Two people send the same true information about the same problem to the same organisation. One gets a fix by Thursday. The other gets no reply. The difference is almost never honesty or effort — it is that one of them decided who was reading and what the message was supposed to achieve, and the other just wrote down what happened.
Audience: Three Questions, Not One
“Who is my audience” is usually answered with a role — my teacher, my manager, the customer. That is not enough to change a single sentence. Three questions do the actual work.
- What do they already know? Everything you explain that they already knew costs you attention you needed later. Everything you assume that they did not know costs you the whole message.
- What will they have to do? If the answer is “nothing”, this is an update and should be short. If the answer is “decide something”, the decision goes at the top, not at the end of the story.
- What are they worried about? A teacher reading about a missed deadline is worried about fairness to everyone else. A manager is worried about who else is affected. Neither worry is in your version of the story unless you put it there.
Purpose: Say the Job Out Loud
Before writing, finish this sentence: “After reading this, they will ___.” If you cannot finish it, the message is not ready, and no amount of polish will fix that.
The most common defect is two purposes in one message. An update with a hidden request buried in the last line reads as an update, gets filed as an update, and the request never happens. If you need something, the need is the message — put it where a reader who stops after two lines still sees it.
The Same Facts, Three Readers
Take one situation: your part of a group project is late because the person with the data stopped replying.
Short, direct, no formality, one specific ask with a time on it. Anything longer reads as building a case against them.
Slightly formal, states the situation without blaming a named person, and — critically — includes what you have already tried. A teacher’s worry is fairness, so the message that works is the one that shows you did your part.
Shortest of the three. The impact and the proposed fix in the first two lines, detail underneath for anyone who wants it. A manager’s worry is what else this affects.
Nothing in those three versions contradicts the others. Every one of them is true. They are different because the readers are different and the jobs are different.
The Two Failures Look Nothing Alike
Getting the audience wrong and getting the purpose wrong produce different symptoms, which is useful — you can diagnose which one you did from the reply you got.
- Wrong audience. The reply asks you to explain something you thought was obvious, or asks a question you already answered. The reader did not have the context you assumed, or had more than you gave them credit for.
- Wrong purpose. There is no reply. Or the reply agrees warmly with you and does nothing, because nothing in the message told them an action was expected.
The second is the more expensive one and the harder one to notice, because a friendly non-answer does not feel like a failure. It is, though — the message did not do its job, and the clock kept running.
Length Is a Decision, Not a Byproduct
Most people treat length as whatever falls out of writing everything they know. It is worth treating as a choice, because it carries meaning of its own: a long message to a busy reader says “I have not worked out what matters here”, and a two-line message about a serious problem says “I do not think this is serious”.
A working rule: the less time a reader has, and the less they already know about you, the shorter the message and the earlier the ask. Seniority and unfamiliarity both push in the same direction, and both push harder than most people expect.
The exception is anything that will be kept as a record — an application, a complaint, an account of what happened. Those get read slowly by someone deciding something, and there the missing detail costs more than the extra paragraph.
Checking Yourself
A cheap habit: after writing, read only the first two lines and ask whether a reader who stopped there would know what you want. Most people find, uncomfortably often, that they would not.
The Communication Adaptability test scores audience and purpose as its own subscale across six of its 24 situations, alongside three other skills — so a weak result here is separable from, say, knowing what an email is supposed to look like.
