Historical
Success
Past
Since TWI the mission from the start in June 1940 was “to
help industry to help itself to get out more materials than have
ever been thought possible, and at constantly accelerating speed” to
win a global war”, the fact that the Allied countries did
in fact win a global war indicates TWI was successful in accomplishing
its mission. The reason we know that is because the TWI founders
had the foresight to monitor 600 of their client companies throughout
the war to gather data to evaluate their performance. The following
data from these 600 companies leaves no doubt that TWI contributed
to winning the war of production even after having to start from
scratch way behind the production capacity of the warring nations
that had also stockpiled the materials of war knowing in advance
they would be put to use.
| 86% |
increased production by at least 25% |
| 100% |
reduced training time by 25% or more |
| 88% |
reduced labor-hours by over 25% |
| 55% |
reduced scrap by at least 25% |
| 100% |
reduced grievances by more than 25% |
When evaluating statistics, the question arises
as to just what do these numbers really mean the actual contribution
these companies contributed to the final outcome of the war. Since
the greater majority of those companies monitored by the TWI Service
were those who produced war materiel, let’s take a look at
the role TWI had at Boeing to determine how these statistics translate
into a more precise measure of the contribution TWI training actually
made for Boeing to help “win a global war.” See story
below.
Building the B17 at Boeing
Boeing had to rush the production of the 17 bomber in 1940 at
a time when they didn’t even have a production facility.
On top of that, the company had to manufacture the largest and
most sophisticated bomber at the time with a workforce of 33,000
people one half of whom were made up of cowboys, wheat farmers,
salmon fishermen, and lumberjacks. The other half were, for the
most part, made up of Seattle-area housewives
With women workers doing direct work for the first time, Boeing
engineers designed and constantly revised tools and processes
to maximize worker productivity by minimizing strain and fatigue.
System development was guided by a few principles:
- Keep tools and materials in line workers’ hands
- Keep both direct processes and support systems very simple
to avoid confusion, and
- Engineer the airplane for fast, efficient production
This in turn changed the roles of the supervisor who now had
to solve problems fast in the workplace to keep production lines
moving. With the pace of production and frequency of engineering
changes, supervisors had to be on the shop floor checking and
coaching constantly. Because they also had to show people how
to do the work, supervisor training and knowledge of standard
work instructions was doubly important.
Training Within Industry (TWI) was used to train supervisors
on how to break down common industrial tasks into easily digested,
easily mastered steps to train new people and also to cross-train
employees to promote teamwork and for people to learn how to
take on a broader responsibility within their work area. What
effect did the combination of TWI and Lean have on the on the
production of the B-17?
- 60% reduction in man hours per airplane.
- Fly-a way’s went from the initial quote of 75/mo. in
1941 to a peak of 364, one every 1.6 hours in March 1944.
- Initial cost of $242,000 per plane in 1940 was reduced to
a final cost of $139,254 in March 1944, 42.46% in 32 months
A quick look at Shipbuilding
- Consolidated
Steel Corp., Orange, Texas – 1945
- 18,749 employees
- Every
supervisor was certified in one or more of the “J” programs
- The company attributed the following results to TWI over a
four year period:
| Increase in production |
45% |
| Reduction in tool breakage |
75% |
| Reduction in training time |
78% |
| Saving in manpower |
45% |
| Reduction in scrap |
69% |
| Reduction in accidents |
69% |
In the 2 years following the Battle of Midway
at which both the US and the Japanese lost all but 2 carriers.
After that battle was fought,
- The Japanese shipbuilders
launched 6 carriers.
- During the same period, US shipbuilders
launched:
- 17 carriers, plus
- 10 medium carriers,
and
- 86 escort carriers
"Such numbers, to be repeated
in myriad categories of war materiel, spelled doom for Japan."

Present
Toyota has been using TWI Training since 1951 and
the company has projected to pass GM in sales in 2007 or 2008.
ESCO Turbine Technologies- Syracuse credits the TWI Job Instruction
Program for reducing rework by 96% in a two year period and to
maintain that high level of quality since.
