This study draws on organizational semiotics models to analyze e-document as a composite digital sign. E-documents are increasingly becoming important in contemporary digital world. Yet research specifically focusing on analyzing it as an important information systems component remains limited. Moreover, in organizational semiotics research, semantic relationships between signs, objects and intepretants have traditionally been viewed from a single triangle perspective. This study therefore seeks to analyze e-document as a composite digital sign from multiple triangle perspective, using e-boarding pass as an illustrative case.
