Nearly 40% of marketers surveyed say their organizations struggle to connect Marketing Mix Model (MMM) outputs to real-world business decisions, according to a recent Harvard Business Review Analytic Services report. 1 Since introducing Meridian, our open-source MMM, we’ve been focused on addressing this long-standing challenge by making its insights accessible.
Today we're introducing Scenario Planner to help decision makers and data scientists alike bridge the gap between analytics and planning.
Scenario Planner is a user-friendly interface that allows marketers to experiment with different budget scenarios and see real-time ROI estimates — no coding required. It transforms the conversation from a look back at what happened to a collaborative plan for what’s next, regardless of technical expertise.
By connecting marketing teams with the Scenario Planner, we’re making it easier than ever to use measurement insights to inform business decisions. Meridian has always been transparent; now, it’s truly accessible.
