This case study details the implementation of Kern 1600 and Kern 3600 inserting machines at Dienst Uitvoering Onderwijs (DUO) in Groningen, Netherlands. The decision to invest in these systems was made after a comprehensive Europe-wide tender process, emphasizing the importance of due diligence in selecting the right equipment. The installation occurred in two stages to ensure operational continuity, addressing initial teething problems effectively. The Kern systems are noted for their high processing speeds and efficiency, capable of handling various envelope formats. The case study also highlights the collaboration between DUO and Kern, including a visit to Kern's factory for testing prior to installation, which contributed to a successful acceptance process. The focus on reliable service and ongoing support from Kern is emphasized as a critical factor in the partnership. Overall, the case study illustrates the successful integration of advanced logistics solutions in the educational sector.
