Traceability from a media and transformational perspective 1 Primary source material [in multiple media and multimedia] 0.1 proxy creation : text of questionnaire to be spoken in interview 0.2 proxy use : questions spoken in interview 1.1 origination : text of responses to questionnaire 1.2 origination : recorded video images 1.3 origination : speech and other sounds from interview and work environment 1.4 origination : text and graphics in operations manual 1.5 origination : text and images in client brief 2 Conversion to text [transferring back to the ‘primary modelling language’ of natural language] – now within digital carrier media 2.1 translation : speech in recorded interview 1.3 to written text 2.2 translation : video images 1.2 to text notes of content 2.3 amplification : elaboration of interview text 1.1 with comparate use of text notes of video 2.2 2.4 revision : alterations to text of responses 2.3 with comparate use of speech recorded 1.3 2.5 merger : text from structured interview answers with text derived from any open-ended exchanges or extraneous dialogue 2.1 and 2.4 2.6 outline : text list of possible use cases from interview text 2.5 2.7 outline : text list of possible use cases from operations manual 1.4 2.8 outline : text list of possible use cases from client brief 1.5 3 Documentation [transferring to a ‘secondary modelling language’ of structured natural language] 3.1 revision : structuring of interview text 2.5 to form initial use case descriptions 3.2 revision : structuring of operations manual text 1.4 (and possible translation from graphics) to form initial use case descriptions 3.3 revision : structuring of client brief text 1.5 (and possible translation from images) to form initial use case descriptions 3.4 merger and revision 2.6, 2.7, 2.8 : use case list 3.5 merger and revision 3.1, 3.2, 3.3 : use case descriptions 3.6 proxy creation : use case descriptions 3.5 in part for later UML activity diagrams 3.7 revision: sample extractions from interview text 2.5 on basis of comparate use of use case list 3.4 4 Modelling [transferring to a ‘tertiary modelling language’ using non-textual components as the foundation for representation] 4.1 outline and translation : use case list 3.4 to use case names and diagram elements; use case descriptions 3.5 to associations in diagram 4.2 amalgamation and substitute creation : elements from 4.1 brought together in a use case diagram (or model) Macro-Level Traceability via Media Transformations Gotel and Morris, RefsQ ’08 4/11
