• Develop leaders' ability to coach problem solving, reinforce standards, identify abnormalities, and build continuous improvement into daily operations.
• Build problem-solving capability within the organization so that teams can resolve issues without continued dependence on an outside facilitator.
• Support the definition of meaningful operational KPIs and build the management routines needed to review performance, respond to abnormalities, and maintain accountability.
• Partner with Finance and business leaders to establish baselines, validate improvement benefits, and monitor whether intended results are sustained.
• Use data and direct observation to identify recurring problems, distinguish symptoms from root causes, and prioritize improvement work based on customer and business impact.
• Support change adoption by identifying stakeholder needs, anticipating resistance, and helping leaders communicate and reinforce new expectations.
• Develop reusable continuous improvement standards, methods, coaching materials, and learning experiences that strengthen ProtoExcellence capability across the site.
• Communicate progress, risks, decisions, and results clearly to site and functional leadership. Perform other related duties as assigned.
