Alstom, global leader in the transportation sector, has participated in a tender for the supply of trains for all the Italian regions. Their offer consisted in a customization of the train cars according to the needs of each area. We designed a multilayer tender kit capable of explaining this concept through paper based and digital tools; a tablet with the video intruduction, the booklets, a USB with the digital configurator and a CD with all the documents in digital format. The experience in the fruition of this kit was remarkable and Alstom won the tender.
