The analysis results of this final performance-measurement
model (see Fig. 2), excluding Ma1 and Tn4, further indicate an
improved fit with the data. The model chi-square (χ2)/degrees
of freedom reduces from 1.717 to 1.705; the respective CFI and
TLI increases from .960 to .964 and from .932 to .934; and the
RMSR and RMSEA reduces from .027 to .026 and from .075 to
.074, respectively. The general form of our project-failure
forecasting model (Model 21) is summarized as follows:
