The roles of user participation (UP) in the design of Management Accou
nting Information System(s) (MAS) have long received the attention of
MAS researchers. By surveying business firms through a structured ques
tionnaire, this study investigated the interactions among contextual v
ariables (Task uncertainty and organizational structure), information
characteristics (Scope, timeliness and aggregation) and UP. The result
s suggest that under high task uncertainty, aggregated and timely info
rmation with high UP is positively associated with increased MAS perfo
rmance. However, when the task uncertainty is low, the UP makes no imp
act on the relation between performance and information characteristic
s. In a less structured organization, broad scope, timely and aggregat
ed information with high UP has a positive influence on the performanc
e. In mechanistic organization, narrow scope and disaggregated informa
tion through the high UP can lead to higher MAS performance. (C) 1998
