Usability capability is a characteristic of a development organization that predicts the level of usability the development projects are capable of achieving. Our experiments with the existing usability capability models indicate that current process assessment methods do not discover all relevant problems that might impede effective user-centered design (UCD) in development organizations. We propose an enhanced model where the usability capability is analyzed from three dimensions: user-centered infrastructure, implementation of user-centered practices in development projects, and business management commitment to usability as a competitive asset.
