This article presents a systematic approach for reconceptualizing the system usage construct in particular nomological contexts. The approach comprises two stages: definition and selection.
Two concerns that need to reconceptualize system usage: no theory and poor-to-no validation
A staged approach for reconceptualizing system usage:
A two-step method for selecting measures of usage in future research: system usage can be attributed with a precise definition, but the definition refers to a broad range of content, only a subset of which will be relevant in a specific study.
Define the distinguishing characteristics of system usage and state assumptions regarding these characteristics.
==> Selection stage:
Choose the best measures for the part of the usage activity that is of interest.
Step 1: Structure. Select the elements of usage that are most relevant for the research model and context.
Step 2: Function. Select measures for the chosen elements that tie to the other constructs in the nomological network.
The staged approach advanced in this paper helps to clarify the meaning of system usage and the range and dimensionality of past usage measures.
