Technology Debt

Technology Debt

Your tech stack gets more expensive every month you delay tough decisions.

Last week, a CIO showed me his new problem: a 20-year-old ERP system running critical processes for a $400M manufacturer. No documentation. No original developers. Every update made everyone nervous. "It works," he said, "until it doesn't."

His predecessor avoided the modernization question for seven years. Every budget cycle, the team proposed upgrades. Every time, leadership said they were too expensive and risky. Now, they spend triple on maintenance compared to what they would have paid for modernization.

Technical debt builds because we keep choosing short-term operations over long-term strategy.

The real cost lies in the widening gap between what your business needs and what your systems can handle. I've watched companies miss market opportunities because their systems couldn't adapt fast enough. Others lose good IT staff who refuse to babysit outdated systems while their skills become obsolete.

Here's how to address this:

  1. Make technology debt visible. Provide your CFO with actual figures on maintenance costs, lost opportunities, security risks, and productivity impacts.
  2. Create parallel paths. Keep critical legacy systems running while building new capabilities alongside them.
  3. Segment and prioritize. Not everything needs upgrading at once. Focus first on the parts of your stack with the most strategic value or highest risk.
  4. Build capability bridges. Use APIs and integration layers so that new systems can gradually replace functions from legacy systems, reducing transition risks.

Companies that handle tech debt well don't necessarily have massive IT budgets. What they do have are leaders who face reality and make the hard calls, refusing to kick problems down the road.

Every quarter you put off these decisions actively increases your technology debt. The interest compounds, and eventually, someone pays the bill.

I help leadership teams tackle these technology transition decisions. If you're seeing growing tech debt in your organization and want to discuss practical approaches, reply to this email. I've got a few frameworks that might help.

This article hits home—especially the part about compounding tech debt. While bold moves are ideal, sometimes steady, incremental progress is the most realistic path forward. In many organizations, slow change isn’t a lack of vision—it’s a deliberate step toward modernization. It’s better to start moving than to keep standing still.
