Scenario planning that actually changes decisions

How CEOs can turn uncertainty into capital-allocation choices

For many executive teams, scenario planning has become a ritual: a workshop, a matrix, three or four possible futures, a polished deck, and then a return to the budget that was already on the table.

That is not good enough for the environment CEOs are now operating in.

South African CEOs are navigating a rare combination of cautious optimism and structural uncertainty: improving business confidence, uneven sector performance, geopolitical volatility, infrastructure constraints, AI disruption, tariff risk, cyber risk, climate transition pressure, and a cost of capital that still makes every major allocation choice consequential. The RMB/BER Business Confidence Index rose to 47 in Q1 2026, its highest reading since 2015 outside the immediate post-Covid recovery, but the improvement was not broad-based: manufacturing confidence fell while vehicle dealers, wholesalers and building contractors improved.

This is exactly the kind of environment in which scenario planning should matter. Yet too often it does not change the decisions that matter most: where capital goes, which investments are accelerated, which are paused, which businesses are protected, and which assumptions are no longer bankable.

The test of scenario planning is not whether the scenarios are interesting. The test is whether they change capital allocation.

PwC’s 29th Global CEO Survey captures the tension well. CEOs are less confident about short-term growth and more worried about macroeconomic volatility, cyber risk and geopolitical conflict, while still investing in AI, innovation and business-model reinvention. The survey found that 42% of CEOs say their companies have begun competing in new sectors in the past five years, and 32% say geopolitical uncertainty is making them less likely to make large new investments. PwC’s warning is direct: uncertainty should not freeze decision-making, because companies still making major investments are growing faster and achieving higher margins.

For African CEOs, the issue is even sharper. PwC’s Africa perspective reports that 81% of African CEOs expect economic conditions to improve in their own markets, but only 47% are confident about revenue growth over the next 12 months. On AI, 75% demonstrated strong commitment to adoption last year, but only 41% have clearly defined AI roadmaps and just 26% believe current investment levels are sufficient to deliver their AI goals.

That gap between intent and allocation is where strategy either becomes real or remains rhetoric.

Why scenario planning fails

Scenario planning usually fails for one of five reasons.

First, the scenarios are too generic. “High growth”, “low growth”, “disruption” and “stability” do not force a CEO, CFO or board to make different choices.

Second, the scenarios are not connected to a capital-allocation model. They describe possible futures, but they do not show how EBIT, cash conversion, working capital, capex, debt headroom, M&A capacity or ROIC would change.

Third, the process is dominated by risk avoidance. Teams ask, “What could go wrong?” but not, “What would we regret not doing?”

Fourth, decisions are still made through last year’s budget logic. McKinsey’s research on resource allocation found that only about half of surveyed executives said their companies effectively align budgets with corporate strategy, and only 53% said their organisations fully fund identified priorities.

Finally, scenario planning is separated from governance. The board sees the scenarios. The executive committee debates them. But the investment committee, budget cycle and performance scorecards continue largely unchanged.

BCG’s Laura Juliano captured the practical value of scenario planning when she said it is “the best method to prevent the stalling in decision-making” under uncertainty. But that only holds when scenarios are built to force decisions.

Start with the decision, not the scenario

The most useful scenario-planning question is not: “What might the world look like?”

It is: “Which capital-allocation choices are we struggling to make because the future is unclear?”

For a South African CEO, those choices might include:

Should we accelerate AI investment or wait for clearer returns?
Should we expand capacity despite soft consumer demand?
Should we localise supply chains or preserve global sourcing flexibility?
Should we invest in water, energy and logistics resilience as strategic infrastructure?
Should we pursue M&A while valuations are attractive, or preserve cash?
Should we protect core margins or invest through the cycle to gain share?
Should we enter adjacent sectors as industry boundaries blur?

Each of these is a capital question. Each should be tested against a small number of plausible futures.

A scenario-planning process that changes decisions works backwards from the capital agenda. It identifies the unresolved choices, models the value at stake, defines trigger points, and creates a set of pre-agreed moves.

The CEO’s four-scenario capital lens

Rather than creating abstract narratives, CEOs can frame scenarios around the two or three uncertainties that would most affect capital allocation. For many South African companies, four lenses are particularly useful.

1. Demand and margin scenarios

What happens if volume growth remains muted, but input costs, wages, logistics and compliance costs rise? What happens if demand recovers faster than expected, but customers remain price-sensitive? This determines pricing, capacity investment, operating leverage and cost transformation.

2. Cost-of-capital and balance-sheet scenarios

What happens if funding costs remain elevated, the rand weakens, or debt markets tighten? What if capital becomes cheaper faster than expected? This determines hurdle rates, gearing, dividend policy, buybacks, M&A appetite and capex pacing.

3. Technology and AI scenarios

What happens if competitors convert AI into measurable cost and revenue advantage faster than expected? What happens if AI remains fragmented in pilots and fails to scale? PwC’s global survey found that 56% of CEOs have seen neither higher revenues nor lower costs from AI, while only 12% report both revenue gains and cost reductions. This should force CEOs to distinguish between AI theatre and AI investment cases linked to value pools.

4. Geopolitical, trade and supply-chain scenarios

What happens if tariffs, trade fragmentation or regional conflict affect sourcing, export markets or customer affordability? Deloitte’s Fall 2025 Fortune/Deloitte CEO Survey found that 80% of surveyed CEOs were likely to implement cost-cutting measures and 63% planned little change to investment plans despite trade-policy uncertainty. The risk is that “little change” becomes inertia when the company actually needs selective acceleration and selective retreat.

Convert scenarios into capital-allocation choices

A useful scenario does three things.

It identifies no-regret moves: investments that make sense across most plausible futures. These may include cyber resilience, data quality, AI governance, customer analytics, energy resilience, water security, working-capital discipline, leadership capability and productivity improvement.

It identifies real options: small investments that preserve the right, but not the obligation, to scale later. These may include minority stakes, pilots with clear scale criteria, land options, supplier-development programmes, technology proofs of value, or market-entry beachheads.

It identifies big bets: investments that are attractive only under specific scenarios, but potentially decisive if those scenarios materialise. These require explicit trigger points, board alignment and a disciplined view of downside exposure.

BCG’s capital allocation research is instructive here. It argues that capital allocation may be the most critical way to translate strategy into action, yet its database of more than 10,000 listed firms found capex relative to revenue had fallen 10% over ten years while shareholder payouts and cash levels rose by more than a third. More importantly, top-third valuation performers invested about 50% more in capex than peers and achieved higher returns on assets and sales growth.

In other words, the answer to uncertainty is not blanket caution. It is better selectivity.

Build a scenario-adjusted capital stack

CEOs can ask the CFO and strategy team to classify the capital plan into five buckets.

Protect: mandatory investment to preserve licence to operate, compliance, safety, resilience and cyber integrity.

Productivity: automation, process redesign, procurement, shared services, AI-enabled efficiency and working-capital improvement.

Core growth: investments that defend or expand the current business model.

Options: smaller investments that create future flexibility.

Transformation bets: larger moves into new business models, sectors, platforms, acquisitions or capabilities.

The executive team should then ask four questions for each bucket:

What happens to this investment under each scenario?
What is the cost of delaying it by 12 months?
What evidence would make us accelerate, pause or stop?
Who has authority to reallocate capital when the trigger is reached?

This is where scenario planning becomes operational. McKinsey recommends identifying the role of each business in the strategy, narrowing focus to the ten to 30 most important enterprise initiatives, matching the budget to the long-term financial plan, and building in-year flexibility so resources can be reallocated during the year.

The in-year flexibility point is crucial. In a volatile environment, the annual budget is too slow to be the only capital-allocation mechanism.

Governance: the missing link

Scenario planning should culminate in a CEO-led capital forum, not a strategy offsite.

The CEO, CFO and a small investment committee should meet regularly to make allocation decisions, not merely review progress. McKinsey argues that monthly investment committee meetings should be for decisions, including allocating stage-gated funds, discontinuing projects that are unlikely to meet objectives, and approving new projects that emerge after the annual planning cycle. It also suggests a strategic reserve of unallocated funds, typically 5% to 20% depending on industry volatility.

This is especially relevant in South Africa, where opportunities and shocks can both emerge quickly: a logistics improvement, a regulatory shift, a distressed acquisition, an export-market opening, an energy or water disruption, or a sudden change in consumer sentiment.

The board’s role should also change. Instead of asking management for “the forecast”, boards should ask:

Which assumptions would make this capital plan wrong?
Which investments are robust across scenarios?
Where are we overexposed to one view of the future?
What are the trigger points for reallocating capital?
What have we stopped funding because the scenario evidence has changed?

The leadership shift

EY’s South Africa CEO Outlook says South African CEOs are entering 2026 with renewed confidence, moving from stabilising operations to scaling transformation and investment, while reaffirming South Africa as a priority investment destination amid geopolitical volatility. PwC South Africa’s Hannelie Gilmour puts the leadership challenge succinctly: “What’s needed now is decisive and inspirational leadership that matches intent with action.”

That is the heart of scenario planning.

The purpose is not to predict the future. It is to make today’s decisions more resilient, more explicit and more value-creating.

For CEOs, the practical challenge is to turn uncertainty into a portfolio of choices: protect the core, fund productivity, create options, place selective bets, and build the governance rhythm to move capital as evidence changes.

The companies that win will not be those with the most elegant scenarios. They will be those whose scenarios changed what they funded, what they stopped, what they accelerated and what they were prepared to do before the market forced their hand.
