Information needs in business
• To run a business,
useful,timely,accurate,reliable,and valid
data are needed.
• When data in the raw form are evaluated,
analyzed, and synthesized,useful
information becomes available to
managers for making good business
decisions.
Information needs in business
• Almost every organization has to engage
in research at some level to stay
competitive.
• Companies gather data both from within
and outside the organization.
• The methods used to gather,analyze,and
synthesize information from the external
and internal environments are becoming
increasingly sophisticated to the immense
scope of computer technology.

needs?
• The difference between data and information.

•
The information for marketing research tends to come from three main sources:
•
Internal Company Information – e.g. sales, orders, customer profiles, stocks,
customer service reports
Marketing intelligence –include all the everyday information about developments in
the market that helps a business prepare and adjust its marketing plans. It can be
obtained from many sources, including suppliers, customers and distributors.
Market Research – existing data from internal sources may not provide sufficient
detail. Similarly, published reports from market intelligence organisations cannot
always be relied upon to provide the up-to-date, relevant information required.

Q: A travel agent has recently introduced a computer system into their
High Street branches. Describe two reasons why they might have
introduced this system. (4 marks)
• The answer
• The computers can be connected to the Internet (or they
may use leased lines) to access industry databases to
find the best deal for the customer. The company can
also use the computers to send emails to all its
branches. Email arrives quickly and so is much quicker
than the postal service.
• The question is worth 4 marks, and so a full explanation
is needed. Each reason is worth 2 points, and needs to
cover why the system was introduced, and how the
company benefits from it.

Marketing research
• Marketing research can be concerned with any of a
variety of aspects of the market: the product, sales, buyer
behaviour, promotion, distribution, pricing, packaging,
etc.
• Since the researcher cannot investigate everything about
a market, he/she must be selective. The question
remains as to how the researcher decides where to
focus the study, and to what depth each issue should be
investigated.
• The research design is a set of guidelines given to the
researcher by the person(s) who have commissioned the
research and/or the individual(s) who are to make use of
the results in their decision making.

•
The correlation is one of the most common and most useful statistics. A
correlation is a single number that describes the degree of relationship
between two variables.
