In today's technologically advanced and constantly changing economy, many organizations are changing the way they do business. The traditional model is often proving ineffective, and many organizations that resist change are losing profits and missing opportunities for expansion. Another factor that contributes to this new economy is globalization; “global markets now produce and consume about 20 percent of the world's output,” an amount that is expected to increase to more than 80 percent by 2007 [1]. New technologies and common standards are making global business interactions less costly and easier to conduct. In addition, the increased pace of business and technological innovations are “pushing people to become more dynamic both within and between organizations” [1].
