In an r2 assessment, if the responsibility for a Requirement Statement is split between the client and one or more service providers, should only the service provider scores be used?
A. No, take a blended approach to scoring and consider the responsibilities for all parties involved
B. No, you should only score the client’s portion of the responsibility
C. No, you should mark this Requirement Statement N/A as it has been outsourced
D. No, because this never happens
E. Yes, these are the most important scores
Explanation:
When a Requirement Statement’s responsibility is shared between a client and service providers (e.g., cloud vendors or managed security providers), HITRUST requires a blended scoring approach. Assessors must evaluate all parties’ contributions and assign a composite score that reflects the total control environment. This prevents organizations from over-relying on inherited provider scores without demonstrating their own responsibilities (e.g., configuration, monitoring). It also prevents dismissing requirements as N/A since partial responsibility still exists. By combining the provider’s validated assessment results with the client’s implementation evidence, HITRUST ensures a complete and accurate reflection of risk. Sole reliance on provider scores would overlook gaps in client-side processes.
