The Inertia Problem: Why Budgets Barely Change

Research by McKinsey spanning thousands of companies over 15 years found that the average company reallocates only 8% of its capital from one year to the next across business units. The remaining 92% stays where it was, regardless of whether the receiving business units are growing, declining, or stagnating. This inertia is the single biggest drag on strategic performance.

The reasons are human, not analytical. Resource allocation is a political process as much as a strategic one. Business unit leaders fight to protect their budgets. Historical allocation creates expectations. Reducing funding for a unit feels like a judgment on its leadership. And the people who allocate resources — CFOs and CEOs — face intense social pressure from the people whose budgets they would need to cut.

What Active Reallocation Looks Like

The companies that outperform — the ones McKinsey's research found grow 30% faster and generate higher returns — reallocate at least 30-50% of capital across business units over a 10-year period. That is roughly 3-5% reallocation per year, compounding over time.

Active reallocation does not mean dramatic annual restructuring. It means: incrementally shifting resources from lower-growth to higher-growth areas, funding new strategic initiatives from savings in declining businesses, and being willing to eliminate or scale back programs that are no longer strategic priorities.

The key behavior is not the size of any single reallocation but the consistency. Companies that reallocate resources every year, even in small amounts, dramatically outperform companies that maintain stable allocations and make large, disruptive changes every 5-7 years.

Breaking the Inertia: Practical Approaches

Zero-based resource allocation: Instead of starting with last year's budget and adjusting incrementally, start from zero each year and require every business unit to justify its allocation based on strategic contribution and growth potential. This is not easy, but it breaks the assumption that last year's allocation is this year's baseline.

Strategic tournaments: Have business unit leaders compete for incremental investment by presenting growth cases. A dedicated pool of capital — say, 10-15% of the total budget — is allocated through competitive evaluation rather than historical entitlement. This creates a market-like mechanism for capital allocation.

Separate growth and maintenance budgets: Require each business unit to separately identify the capital needed to maintain current operations and the capital needed to grow. Maintenance budgets can be relatively stable. Growth budgets should be actively allocated based on strategic potential. This separation makes the reallocation conversation more precise and less threatening.

Tie allocation to strategic reviews: Conduct resource allocation discussions immediately after strategy reviews, not separately. When the strategic assessment shows that Market A is growing three times faster than Market B, the resource allocation implications are obvious. Separating these conversations allows political considerations to override strategic logic.
