Why most organizations need better assumptions, not better algorithms Forecasting is one of the most widely attempted, and most consistently disappointing, analytics activities. Organizations invest in sophisticated models, complex algorithms, and external data sources, only to find that forecasts remain inaccurate, ignored, or overridden. Over time, leaders grow skeptical. Forecasts become something to be reviewed, not relied upon. The problem is rarely mathematical. Forecasting fails because organizations overestimate the value of complexity and underestimate the value of discipline. Why Forecasting Breaks Down in Practice At an executive level, forecasting failure usually appears as “noise.” Forecasts change frequently. Confidence intervals are wide. Scenarios proliferate. Leaders respond by discounting forecasts altogether. What is less visible is the root cause: forecasts are often built without agreement on what they are meant to support. A forecast without a decision context is just a projection. Forecasts Exist to Support Decisions, Not to Be Right A critical reframing is necessary. The purpose of a forecast is not accuracy in isolation. It is usefulness in decision-making. A forecast that is directionally correct and consistently used creates more value than a precise forecast that no one trusts. When this principle is ignored, teams optimize for technical metrics while leaders disengage. The Power of Simple Models Simple forecasting models, trend-based projections, moving averages, regression on key drivers, are often dismissed as unsophisticated. In practice, they outperform complex models for one reason: they are understandable. When leaders understand the assumptions behind a forecast, they engage with it. They challenge it constructively. They use it. Complex models obscure assumptions. When forecasts surprise, trust collapses. Simplicity creates transparency. Transparency creates adoption. What “Simple” Actually Means Simple does not mean naive. A simple forecasting model: It avoids unnecessary features, excessive segmentation, and opaque logic. This discipline matters more than algorithmic sophistication. Why Forecast Accuracy Is a Misleading Goal Forecast accuracy is often treated as the primary success metric. In reality, accuracy is unstable. Markets change. Behavior shifts. External shocks occur. No model can anticipate everything. When accuracy is overemphasized, teams become defensive. Forecasts are hedged. Confidence erodes. A more useful metric is forecast impact: These outcomes matter more than statistical precision. The Role of Governance in Forecasting Forecasts fail when they exist in isolation. Effective forecasting requires: Without governance, multiple forecasts compete. Leaders choose the one that fits their narrative. Forecasting loses credibility. Governance does not constrain forecasting; it anchors it. Why Overriding Forecasts Is Not a Failure Leaders often override forecasts, and that is not inherently bad. What matters is whether overrides are explicit and documented. When overrides are hidden, learning stops. When they are visible, models improve. Assumptions are refined. Trust grows. Forecasting is a dialogue, not a decree. A Useful Executive Question Instead of asking, “Is this forecast accurate?”, a better question is: “What would we do differently if this forecast is directionally right?” If no action changes, the forecast is not adding value, regardless of accuracy. The Executive Takeaway For CXOs, the deeper truth is this: Organizations that embrace this build forecasting capabilities that leaders actually use. Those that do not continue to invest in models that impress technically, and disappoint operationally. Let’s Connect.
