There is a delicate dance between outsourcing vendors and the secure management of their knowledge resources at play. The challenge for the vendor stems from their need to earn their clients trust by engendering high levels of confidence in their abilities to effectively deliver goods and services sought by the client without compromising the security of their knowledge resources. The potential for the outsourcing vendor project teams to interact with a diverse set of clients adds and even greater level of complexity.
