How do you maintain an organization's IT technical documentation and ensure it is up-to-date?

"One of the more critical aspects of my job as a systems engineer at Cisco is to maintain the organization's IT-related documentation. I do this both online and manually using several different methodologies. Whenever the company acquires a new IT asset, I ensure that the related documentation is archived in an online file system and printed technical manuals, if applicable. The online records are carefully indexed and cross-referenced, so support personnel can quickly find the information they need about a particular system to resolve an issue. I also maintain a separate database of Cisco's software licenses with renewal dates and user information. This allows me to keep the software up to date and make sure the organization has the correct number of licenses needed for each system or application. My team and I perform quarterly reviews of the documentation to ensure that everything is up to date."
