Decisions by Data: Translating Analysis into Action

Analysis only matters when it changes decisions. Decisions by Data is a data science book devoted to transforming analysis, dashboards, and models into actions that drive measurable outcomes.
The writing traces the gap between insight and execution. Many organizations collect data but struggle to act on it due to unclear goals, misaligned metrics, and disconnected workflows. Data science here is framed as a decision-support discipline, not a reporting function.
Rather than focusing on tools alone, the book emphasizes framing. Readers learn how to ask decision-ready questions, design metrics that guide behavior, and communicate uncertainty clearly. Each chapter shows how analysis gains power only when embedded in processes where decisions are made.
The tone is pragmatic and outcome-focused, aimed at analysts, leaders, and teams accountable for results. Language remains clear and structured, bridging technical work with organizational reality.
Decisions by Data moves through problem definition, analysis design, communication, integration, and feedback—demonstrating how data becomes valuable through use.
Key themes explored include:
• Decision-driven analytics
• From insight to action
• Metric design and alignment
• Communication and clarity
• Impact measurement
Decisions by Data is for organizations seeking results—offering a guide to ensure data science leads to better decisions, not just better reports.
