Misfit between Manufacturing Resource Planning (MRPII) system and the manufacturing environment of adopting organization are well known in contributing to the failure of the system implementation and jeopardizing the system performance. Hence, it is vital to have a better understanding of the system-context misfit problem. Nevertheless, limited studies have empirically examined the relationship between the misfit and the system outcome, especially at the dimensional level of the variables. The purpose of this paper is to introduce a Misfit-Inviability Model (MIM) to conceptualize of relationships between MRPII misfit, extent of organizational readiness, and MRPII system outcome, at the dimensional level of each variable and grounded on strong theoretical foundations. The MIM is an enhancement of existing Fit-Viability Model (FVM). In terms of implication, the new model manages to represent the system adoption as a dynamic process over time, by incorporating implementation contingencies. Additionally, the framework serves as a general model that can be adapted to assess the relationship between outcome of various information systems and the misfits. Future research may include more testing and validation of the dimensions and constructs used in the model.
