ABSTRACT
Formal written reports also have some liabilities: 1. Because of their potentially widespread and long-term
2. Because the potential audience may be diverse, it may be difficult to satisfy completely the needs of all readers. Given their virtues and liabilities, formal written reports
of the previous informal report. Thus, the informal report may sometimes dispense with establishing the context, presenting background material, and so on. It must, however, refresh the reader's memory, if necessary. Therefore, the longer the reporting interval, the more likely it is that some review of the project's previous status or current plan will be needed.
