As a client, you can insist on remedial action. Insist on name recognition. Don't go halfway. Don't settle for half-hearted measures or intermediaries who manage only some aspects of your business when the more efficient solution is to outsource the entire process. For example, if the telemarketing employees of a credit collection company only make calls on your behalf but do not follow up with any necessary customer visits, the collection function may be incomplete.
Accountability is everything.
Beware of regulations. Make sure your outsourcing partner understands and complies with all the rules and regulations governing your industry and the workplace. Insist on peace of mind. Your outsourcing partner should control its own infrastructure and have built-in safeguards, for instance, when it comes to protecting your information and your employees' privacy.
