Documented rationales are required for each HITRUST CSF mapping. These rationales are shown alongside each mapped HITRUST CSF requirement to PSD searchers / users. The purpose of rationales is to help searchers understand how the offering helps support achievement of the control. This is a required field and is especially important in defining how an offering can solve a searcher’s problem. This field is also important in defining the specific aspects of a broader HITRUST CSF requirement statement that the offering is meant to solve.
