When a chart is not a decision
A rising conversion line can hide a definition change, a seasonal spike, or a sample that excludes the users who matter. Analysts who treat the chart as the decision skip the harder work of naming assumptions.
In our studios we ask three questions before any recommendation: what population is counted, what time window is implied, and what counter-evidence would falsify the story. Those questions sound basic until a stakeholder meeting is already leaning toward a ship date.
If your team only debates colors on a slide, schedule a short critique session before the next roadmap lock. Clarity about uncertainty is a professional deliverable, not a weakness.
