 John
Allen specializes in the application of engineering
principles within the context of product performance,
product durability, and reliability improvement in manufacturing
companies. John's clients have included General Motors,
Pratt & Whitney, General Electric, Rolls Royce,
US Steel, Delphi, Philips Consumer Electronics, Siemens
Electronics and others. He has worked in foundries and
chemical companies, and on precision machining, plastic
molding, precision assembly and extrusion and blown
film. John has worked on planes, trains, and automobiles
around the world.
John's reputation is based upon his ability to efficiently
assist clients in solving complex technical problems.
There are three projects that solidified his reputation.
The first involved defects in cast aluminum heads. Scrap
was in excess of 50%, much of it not found until after
machining or installation in the vehicle, causing assembly
line stops and warranty problems. John's small team
reduced the scrap to less than 1%, eliminated warranty
claims for the defect, and virtually eliminated machining
scrap. The project required only several days of John's
time over the course of a few weeks.
Another important project was at a smelter, which suffered
from broken furnace electrodes for more than 50 years.
The life of the electrodes was unpredictable, requiring
frequent furnace outages. Over the course of one year
(it took 6 - 8 months to manufacture and consume an
electrode) the life of the best electrodes was extended
by 40%, broken electrodes were eliminated, and this
type of furnace became one of the most productive in
the world. The additional cost to produce these efficient
electrodes was about $3 for an electrode that cost in
excess of $5,000.
One more impressive project was for air seals in aircraft
engines. The first team that worked on the problem over
the course of two years, reduced scrap from 40% to 20%
and stated that no further progress could be expected.
John and his small team took over. At the end of the
project, scrap was less than 1% for these delicate components.
John has a reputation for completing complex product
performance and reliability projects quickly.
John Allen is a respected speaker and lecturer. For
years, he taught Shainin Statistical Engineering seminars,
was an annual presenter at the Shainin Symposium, and
was a keynote speaker at the Daimler Chrysler 2003 Black
Belt Symposium. John spoke at a conference of West Coast
Universities, delivering a speech, "Emulation and
Invention: Strategy, Structure and Tactics." He
was recognized in January 2002 by Shainin LLC as the
first Shainin Fellow for his contributions as Director
of Technology, for his ability to teach clients, for
solving technical problems and for training consultants.
