A novel maturity model for the information-driven decision-making process (DMP) in organisations is presented. The 'circumplex hierarchical representation of organisation maturity assessment' (CHROMA) model was developed for evaluating organisations regarding their competence and readiness in using information to support decisions. This model groups the most important informed decision factors into five dimensions data availability, data quality, data analysis and insights, information use and decision-making. The model addresses these dimensions in an organised and systematic way, providing a framework for characterising the organisation's use of information in DMPs from an uninitiated stage to a completely embedded one. This model was tested in a pilot study on three small/medium-sized enterprises. The assessment involves interviewing key company personnel and evaluating the attributes and dimensions of the CHROMA model. Results indicate that the model is useful for identifying strengths and weaknesses, thereby providing insights for prioritising improvement actions.
