A contextual approach for designing and using Operational Research OR quantitative models

Practitioners of Operations Research (OR) traditionally concentrate on mathematical and computational aspects of quantitative models, sometimes resulting in risky implementation or early model obsolescence. This paper proposes an approach, inspired by system concepts and technology management, which includes softer influences, such as decision frequency, model life cycle and technological stage of management, to help modeling and model management decisions. Some graphic indicators are developed to help diagnosis and conception.
