Historical Context
The concept of business intelligence (BI) and the role of Business Intelligence Analysts have evolved significantly over time. The term “business intelligence” was first coined by Richard Millar Devens in 1865 in the Cyclopaedia of Commercial and Business Anecdotes to describe how Sir Henry Furnese gained profit by receiving and acting on information about his environment before his competitors. However, the modern BI analyst’s role emerged in the late 20th century with the advent of sophisticated data collection and processing technologies.
Key Events in the Evolution of Business Intelligence
- 1958: Hans Peter Luhn, an IBM researcher, publishes “A Business Intelligence System,” outlining the potential of BI.
- 1970s-1980s: Development of Decision Support Systems (DSS), leading to early BI tools.
- 1990s: BI tools become more user-friendly, with a focus on end-users rather than IT specialists.
- 2000s: Integration of BI with big data, advanced analytics, and the rise of self-service BI tools.
- Present Day: BI analysts leverage AI and machine learning to deliver insights.
Types/Categories of Business Intelligence
- Descriptive Analytics: Analysis of historical data to understand past trends.
- Diagnostic Analytics: Examination of data to determine why past events happened.
- Predictive Analytics: Use of statistical models and forecasts to predict future outcomes.
- Prescriptive Analytics: Analysis to recommend actions to achieve desired outcomes.
