19. New Part Summary
Part quoted with a 12 week lead time and delivered in less than
11 weeks.
“It has been a pleasure working with SMT throughout the entire procuring process.
From the beginning you and your team were very responsive and very easy to work
with. The parts you dropped off Monday look great, and our quality engineer who
performed First Article Inspection commented on the quality of the part and your
facility. It is not every day that a vendor provides a quality product and delivers a full
week ahead of schedule. I am looking forward to working with SMT in the future and I
just wanted to thank you for all your hard work.”
Many things, including, complexity, number and types of outside
processes, and revision changes, influence the lead time and
responsiveness.
20. Letter from Goodrich buyer, 12/2010
“As I walked through the facility it was obvious there is a high level of value placed on the employees of
SMT. The facility was very clean, organized, with machines strategically located, all good indicators of a
committed and dedicated work team. There was also evidence of a strong emphasis on lean manufacturing
practices which supports effective cost reduction opportunities.
Also obvious was the commitment to stay current with the latest machining capabilities. The machines are
modern, appeared to be well maintained and strategically located to support the lean concept and most
important, an AS9001 quality system. The installation of the water jet deburr machine is a significant
addition to the overall operation.
In today’s supply chain environment where reduction and consolidation are the norm, first impressions are
more important then ever and SMT shows well. As a participant of the Goodrich Corporation Interiors
machining team I will include your company as a potential machining supplier to all Interiors sites of
Goodrich, domestic and internationally.
My applause to SMT’s President, Roy Sweatman for successfully leading his company through these rough
economic times and for preparing SMT for continued growth and success.”
