Hi Barton, although vague (it all depends on what you consider as medium sized CMS implementation) here it goes my answer.
Having stated and froze requirements, I would risk to say that that it would take between 2-5 months to have the system running with no problems (I mean working as predicted and required by users, including training). But because frozen requirements never exist I would risk 3-6 months. Complex CMS's implementations take around 1-1.5 year (in stages to 3-4 months). Easy usually implementations take 0.5-2 months. Then again this all depends what you believe it's an easy, medium or complex CMS implementation, and what is a completed CMS implementation. This are not estimates for your implementation (I have no knowledge about your requirements, technology, analysis, nothing to do such estimate). They are just some pointers. Best regards, Nuno Lopes Independent Consultant -- http://cms-list.org/ trim your replies for good karma.
