Some studies have reported encouraging results of IS, while others have reported nil or detrimental results. The contradictory results of these research studies can be partially a ttributed to the weaknesses in survey instruments. In an attempt to increase the validity of conclusions of IS assessment studies, survey instrument design should follow a rigorous and scientific procedure. This paper illustrates key validity and reliability issues in measuring Information Systems performance, using examples from a study designed to assess Enterprise Resource Planning systems success. The article emphasizes on the importance of the survey method and the theoretical considerations of item derivation, scale development and item evaluation. Examples are provided from the ERP assessment study to supplement the readers understanding of the theoretical concepts of survey design.

Yet for all its importance, and still consistent with observations of , system use suffers from a "too simplistic definition". Much of prior conceptualizations of use have been idiosyncratic and unsystematic. This study examines contemporary systems use and thereafter, introduces a framework for selecting system use constructs and measures based on three critical considerations: typology of the system-in-use, level of process automation, and system lifecycle. Measures are then recommended for system typologies under three types of system use: frequency, depth and explorative use. Our empirical investigation validates the framework using data from operational users of an archetype of contemporary systems-Enterprise System. Analysis of six PLS models: identify system use as an antecedent of individual-impacts, confirm the importance of depth of use, role of explorative use at early stages of a lifecycle, and alludes to issues in employing popular frequency based use measures. The study advocates several insights towards a deeper understanding of contemporary systems use. Nonetheless, future research can be directed towards a larger quantitative study to facilitate a broader theoretical and empirical treatment, and a consolidated set of prescriptive actions for practitioners.
