What is Business Analytics?
Analytics is the use of: data, information technology, statistical analysis, quantitative methods, and mathematical or computer-based models to help managers gain improved insight about their business operations and make better, fact-based decisions.
Business analytics is “a process of transforming data into actions through analysis and insights in the context of organizational decision making and problem solving.”

Modern business analytics can be viewed as an integration of BI/IS, statistics, and modelling and optimization as illustrated in Figure.
Listed below are some of the important aspects of Business Analytics as shown in the figure
Data Mining is focused on better understanding characteristics and patterns among variables in large databases using a variety of statistical and analytical tools. Many standard statistical tools as well as more advanced ones are used extensively in data mining.
Simulation and Risk Analysis relies on spreadsheet models and statistical analysis to examine the impacts of uncertainty in the estimates and their potential interaction with one another on the output variable of interest. Spreadsheets and formal models allow one to manipulate data to perform what-if analysis—how specific combinations of inputs that reflect key assumptions will affect model outputs.
What-If Analysis is also used to assess the sensitivity of optimization models to changes in data inputs and provide better insight for making good decisions.
Visualization- Visualizing data and results of analyses provide
a way of easily communicating data at all levels of a business and can reveal surprising patterns and relationships.

Prescriptive analytics

1
|
Definition
|
The use of data to understand past and current business
performance and make informed decisions.
|
Predictive analytics seeks to predict the future by
examining
Historical data, detecting patterns or relationships in
these data, and then extrapolating these relationships forward in time.
|
Prescriptive analytics factors information about possible
situations or scenarios, available resources, past performance, and current
performance, and suggests a course of action or strategy.
|
2
|
Hierarchy
|
Descriptive Analytics is the first part of any model building
exercise. We analyze the historical data to identify patterns and trends of
the dependent and independent variables.
|
Predictive Analytics is the next stage of analytics. Here, we
leverage the cleaned and/or transformed data and fit a model on that data to
predict the future behavior of the dependent variable.
|
Prescriptive Analytics is the last stage where the predictions are
used to prescribe (or recommend) the next set of things to be done.
|

|
Process
|
Categorize,
characterize, consolidate, and classify data to convert it into useful
information for the purposes of understanding and analyzing business
performance.
|
Using advanced techniques, predictive analytics can help
to detect hidden patterns in large quantities of data to segment and group data
into coherent sets to predict behaviour and detect trends.
|
Prescriptive analytics relies
on artificial intelligence techniques, such as machine learning, to
understand and advance from the data it acquires, adapting all the while.
|
4
|
Output
|
This process
allows managers to obtain standard and customized reports and then drill down
into the data and make queries to understand the impact of an advertising
campaign, for example, review business performance to find problems or areas
of opportunity, and identify patterns and trends in data.
|
This process allows a bank manager to identify the most profitable
customers Or predict the chances that a loan applicant will default, or alert
a credit-card customer to a potential fraudulent charge.
|
Prescriptive analytics is used in many areas of business, including operations, marketing,
and finance. For example, we may determine the best pricing and advertising strategy to maximize revenue, the optimal
amount of cash to store in ATMs.
|
5
|
Application
|
Typical
questions that descriptive analytics helps answer are “How much did we sell
in each region?” “What was our revenue and profit last quarter?”
|
Predictive analytics helps to answer questions such as
“What will happen if demand falls by 10% or if supplier prices
go up 5%?” “What do we expect to pay for fuel over the next several months?” “What
is the risk of losing money in a new business venture?”
|
Prescriptive analytics addresses questions such
as “How much should we produce to maximize profit?” “What
is the best way of shipping goods from our factories to minimize costs?”
“Should we change
our plans if a natural disaster closes a supplier’s
factory: if so, by how much?”
|

|
Practical Usage
|
Descriptive analytics can help to identify the areas of strength and
weakness in an organization.
|
Predictive analytics look at patterns in data to determine if
those patterns are likely to emerge again, which allows businesses and
investors to adjust where they use their resources to take advantage of
possible future events.
|
Prescriptive analytics can simulate the probability of various outcomes
and show the probability of each, helping organizations to better understand
the level of risk and uncertainty they face than they could be relying on
averages.
