A model proposed by Schultz, Ginzberg & Lucas (1984) that integrates the
factor and process approaches to implementation was field tested with data
from a generalized decision support system. Significant associations were
found between manager acceptance and user perceptions of support, user
personal stake and system use. The results suggest that voluntary and
non-voluntary use of a system have different precursors and may be encouraged
in different ways. Although the overall model receives only partial support,
the results of the study suggest approaches for further testing of network
models of implementation.Information Systems Working Papers Serie
