Why does reporting fall apart when deadlines hit?

You tell yourself the problem is the pressure. It is not. Pressure only finds what was already weak. If your process lives in your head, pressure will break it every time, because memory fails first when you need it most. Look honestly at what you actually do. You remember most of the steps, most of the time. Then a deadline moves, someone asks a question mid-task, and a step gets skipped. That is not bad luck. That is the predictable result of never writing the process down. You cannot control when the pressure comes. You can control whether your process depends on your memory or not. That choice is yours to make today, before the next deadline, not during it.
