MANAGING IT IN A DIGITAL WORLD
• IT has become more pervasive
- IT is not used only by back-office workers, but also front-line workers
- More and more employees are reliant upon IT for accomplishing their work
activities
• Business managers, not just IT managers, are responsible for IT
investments and effective system utilization
• By the Year 2000, the total annual cost of IT purchases was more
than half of the annual capital expenditures of businesses in
developed countries

which can help “level” the economic playing field

RECENT INFORMATION TECHNOLOGY TRENDS
• Computer Software: Integrated, Downloadable, Social
• Integrated
- Standardization has enabled more integration
- Many “standards” are just de facto standards (Microsoft
Windows, Office, Internet Explorer)
- Many companies have benefitted from “Enterprise Systems”
investments (e.g., electronic health records in hospitals)
Enterprise Systems:
Software packages with integrated modules that pass
common business transactions across groups,
divisions, and geographic locations in “real time”
