Maybe the physical area would
have to be enlarged too much to make this recommendation effective.

an effective recommendation.
It probably goes hand-in-hand with the
training suggestion.
We hope you can see from the example just presented that the decisions
made in the acquisition process are not cast in concrete and are made over
and over again during the developmental process and life cycle of any piece
of equipment.
So now you've completed all but two of the lessons in your human
factors course.
Congratulations!
Before beginning the next lesson, read
Pages 174-176 of HEL TM 29-76.
Your next lesson will continue using
TM 24-76. See you in Lesson 39. Turn to Page 29.
