Again, a critical RPN value (i.e., threshold) was necessary to identify the critical project risks. However, as postulated by Carbone and Tippett (2004), there is no scientific protocol for calculating the critical value of RPM. Additionally, Mastroianni (2011) commented that such leeway in defining RPM and RS makes the risk management process for each project unique. Based on the profile of the RPN Pareto chart for Project A (shown in Figure 3), a critical RPN value of 180 was selected. This value was chosen as the maximum RPM of the current study because it was almost 1.5 times higher than that of the study by Carbone and Tippett (2004). Consequently, the critical RPM was considered to be approximately 1.5 times 125 as the critical value of RPM in Carbone and Tippett (2004). The selected critical RPM was consistent with the guidelines for selecting critical RPM put forward by Bluvband and Grabov (2009). By introducing the RFMEA technique, there was now a second attribute (namely the RPN) that could be used to prioritise the risks, thus providing a more robust prioritisation mechanism. By constructing a scatter diagram that has the RS values plotted along the x-axis and the RPN values plotted along the y-axis, the major project risks can be visually identified as those that have both an RS and an RPN above the respective critical value. The scatter diagram that was constructed for Project A is shown in Figure 4. The critical values for the RS and RPN are highlighted
