Design/methodology/approach: This investigation is based on a survey data collection from a sample of 192 Portuguese companies. A neural network model has been developed to identify the effects of each dimension of MO on each dimension of performance. Findings: Relationship among MO and performance was corroborated but MO's impact is poor and based on its first dimension, market intelligence generation. Research limitations/implications: Further research in this field should be conducted using other tools offered by neural network modelling. Practical implications: Managers should give more attention to cross-functional co-ordination in order to improve market intelligence dissemination and responsiveness and, thus, global performance. Originality/value: The paper presents the development of a neural network model to analyse this relationship.engMarket orientationMarketing intelligenceBusiness performanceModellingNeural netsPortugaljournal article10.1108/03090560910935505
