Welcome to my blog, where I delve into the dynamic world of Decision Sciences, focusing especially on its role in enhancing strategic decision-making within Marketing organizations. Here, I’ll share insights, thoughts, and occasionally, practical resources such as links to code and models on GitHub to deepen understanding and illustrate key concepts. My posts will venture into areas I’m passionate about, connecting the dots between Advanced Analytics, Data Science, and the burgeoning field of Decision Sciences. My writing might at times echo a manifesto for the Decision Scientist. This is intentional, as I am exploring and advocating for the pivotal role that Decision Scientists can and should play in a business world increasingly driven by Generative AI and a data-savvy workforce.
Expect a non-traditional approach as I share these thoughts and ideas. This blog isn’t just about posts; it’s a fluid, evolving narrative where concepts interlink and expand over time, reflecting continuous refinement and growth in this fascinating field. Join me on this journey as we explore the cutting-edge of Decision Sciences together.
AI has leveled the playing field of analysis. Every enterprise can now generate models, dashboards, and insights at scale. But when analytic power becomes universal, advantage shifts elsewhere—to how well organizations decide with it. In the GenAI era, success will hinge less on analytic sophistication and more on decision capacity:…
Keep readingAI doesn’t erase human judgment—it exposes its importance. As AI streamlines analysis, advantage shifts upstream to decision capacity—how well organizations make choices. Decision Scientists connect AI-powered insights to strategy by clarifying options, quantifying trade-offs, and closing the loop with evidence and feedback. When sophisticated insights are widely available, the winners…
Keep readingExecutive Takeaway: Decision Debt exists in every organization—it’s only a question of degree. It exposes the hidden costs of unclear or poorly grounded choices: confidence built on assumptions that becomes misdirection, wasted effort, delay, rework, and lost trust. While the metrics and framework introduced is conceptual, it helps leaders see…
Keep readingEvery organization faces hidden bias in its decision-making—from confirmation bias and groupthink to sunk-cost fallacy. This post includes a practical table of the most common cognitive biases and how to counter them, briefly outlining how a Decision Science approach builds stronger processes that lead to clearer, smarter, and more reliable…
Keep readingExecutive Takeaway: Markov models matter because they don’t just show where customers or deals are today—they reveal how groups are likely to move tomorrow—toward growth, retention, or churn. They reveal not just the what (likelihood of churn, revenue forecast) but the pathways—how customers and deals actually flow over time. That…
Keep readingThe way we do data science has changed forever. GenAI makes coding frictionless—but without structure it gets messy and invites slippage down rabbit holes. I’ve been refining CRISP-AI, a lightweight process (inspired by CRISP-DM) to work smarter with AI.
Keep readingData teams are no longer just service providers—they’re becoming strategic partners in decision-making. But as business fluency rises on one side, a growing data literacy gap is emerging on the other. This shift is creating tension—and opportunity. This isn’t a flaw—it’s the future.
Keep readingMy latest post discusses optimizing Marketing spend using reinforcement learning (RL) and an LLM as a meta-controller—an approach we term Agentic-AI. It details creating a custom RL environment for managing multiple Marketing channels and describes how the LLM meta-controller orchestrates the overall learning process. Rather than making spend decisions directly,…
Keep readingMy latest post explores using a large language model (LLM) to directly control a reinforcement learning (RL) environment for optimizing Marketing spend. The LLM actively makes decisions step by step. Unlike typical RL applications, this setup allows real-time interaction and showcases the LLM’s reasoning process while determining optimal actions.
Keep readingDrawing inspiration from Rumi’s timeless insight—“When light returns to its source, it takes nothing from what it has illuminated”—this blog post explores how descriptive analytics reveal historical trends while prescriptive analytics chart future actions. Discover how these complementary approaches drive clarity and remarkably empower effective decision-making in today’s data-driven world.
Keep readingCheck out my latest blog post, where I set up a simple scenario to show how a reinforcement learning (RL) agent finds the sweet spot in marketing spend—laying the groundwork for Agentic AI. Whether you’re curious about RL fundamentals or integrating LLMs, this mini use case offers valuable insight into…
Keep readingLarge Language Models (LLMs) are powerful, but they don’t always surface the most relevant or up-to-date information for your needs. Retrieval-Augmented Generation (RAG) changes that by integrating real-time, domain-specific insights, ensuring AI-generated responses are always up-to-date and relevant. Instead of relying on generic training data, RAG personalizes AI with custom…
Keep readingThis latest post explores the distinctions between data-informed, data-driven, and decision-driven approaches to analytics in organizations. It highlights that while many claim to be data-driven, they often over-rely on intuition. Transitioning to decision-driven analytics, which emphasizes defining decisions first and aligning data accordingly, is crucial for effective strategy and impactful…

This blog introduces the Decision Science Pre-Analysis Framework, a structured approach to overcoming the Last-Mile Problem in analytics, ensuring insights don’t just inform but actively drive decision-making and meaningful action.
Keep readingAs a new father, I saw an unexpected parallel between sleep training my baby and decision-making in marketing: intermittent reinforcement. Just like a baby learns to keep crying if it sometimes works, businesses fall into the trap of justifying bad habits based on occasional success. This post explores how Decision…
Keep readingThis blog explores how saturation curves and incremental returns can guide optimal marketing spend allocation. Using scenario analysis, I show why relying on averages like ROAS can mislead decision-makers. Learn how to balance spend across channels, avoid saturation, and unlock growth by reallocating budgets to underutilized opportunities for higher returns.
