day no. 15,006: many advisers, one decision

"Relations among all leaders—from corporal to general—should be based on honesty and frankness regardless of disparity between grades. Until a commander has reached and stated a decision, subordinates should consider it their duty to provide honest, professional
opinions even though these may be in disagreement with the senior’s opinions. However, once the decision has been reached, juniors then must support it as if it were their own. Seniors must encourage candor among subordinates and must not hide behind their grade insignia. Ready compliance for the purpose of personal advancement—the behavior of 'yes-men' will not be tolerated."

Proverbs 20:18
Plans are established by counsel;
by wise guidance wage war.

Generals may be above their subordinates in rank, but the must not be above hearing their opinions. Good ideas do not, by necessity, originate with those of rank. 

Proverbs 11:14
For lack of guidance, a nation falls, 
but with many counselors comes deliverance.

It is wise to get as much information and guidance as you can when making decisions that affect the lives and deaths of many.

Proverbs 15:22
Plans fail for lack of counsel,
but with many advisers they succeed.

No man can foresee every angle or pay proper attention to every detail. We all have abilities and interests, but we naturally see the value of mining the depths of some dimensions while ignoring entirely the benefits of others.

Proverbs 24:5-6
A wise man is full of strength,
and a man of knowledge enhances his might,
for by wise guidance you can wage your war,
and in abundance of counselors there is victory.

But still, there comes a time for a decision to be made, and at that point, the General must make a definitive decision based on the information and counsel provided. To be the General means to be humble enough to hear ideas and confident enough to choose one.

Leaders must be humble enough to hear ideas, yet proud enough to pick one

Trumpkin and Caspian understood this. Trumpkin was a man under authority invited to share his opinion. He shared it. Caspian heard it and decided a different course. Trumpkin did not share insisting that his counsel had to be followed in order to qualify as it having been heard. Caspian was Trumpkin's superior. Caspian was responsible for the nation and made the decision he believed best after hearing Trumpkin's counsel and Trumpkin, in response, fell in line immediately under his head.

"But I thought you didn't believe in the Horn, Trumpkin," said Caspian. 

"No more I do, your Majesty. But what does that got to do with it? I might as well die on a wild goose chase as die here. You are my King. I know the difference between giving advice and giving orders. You have my advice and now it's the time for orders"
