This study targets a particular theoretical gap within the “nano-level” of the IT productivity paradox discourse that is concerned with challenges in identifying a productivity increase in operations that are conducted with the support of IT. The objective is to find out how IT may be used to increase the productivity of a white collar professional, such as an accountant, an architect, a recruiter, or a journalist. The focus set of this study is on the lack of empirical data with regards to how IT-use contributes to productivity gains at the individual and task level. The proposed study differs from earlier research on the relationship between computerization and productivity by focusing on how IT-use can enhance information worker productivity based on the common set of information-processing functions from both descriptive and normative research approach perspectives.
