Data-driven decision-making has the power to transform businesses, translating insights into actionable strategies that drive growth, innovation, and enhanced customer satisfaction. However, many organizations fail to fully realize this potential due to insufficient assessment and planning. To address this challenge, we introduce the Data Analytics Functionality Index (DAFI), a tool that empowers organizations to make informed decisions about their data analytics initiatives. Similar to the Nutri-Score system for evaluating nutritional value, DAFI provides a standardized, visual assessment of a project's functionality and potential impact.
