Inevitably in such situations, there is enormous potential for conflict between the need for precise
application of a procedure and a more practical approach. Technical considerations may favour very close
control within the specified procedure but practical limitations may preclude strict observance of the
requirements. To insist on close control may prejudice the immediate operation of the plant by prolonging
the repair work, and a critical review of requirements may be necessary. Obviously, malpractice cannot be
condoned under any circumstances, but there are instances when technical guidance or practical experience
is all that is necessary to assure quality and the punitive imposition of standards can have a completely
adverse effect.
