You have an website that has grown over time, and while it is very useful, much of the content is out of date or inaccurate, it’s hard to find things, updating the site is complex, the appearance may be dated and you’ve lost track of the pages on the site.
How a CMS overcomes these issues:
Content Management Systems (CMS) systems are designed to simplify the publication content to websites, by allowing users without any technical knowledge or HTML skills to create content, keeping the website fresh and current. The processes involved in managing the website are separated by the CMS, CMS sites need not be expensive and users have full control.
