Despite the increasing role of the data warehouse as a strategic information source for decision
makers, academic research has been lacking, especially from an organizational perspective. An
exploratory study was conducted to improve general understanding of data warehousing issues from
the perspective of IS success. For this, the effect of variables pertaining to system quality,
information quality, and service quality on user satisfaction for the data warehouse was studied.
Additional characterization was made on data warehouse users, their organizational tasks, and data
warehouse usage. Empirical data were gathered at a large enterprise from three different information
sources: a survey, unstructured group interviews with end-users, and informal interviews with an IT
manager who was in charge of the data warehouse. Data analysis showed that user satisfaction with
the data warehouse was significantly affected by such system quality factors as data quality, data
locatability, and system throughput. Interviews also supported the existence of system design and
management issues that have to be addressed to optimize the utility of the data warehouse as an
effective decision support environment. In the meantime, data analysis indicated that first-line (or
lower) and middle managers were the main users of the system. Managers and knowledge workers
were taking advantage of the system to perform complex tasks, to support decision making, and to
seek information critical for enhanced productivity. The group interviews revealed additional benefits
of the data warehouse and major roadblocks in its successful usage.
