Computer Operations, (3) Engineering Project Work, And (4) Plant Management.
1.1 4 What Is The USA Principle? What Does Each Of The Letters Stand For?
ANS: The USA Principle Is A Common Sense Approach To Automation And Process Improvement Projects. U
Means “Understand The Existing Process,” S Stands For “Simplify The Process,” And A Stands For “Automated
The Process.”
1.1 5 The Text Lists Ten Strategies For Automation And Process Improvement. Identify Five Of These Strategies.
ANS: The Ten Strategies Listed In The Text Are (1) Specialization Of Operations, (2) Combined Operations, (3)
Simultaneous Operations, (4) Integration Of Operations, (5) Increased Flexibility, (6) Improved Material Handling
