Combining agile and human centered design approach for usability testing

Abstract

Agile was proposed by user interface developers as the faster and more effective way on how to transform user needs into the final system. The goal of this research was to seek how to integrate usability and interaction design methods into agile development process by using human centered design approach. To conduct the research efficiently and successfully, the prototype model was developed using agile and human centered design approach and tested. The research used comparative method to determine the different kind of usability results for software developed in agile and prototype model which was developed using agile with human centered design. As well, the data for this research was obtained from usability testing tool entitled "load complete". The research results showed the developed model counted 26% for total load page time compared with agile model which it counted 74%, the results showed that response time took 19% for developed model where agile model took 81%, by comparing that response time was high for agile software as compared with developed model. The results also showed that agile model used 99% CPU usage more than developed model which it used 68% CPU usage. The results demonstrated that the developed model can improve the efficiency and usability of interaction in software development process.
