Task 3 This reminder(提示)is intended to offer guidance for using e-mail. This is not a“ how-to" document, but it is rather a document that offers advice to prevent you from being cheated or troubled by e-mails. Studies show that knowledge workers spend about 20 hours a week doing e-mail and one-third of that e-mail is useless. Still worse,70%of this e-mail gets handled within six minutes of arrival and the average worker is interrupted every three minutes As a consequence, there is a cost to our organizations. While we can't control what we receive from the outside, we can make some progress from the inside. Please read this paper and take action by following its instructions. Many thanks go to Earl Hacker(CIO,WBB Consulting, Inc.)for providing some of this information from an internet site.
