This paper is part of an effort to develop a model to measure the level of efficiency in interfacing electronic mail systems with users at the terminal. In this paper, we define the guidelines for codifying errors made during the interaction. These findings will suggest ways of developing new systems with greater efficiency and improving the performance of existing systems
