Deep Dive into Net Present Value (NPV): Part 5 - Stacking Decisions

"Too many cooks spoil the broth."— Proverb

When businesses make decisions, they often focus on the net present value (NPV) of each individual choice. While this approach ensures that every decision appears sound on its own, it can overlook the bigger picture: how decisions interact with one another. This is where a holistic view becomes critical. Even decisions that are individually positive can collectively lead to problems when they stack in ways that were not anticipated.

Understanding the Domino Effect of Decisions

Each business decision, no matter how well-justified, contributes to a larger strategy. Using NPV methods usually assumes that the individual decisions are uncorrelated with each other, because NPV embeds assumptions about overall risk into its framework. When decisions conflict, rely too heavily on the same resources, or compound risks, they can create unintended challenges. The sum of 5 individual NPV positive decisions could well be negative.

Shared Resources: A Hidden Bottleneck

Multiple decisions can unintentionally place excessive demands on shared resources. For instance, expanding marketing efforts and launching a new product might seem like complementary initiatives. But if both rely heavily on the same internal teams or external vendors, those resources may become overstretched. This strain can lead to missed deadlines, reduced quality, and long-term inefficiencies that erode the expected gains from both efforts.

Conflicting Goals: When Initiatives Clash

Some decisions may seem logical in isolation but undermine each other in practice. Imagine scheduling a major promotional campaign while also closing locations for renovations. The sale might drive additional traffic to stores, but construction could make the shopping experience chaotic or uninviting. These opposing goals cancel out the benefits of each initiative, leaving your business in a worse position than if either had been pursued alone.

Compounded Risks: The Snowball Effect

Risk often appears manageable in a single decision but grows exponentially when similar risks are repeated across multiple initiatives. For example, targeting a new customer demographic can be a smart way to grow your business. However, if all your marketing, product development, and operational adjustments are directed at that same demographic, the risks associated with that customer base become magnified. A single failure—whether due to misjudging the market or external factors—can have far-reaching consequences.

Cash Flow Strain: Overlapping Financial Demands

Stacked decisions can reshape your cash flow in unexpected ways. Multiple initiatives might plan for temporary dips in revenue or increased spending, assuming that cash reserves will fill the gaps. However, when these dips align, they can create a significant cash flow crunch. This risk is especially pronounced for smaller businesses, where even short-term liquidity issues can have serious implications.

Building a Holistic Decision Framework

To ensure that decisions complement rather than conflict, businesses must adopt a more integrated approach to planning:

1. Map Out Dependencies: Identify shared resources and evaluate how decisions will collectively impact their availability. Ensure workloads are balanced and realistic.

2. Evaluate Interactions: Analyze how decisions align with or oppose one another. Look for potential conflicts in timing, objectives, or resource requirements.

3. Diversify Risks: Spread efforts across different customer segments, product lines, or initiatives. Avoid placing all bets on a single strategy to mitigate vulnerability.

4. Monitor Financial Overlaps: Consolidate cash flow projections for all major decisions. Stress-test scenarios to ensure financial stability under different conditions.

5. Revisit and Adjust: Regularly review decisions as conditions evolve. Flexibility allows businesses to pivot when interactions between initiatives reveal unforeseen challenges.

Conclusion

NPV is an invaluable tool for evaluating individual decisions, but it's true power lies in the broader context of strategy. By viewing decisions holistically and understanding how they stack, businesses can better anticipate challenges, allocate resources effectively, and maintain financial stability. Ultimately, the goal is not just to make good decisions, but to ensure that those decisions work together to create sustainable growth and success.
