Many documents have a content problem: too much, too little, or the wrong things entirely.
Without deliberate thought about what to include — and what to cut — it's easy to ramble, bury the important stuff, or leave out something your reader actually needed. The result is a document that feels complete to you but doesn't work for them.
Good content selection isn't just about knowing your subject. It's about balancing two different agendas: what you want to say, and what your reader needs to hear. Those aren't always the same thing — and learning to tell the difference, and judging what matters most, is one of the most useful skills a workplace writer can develop.
