What are the potential causes of issues with data


Assignment:

Data are raw facts that describe the characteristics of an event. Characteristics of a sales event could include the date, item number, item description, quantity ordered, customer name, and shipping details. Information is data converted into a meaningful and useful context.  Information from sales events could include best-selling item, worst-selling item, best customer, and worst customer.

Business intelligence is a broad, general term describing information that people use to support their decision-making efforts.  An early reference to business intelligence occurs in Sun Tzu's book titled The Art of War. Sun Tzu claims that to succeed in war; one should have full knowledge of one's strengths and weaknesses and full knowledge of the enemy's strengths and weaknesses. Lack of either one might result in defeat. A certain school of thought draws parallels between the challenges in business and those of war, specifically:

  • Collecting information.
  • Discerning patterns and meaning in the information.
  • Responding to the resultant information.

It is not data; it's competitive intelligence.  Information is competitive intelligence that drives strategic business decisions.  Decisions that are made by a global organization with the power to change the world.

Information - business intelligence - is no longer the exclusive domain of IT or research departments. From marketing and finance to management and operations, intelligence is applied strategically throughout the enterprise. Moreover, professionals who know how to gather and leverage it are the ones who will lead organizations, control decisions, and be relied upon to steer their companies.
