When Germany’s largest grocery retailer reevaluates its entire order-picking technology, it’s about more than just optimization — it’s about long-term strategic viability. EDEKA recognized early on that its existing pick-by-voice system could no longer meet the growing demands for efficiency, ergonomics, and cost-effectiveness. The requirements for a new system were clear: it needed to be more powerful, more flexible, and more economically attractive — all while integrating seamlessly into existing operations. Following a brief but intensive testing phase, the decision was clear: EPG (Ehrhardt Partner Group) won out across the board with LYDIA Voice. The solution not only met all technical and economic criteria, but also enabled a smooth, phased transition by allowing parallel operation with the legacy system. This approach allowed approximately 10,000 users across 33 locations to become familiar with the new technology without any loss in productivity. The rollout was carried out gradually across regional distribution centers.
