Should You Outsource Advertising and Marketing Production?

Because I work for an outsourcing company, I know first-hand that outsourcing continues to be a popular management tool in 2010 with no signs of slowing down in the near future.  Companies are dealing with the global recession and working to focus on their core competencies.  I see on a daily basis that, in both the private and public sector, organizations are increasingly turning over various internal functions to outside providers in order to reduce costs, improve efficiency and increase flexibility.
