Nothing is more frustrating to clients when they find outdated content on your website. Many potential clients are impatient, and will simply give up, and probably seek the information from a rival companies website. What a company needs is a system where they can modify the content on their web site.
Content management systems allow ordinary members of staff in your company make updates to the content of your web site. This reduces the time it takes to publish content and greatly simplifies the process to keeping your website up to date. Workflow and versioning systems can be put into place to aid publishing in larger companies. This enables changes to content to be tracked, and enables some form of moderation to take place, so that new content can be reviewed for errors before publishing. On top of this, a permissions system can be put in place for big companies so that different departments only have access to edit specific parts of the site.
