Bruce Cletheroe

Kevin is Chair of the IMechE’s Engineering for Reliability Work Group and Network Rail’s Subject Matter Exert in Design For Reliability. He is an IMechE Fellow who gained his passion for continuous improvement at Ford Motor Company, where he was Quality Supervisor for Dagenham Body and Assembly Plant. His MSc in Advanced Automotive Engineering gained him a patent for an intelligent system which identified squeak and rattle issues using frequency finger-printing in 1996.

As part of Ford’s world class Engineering Quality Improvement Programme, he trained and supported engineers and managers in Total Quality Management tools such as Statistical Process Control, Design of Experiments, Potential Failure Mode and Effects Analysis, Problem Solving, Quality Function Deployment and Robustness. This allowed him to build an extensive portfolio of successful projects, including winning Ford’s prestigious President’s Customer Driven Quality Award twice. Kevin was on the first waves of Ford’s Six Sigma Black Belt and Master Black Belt training and then headed up and deployed Six Sigma into foundries, V-Engine plants, Automatic Transmission Design and Diesel Engineering.

After spending time as the Quality and Reliability Supervisor for European Diesel Engines fitted into Jaguar vehicles, Kevin joined Network Rail to deliver their Maintenance Six Sigma Programme leading to very significant signed-off savings. A role as Reliability Improvement Manager for Signalling, led him to identify the need, write and gain stakeholder approval for Network Rail’s mandated Design for Reliability Standard, integrating reliability tools into the design process. He has briefed and taught this to Network Rail, suppliers and European Infrastructure Management companies. Kevin received a Network Rail Technical Fellowships, for experience and knowledge in the fields of quality and reliability. He won Kepner Tregoe’s combined technologies 2022 Global Excellence Award for his work on Design For Reliability and recognised at the 2022 National Rail Awards for his Outstanding Personal Contribution to Rail. Kevin has written a regular article on reliability for ‘Rail Infrastructure Magazine’ since July 2022.
