How do you establish good communication and information flow with others?

A good communication and information flow is established by first identifying those " others" whom we need to communicate with: then the type information you need to convey/others need, level of details needed, means of communication, timing and frequency of communicating, preciseness of the  information conveyed. 

I believe that we must have more and more educations in communications art and science ,

Know what communication really is. Communication is the process of transferring signals/messages between a sender and a receiver through various methods (written words, nonverbal cues, spoken words). It is also the mechanism we use to establish and modify relationships. 

for example: A very good way to establish good communication and information flow with others is by working with people (i.e colleagues, customers, and potential customers) the way they want to be worked with; by prior professional understanding about the best way to work with them, that encourages trust and "comfort".

By making those you want to communicate with understand what you are saying, by talking with them with simply languages that they can simply understand easily.

1. identify what needs to be communicated.
2. Have courage to say what i think.
3. Enunciate my words.
4. Use the right words
5. Slow my speech down.
6. Use appropriate volume
7. Do not interrupt or talk over the other person--it breaks the flow of conversation. Timing is important.
8. Make eye contact when speaking and listening

Actually Information flows in two ways:

1. Upward flow

2. Downward Flow

these flows are most likely to be used in a hierarchy of an organization for reporting channel.

The Downward information flows from upper level management to middle level management and low level management/field operations.

Unlike Downward communication, Upward communication flows from field level management to Supervisors, Middle Level Management and upper level management to make informed decisions.
