R.E. & Contractor, N. (1990). Conceptual effects of office
systems: A methodology and application for the study of alpha, beta,
gamma change. Decision Sciences, 21(2), 301-317.
This article applies the concepts of alpha, beta, and gamma changes
to test whether the implementation of a new office information system
networking capabilities changes the way organizational members
office work. Traditional approach (t-test) was used to measure
change and indicated little change in how effectively the respondents
they performed eight generic office activities before implementation
and nine months after implementation (T2). However, considerable change
was detected between effectiveness reported at T1 and retrospective
of T1effectiveness reported at T2 (called "then" assessments). Strong
was also detected between "then" assessments and T2 effectiveness
at T2, indicating beta change. Multiple hierarchical tests showed that
most of the change was actually gamma change; the T2 and the "then"
structures and convariances differed significantly. This study supports
propositions that using computers to accomplish organizational work may
be associated with different conceptualizations of work, which may
ambiguity and uncertainty if training and management policies do not
appropriately. Finally, this study provides an expanded version of a
solution to detecting alpha, beta, and gamma changes.
