Measuring innovation best practices: Improvement of an innovation index integrating threshold and synergy effects

Innovation, as a competitive economic factor, is a process that requires a continuous, evolving and mastered management. Therefore innovative companies need to measure their innovation capacity. Literature attests of research in the field of innovation measurement or the innovation abilities evaluation. One major theoretical problem consists in elaborating mathematical models that consider the threshold effect and synergy between innovation practices and verify their validity. In this article, mathematical approaches supplementing multi-criteria models are suggested.
