occurring in a product is classified and a design-element category into which a design element causing the trouble and included in the product is classified in mutual association and store a design-element category into which a design element included in a product is classified and a design-requirement category into which a design requirement of the design element is classified in association with each other.

Abstract: A design support system includes memory, a receiving unit, and an associating unit. The memory stores information on design element classification that classifies a design element included in a product, and information on design requirement classification that classifies a design requirement required for the product. The receiving unit receives technical information regarding a design trouble. The associating unit refers to technical information regarding a design trouble, received by the receiving unit, and associates a classification item in the design requirement classification to which the design trouble belongs and a classification item in the design element classification to which a design element causing the design trouble belongs with each other, along with information on a phenomenon indicating a failure status of the design element included in the technical information.

Abstract: A design support system includes a storage unit, an accepting unit, a selecting unit, and an associating unit. The storage unit stores information regarding design element classifications into which design elements constituting a product are classified and design requirement classifications into which design requirements required for the product are classified. The accepting unit accepts technical information regarding a trouble due to design. The selecting unit refers to the technical information regarding the trouble, selects a classification item to which the trouble belongs from among the design requirement classifications, and selects a classification item to which a design element that has caused the trouble belongs from among the design element classifications.
