It’s 4:30 on Friday afternoon when you get the message that a key vendor will not be able to deliver what they promised on time, which will in turn cause YOU to miss a critical deadline for your most important client. Frustrated, you call the vendor, who instantly denies ever being told about the deadline. You know deadlines were discussed but can’t find it in your original written agreement. You then turn to your e-mail only to be forced to dig through hundreds of messages to try and find the e-mail where you conveyed the importance of this project being delivered on time, but you can’t find it because it was deleted.
