factors that enhance or impede information flow in each step of the process
I don't know what process you are discussing.
In terms of information theory, noise can interfere with information flow. Noise is anything in the environment between the sender and the receiver that interferes with the message. It can include random sounds in the environment, static on a radio, "snow" on a TV screen/monitor, a penned letter that has gotten wet to smear the ink, or even wind if you are using smoke signals.
The clarity of the message itself (words, phrases, abbreviations, etc.) for both sender and receiver can enhance or impede the information flow. (Your not being clear about what process is involved impedes the flow.)
I hope this helps a little more.
