The “re-estimate” button 96 is a button for instructing re-estimation of the add-on function up to the budget as a result of the change of the rank of the add-on function candidate.

FIG. 28 is a flowchart showing in detail the processing procedure of the add-on function modification in step 111 of FIG. In step 701, the add-on function candidate correction unit 6
Displays the add-on function modification screen 30, and repeats the following processing until the user gives an instruction to end assuming that the result of the following estimation is satisfactory. In step 703,
The upper limit value-budget is calculated from the budget stored in the memory and the upper limit value. For the add-on functions arranged in descending order of the evaluation value in step 407, the add-on function candidates within the range of budget ± (upper limit value-budget) are calculated. Steps 705 and 70
Step 7 is repeated. In step 705, an effect is displayed in the “past block effect” column corresponding to the add-on function having a high block effect on the add-on function modification screen 30, and the addition or deletion of the add-on function candidate is accepted. The addition is to input a check in the function change 93 column of the add-on function candidate below the budget line, and the deletion is to delete the check in the function change 93 column of the add-on function candidate above the budget line. For example, assume that the add-on function candidate to be considered is A, and the effect of the block including A is high. Assuming that the block includes B and C as the add-on function candidates other than A, the add-on function candidates A, B and C are regarded as one unit and the evaluation value = (A target achievement degree of A + target achievement degree of B + C Is calculated) / (man-hour of A + man-hour of B + man-hour of C). In step 707, when the "change order by block" button 95 is pressed, the entire add-on function candidate is rearranged in the descending order of the evaluation value and displayed again. When the “re-estimate” button 96 is pressed when the modification examination of all the add-on function candidates to be examined is completed, the estimation result of the man-hour for the add-on function up to the budget is calculated in step 709. That is, the bold line 94 separating the add-on function candidate above the budget line and the add-on function candidate below the budget line is displayed again. In this way, all the add-on functions above the budget line are checked, and when the processing end is instructed, the add-on function is determined. At this time, there may be a check in the add-on function below the budget line and above the upper limit line. If step 107 is executed again for the determined add-on function,
Business flow can be updated.
