Noupe.com has a few suggestions for you when you go to pick out your next content management system with ten guidelines that can help:

The content management system you choose can really make a huge difference in how much time you (or your clients) spend keeping a site updated and maintained. There's a huge variety out there-some estimates put the number at around 1700 different options. Some are great...some, not so much.

Among the suggestions are things like:

• A CMS needs to work intuitively.
• The backend needs to be logical and well-organized.
• The right CMS shouldn't have a ton of extra functionality you'll never use.
• The right CMS should be easy for non-geeks to use.
• The pages it creates should be fast-loading and have simple code.

They also mention a few options available that might be a good fit for you and your organization: WordPress, SilverStripe, Joomla! and a few more.
