Management and Human Factors
Standards and Tolerances. Lack of suitable standards and tolerances,
or lack of their enforcement, can make a mockery of any attempt to accomplish
meaningful alignment. More specific recommendations will be
given later.
Training. Inadequately trained alignment personnel are likely to do poor
alignment, quickly, or good alignment, slowly. Well trained and equipped
personnel, by contrast, can do good alignment systematically and efficiently
without wasting time in a trial-and-error approach.
Time Skimping. In training people to do alignment systematically and
efficiently, the most frequent comment from students goes something like
this:
I like the new tools and methods you have shown us. I would like to
use them to do a better job. But, when I am given an alignment job
to do, my supervisor wants a fast job, and quality is secondary. So,
