Before ACTING,
weigh up the potential benefit
versus potential harm

If the HARM outweighs the BENEFIT, find another way forward

It's not enough to do your best,
you must KNOW WHAT TO DO
and then do your best

GOOD DESIGN
can compensate for poor workpersonship
BUT
good workpersonship can't compensate for POOR DESIGN

The ESSENCE OF LEADERSHIP is holding
your people to the HIGHEST POSSIBLE STANDARD 
while taking the BEST POSSIBLE CARE of them
