Every sentence earns its place. It either explains something, instructs someone, or connects one idea to the next. If it does none of these, it becomes a bit of clutter.
Most filler hides in plain sight. A soft qualifier here. A vague comment there. A sentence that repeats what the last one already said. These small details quietly weaken the reading experience.
Why It Matters for Product Teams
A purpose driven edit sharpens writing fast. When every line carries weight, the whole piece reads with more intention.
It forces clarity of thought. If you cannot say what a sentence is doing, it probably should not be there.
It also builds trust. Readers move through the page without hitting fluff or friction.
How to Apply It
Make every sentence serve a purpose. It either instructs, informs, or connects one idea to another. If it does not do one of those jobs, cut it or rewrite it until it does.
