What Is Business Intelligence?
1. Business intelligence (BI) is the delivery of accurate, useful in-
formation to the appropriate decision makers within the necessary time
frame to support effective decision making.
By this definition all the
work we have done with Excel would qualify as business intelligence
since our deliverables contained accurate and useful information to
support effective decision making. However, business intelligence is
commonly under stood to include distilling
and analyzing large data
sets such as those found in corporate databases. Extracting and analyz-
ing information stored in databases is the subject BI. It is very likely
that at multiple points in your work career you will be asked to engage
in just this type of analysis.
2. Business intelligence is part of the big picture information sys-
tems architecture. Most systems in existence can be classified either as
enterprise systems, collaboration systems, or business intelligence sys-
tems. The enterprise systems—taking orders for example—feed their
data to the data warehouse, which in turn is queried to support business
intelligence.
3. From a managerial standpoint, there are three factors necessary
to make an effective decision:
- Construct a set of goals to work toward.
- Determine a way to measure whether a chosen path is moving
closer or farther from those goals.
- Present information on those measures
to decision makers in a
timely fashion
4. For example, let’s say our goals are to develop a clothing busi-
ness that produces high quality products while lowering costs. We fur-
ther determine that we will measure product quality by the percentage
of products rejected by inspectors at each station. (Think about those
quality inspector tags that you find in pockets of your new clothes. The
clothes you are wearing are the ones accepted by the inspector.) A rela-
tively high rejection rate is a red flag to management requiring further
54
analysis. Is this an overzealous inspector? Is there any pattern to the
rejected products? Does one station in the factory tend to produce more
rejects than the others?
5. We also need to see performance over time. Is product quality
improving or getting progressively worse?
Let’s say that our analysis determines that the high rejection rate
comes from just one factory in Southeast
Asia. We report the problem to management. They dispatch a team
to review the plant. The
review discovers child labor, abusive condi-
tions, and very low morale at the plant. The horrible conditions are
quickly re- versed and the rejection rate returns to average.
6. We will look at three types of business intelligence—static re-
ports, dynamic reports, and data mining. Static
reports are by far the
most common form of business intelligence. Most businesses have
summarized standard reports already laid out and printed to assist in
managerial decision making. For example, universities use enrollment
reports to gauge which departments might need to hire more faculty.
Credit card companies will request reports of persons with high credit
scores to target credit card promotions. Similarly, the companies might
target college students with good future earning potential. Marketers
might look at sales figures for different stores and regions to determine
where there are opportunities to run a sales promotion.
7. Dynamic reports look similar to static reports but online and in-
teractive. A manager curious as to where a certain summary number on
his dashboard comes from can drill down to expose the detail that con-
tributed to that number. In essence it is a fact-finding tour where infor-
mation discovered in each step gives clues on where to search next for
information. For example, if sales
in North America are down, then
drill down to discover a problem in the Midwest region. Then drill
down farther to discover a problem in the Cleveland, Ohio plant.
8. Data mining uses computer programs and statistical analyses to
search for unexpected patterns, correlations, trends, and clustering in
the data. In essence, it is fishing through the data to see if there are pat-
55
terns of interest. One often cited example
of data mining was the dis-
covery that beer and diapers are frequently purchased on the same trip
to the grocery store. Upon further inquiry marketers discovered that
Dad picks up some beer on his trip to the grocery store to buy diapers.
Marketers can use this information to place the two items in close prox-
imity in the store.
