Are You Still Dependent on Legacy Thinking?

*Written by Marc Boudria, Chief Innovation Officer at BetterEngineer

It’s startling how many organizations,  even some of the world’s most recognized brands, continue to operate as if it were still 1997. The systems they rely on, the way they think about technology, and the cultural blockers embedded deep within their walls all point to one dangerous truth: legacy thinking is alive and well.  

It shows up everywhere:

• In rigid approval chains that can’t keep pace with modern product cycles.
• In proprietary, custom-built tools that no longer serve the business but persist simply because “that’s how we’ve always done it.”
• In shallow investments in internal systems that prop up misery: employees stuck using outdated tools that make their days harder, with decision makers scoffing, “Well, what’s the ROI on fixing that?”
  

This mindset is more than just old-fashioned. It’s actively harmful. Legacy thinking is a pox on innovation. It’s the root cause of the fragmented, siloed, and poorly integrated tech stacks we see everywhere today. It’s why your data can’t flow freely across teams. It’s why simple tasks take twice as long. It’s why your best people quietly dread Mondays.

Why Legacy Thinking is So Dangerous

Let’s be clear: it’s not legacy technology that’s the core problem. Plenty of older systems work just fine when properly maintained and integrated into a modern architecture. The real threat is legacy thinking, a mindset that:

• Prioritizes sunk costs over future opportunities
• Confuses comfort with competence
• Believes that technology is only a cost center, not a strategic enabler
• Views employee tooling as an afterthought rather than a productivity multiplier
• Expects new tech to simply drop in and produce magic, without cultural or process change

This thinking shows up in questions like:

• “Why spend money improving an internal tool if we’re still technically getting by?”
  
• “Why unify our data when each department seems to manage fine on their own spreadsheets?”
  
• “Why upgrade our workflow if the old one still sort of works?”
  

The consequences of this approach are massive yet hidden. A recent survey by Salesforce found that 81% of IT leaders say disconnected systems create silos that slow down digital initiatives. Gartner also predicts that through 2027, 75% of organizations will have attempted to modernize legacy applications, yet half will fail because they treat modernization purely as a technical exercise, ignoring cultural and process shifts.

In short, your technology is only as modern as your mindset. If leadership and culture stay stuck in the past, so will your systems, no matter how many cloud migrations or AI pilots you run.

The Human Toll of Legacy Thinking

Legacy thinking doesn’t just impact your systems. It crushes your people.

• Employee frustration: Forced to use slow, clunky internal tools that actively waste hours of their time each week.
• Lost innovation: Smart employees with fresh ideas quietly stop speaking up, because they’ve learned “that’s not how we do things here.”
• Attrition: Top talent leaves for organizations that empower them with modern platforms and genuinely care about making work life better.

And ironically, the very ROI questions that leadership uses to stall improvement become self-defeating. A study by Forrester found that improving employee experience can drive up to a 20% increase in productivity and a 30% increase in retention. Better internal systems pay for themselves many times over,  if only leaders could break free from legacy thinking long enough to see it.

A Path Forward: How to Break Out of Legacy Thinking

Overcoming legacy thinking is not about ripping everything out and starting from scratch. It’s about shifting perspective and creating space for thoughtful, incremental change. Here’s how to begin:

1. Challenge the sunk cost fallacy

Stop letting past investments dictate your future. That $3 million you spent five years ago on a now-awkward custom tool? That’s gone. Holding onto it just because it was expensive compounds the loss. Instead, calculate the opportunity cost of not fixing it.

2. Center on the employee experience

Every outdated workflow or clunky tool is a daily tax on your people. Start treating internal systems like customer-facing products — worthy of real design, iteration, and delight. Ask your employees what slows them down and frustrates them. Then actually act on it.

3. Pilot modern approaches in safe spaces

Big-bang transformations often fail. Instead, choose a specific area to modernize with clear outcomes. Run short experiments (like 30-day sprints) that demonstrate value. Use these wins to build momentum and internal champions.

4. Break the proprietary mindset

Stop reinventing wheels internally when robust platforms, integrations, and APIs exist. Embrace openness and interoperability. Favor platforms that evolve and scale with you over brittle, custom-built monoliths.

5. Align incentives with change

Tie modernization goals to personal and departmental incentives. If your leaders get bonuses for “cost-cutting,” they’ll keep deferring upgrades. If they’re rewarded for employee productivity or customer satisfaction, behavior shifts.

6. Adopt continuous learning

Create a culture where it’s normal to test new tools, attend conferences, run hackathons, and question old assumptions. When your workforce is constantly learning, legacy thinking has less space to fester.

Quick Diagnostic: Are You Stuck in Legacy Thinking?

Answer yes or no to these:

1. Do you still use internal tools that your employees openly dislike, because “it’s not worth fixing”?
2. When someone proposes an improvement, is your first question “What’s the ROI?” instead of “How does this make work better for our people or customers?”
3. Do teams rely on disconnected spreadsheets or manual data handoffs because integrating systems feels too big to tackle?
4. Have you kept a custom tool alive mainly because “we already spent so much on it”?
5. Is experimentation viewed as risky or wasteful instead of essential to learning?

3 or more YES answers?

You’re likely running on legacy thinking and paying for it every day in hidden costs, lost productivity, and frustrated talent.

Don’t Let Legacy Thinking Be Your Competitive Moat In Reverse

The world has moved on. If your organization is still asking 1997 questions, you’ll keep getting 1997 outcomes. Meanwhile, competitors with modern mindsets will be deploying AI responsibly, automating the right processes, and empowering their employees to do meaningful work.

The truth? Legacy thinking is often the only real moat protecting your competitors, because it’s holding you back.
