In a time when e-mail addresses and websites change more frequently than my daughter changes dresses, and customer needs are no more stable than the Silly Bandz fad, manufacturers are seeing a greater need to add agility to their core competencies.  Allegra Marketing Print Signs, one of the seven companies who participated in Evanston’s Manufacturing Day Walking Tour Event, demonstrated their agility to the local community during the event itself.  Students from Evanston-area high schools submitted their designs for a Manufacturing Day banner to Kyle Kurz, co-owner of Allegra, just after the event kick-off at 11:00.  By 1:30, when the tour group reached Allegra’s facility, the pre-press team at Allegra had completed the banner design, incorporating the student’s ideas and verbiage.  By 3:30 when the walking tour had wrapped up its final stop, the banner was printed and in the hands of the students for a photo op.
