Imagine you are a detective trying to piece together what really happened at a crime scene. You would not just ask one witness and close the case. You would look for fingerprints, talk to several people, maybe review security footage, and check phone records. A knowledge audit is similar: you are investigating how knowledge flows, where it hides, and what it’s worth inside an organisation. If you rely on just one source, your conclusions will be shaky. This chapter shows you how to gather evidence in a way that makes your audit findings solid, trustworthy, and useful for making real decisions.
