The relative importance of usability and functionality factors for the users of building information modeling software packages

BIM has been attracting attention in the architecture, engineering, and construction industries as a useful tool to prevent poor productivity, which has been a prevalent issue in these sectors. However, there are still some barriers to the faster adoption of BIM software. Functionality and usability are two critical factors affecting information systems’ acceptability by the users. This study aims to determine the interrelationships among the usability and functionality factors in the context of BIM software. For this purpose, two BIM software packages, Autodesk Revit and Allplan Architecture have been selected and evaluated. According to the relative importance preferences of end-users of these BIM software packages, functionality and usability are equally important for BIM software designs. The most critical factors are memorability and customer support/services, followed by customisability, ease of use, and learnability.
