In an unreplicated 232^323 factorial experiment, there are 8 runs (since 23=82^3 = 823=8). The total degrees of freedom are calculated as the number of runs minus 1, which is 8−1=78 - 1 = 78−1=7. However, considering there are three factors, each with one degree of freedom, and their interactions (1 for each main effect, 3 two-way interactions, and 1 three-way interaction), the correct total degrees of freedom are 7.

In Failure Mode and Effects Analysis (FMEA), the focus should be on implementing corrective actions on items that have high Risk Priority Numbers (RPN) or high severity values. The RPN is calculated by multiplying the severity, occurrence, and detection ratings, and it helps prioritize which failure modes need immediate attention.
