Three Horizons of Growth: McKinsey's Model Explained

The three horizons of growth is a strategic framework that helps organizations run their core business today while deliberately building the businesses that will replace it tomorrow. If your leadership team keeps defaulting every dollar to near-term operations, this model gives you a structured argument for why that's a slow way to lose.

What is the three horizons of growth model?

The three horizons of growth model is a portfolio management framework that divides a company's activities into three concurrent time horizons, each requiring a distinct management mindset, investment logic, and success metric.

Consultants Mehrdad Baghai, Stephen Coley, and David White introduced the model in their 1999 book The Alchemy of Growth, published by McKinsey. The core insight is simple but powerful: well-run companies don't choose between protecting existing revenue and building new businesses. They do both at the same time, across three clearly defined horizons.

Key Facts

• The 70/20/10 rule, popularized by Google, suggests allocating roughly 70% of innovation resources to core business (H1), 20% to adjacent opportunities (H2), and 10% to transformational bets (H3). Google attributed its sustained growth to this split. (Google, 2011; Harvard Business Review, 2012)
• A 2023 McKinsey survey found that companies effectively balancing all three horizons generated 2x the total shareholder return over 10 years compared to peers focused primarily on H1 activities.
• PwC's Global Innovation Survey (2023) found that 61% of executives say their organization's biggest innovation weakness is failing to invest sufficiently in long-term (H3) bets because short-term pressure consistently wins budget battles.

The three horizons explained

Think of the three horizons as three overlapping growth curves running in parallel, not a sequential relay race. Each horizon exists simultaneously inside the organization.

Horizon 1: Defend and extend the core

H1 is where almost all near-term revenue lives. The job here is to protect margins, serve existing customers well, and squeeze efficiency out of proven processes. But "defend and extend" doesn't mean stagnate. H1 teams should still look for incremental improvements: faster onboarding, better support, modest feature upgrades. The risk in H1 is treating it as the only horizon worth funding.

Horizon 2: Build emerging businesses

H2 is where past H3 experiments that showed real signal get properly resourced. These are businesses that already have some proof: early customers, a working prototype, or a validated market assumption. The challenge here is applying enough structure to scale without smothering the initiative with H1 management norms. H2 teams need different KPIs, different hiring profiles, and often a separate P&L.

Horizon 3: Create viable future options

H3 is not a skunkworks fantasy lab. It's a deliberate portfolio of early-stage options that give the business the right to play in future markets. Most H3 experiments will fail. That's expected. The goal is to generate enough attempts that two or three survive to become H2 in three to five years. H3 budgets are small, teams are lean, and success means learning fast, not shipping at scale.

How to allocate resources across horizons

The most common allocation benchmark is the 70/20/10 split: 70% of innovation resources to H1, 20% to H2, and 10% to H3. Google made this famous, but the right ratio depends on your industry's pace of change and your current competitive position.

The common trap is letting H1 absorb resources meant for H2 and H3 during any short-term financial pressure. This is rational in the quarter. But companies that consistently cut H2 and H3 in downturns find themselves with a healthy core and no pipeline of future businesses when the market eventually shifts. The BCG matrix can help you identify which parts of the H1 portfolio are cash cows vs. dogs, freeing up capital you can redeploy to longer horizons.

A second common mistake: treating H2 and H3 with H1 management tools. Applying quarterly revenue targets to an H3 experiment kills it before it can learn. Each horizon needs its own success criteria.

Three horizons vs other growth frameworks

The three horizons model is a better fit when you need a long-range portfolio view across business stages. The Ansoff matrix is more useful when you're debating a single directional choice: new market, new product, or both. The BCG matrix helps you optimize what you already have rather than plan what to build next. Most leadership teams use all three in sequence: Ansoff to set direction, BCG to triage the existing portfolio, and three horizons to frame the full investment story for the board.

For execution, pair the three horizons with your OKR framework. H1 OKRs focus on performance; H2 OKRs focus on traction milestones; H3 OKRs focus on learning outcomes.

Benefits and criticisms

Benefits

• Gives leadership a shared language for talking about short-term operations and long-term bets without defaulting to "we can't afford innovation right now."
• Prevents the common failure mode of treating every business unit with the same management logic and the same success metrics.
• Forces the board to explicitly fund H2 and H3 rather than leaving them to survive on whatever budget H1 doesn't consume.
• Works at the corporate level (allocating capital across business units) and at the business unit level (allocating budget across product lines).
• Pairs cleanly with scenario planning to stress-test H3 assumptions against different futures.

Criticisms

• Fixed time horizons can mislead. The original model assumes H3 plays out over five to seven years. In software markets, competitive disruption can compress that to 18 months. A framework built for industrial conglomerates doesn't always translate to digital businesses.
• The model describes categories of investment but gives limited guidance on how to choose which specific H2 or H3 bets to fund. You still need criteria for picking experiments.
• The 70/20/10 split is widely cited but rarely validated for any given industry. Applying it mechanically without calibrating to your competitive environment is a mistake.
• Some critics argue the model can create bureaucratic silos: "H3 teams" that are too protected from market feedback because they're told not to worry about revenue yet.
• It doesn't address the organizational capability gaps that often block H2 and H3 success: different talent profiles, different governance, different risk appetite. The McKinsey 7S framework is a useful companion for diagnosing those structural barriers.

How to apply the three horizons model

Step 1: Audit your current portfolio

Map every significant initiative, product, and business unit to one of the three horizons. Be honest about where revenue actually comes from today. Most companies discover they have 90% or more of their activity in H1, a small cluster of initiatives that probably belong in H2, and almost nothing in H3.

Step 2: Set explicit investment targets for each horizon

Don't let budget allocation happen by default. Use the 70/20/10 starting point, calibrate it to your industry velocity, and then make an explicit board-level decision. Write it down. The act of committing to an H2/H3 allocation is more important than the exact percentages.

Step 3: Apply different management rules to each horizon

H1 uses standard operating metrics: revenue, margin, churn, NPS. H2 uses growth and traction metrics: customer acquisition cost, product-market fit signals, revenue ramp. H3 uses learning metrics: experiments run, assumptions validated, prototypes shipped. Applying H1 metrics to H3 is the fastest way to kill it. The balanced scorecard is a useful tool for building out the right measurement layer for each horizon.

Step 4: Create distinct governance for H2 and H3

H2 and H3 teams often need separate budget cycles, different reporting lines, and more autonomy from the core business. Without explicit governance protection, H1 will absorb their resources whenever quarterly targets are under pressure. Consider a dedicated innovation committee that owns H2/H3 decisions and reports directly to the CEO or board.

Step 5: Build a pipeline of H3 experiments

H3 is not a single moonshot. It's a portfolio of small bets. Set a minimum number of active H3 experiments at any time (five to ten is a reasonable starting range for mid-size companies). Track them with learning objectives rather than revenue targets. Review quarterly. Promote the ones showing signal to H2 and kill the rest cleanly. The value proposition canvas is a good tool for stress-testing H3 hypotheses before committing meaningful resources.

Three horizons example

This worked example shows how a B2B workflow software company might map its current and planned initiatives across all three horizons.

In this example, the company is allocating roughly 75% to H1, 20% to H2, and 5% to H3. The next strategic review should focus on whether H3 is underfunded given how quickly AI is changing their competitive landscape.

Frequently asked questions

What is the three horizons of growth model?

The three horizons of growth is a portfolio management framework developed by McKinsey consultants Baghai, Coley, and White in their 1999 book The Alchemy of Growth. It divides organizational investment into three parallel time horizons: H1 (defend and extend the core business), H2 (build emerging businesses with proven early traction), and H3 (create viable options for future growth). The model's central argument is that companies must manage all three simultaneously rather than treating them as sequential phases.

What is the 70/20/10 rule in the three horizons model?

The 70/20/10 rule is a resource allocation heuristic that suggests directing 70% of innovation resources to H1 (core business), 20% to H2 (emerging businesses), and 10% to H3 (future options). Google popularized the split in 2011 as part of their public innovation philosophy. The percentages are a starting point, not a fixed prescription. Companies in fast-moving markets may shift more toward H2 and H3; companies with dominant but threatened core businesses may need to protect H1 more aggressively.

How do the three horizons differ from the Ansoff matrix?

The Ansoff matrix helps you choose a single growth direction: deeper into existing markets, into new markets, with new products, or both (diversification). The three horizons model is a portfolio tool that frames how you allocate resources across multiple growth bets happening simultaneously at different stages of maturity. Use Ansoff to pick a direction; use the three horizons to balance investment across all the directions you're already running.

Is the three horizons model still relevant in fast-moving markets?

The model's core logic, running H1, H2, and H3 simultaneously, remains sound. But the fixed time frames need calibration. In software and AI-driven markets, what looks like an H3 experiment can become an H1 competitive threat in 18 months rather than seven years. Teams working in high-velocity environments should shorten the horizon windows and run more H3 experiments in parallel to stay ahead of compression. Pairing the model with scenario planning helps stress-test which H3 bets to prioritize.

What's the biggest mistake companies make with this framework?

The most consistent failure is letting H1 absorb H2 and H3 budgets under short-term financial pressure. This feels rational in the moment but creates a pipeline drought three to five years later. The second most common mistake is applying H1 management logic (quarterly revenue targets, established governance) to H2 and H3 initiatives before they're ready for it. Both errors starve future growth in ways that don't show up on the income statement until it's too late to fix quickly.

---

Strategic growth requires running three races at the same time, at three different speeds, with three different rules. The three horizons model doesn't make that easy. But it gives leadership teams a shared map so they can at least agree on what race each initiative is in and what winning looks like for each one. Combine it with the VRIO framework to check whether your H2 and H3 bets are built on capabilities competitors can't easily copy.
