1. Without reading any of this week’s assigned readings, briefly describe your understanding of “information systems.” Now read the Nolan and Wetherbe (1980) article. Describe your new understanding of information systems. How is it similar or different to your prior understanding of information systems?
2. In the case study you read about the positive impact of IS (TradeNet) on TBD’s organizational structure, business process, business network, business scope, and performance. Do you think TradeNet could have had any negative impacts as well on employees, organizational culture, etc.? If it did have any negative impact on TBD, what are they and how could they be managed?

Using a business or organization you are familiar with, contrast the operational, managerial, and executive levels by comparing each level’s typical activities, use of IS, types of decisions made with the IS, and information needs.
