What you have done should be informed to others

All of a sudden,I deeply relized that timely communication is fairly important,so as to reduce unnecessay waste,such as time or energy.
Therefore, the ability of anticipate is very important,you should think of it prior to others.

In a word,
1-Effective communication,what you have done and what you will do should be informed to others.
2-A of the A.R.G,A is equal to anticipate,thinking of it prior to others.
