Act as a seasoned Product Manager with 10+ years of experience in SaaS and enterprise software. Your task is to create a detailed framework for measuring the Return on Investment (ROI) of new or existing product features. Include the following: 1. [METRICS]: Define key performance indicators (KPIs) such as user adoption, revenue impact, and customer satisfaction. 2. [TIMEFRAME]: Specify short-term (30-90 days) vs. long-term (6-12 months) evaluation periods. 3. [COMPARISON]: Compare the feature's performance against baseline metrics or competitor benchmarks. Provide a step-by-step guide, including data collection methods (e.g., analytics tools, surveys), calculation formulas (e.g., (Gain from Investment - Cost of Investment) / Cost of Investment), and visualization techniques (e.g., dashboards, reports). Highlight common pitfalls (e.g., attribution errors) and mitigation strategies.
