Playback Technique using a Temporally Sequenced Cognitive Artifact for Knowledge Elicitation

Abstract

Developing effective computer support for work done in complex socio-technical environments requires understanding the necessary expertise for the work. Preserving and examining cognitive artifacts, such as notes, made by the practitioner while working is valuable in ensuring an accurate understanding of the required expertise. However, how the notes are analyzed for discovery needs to include the fact that a note artifact has a temporal dimension. Exploiting the temporal dimension of note-making reveals the sequence of the practitioner's thought process and relays what was considered important at points in time. This paper focuses on the development of a methodology to unfold a novice practitioner's task performance in order to reveal the novice's process to an expert so that future computer system requirements can be identified. An important key to the unfolding was the notes pages. Several methods of using the note sheet artifacts were explored and the resulting methodology is described.
