Learning Objectives
 Understand the difference between the levels
of individual, work group, and organization.
 Define and discuss individual-level systems.
 Define and discuss work group–level systems.
 Define and discuss organizational-level
systems.
 Define and discuss inter-organizational-level
systems.
Why study HCI?
 To help make IS users more productive,
 To help IS professionals develop more
usable and successful systems,
 To enhance organizational effectiveness,
 To provide researchers with cohesive and
cumulative knowledge for theory building,
and,
 To apply this theoretical knowledge to
enhance real information systems.

Organization of this chapter
 This chapter sets the stage for the study of human–




computer interaction (HCI) in organizations.
The levels of interaction (task, syntax, semantics, and
lexical) help to organize the different sections of this
chapter.
Tasks are categorized as structured, semi-structured,
or unstructured.
We introduce the various levels of systems which are
individual, work group, organizational, and interorganizational.
HCI as a means for overcoming human limitations.

Inter-organizational Systems
 Inter-organizational systems are those
systems that link companies with external
organizations (not individual customers).
Usually this link is a B2B (business-tobusiness) link between suppliers and
business customers.

Summary
 This chapter is structured around four levels
of information systems: the individual, the
work group, the entire organization, and the
inter-organizational level.
 At each level, various systems that support
the level are presented along with the four
levels of HCI (task, semantic, syntactic, and
lexical).
