What Is ValidRisk?

ValidRisk is the most practical, integrated, empirically valid project risk quantification software available.


ValidRisk is a result of the alliance of Koff&Guerrero Consultants (KGC) and John K.Hollmann (Validation Estimating LLC) who brought together their experiences and expertise to create a unique, innovative and proven Project Risk Quantification product on a cloud platform.

ValidRisk is the unique risk analysis software that uses a hybrid method to support contingency and reserve determination in a way that is realistic, practical, risk-driven, integrated and empirically sound.

ValidRisk employs a hybrid method that combines parametric modeling of systemic project risk along with the time-tested expected value method with Monte Carlo simulation for project-specific risks (i.e., risk events). The hybrid method is documented in AACE® International Recommended Practices and are fully explained in the book written by John Hollman titled “Project Risk Quantification”.
