What is a primary benefit of document analysis in business analysis?

Document analysis is a critical component of business analysis because it delves into existing documentation to extract valuable insights and information that may not be readily apparent. One of the primary benefits of this method is its ability to uncover hidden information. Through a thorough review of documents such as reports, emails, manuals, and meeting notes, analysts can identify discrepancies, gaps, or opportunities that may not have been communicated explicitly in verbal discussions or meetings.

This process allows business analysts to gain a comprehensive understanding of the context and history surrounding a project or issue, revealing perspectives that stakeholders may not have considered. By examining how decisions were made, tracking changes over time, and noticing patterns within the documentation, analysts can often bring to light critical factors that could influence the outcome of the business process or project.

The other options present different ideas that do not highlight the primary benefit of document analysis. For instance, real-time observations pertain more to direct observations during live interactions, while minimal time investment suggests a lack of thoroughness that is typically not the case in document analysis. Focusing solely on quantitative data neglects the qualitative insights that documents can provide, which are often essential for a holistic understanding of business needs.
