The futurist’s paradox

In plain terms, we live in what military planners first called a VUCA world — volatile, uncertain, complex and ambiguous. Volatility means shocks arrive suddenly, from tariffs to technology breakthroughs. Uncertainty means forecasts are fragile and probabilities keep shifting. Complexity reminds us that every part of the system is entangled, so one disruption ripples quickly across many domains. And ambiguity is the reality that signals are rarely clear; leaders must act even when information is incomplete.

For business leaders, this is more than jargon — it is the daily environment in which they operate. In such conditions, static plans age poorly the moment they are printed.

Scenario planning was intended to provide foresight, yet most organizations still treat it as a static exercise — snapshots of possible futures crafted in annual cycles. The paradox is evident: the very tool designed to prepare leaders for disruption often leaves them unprepared.

A brief history of scenario planning

  • 1950s – Cold War origins: RAND strategist Herman Kahn developed the idea of “thinking the unthinkable” to stretch defense planning beyond the probable. (RAND Corporation archives).
  • 1970s – Corporate adoption: Royal Dutch Shell famously used scenarios to anticipate the 1973 oil shocks. As Wilkinson noted in Living in the Futures: “Shell-style scenario planning has never really been about predicting the future. Its value lies in how scenarios are embedded in—and provide vital links between — organizational processes…It has helped break the habit…of assuming that the future will look much like the present.”
  • 1990s – Popularization: Peter Schwartz’s The Art of the Long View brought the discipline into boardrooms worldwide. Schwartz explained: “Scenarios are not forecasts; they are ways to open our minds to look at different alternatives of the future.” — Schwartz, The Art of the Long View, Doubleday Currency, New York, 1991.
  • 2000s–today – Consulting frameworks: McKinsey, BCG, Bain and others embedded scenarios into their toolkits. As McKinsey observed: “The typical approach of many companies…will be far too slow to keep up in such turbulence.”

The intellectual foundations remain strong. The practice, however, has lagged behind the velocity of today’s change.

Why static planning fails today

  • Analysis paralysis. Outputs take months — often outdated before use. McKinsey warned: “The typical approach of many companies…will be far too slow to keep up in such turbulence.”
  • Cognitive bias. Leaders overweight familiar trends. As J. Peter Scoblic wrote in Harvard Business Review: “Scenario planning does not help us figure out what to think about the future. It helps us figure out how to think about it.”
  • Disconnection from execution. Scenarios often stay in slide decks while real work happens in ERP, PPM or Agile tools — never connected in practice. Gartner research has shown that most scenario exercises fail to link to resource allocation.
  • False comfort. Scenarios can create an illusion of readiness. Scoblic also noted: “Its aim is not to predict the future but rather to make it possible to imagine multiple futures in creative ways that heighten our ability to sense, shape and adapt to what happens in the years ahead.”

Industry failures that prove the point

“Plans are useless, but planning is indispensable.” —Dwight D. Eisenhower

  • Retail: Annual plans assumed stable shipping. When container costs spiked weekly, inventories ballooned.
  • Automotive: EV roadmaps faltered when chip shortages stopped production and short-term dependencies were ignored.
  • Finance: Annual stress tests missed the rapid 2022–23 rate hikes, leaving banks scrambling.
  • Pharma: COVID accelerated development timelines; firms without agile scenario models lagged.
  • Energy: Utilities misread demand curves as renewable costs collapsed faster than expected.

Scenarios existed — but they weren’t alive.

Toward continuous foresight

The answer is not abandonment, but evolution: Continuous foresight. A living system that links strategic vision to tactical execution, updated continuously.

Four principles

  1. Sense signals from noise. Always-on scanning for tariffs, cyber threats and supply disruptions. Futurist Jamais Cascio noted: “The more noise you collect, the harder the signal.”
  2. Analyze with a digital twin. Driver-based models map macroeconomic changes (such as energy prices and interest rates) to operational metrics. BCG found that living models can halve response times.
  3. Act with triggers. Tie responses to thresholds (e.g., freeze hiring if growth dips below 10%). Bain reported that firms with pre-defined triggers pivoted in weeks, not months.
  4. Monitor with rolling forecasts. Deloitte research found that “living forecasts” were the top factor in organizational resilience.

The technology prerequisite

“Without data, you’re just another person with an opinion.” —W. Edwards Deming

Continuous foresight cannot live in spreadsheets. It requires:

  • Real-time data integration across finance, supply chain, HR and project tools.
  • Constraint and dependency modeling — the math of resources, budgets and timelines.
  • AI-enabled analytics to cut modeling time from weeks to hours.
  • Collaboration hubs ensuring one shared truth.

This is not about ripping out existing systems. It’s about layering a safe place to plan on top of them — ingesting data, running the math of change and feeding insights back. As one operations leader put it: “Our PPM tells us what we have. Our spreadsheets tell us what we hope for. We needed something that told us what we could actually deliver if the ground moved.”

Practical guide: What CIOs should demand

CapabilityWhy It MattersQuestions to Ask
Real-time data feedsReflects today’s reality.Can it ingest ERP, PPM and Agile data continuously?
Driver-based modelingConnects macro changes to operations.How are dependencies modeled mathematically?
Trigger-based actionsTurns foresight into decisions.Can actions activate automatically at thresholds?
Rolling forecastsKeeps plans alive.Does it update weekly/monthly?
Cross-functional visibilityBreaks silos.Do execs and delivery teams share one view?
Ease of use & speedAvoids paralysis.Can new scenarios be modeled in hours?
Constraint & dependency modelingCaptures feasibility.Does it simulate using real constraints, not just assumptions?

CIO takeaways

  • Annual planning is obsolete in a world of weekly shocks.
  • Disconnected scenarios create blind spots.
  • The missing link is a layer that applies math to real-time data.
  • CIOs should demand foresight systems that are alive, adaptive and continuous.

Building muscle memory for change

Scenario planning is not a ritual but a discipline of preparation — a way to make organizations more resilient in the face of uncertainty. Yet too often it has become theater: annual binders of scenarios that reassure boards but leave operators blind.

CIOs can change that. The mandate now is to build muscle memory for change: a foresight capability that continuously senses, models and adapts. The steps are pragmatic:

  1. Shorten the cycle. Stop treating foresight as a once-a-year event. Replace static plans with rolling, always-on forecasts.
  2. Run the math. Make constraint and dependency modeling a core input. Strategy without feasibility is just wishful thinking.
  3. Connect strategy to execution. Ensure that scenarios are tied to real triggers in PPM, ERP and Agile systems. Without that loop, foresight remains theoretical.
  4. Create a safe place to plan. Leaders need an environment where they can test “what ifs” without breaking live systems — where trade-offs are visible before they become mistakes.

Enterprises don’t need to rip and replace what they already have. The real opportunity is a complementary layer — an analytical backbone that ingests data from existing systems, continuously runs the math of change and feeds back clear options.

Think of it like navigation. Traditional planning is a paper map — valuable but outdated the moment you unfold it. Continuous foresight is more like Google Maps: always connected, recalculating routes in real time when a road closes, traffic builds or a new opportunity opens up. The destination doesn’t change, but the way you get there adapts constantly.

The future will not wait for the next annual review. The only question is whether CIOs will.
