A method for reviewing a modified source program includes extracting review-requiring points to be reviewed, by comparing a pre-modification source program as a source program before a modification and a post-modification source program as a source program after the modification, storing a review history indicating whether each of the review-requiring points extracted at the extracting has been reviewed or is unreviewed, outputting information of the review-requiring points extracted in the extracting, associated with the review history stored in the storing and indicating whether each of the review-requiring points has been reviewed or is unreviewed, to a predetermined output unit, and updating the review history stored in the storing when receiving from a predetermined input unit that the review-requiring point outputted as unreviewed by the predetermined output unit has been reviewed.
