Function Evaluation of the Usability on Printer(2) 

－A Method of Reducing Lead Time in Development－

Abstract

An evaluation method that yielded a quantitative index of usability was demonstrated in the previous paper, but if the discovery that the level of usability is low is made at a stage when the design work has been finished, it is difficult at that point to implement a fundamental solution. This led to the idea that if usability could be evaluated in the planning stage, that is, in the first stage of
