International Truck Recognizes High-Performing Dealers for Their Commitment to Improving Service Dwell Time

March 13th, 2017 – Summit Truck Group today announced that 12 of its dealership locations have been recognized by International Truck as a Diamond Edge℠ certified dealer. The following Summit Truck Group locations received this recognition: Oklahoma City, OK, Wichita, KS, Kansas City, MO, Joplin, MO, Kansas City, KS, Tye, TX, San Angelo, TX, Farmington, NM, Salina, KS, North Little Rock, AR, Russellville, AR, and Lowell, AR. The Diamond Edge program is a collaborative effort between International Truck and its dealer body to recognize dealers for their commitment to uptime and to drive awareness of the high-performing service offered to customers from dealers with this designation.

                “International Truck has an unrelenting passion for delivering on our mission of uptime,” said Victor Doran, vice president, Customer & Dealer Support, Navistar. “Diamond Edge certification recognizes dealers with the highest-performing service departments in our network.”

                Diamond Edge Certification is earned by achieving rigorous parts and service metrics based on customer dwell time, which is the time it takes for a customer to get their truck diagnosed, repaired and back on the road.

 To achieve Diamond Edge certification status, International truck dealers must:

  • Meet or exceed service dwell time and repair velocity metrics
  • Develop long-term action plans for continuous service dwell time and customer service improvement
  • Be current with technician and service management training requirements
  • Maintain special service tools inventory for specific repairs as required
  • Provide dedicated Accelerated Service lanes where customers receive immediate vehicle evaluation and are informed of required repair, required parts and availability, and estimated repair time within two hours of vehicle’s arrival
  • Participate in the Dealership Inventory Alliance (DIA) parts inventory program to ensure common parts are readily available in dealer inventory
