Anyone who has built a complex website with a modern content management system (CMS), and one without, knows what wonderful marvels CMS's are. A good CMS provides a development team with thousands of developer hours (that’s my PC way of not saying man hours) of code that has been tested and burned-in on a multitude of websites. The prevailing wisdom is that a good CMS greatly reduces the cost and time to deliver a website, particularly for advanced sites.
