In order to develop a view of the basis for systems analysis practice,
this paper examines the relations among problem situations, decision
makers, and systems analysis activities. Its central thesis is that th
ese relations constitute a form of dialogue that is essential for effe
ctive systems analysis work. Although the context of the discussion is
restricted to the one in which systems analysis has been classically
effective (problem situations that are relatively easy to structure, i
n which some important aspect is dominated by technology, and where th
ere are identifiable decision makers), the basis established here can
be extended to broader contexts.
