SAP and other enterprise resource planning packages are rapidly penetrating many corporate environments. These packages are already dominant in several industries, e.g., petrochemicals, semiconductors, personal computers, and consumer products, and they are entering several other industries such as financial services, health care, and the public sector. These “mega- packages” have the potential of helping organizations achieve higher levels of cross-functional and cross-geography integration than ever before. They also present technological, project management, and organizational change challenges that have never been faced by most organizations.
