You are a product analyst on a B2B workforce platform. Last month, one of the core performance KPIs fell 14% versus the prior month, but the same metric has shown similar dips in the same period over the last two years. The business wants to know whether this is normal seasonality or a real issue tied to a recent product or workflow change.
How would you investigate whether a drop in performance is due to seasonality or a real issue?
