Senior Vice President
Operations, North America
Keith Sieverding has an unusual challenge within the Simpler® organization. Among his other responsibilities, Keith is charged with continuous improvement inside the company, following the Simpler Business System model. In other words, his job is to make sure we walk the Lean walk—he is Simpler's "sensei to the sensei."
Keith also oversees new, product-focused developmental services and is responsible for knowledge management within the Simpler organization. He is a strategic leader, exhibiting remarkable insight as a seasoned Lean veteran.
Before joining us in 1999, Keith spent 20 years with Hill-Rom, a global producer of medical equipment for the patient room environment. It was at Hill-Rom, under the coaching of the Shingijutsu Group, that he developed his repertoire of Lean tools. He has implemented Lean concepts in a variety of applications, from manufacturing to administration, engineering and customer service, throughout Hill-Rom acquisitions in Germany, France and Austria.
His career assignments have included diverse positions relating to aspects of design, development and manufacturing. He has overseen the delivery of varied goods, from custom-designed make-to-order field-erected steel and concrete structures, to high volume/high mix short lead time consumer products.
Steve Matteson's Lean journey started with a visit to Japan in 1989, and it continues to grow every year. Steve has more than 25 years of experience across different industrial sectors, including healthcare, manufacturing, defense and banking. He’s worked in an equally impressive array of capacities: Production Manager, Plant Manager, Division Manufacturing Manager, General Manager, Director, VP and Executive VP.
Trained as an engineer and holding an MBA, Steve measures success by results. By his own measure, he's racked up successful Lean results for a number of clients. In healthcare, he changed a hospital's operating room charge capture process to avoid missing revenue potentials and increased revenue by $ 1.14 million. And he reduced patient flow time in a clinic from 46 to 22 minutes; the clinic is now expanding business and revenue totals on existing assets.
On the commercial side, Steve turned around a privately held company, rebuilding 96% of the client portfolio and raising profitability 2.5 times. He increased profitability for a division of another privately held company by 400%, reducing labor costs, increasing on-time delivery and generating nearly $70 million in new business without adding building assets. At a Fortune 500 company plant site with nearly 1,000 employees and significant labor strife, he turned a bottom line loss into a nearly 3% ROS profit. Sales increased by near $40 million, without adding space.
As a key player on the Simpler® Healthcare team, Steve is helping us bring these kinds of results to a host of healthcare organizations.
Tim Whitmore brings 28 years of operations leadership experience to every Lean Transformation engagement he takes on. He began his Lean journey as a plant manager for HON Industries, a Fortune 500 company, learning the Lean approach under the coaching of the Shingijutsu Group, the original architects of the Toyota Production System.
Tim's success with the application of Lean tools has led to a series of promotions, first within HON and then with other companies. Some of that success can be measured in numbers. As Executive Vice President and Chief Operating Officer at SITONIT Inc., a startup manufacturer of ergonomic office seating, for instance, Tim achieved sales revenue growth of 118% and an increase in operating profit of 138% over a 20-month period.
But Lean Transformation is about more than sales and profits. Tim has also driven significant improvements in product quality, delivery performance and employee satisfaction.
Tim joined Simpler® Consulting in June 2001 as a Senior Consultant. He was promoted to Manager of Consulting Services in September 2001, and then to Vice President Consulting Services in December 2003. And he continues to grow within the company and be an important part of Simpler's success.
