as shown in many contributions that highlight the failure of the manufacturing resource planning production control system to effectively manage an engineer-to-order system .
Uncertainty, dynamics and complexity of engineer-to-order systems make inapplicable the information systems based on the features of the more standardized manufacturing
systems, like make to stock .
From previous considerations it emerges that in the engineer-to-order companies the quotation phase is the most pivotal one.
We believe that the implementation of the integrated Information Technology solution in this crucial phase can bring significant advantages, especially in reducing
