A study examined how organizational members describe their use and perceptions of electronic mail systems. Fifty-five subjects with access to electronic mail systems were interviewed at two organizations. Results indicated that subjects used the electronic mail system in the following ways: 84% for memos, notes, and correspondence; 53% for voice mailing; 37% for updating calendars and setting up meetings; 30% for obtaining or communicating necessary information; 22% to obtain technical information; 15% for brainstorming and problem solving; and 2% for document preparation. In general, results suggest that automated office systems have little or no impact on healthy interpersonal relationships and in some cases the system extends social interaction with other organizational members. However, the data also suggest that when interpersonal relationships or organizational climate are faltering, technology may contribute to the continued deterioration of the situation. Electronic mail systems clearly change the way that employees communicate, process information, and develop and maintain relationships. (The interview guide used to collect data is appended.) (SRT)
