PURPOSE:To quickly measure the influence degree due to the remodeling of software by displaying the remodeling factor and the remodeling component in a matrix and then displaying the scores. CONSTITUTION:A measuring part 3 analyzes the remodeled software 1 and measures the remodeling influence degree. A matrix production part 4 produces a matrix table containing a vertical or horizontal remodeling factor column and a remodeling component column at a storage part 24. A retrieved addition point degree calculation part 6 retrieves the column of an area where the designated vertical and horizontal items cross each other on the produced or updated matrix table of the part 24 to write the numerical value of the measurement result into the retrieved column and calculates a remodeling degree from the totalized result. An output part 7 outputs those results obtained at the parts 4, 5 and 6 and stored in the part 24 to a display device 20 and a printer device 23. Thus it is possible to quickly measure the software remodeling influence degree and furthermore to obtain the same measurement result at all times.
