Guava Tree puzzles -
I must admit that I have been surprised about how Boeing can hire assembly workers with such minimum knowledge and intellect but still train them enough (need to know) to get the job done.But history has proved that, for Boeing, this works.
The difference is that in the Boeing shop, an assembler need only address a few tasks and thus he can master them fairly quickly. A maintenance shop needs versatile folks who can work competently on radomes and trim tabs and all in between.
