This paper describes a series of interviews that focus on the ways that professional office workers use electronic mail to manage their daily work. A number of implications for the design of flexible mail systems are discussed. Two principal claims are made. First, electronic mail is more than just a communication system. In addition to supporting information management, it provides a mechanism for supporting a variety of time management and task management activities.
Some people are prioritizers , concentrating on the problem of managing incoming messages.
Others are archivers , concentrating on how to archive information for subsequent use. Similarly, some people use mail to delegate tasks, while others perform tasks delegated to them by others electronically. The second claim is that use of electronic mail is strikingly diverse, although not infinitely so. Individuals vary in their preferences, both in their general willingness to manage their work electronically and in their specific preferences along the dimensions described above. This diversity implies that one's own experiences with electronic mail are unlikely to provide sufficient understanding of other's uses of mail.
