Business intelligence

From Wikipedia, the free encyclopedia

The term business intelligence (BI) refers to technologies, applications and practices for the collection, integration, analysis, and presentation of business information and also sometimes to the information itself. The purpose of business intelligence is to support better business decision making. It dates to 1958.[1] D. J. Power explains in "A Brief History of Decision Support Systems,"[2]

BI describes a set of concepts and methods to improve business decision making by using fact-based support systems. BI is sometimes used interchangeably with briefing books, report and query tools and executive information systems. Business Intelligence systems are data-driven DSS.

BI systems provide historical, current, and predictive views of business operations, most often using data that has been gathered into a data warehouse or a data mart and occasionally working from operational data. Software elements support the use of this information by assisting in the extraction, analysis, and reporting of information. Applications tackle sales, production, financial, and many other sources of business data for purposes that include, notably, business performance management. Information may be gathered on comparable companies to produce benchmarks.

[edit] History

Prior to the start of the Information Age in the late 20th century, businesses had to collect data from non-automated sources. Businesses then lacked the computing resources necessary to properly analyze the data, and as a result, companies often made business decisions primarily on the basis of intuition.

As businesses automated systems the amount of data increased but its collection remained difficult due to the inability of information to be moved between or within systems. Analysis of information informed for long-term decision making, but was slow and often required the use of instinct or expertise to make short-term decisions. Business intelligence was defined in an October 1958 IBM Journal article by Hans Peter Luhn.[1] Luhn wrote,

In this paper, business is a collection of activities carried on for whatever purpose, be it science, technology, commerce, industry, law, government, defense, et cetera. The communication facility serving the conduct of a business (in the broad sense) may be referred to as an intelligence system. The notion of intelligence is also defined here, in a more general sense, as "the ability to apprehend the interrelationships of presented facts in such a way as to guide action towards a desired goal."

In modern businesses the use of standards, automation and specialized software allows large volumes of information to be warehoused, extracted, transformed and loaded to greatly increase the speed at which data becomes available, including the use of online tools.

In 1989 Howard Dresner, later a Gartner Group analyst, popularized BI as an umbrella term to describe a set of concepts and methods to improve business decision-making by using fact-based decision support systems.[3]

[edit] Key intelligence topics

Business intelligence often uses key performance indicators (KPIs) to assess the present state of business and to prescribe a course of action. Examples of KPIs are things such as lead conversion rate (in sales) and inventory turnover (in inventory management). Prior to the widespread adoption of computer and web applications, when information had to be manually input and calculated, performance data was often not available for weeks or months. Recently, banks have tried to make data available at shorter intervals and have reduced delays. The KPI methodology was further expanded with the Chief Performance Officer methodology which incorporated KPIs and root cause analysis into a single methodology.

Businesses that face higher operational/credit risk loading, such as credit card companies and "wealth management" services, often make KPI-related data available weekly. In some cases, companies may even offer a daily analysis of data. This fast pace requires analysts to use IT systems to process this large volume of data.
