The second method of projecting deadlines is working from beginning date of the project to the ending. In many companies, you, as the project manager, get to calculate your own deadline dates. Or, in an effort to share the joy, you can ask your writers to plan out their own schedules, and you can act as the implementor of the schedules. It takes two days to edit them, and you need two edits to be performed. Writing the second draft takes three days.
Printing again takes five days to turn around the project.
