Macro-Level Traceability via Media Transformations

Gotel and Morris, RefsQ ’08 3/11

Media in a simple requirements engineering scenario

ELICIT (abstract media used in elicitation) RECORD (physical or virtual media used in elicitation products) DOCUMENT REQUIREMENTS (abstract media after analysis) Text Formalised dialogue Interview by questionnaire Sound proper to domain Moving pictures Speech Formalised dialogue Printed questions (+ answers)

n paper

Sound recording

n tape (or disc)

Video images

n tape (or disc)

Other sources (operations manual + client brief) Samples from interview [unstructured text] Use case descriptions [structured text] Use case diagram [graphics and signs particular to domain]

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)
