I need your "HELP" answering this questions:

1. Explain how web enabled technology has made outsourcing a viable option for all companies, regardless of size?

2. Give specifics of how having real time access to world class skills sets on a global scale has impacted the reengineering of corporate value chain?

3. Discuss how this trend has blurred the B2B and B2E E-business models?
