Complexity breeds Complexity

One of my teachers used to say, just like success breeds success, complexity breeds complexity.

Computers were introduced in business to handle increased size (in terms of customer reach, volume of market, globalization, voluminous production, etc) and complexity of business (different legal frameworks in different countries, understanding of business with increasing attributes, etc). But with increase in computing power and numerous business applications we have computer systems which are to support computer application and even department (IT department) and whole IT industry. Think about following applications/disciplines which exist to support computerization of business.

1. IT department
2. Identity Management
3. Master Data Management
4. Data ware house
5. Business Intelligence
6. Decision Support System
7. Collaboration Suites ( Email, messaging, Wiki, Document management system)
8. Integration Practice/Suite
9. ETL Suites
10. BPM Suite
11. Versioning System
12. Ticketing Systems
13. Software Licensing Management
14. Intrusion Detection System
15. Enterprise Search
