# Apply Surplus Reallocation

Identify areas generating surplus above optimal level and actively redirect those resources to deficit areas — because the human default is to pile more into winners and starve laggards, and that default destroys portfolio balance and long-term sustainability.

## Why This Is Best Practice

道德经 Chapter 77 (Laozi, ~6th–4th century BC):

> 天之道，损有余而补不足。人之道，则不然，损不足以奉有余。

"The way of heaven reduces surplus and supplements deficiency. The way of humans does the opposite — takes from the deficient to serve the surplus."

**Why best:** Laozi identifies this as the distinguishing feature of self-sustaining systems: they actively harvest from areas above optimum and redirect to areas below. Human systems do the reverse — over-invest in what's already working, under-invest in what's behind — until the imbalance becomes critical. The principle is not redistribution for fairness; it is rebalancing for long-term system health.

**BCG matrix (Bruce Henderson, Boston Consulting Group, 1970):** The most widely adopted portfolio management framework in corporate strategy. The explicit mechanics: Cash Cows (high market share, mature market, surplus cash generation) are intentionally constrained — reinvestment is capped at the level needed to maintain share, and surplus is redirected to Stars (high growth, high investment need) and to funding future Question Marks. The framework formalizes 损有余而补不足 as portfolio policy: harvest surplus from over-performers, redirect to deficit areas. Used by McKinsey, BCG, Bain, and standard in Fortune 500 strategy processes globally.

**Toyota heijunka (平準化, production leveling):** When one production line has surplus capacity relative to demand, workers and machines are reallocated to lines running below capacity. The principle: do not let any area accumulate idle surplus while other areas have deficits. Core pillar of the Toyota Production System; the operational mechanism that enabled Toyota to achieve 1/10th the defect rate and 1/3rd the inventory of American automakers by the 1980s. Adopted in Lean manufacturing globally across automotive, electronics, and consumer goods.

**Amazon internal capital allocation:** Amazon's documented practice of reallocating engineering teams and capital from established businesses to new investments. Amazon Web Services was built by redirecting surplus engineering capacity from retail infrastructure. The pattern — cap reinvestment in mature businesses at their optimal level, redirect surplus to early-stage bets — is explicit in Jeff Bezos's shareholder letters (1997–2021). Google follows the same model: Google Ads surplus funded YouTube, Android, Google Cloud, and later Waymo and DeepMind.

**Portfolio rebalancing (Harry Markowitz, 1952; institutional standard):** Modern Portfolio Theory establishes that over time, asset classes drift from target allocations — winners exceed targets (surplus), laggards fall below (deficit). The optimal response: rebalance by selling surplus positions and buying deficit positions. Vanguard Research (2019) demonstrated that systematic rebalancing to targets outperforms over-concentrating in winners over 10+ year horizons, because it captures mean-reversion premium. Standard practice at Vanguard, Fidelity, BlackRock, and all major institutional asset managers globally.

**Kelly criterion (John Kelly, 1956; popularized by Ed Thorp):** Optimal bet sizing formula: bet size = edge / odds. This explicitly prevents over-allocation to any single position regardless of past wins. The mathematical result: Kelly-optimal portfolios rebalance continuously, capping investment in winners and maintaining allocation to positions with positive expected value. Standard in quantitative investing, professional poker, and sports betting analytics.

**Why distinct from `apply-strategic-sacrifice`:** apply-strategic-sacrifice addresses one-time trade-offs — give up something of lower value to acquire something of higher value. It does not apply as ongoing policy and does not involve harvesting surplus from one area to redirect to another. apply-surplus-reallocation is a continuous cycle: identify surplus → harvest → redirect to deficit → repeat. The two skills address fundamentally different mechanisms.

**Why distinct from `apply-peak-exit`:** apply-peak-exit addresses exit timing — when to stop a winning position before it peaks. It does not address where the harvested resources go, and it is triggered by timing signals, not surplus-vs-deficit diagnosis. apply-surplus-reallocation is not about stopping a winner — it is about managing the level of investment across a portfolio.

**Why distinct from `apply-force-concentration`:** apply-force-concentration addresses directing maximum resources to a single decisive point. It does not involve the harvest-and-redirect cycle, and it does not require identifying surplus. They can complement each other: concentrate at the decisive point, and use surplus reallocation to fund that concentration.

**Adopted by:** Boston Consulting Group (BCG matrix, used by McKinsey, BCG, Bain, and Fortune 500 strategy processes globally since 1970); Toyota (heijunka production leveling — core pillar of the Toyota Production System); Amazon (surplus engineering capacity from retail funded AWS; documented in Bezos shareholder letters 1997–2021); Google (Google Ads surplus funded YouTube, Android, Google Cloud, Waymo, DeepMind); Vanguard, Fidelity, and BlackRock (systematic portfolio rebalancing as institutional standard).

**Impact:** Vanguard Research (2019) demonstrated that systematic rebalancing to target allocations outperforms over-concentration in winners over 10+ year horizons by capturing mean-reversion premium; Toyota's heijunka-enabled production leveling achieved 1/10th the defect rate and 1/3rd the inventory of American automakers by the 1980s; Amazon's surplus-reallocation from retail to AWS created a $90B+ revenue business that became the most profitable segment in the company, funded without external capital by harvesting surplus from mature operations.

## Steps

1. **Map the portfolio and define optimal levels for each area.** List all current areas of investment: products, teams, initiatives, markets, asset classes. For each, define the optimal level — the investment level that maximizes return per unit of resource at current conditions. This may be: maintain share at current level (mature product), hit growth targets (scaling product), or minimum viable presence (exploratory bet). Without an explicit optimal level, surplus and deficit have no meaning.

2. **Identify areas running above optimal (surplus).** An area runs surplus when: marginal return on additional investment is declining; the area exceeds its target allocation; further investment produces maintenance of position rather than meaningful improvement; resources would produce higher returns if deployed elsewhere. Common surplus signals:
   - Revenue growing but at slower rate than investment
   - Market share at ceiling with further investment producing diminishing returns
   - Engineering team size exceeds what the product roadmap requires
   - Asset class exceeds target portfolio weight
   - Inventory above demand forecast

3. **Identify areas running below optimal (deficit).** An area runs deficit when: high-return opportunities exist that are resource-constrained; the area has the highest forward expected return per unit of investment but is under-resourced; it cannot execute its roadmap due to resource gaps. Common deficit signals:
   - Growth initiative blocked on headcount or capital
   - New market opportunity identified but unfunded
   - Asset class below target portfolio weight with strong forward return
   - Production line running below capacity with demand backlog

4. **Quantify the surplus and calculate the redirect.** For surplus areas: how much above optimal are they? What is the harvest rate — the rate at which resources can be extracted without degrading the area below its optimal level? Do not extract below optimal. For deficit areas: what level of resource would close the gap to optimal? Prioritize deficits by forward return per unit of resource.

5. **Design the reallocation mechanism.** Reallocation is not announcement — it requires a structural mechanism that enforces the redirect over time:
   - **Capital:** Modify budget allocation process to cap reinvestment in surplus areas and create explicit funding pools for deficit areas
   - **Headcount:** Establish hiring/transfer rules that gate headcount in surplus areas and open headcount in deficit areas
   - **Attention:** Restructure review cycles so surplus areas operate with less senior attention (maintenance mode), freeing leadership bandwidth for deficit areas
   - **Inventory/capacity:** Adjust ordering, production, or capacity planning to bring areas to optimal level

6. **Set the rebalancing trigger.** Define the conditions under which reallocation is reviewed and executed. Options:
   - **Calendar-based:** Quarterly or annual portfolio review compares all areas to optimal levels and triggers reallocation
   - **Threshold-based:** When an area exceeds its target by X%, reallocation is triggered automatically
   - **Event-based:** New market entry, competitive change, or product milestone triggers reassessment
   
   Calendar-based is more reliable for most organizations; threshold-based is more responsive but requires real-time measurement.

7. **Execute and track reallocation effects.** Implement the redirect. Monitor both the surplus area (does it maintain optimal level after harvest?) and the deficit area (does the infusion improve its trajectory?). Reallocation that damages the surplus area without improving the deficit area indicates a wrong diagnosis — re-examine the optimal level definition.

## Rules

- **Never extract below optimal.** The goal is to harvest surplus, not damage the source. A cash cow that is over-harvested declines below its sustainable level. Define and respect the floor.
- **Deficit priority is forward return, not severity of deficit.** The largest deficit is not necessarily the highest priority for reallocation. Direct surplus to the deficit with highest expected return per unit of resource.
- **Reallocation requires a structural mechanism, not willpower.** Announcing that resources should shift is not reallocation. Build the budget, headcount, or process mechanism that enforces the redirect automatically. Human default is to re-accumulate into winners; the mechanism prevents that default.
- **The human default — pile more into winners — is a strong pull.** Stakeholders in surplus areas will resist harvest. Leaders of deficit areas may not advocate effectively for themselves. The rebalancing policy must be explicit, visible, and institutionally enforced to survive political pressure.
- **Apply at regular intervals, not once.** Portfolio areas drift continuously. A one-time rebalancing is not surplus reallocation — it is a restructuring. The principle applies as ongoing policy, revisited at the defined trigger interval.

## Examples

**Product portfolio:** A software company has three products: a mature CRM product (60% of revenue, flat growth, high margins), a growing analytics product (30% of revenue, 40% YoY growth, investment-hungry), and an AI feature (10% of revenue, early stage). The CRM team has 40 engineers but the roadmap only requires 30 to maintain. Analytics needs 20 engineers but has 12. Surplus reallocation: transfer 10 engineers from CRM (surplus: above optimal by 10) to analytics (deficit: below optimal by 8) with 2 allocated to AI. CRM maintains market position; analytics accelerates growth trajectory.

**Capital allocation:** A conglomerate has three divisions. Division A (industrial goods): 25% ROE, $500M invested, mature market — optimal investment level $400M at current growth rate. Division B (software services): 45% ROE, $200M invested, high growth — optimal investment $350M. Division C (consumer goods): 12% ROE, $300M invested — surplus relative to returns. Reallocation: reduce Division C to $200M (-$100M), reduce Division A reinvestment to $400M (free up $100M over 3 years), redirect $200M total to Division B.

**Engineering investment:** A company's authentication service is fully built: 99.99% uptime, no feature roadmap, 8 engineers maintaining it. Optimal level for a mature internal service: 2–3 engineers. The new data pipeline team needs 6 engineers and has 3. Surplus reallocation: transition 5 engineers from auth (surplus: 5 above optimal) to data pipeline (deficit: 3 below optimal). Auth maintains SLA; data pipeline can execute its roadmap.

**Personal attention portfolio:** An executive spends 60% of weekly time on a mature business unit (highest revenue, lowest growth) and 15% on two early-stage initiatives with the highest forward potential. Optimal distribution given forward return: 30% mature unit (sufficient for governance), 35% each for early-stage. Reallocation: reduce mature unit review cadence (monthly vs. weekly), add standing weekly deep-dives with early-stage teams.

## Common Mistakes

- **Harvesting past optimal:** Taking too much from the surplus area, degrading it below its optimal level. The source area becomes a new deficit, and the reallocation produces net harm. Define the floor before harvesting.
- **Directing surplus to the wrong deficit:** Reallocating to the most visible deficit rather than the highest-return deficit. Political pressure, squeaky-wheel dynamics, and emotional attachment bias allocation toward visible distress rather than forward opportunity.
- **One-time reallocation without a recurring mechanism:** Executing a reallocation once and treating it as complete. Portfolio drift is continuous; rebalancing must be a repeating process, not a one-time restructuring.
- **Confusing reallocation with austerity:** Surplus reallocation is not budget cutting. It is optimization — maintaining surplus areas at their optimal level and directing the excess to higher-return uses. Framing it as "taking resources away" misses the point and creates unnecessary resistance.
- **Measuring surplus by absolute performance instead of relative to optimal:** A business unit growing 10% YoY may still be surplus if the optimal investment level is lower than current allocation. A unit declining 5% may be deficit if it has the highest forward return per unit of additional investment. Measure against the optimum, not the absolute performance level.
