Maturity level modeling has been a well-established and important stream of IS research. Maturity models have played a significant role in guiding organizational process improvements in many areas. It is therefore surprising that maturity model design and development methodologies have not yet been scrutinized from cross-cultural and international perspectives. In this research, we have prescribed a rigorous approach to identifying, validating and calibrating maturity models constructs for cross-cultural application. We have employed this new methodology in the context of widely accepted business intelligence maturity model that has been initially developed in Germany. Our current effort involves following our proposed methodology to target and calibrate those nationally specific model components that need modification and calibration for application in the US. We report on our progress, and we discuss implications in terms of both findings relevant to culture in IS research, maturity model methodology research and BI maturity model research.
