Whip out emails and memos, but set aside the appropriate amount of time to write important projects. Shut the door, stick a strip of police tape across the opening of your cubicle, turn off the phone, clear your desk, take a deep breath… then take the time to 1) think and plan your project, and 2) write it. The project will go easier, faster and what you write will be more intelligent and professional than if you rush through it.
