When you’ve got a lot of variables, start by listing them and grouping by impact. Focus first on the ones that shift the outcome the most. Use data to set clear targets, then tweak one factor at a time, keeping everything else constant. Record the results, adjust, and repeat. That way you stay in control and avoid chasing noise. It’s all about breaking the problem into manageable pieces and letting the numbers guide you.
