Prior to being promoted to his current role, Mr. Ringel served as a Delivery Manager, responsible for quality and client satisfaction of all of MainStream's Performance Improvement consulting engagements. Mr. Ringel was responsible for aligning client expectations with MainStream's delivery of services by creating a mutual understanding of conditions critical to client satisfaction. This chartering process, now referred to as the "Conditions of Satisfaction" has been formalized within MainStream as a standard deployment model, establishing clear expectations, roles and responsibilities and the approach to the work.
In 2009 as a senior management consultant, Mr. Ringel was responsible for assessing the CPI maturity, capability and culture of the U.S. Air Force's Air Mobility Command (AMC) throughout 16 field operating units. He led the assessment effort and fielded strategies to advance the effectiveness of CPI within AMC. By the end of the planned and successfully executed five-year engagement to advance their CPI culture AMC had reported near $500 million is savings and had reached a level of maturity, which allowed them to take over full control of the performance improvement journey.
Mr. Ringel joined MainStream in 2006 as a senior management consultant. He was one of 18 Continuous Process Improvement (CPI) Masters working with the AMC in support of a Command-wide Air Force Smart Operations for the 21st Century (AFSO21) transformation across the continental United States and European and Pacific enroute systems. As the lead consultant on the engagement supporting Headquarters AMC at Scott Air Force Base he worked with the AMC and 18th Air Force Commanders in their mission providing airlift, air refueling and contingency response to U.S. Transportation Command, U.S. Central Command, and other Department of Defense agencies. Mr. Ringel facilitated the development and execution of strategy deployment at the Major Command level of the AMC, and was instrumental in integrating Lean Six Sigma, DMAIC processes, and the U.S. Air Force's 8-Step Problem Solving into a cohesive deployment methodology while providing mentorship and coaching to numerous Air Force process improvement practitioners.
Prior to joining MainStream, Mr. Ringel acquired and sharpened his practice of CPI over the course of a successful 20 year management career in the automotive supply chain serving Ford, General Motors, and Chrysler. In roles ranging from operations manager to general manager, he successfully led multiple business units in an increasingly competitive fight for market share. That experience leading business units with as many as 600 people through the necessary transformation cycles to remain competitive and successful is what gives Mr. Ringel his well rounded perspectives a performance excellence. His CPI roots reach back to his experience fielding systems that met the strict quality standards of QS 9000 and ISO 9002. He is a Master Black Belt and his Lean and Six Sigma expertise came under the tutelage of the Michigan Manufacturing Technology Center and Ford Lean Resource Center.
