To be successful, an
organization must constantly
monitor and respond to—or
even anticipate—developments
in its environment. A firm's
environment includes specific
groups with which the business
must deal directly, such as
customers, suppliers, and
competitors as well as the
broader general environment,
including socioeconomic trends,
political conditions,
technological innovations, and
global events.

The various types of systems in the
organization have interdependencies. TPS are
major producers of information that is required
by many other systems in the firm, which, in
turn, produce information for other systems.
These different types of systems have been
loosely coupled in most organizations.
