Stories are inherently sequential. One thing happens, then another, then another. That structure works well not only in books and films, but also in business writing because it helps readers follow along. When giving a factual account, use chronology to keep your writing clear, efficient, and interesting. To help you relay the narrative in order — rather than jumping in at the middle or even the end — create a “chronology of relevant events” before you write. List all of the important dates and events then use it to guide your writing, making sure you still write in a way that’s personal.
