Abstract: An information processing apparatus includes the following elements. A first receiver receives a first QFD chart having axes, items formed in a hierarchical structure being appended to each axis. A second receiver receives a second QFD chart different from the first QFD chart. An integrating unit integrates the first and second QFD charts into a third QFD chart. Concerning axes of the first and second QFD charts having the same axis name, if part of an item name in a highest hierarchical level of items on the axis of the first QFD chart coincides with that of the second QFD chart and if remaining parts do not coincide with each other, the integrating unit sets the consistent parts as an item name in a highest level of the third QFD chart and sets the inconsistent parts as item names in a second highest level of the third QFD chart.

A second calculator calculates a correlation score between the second item and an item associated with an adjacent axis and determines the calculated correlation score between the item associated with the adjacent axis and the first item. A second extracting unit compares the correlation score with a predetermined value and extracts a third item related to the first item. A display unit displays the first item, the second item, and the third item in a mode different from a mode of the other items.
