**4.2.6 Integrated Cost/Schedule Risk Response Variances**

It is possible to examine the total change in the efficiency of the response strategy for the cost/schedule/risk by integrating the CRRV and SRRV in a quadrant as shown in Figure 2. The integrated chart of the cost/schedule risk response variances can be analyzed as follows. First, if the CRRV and SRRV are both greater than 0, it shows that the efficiency of the response strategy is excellent in both cases. Second, if the CRRV is greater than 0, but the SRRV is less than 0, it shows that the efficiency of the strategy of the SRRV is poor. Third, if the CRRV is less than 0, but the SRRV is greater than 0, the efficiency of the CRRV is poor, but the efficiency of the SRRV is good. Fourth, if the CRRV and SRRV are both less than 0, the efficiencies of the CRRV and SRRV are both poor.
