Communication can help an organization achieve its goals in at least two major ways.
First, it can help the organization achieve its external goals. Organizations typically want to accomplish things that depend on people outside the organization. A non-governmental organization might want to reduce the rate of AIDS while a business wants to make profit. Communication can help to persuade others to take actions (engaging in less risky behaviors, buying the business’s products) that help to achieve these goals.
Second it can help the organization achieve its internal goals. Organizations typically want to run more efficiently. Communication between the different levels of the organization can be a major help in bringing this efficiency about.
