A Good Content Management System Should:

• Have an intuitive graphical user interface and should be easy to understand and use, even to a non technical user.
• Allow custom designing of the frontend so that the website can have an unique look and feel.
• Be highly extensible by allowing plug-ins and modules to build upon or add to core features.
• Not need a programmer to set up and run.
• Be secure and compatible with best practices and open standards.
• Have extensive documentation and community support.
• Pick a great CMS to start with and design, development and deployment of your website will be considerably easier.
