Statistical Quality Control

• Statistical Process Control (SPC)– A concurrent process control method that uses

statistical tests of probability in determining if product quality is within the acceptable range.

Statistical Quality Control Steps

1. Set the desired quality standard and range.1. Set the desired quality standard and range.

2. Determine the frequency of measuring performance and the sampling technique.

The Information Systems Process

6

Types of Information Systems• Transaction Processing Systems (TPS)– Used to handle routine and recurring business

matters (e.g. accounting transactions).

• Management Information Systems (MIS) – Used to transform data into information that

managers need from the database to do their work.

• Decision Support Systems (DSS)– Use a manager’s insights in an interactive computer-

based process to assist in making non-routine decisions.

7

Types of Information Systems (cont’d)

• Artificial Intelligence (AI)– An attempt to create computers that simulate the

human decision process.

• Expert Systems– Imitate the thought processes of a human being.

Information Networks and Technology• Computer Networks– Connect independent computers so that they can function in

interrelated ways.

• Information Networks– Connect all employees from headquarters and remote facilities

to each other, to suppliers and customers, and into databases.

• Types of Networks– Local-area networks (LAN)– Wide-area networks (WAN)– Firewalls, intranets, and peer-to-peer
