Over the last 20 years, the knowledge audit and map have been acknowledged as important tools in helping to identify and visually represent the knowledge present in organizational contexts. Despite this recognition and the availability of theoretical material, there has been a dearth of literature relating to the application of these tools. Consequently, a number of methodologies based on KM practice and research emerged in the early 2000s; several of which still inform the knowledge audit and map processes today. This paper revisits and extends research carried out by the authors in 2004 to present how this work has been expanded further through the incorporation of ensuing developments in the field with a view of continuing the development of knowledge auditing and mapping approaches. As such, a detailed methodology based on a recent case study is presented, including comparisons between the two methodological approaches, a rationale for the consequent modifications to the original case methodology and concomitant benefits for the amended approach.
