Exploring the Dimensions and Effects of Computer Software Similarities in Computer Skills Transfer

Computer software similarities play important roles in users’ skills transfer from one application to another. Despite common software attributes recognized in extant literature, a systematic understanding of the components and structure of software similarities has not been fully developed. To address the issue, a Delphi study was conducted to explore the underlying dimensions of software similarities. Inputs gathered from 20 experienced Information Systems instructors show that Computer Software Similarity is a multi-dimensional construct made up of interface similarity, function similarity, and syntax similarity. Each dimension consists of software attributes that users perceive to be transferable in learning new applications. A field study was carried out to test the impact of the construct. Results from a survey on students’ learning two software applications confirm the expectation that Computer Software Similarity facilitates the students’ skills transfer between the applications. These studies provide a basis to better design training programs for improved training performance.
