This document outlines five steps for improving marketing lead data to increase revenue: 1) Set a baseline by auditing existing data, identifying errors and opportunities for improvement. 2) Organize a cross-departmental team and projects with goals and metrics. 3) Make improvements starting with simple, low-cost projects focused on data capture, processing and sales-marketing coordination. 4) Measure results including costs, data quality changes and business impacts. 5) Repeat the process by identifying new opportunities and maintaining past improvements through ongoing measurements. Quality data programs prepare teams for additional cooperation and maximize the value of integrated marketing systems.
