Relationship of Systems to One Another

• TPS Major source of data for other systems
• ESS Primarily a recipient of data from
  lower-level systems
• Other systems may exchange data as well
• Exchange of data between functional areas
• E.g. Sales order transmitted to manufacturing
  system
• In most organizations, systems are loosely
  integrated

Interrelationships Among Systems
Figure 2-13
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.
