The channel, or medium, used to communicate a message affects how accurately the message will be received. Verbal, written, and nonverbal communications have different strengths and weaknesses. In business, the decision to communicate verbally or in written form can be a powerful one. In addition, a smart manager is aware of the nonverbal messages conveyed by either type of communication—as noted earlier, only 7% of verbal communication comes from the words themselves.

Business Use of E-Mail

The growth of e-mail has been spectacular, but it has also created challenges in managing information and an ever-increasing speed of doing business. Over 100 million adults in the United States use e-mail regularly (at least once a day). Internet users around the world send an estimated 60 billion e-mails every day, and many of those are spam or scam attempts. That makes e-mail the second most popular medium of communication worldwide, second only to voice. A 2005 study estimated that less than 1% of all written human communications even reached paper—and we can imagine that this percentage has gone down even further since then To combat the overuse of e-mail, companies such as Intel have even instituted “no e-mail Fridays” where all communication is done via other communication channels.

An important, although often ignored, rule when communicating emotional information is that e-mail’s lack of richness can be your loss. As we saw in the chart above, e-mail is a medium-rich channel. It can convey facts quickly. But when it comes to emotion, e-mail’s flaws make it far less desirable a choice than oral communication—the 55% of nonverbal cues that make a conversation comprehensible to a listener are missing. E-mail readers don’t pick up on sarcasm and other tonal aspects of writing as much as the writer believes they will, researchers note in a recent study.

The Sender may believe she has included these emotional signifiers in her Message. But, with words alone, those signifiers are not there. This gap between the form and content of e-mail inspired the rise of emoticons—symbols that offer clues to the emotional side of the words in each Message. Generally speaking, however, emoticons are not considered professional in business communication.

You might feel uncomfortable conveying an emotionally laden message verbally, especially when the message contains unwanted news. Sending an e-mail to your staff that there will be no bonuses this year may seem easier than breaking the bad news face-to-face, but that doesn’t mean that e-mail is an effective or appropriate way to deliver this kind of news. When the Message is emotional, the Sender should use verbal communication. Indeed, a good rule of thumb is that the more emotionally laden messages require more thought in the choice of channel and how they are communicated.

Direction of Communication Within Organizations

Information can move horizontally, from a Sender to a Receiver, as we’ve seen. It can also move vertically, down from top management or up from the front line. Information can also move diagonally between and among levels of an organization, such as a Message from a customer service representative up to a manager in the manufacturing department, or a Message from the chief financial officer sent down to all department heads.

There is a chance for these arrows to go awry, of course. As Mihaly Csikszentmihalyi, author of best-selling books such as Flow, has noted, “In large organizations the dilution of information as it passes up and down the hierarchy, and horizontally across departments, can undermine the effort to focus on common goals.” Managers need to keep this in mind when they make organization design decisions as part of the organizing function.

The organizational status of the Sender can affect the Receiver’s attentiveness to the Message. For example, consider: A senior manager sends a memo to a production supervisor. The supervisor, who has a lower status within the organization, is likely to pay close attention to the Message. The same information, conveyed in the opposite direction, however, might not get the attention it deserves. The Message would be filtered by the senior manager’s perception of priorities and urgencies.

Requests are just one kind of communication in business. Other communications, both verbal or written, may seek, give, or exchange information. Research shows that frequent communications with one’s supervisor is related to better job performance ratings and overall organizational performance. Research also shows that lateral communication done between peers can influence important organizational outcomes such as turnover.

External Communications

External communications deliver specific business messages to individuals outside an organization. They may announce changes in staff or strategy, earnings, and more. The goal of an external communication is to create a specific Message that the Receiver will understand and share with others. Examples of external communications include the following:
