The MAJOR reason to classify information assets is

Maintaining a current inventory and catalog of information assets is a necessary prerequisite for classification, but not the primary reason for performing the classification itself.

Classifying information assets helps an organization understand the inherent value, confidentiality requirements (sensitivity), and operational importance (criticality) of its data, systems, and intellectual property. This understanding is fundamental for implementing appropriate security controls and protective measures that are commensurate with the asset's significance and potential impact if compromised.

Establishing Recovery Time Objectives (RTOs) is an outcome derived from understanding an asset's criticality, which is determined through the classification process, but classification has a broader purpose beyond just recovery planning.

Categorizing data into groups is the *process* of classification; the major *reason* for undertaking this process is to assess the sensitivity and criticality of those groups.
