A system and method for performing role-based user annotation of product documentation is disclosed. The system identifies first and second roles for first and second users, respectively; causes, based on the first role, a first user interface to display on a first client device to receive a first input associated with the default document from the first user; creates a first layer of annotation on the default document based on the first input; receives a request to access the document from the second user; determines, based on the first and second roles, whether to merge the first layer of annotation to the default document for generating an output document; causes a second user interface to display the output document on a second client device; and causes the first input and the output document to be applied for document performance analysis associated with one or more entities.
