Technical Debt as Organizational Debt

Conway's Law tells us that organizations design systems that mirror their communication structures. But there's a corollary that's harder to accept: the technical debt in your systems directly reflects the organizational debt in your teams.

The Mirror Effect

When I was modernizing the 60+ websites at BNY Mellon, the technical challenges weren't random—they mapped perfectly to organizational boundaries. The Investment Management sites had different component libraries than Wealth Management. Pershing had its own deployment process. Each business unit's technical debt told the story of their organizational isolation.

The fragmented codebases weren't just a technology problem—they were symptoms of fragmented communication, unclear ownership boundaries, and competing priorities across business units. Every duplicated component was evidence of teams who didn't talk to each other. Every inconsistent API was proof of missing coordination.

Debt Accumulates at Handoff Points

At Deutsche Bank, the messiest code lived exactly where organizational handoffs happened. The risk calculation engine that touched both front office trading and back office operations? Spaghetti. The reconciliation platform that spanned multiple business lines? Technical debt fortress.

This isn't coincidence. When responsibility for a system spans organizational boundaries, nobody fully owns its quality. Team A builds what they need for their use case. Team B adds their requirements without understanding A's context. Team C makes a "quick fix" that breaks A's assumptions.

The system becomes a fossil record of every organizational misalignment.

The Compound Interest Problem

Technical debt and organizational debt compound each other. Poor code makes it harder for teams to collaborate, which leads to more siloed development, which produces worse code. At Morgan Stanley, I watched this cycle slow down entire platform initiatives.

When teams can't easily integrate with existing systems, they build around them. When they can't understand legacy code, they reimplement instead of refactor. When they can't coordinate deployments, they create separate deployment pipelines.

Each workaround creates more organizational complexity, which generates more technical workarounds.

Breaking the Cycle

The solution isn't just better code—it's better organizational design. When we unified BNY's web platform under Adobe Experience Manager, the technical unification was the easy part. The hard part was creating shared ownership models, cross-team communication rhythms, and unified success metrics.

Some principles that worked:

Platform Teams Over Shared Services: Instead of central teams that build components for others, create platform teams that enable other teams to build their own components within shared frameworks.

Conway's Law as Design Tool: Explicitly design your team structure to produce the system architecture you want. If you want microservices, organize around service boundaries. If you want unified platforms, organize around platform capabilities.

Make Communication Debt Visible: Track cross-team dependencies, handoff delays, and coordination overhead as explicitly as you track technical metrics. If teams are spending more time in alignment meetings than building, your organizational design is broken.

The Leadership Imperative

As engineering leaders, we can't solve technical debt without addressing its organizational roots. Refactoring code without refactoring team structures just creates tomorrow's technical debt.

The teams that consistently ship clean, maintainable systems aren't just technically excellent—they're organizationally coherent. They have clear ownership boundaries, effective communication patterns, and shared understanding of their platform's purpose.

Your system's architecture is a mirror of your organization's health. If you don't like what you see in the code, look at the org chart.

The most important architectural decisions happen in organizational design, not system design. Get the teams right, and the systems follow. Get the teams wrong, and no amount of refactoring will save you.
