assumption challenging. They argue that no
single technique is capable of capturing full
the diversity of the work setting.
Dearden and Wright draw an interesting
distinction between techniques that are situat-
ed in the work context and those that go
beyond the immediate situation. The former
techniques can be used only in the work place.
The latter allow the analyst and the user to
detect issues beyond the range of the observ-
able situation, for example, the organizational
and historical contexts. Dearden and Wright
assert that different techniques have different
strengths and weaknesses. Observation allows
one to separate what people say they do from
what they really do, but it has practical limita-
tions. With only a limited amount of time in
the workplace it may be impossible to see the
full process. Infrequent, but nonetheless
important, problems may not crop up while
you are actually there. Only by using a variety
of situated and nonsituated techniques can
the fullest account emerge, given the prevail-
ing practical constraints. The rich picture can
serve as a representation to motivate all these
different sources of information about the
work. It can also serve as a representation to
integrate information regarding the higher
level work context coming from
