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

SHERMAN, TEXAS – JANUARY 16, 2018 – Graham International today announced that it has been recognized by International Truck as a Diamond Edge℠ Certified dealer, 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.
“It is an honor for our dealership and people at Graham International to have earned the Diamond Edge certification,” said Brett Graham, CEO. “It validates our commitment to reduce dwell time and improve service for our customers who rely on their trucks every day to maintain and grow their businesses.”
“International Truck has an unrelenting passion for delivering on our mission of uptime,” said Victor Doran, vice president, Customer Support, Navistar. “The Diamond Edge Certified Program 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 metrics and define long-term action plans for continuous and ongoing service dwell time improvement at dealership location
• Provide dedicated Accelerated Service where customers receive immediate vehicle evaluation by a technician and are informed of required repair, required parts and availability, and estimated repair time within two hours of vehicle’s arrival
• Top Service Departments must commit to adopting technology like our Accelerator Write-up App™, a first-of-its-kind mobile app created to expedite service visits by streamlining the write-up and diagnostic process
• Participate in the dealership inventory alliance (DIA) parts inventory program to ensure common parts are readily available in dealer inventory
“We are proud to be a Diamond Edge certified International truck dealer serving North Texas and Southern Oklahoma because we know that our service is keeping our customers’ trucks on the road,” added Graham.
