Audit: How effective is your CRM system?
SearchCRM.com
If I was auditing your system I would ask the same questions you should ask and they would be along the lines of what your business needs are, how they are or are not being met today, and what metrics you will use to evaluate the situation. This is a good practice and remember to apply it both to the old system you want to take out and the new system you want to replace it with. Does the new system meet all of your requirements? If not, keep looking.
