Risk Profiling
Pipeline Risk Assessment—Risk Profiling In earlier installments of this column, we introduced the concept of pipeline risk assessment Essential Elements (EE’s). That guideline is a list of ingredients that must be included in any pipeline risk assessment before that assessment can be considered complete. Following these guidelines helps to ensure a technically sound risk assessment […]
