When it comes to business writing, shorter is better.

Everyone is familiar with the well-thought-out memo, which contains virtually all the details about its subject. Too long to read now, you print it for later. It sits in the stack, with that magazine article that you're saving for when you have the proper amount of time to devote to it. Then, other important items get added to the stack, and that critical memo keeps falling lower, ultimately becoming neglected as it fades in importance over time.

As everyone in business knows, finding the time to read anything lengthy can be challenging, at best. In a nationwide survey of senior executives and managers that we at NFI Research conducted, 85 percent of those in large companies said the written communications they receive from their subordinates are too long. Almost half said they were significantly so.

"Being clear and concise is probably the most important key to effective business writing," said one survey respondent. "I've seen brilliant ideas from brilliant coworkers go unnoticed for no other reason than they were buried in way too much text."

Said another: "Many e-mails are short but with long attachments. E-mails saying, 'Please read this' with a long attachment and no descriptive subject are real time-wasters."

As another executive pointed out, unless there is a very complex situation to be described, most problems or solutions can be explained in a few lines.

Writing Quality Is Bad, Too

The length of written business communications is not the only issue. A lack of quality also irks many survey respondents.

"I notice a marked decline in the structure, grammar, syntax and overall impact of messages in written communications," said one manager. "This applies both to subordinates and, to a lesser degree, to the C-level communicator."

"Unfortunately, we take the written communication too lightly today," said another respondent. "Text messages, IM and brief e-mails have diminished our ability to share our thoughts, plans, recommendations and goals effectively. This lack of professionalism ultimately slips into other areas, lessening our effectiveness as a company."

Some managers we surveyed think college students simply have forgotten—or never learned—how to write. "College students just have poorly developed writing skills," one respondent said, and poor writing makes them look unprofessional. "Over the years, I have seen an increase in bad grammar," said another. "Guess kids aren't learning English like they used to."
