Only when the value is limited to the affected value, the update rule of the consistency value between the items is different. For example, when the risk value of the item A is updated from 5 to 1 from the state of FIG. 43C, the matching value from the item A to the item b can pass the risk value “5” of the item A to the item b at the maximum. Since the consistency value (risk value of item A ⁇ dependency of item A and item b / “5” is obtained as 9), the data matching unit 400 has a case where the value of one risk value has increased. Similarly, the consistency value is updated to “1”.
- the matching value from item A to item a is the matching value (risk value of item A ⁇ item A and item A) that can be passed from item A to item a by the risk value “3.33” of the affected item a.
- the matching value restricted by “5”) as a value obtained from the dependency of a / 9 is “3.33”. Therefore, in this case, in order to update the consistency value of the item A from the item A, the necessary risk value of the item A that is the minimum necessary for propagating the consistency value from the item A to the item a to the affected party in advance.
- “3.33” is obtained by a mathematical formula (consistent value from item A to item a / dependency between item A and item a ⁇ 9), and the consistent value from item A to item a when the risk value of item A decreases.
- the data integrity unit 400 does not consider the decrease in the risk value of the item A (the decrease from 5 to 3.33) that is greater than the necessary risk value of the item A, A risk value of A / necessary risk value of item A) ⁇ consistent value from existing item A to item a) is updated to “1”.
- the status of the risk value of each requirement and each element changes by virtually entering the progress into the detailed task list. Can be easily grasped. For example, by grasping these, the user can determine whether there is a work omission, necessity of reviewing the plan, or the like.
