听力原文： I want to thank you, the team managers, for taking this time out of your busy schedules to be informed of the updates on our computer system. Since we've seen an increase in sales of 19% from year to year, we also needed to increase data on the sales of each item. Therefore, a few new servers have been bought, and the networking capabilities have been updated. You will notice a gray booklet on your desk once you arrive at your workstation from lunch. Please follow its instructions to install three new programs. The first program will help with the tracking of inventory. The second program will assist you in the management of your client listings. And the third program will manage your internal communications. We have streamlined the three communication channels into one. Now it will only be necessary to check this one channel whenever you are checking for and sending internal messages. Who is most likely the audience of this talk?
