Abstract:

Choosing a content management system (CMS) is not just about finding the product with the right functionality. It's also about dealing with a vendor who can support your needs for the lifetime of the solution. This briefing explores the way most CMS vendors have evolved, what this means for the way they work, and what you should be looking for when purchasing a solution.
