# Construction Management Risk System (CMRS) for Construction Management (CM) Firms
## 4 CRMS Development
### Verification of CRMS
#### 4.2.2 Verification of Expected Effect by Applying CRMS  
Field operation managers of different CM firms were surveyed in order to verify the practical applicability of the CRMS and to prove that it can effectively be used to solve field operation management problems faced by CM firms. The CRMS proposed in this study is aimed at improving the systematic risk management processes and further at improving business effectiveness and productivity. Thus, the expected effectiveness of this system has been examined by providing explanatory videos and explanations to field operation managers from 15 firms (15 survey copies were distributed and collected).  
The CRMS assessing categories were \"Ease of use\", \"Adequacy of risk response measures\", \"Adequacy of system architecture\" \"Degree of completion of system\", and \"Practical applicability\". These five categories were evaluated on a Likert 5-point-scale (1: Very low; 5: Very high). Table 3 shows the results of expert verification.  
The average rating of the system was 4.09, and the average scores for each evaluation category were 4.27 (practical applicability and adequacy of the risk response measures), 4.13 (degree of completion of the system), 3.93 (adequacy of the system architecture), and 3.87 (ease of use).
