Websites also provide product descriptions (+ Search inside the book) to
better inform shoppers. Will this become a competitive advantage for the
store?

2. Problem Solving
Information Systems can be used for problem solving
A Laptop Problem (page 30)
Problem: a perceived difference between what is and what ought to be.
Problem definition: defines the difference by describing both the current
situation and the desired situation,
e.g. the customer support representative do not have data about the
prior call to best assist a customer
Solution:
1. A CRM System to store customer information and all the
interactions (Chapter 7)
2. Knowledge Management System to provide customer procedures
to fix the laptops (Chapter 9)
3. A Manufacturing Quality-Control Information System to eliminate
possible faulty laptops

Other problems
MIS in use 2-1 (page 32)
Some other examples:Company directory updates.
Company A has personnel transfer between department frequently.
Jessie is the personnel in charge of publishing company phone books. Every 6 months, she send out a form to all the employees to see if they need to update their contact information. She then organize the changes into a new file and order new prints which will be available for distribution in 2 weeks
Problem: – Costly publishing

Information System can facilitate decision making
Decision Levels
Operational: day-to-day activities
How many widgets should we order? e.g. Transaction
processing systems (TPS)
Managerial: allocation and utilization of resources.
How much should we budget for computer hardware and
software for department A? e.g. Management Information
Systems (MIS)
Strategic: broader-scope, organizational issues.
Should we acquire company A? or allied with company B? e.g.
Executive information systems (EIS)

Decision Process

Well understood and accepted methods for decision making
For example: Formula available to calculate when and how
many units of material to order.
Many formulae can be learnt from HTM 406.

For example, predicting of the future economy and effect of
strategic alliance.
