Kathleen, welcome to your new position. There are lots of questions that new folks have, and this is one of the first. Once you have filled out the CDS, you can keep it handy because many of the survey companies will allow you to send the CDS to them rather than you having to fill out a survey form. An example is College Board's BigFuture. While their survey won't open until January, they have indicated you can send them your completed CDS as soon as you have it ready.
In addition, many schools will post the CDS on their website.
Other than that, you can use it for questions you receive, e.g., how many students or faculty your institution has.
