What type of assessment can determine if a system contains PII, whether a privacy impact assessment is required, and if any other privacy requirements apply to the IT system?

Privacy threshold Assessments

Explanation:

Privacy threshold Assessments (PTAs) are made up of simple and well-tailored questionnaires that are filled by system owners and sent to an organization's privacy office that will review and approve them.

PTAs are very valuable for collaboration and communication between organization's departments, with emphasis on business processes and data in those departments and the probable connections with persons including the use of PII.
