It’s 2:47 a.m. The payment processing service is down. Your phone rings and you already know who it’s going to be — Alex. Because it’s always Alex.

Alex knows that system cold. Alex wrote most of it, fixed the last three outages, and has never once complained about being woken up. Your CTO loves Alex. Your team admires Alex. And here’s the uncomfortable truth: Alex is one of your biggest operational risks.

If you’re a new IT leader, the hero culture in IT is probably already present on your team. You just haven’t seen it as a problem yet. This article will change that.

What Is Hero Culture in IT?

Hero culture in IT is an organizational pattern where a small number of individuals — sometimes just one — become the irreplaceable go-to for critical systems, incidents, or decisions. These individuals are rewarded (explicitly or implicitly) for their heroics: staying late, solving crises solo, being the only one who “really gets it.”

It feels like high performance. It isn’t. It’s a reliability problem wearing a performance costume.

The risk has a formal name: single point of failure (SPOF). In system architecture, a SPOF is any component whose failure brings down the whole system. In team design, your “Alex” is that component.

There’s also a related concept worth knowing: the bus factor (sometimes called the truck factor). Ask yourself: if a key person were hit by a bus tomorrow — or quit, got sick, or took a vacation — how many of your systems or processes would become unmanageable? A bus factor of one means the answer is “a lot.” That’s not a team. That’s a liability.

How Leaders Accidentally Reward Hero Culture

New managers don’t create hero culture on purpose. They inherit it, and then they feed it without realizing it. Here’s how:

Rewarding availability over systems. When you praise someone for being on-call 24/7 or for “always being there,” you’re signaling that individual heroics matter more than team resilience. Others learn to replicate the behavior.

Deferring documentation. When the team is behind and a deadline is looming, documentation gets cut. Runbooks don’t get written. That tribal knowledge stays locked in Alex’s head — and the next incident proves it.

Promoting based on crisis performance. Performance reviews that celebrate “saved the day” moments without asking why those moments were necessary reward the symptom, not the system. A well-run team has fewer crises, not more heroic recoveries.

Under-investing in cross-training. If only one person understands a critical system, that wasn’t an accident — it was a series of decisions to never pair, rotate, or document.

The Real Costs You’re Not Tracking

The visible cost of hero culture is easy to miss because everything seems to be working. The hidden costs accumulate until something breaks.

Knowledge silos. When one person holds all the context on a system, every decision, incident, and change runs through them. Velocity slows. Bottlenecks appear. “We need to wait for Alex” becomes a team mantra.

Documentation debt. Missing runbooks, undocumented architecture decisions, and “just ask me” workflows are the financial debt equivalent for operations. The interest compounds until a recovery that should take 20 minutes takes four hours because nobody wrote anything down. The Google SRE Book has a practical framework for runbook development and operational documentation — it’s free and worth assigning to your team leads.

Burnout as a false signal. When Alex consistently works nights and weekends and always delivers, burnout doesn’t look like failure — it looks like dedication. Until Alex quits. Or makes a $200,000 mistake at 3 a.m. because they’re exhausted. Research from organizations like the World Health Organization classifies burnout as an occupational phenomenon with measurable impacts on judgment and performance. Fatigue is not a feature.

Brittle incident response. When your on-call rotation is “Alex, and if Alex doesn’t answer, also Alex,” your mean time to recovery (MTTR) is hostage to one person’s availability and health. The AWS Well-Architected Framework treats resilience as a design requirement — the same principle applies to team design.

Diagnostic: Does Your Team Have a Hero Culture Problem?

Run through this checklist honestly. The more boxes you check, the more urgent the conversation.

• One person is consistently first responder on critical incidents
• You have systems or services with no written runbook
• A key person’s vacation causes team anxiety or coverage gaps
• New team members can’t independently resolve common incidents within 90 days
• Post-incident reviews focus on who fixed it, not why it broke
• On-call load is distributed unevenly (one person carries 60%+)
• Documentation is consistently deprioritized in sprint planning
• The phrase “just ask [name]” appears regularly in Slack
• You’re hesitant to reassign or promote your “best” person because of coverage fear

If you checked five or more: you have a structural problem, not a people problem. That distinction matters — because the fix is organizational, not personal.

The 30-60-90 Day Playbook to Break Hero Culture

This isn’t a culture change deck. These are specific actions you can take now.

Days 1–30: Diagnose and Name the Risk

Map your SPOFs. Build a simple grid: list your critical systems or services on one axis, list your team members on the other. Mark who can independently manage each one. Any column with only one check is a SPOF.

Audit your runbooks. A runbook doesn’t need to be a 40-page manual. It needs to answer: what is this service, what does failure look like, what are the first five steps to recover it, and who else needs to know? Track a KPI: % of production services with a tested runbook. Start from zero if you have to — just start.

Have a direct conversation with your heroes. Don’t frame it as “you’re a problem.” Frame it as “I’m trying to make sure you can take a real vacation without your phone going off.” Most burned-out heroes are relieved someone noticed.

Days 31–60: Distribute Knowledge Deliberately

Pair on every major incident. Make it policy: no incident is resolved solo. The secondary responder isn’t there to help — they’re there to learn. Rotate who leads.

Introduce shadow on-call. Before rotating a new person into primary on-call, have them shadow for two weeks. They observe, ask questions, and get hands-on in low-stakes situations.

Start a “knowledge transfer” sprint item. In every sprint or planning cycle, reserve time for documentation. Treat it as technical debt — because it is. Atlassian’s team documentation guidance is a practical starting point for lightweight runbook templates.

Restructure post-incident reviews (PIRs) as blameless learning. The point isn’t who fixed it. The point is what system condition allowed the incident, and what process change prevents the next one. Google’s SRE framework popularized this — ITIL 4 from Axelos formalizes it for broader IT operations.

Days 61–90: Rebuild Incentives and Measure Resilience

Rewrite what you reward. In performance reviews, add these questions: Did this person document what they know? Did they actively develop others? Did they reduce on-call load for the team? Heroics that don’t produce resilience shouldn’t earn top marks. Resilience that doesn’t require heroics should.

Create an on-call health metric. Track incidents per person per month, hours spent in active response, and time-to-close by responder. If the distribution is skewed, the data makes the conversation easier.

Celebrate the boring. When a junior team member resolves an incident independently using a runbook Alex wrote — that’s the win. Recognize it publicly. That’s what sustainable performance looks like.

Common Objections — And How to Respond

“But we’re understaffed. We need Alex to cover everything.” Understaffing makes knowledge silos more dangerous, not less. When Alex burns out or leaves, you go from understaffed to critically understaffed with a system nobody understands. Cross-training is a risk mitigation strategy, not a luxury.

“He likes being the hero. This is how he’s motivated.” That may be true — and it’s a management problem. If your team member’s sense of value depends on being irreplaceable, that’s a psychological dependency tied to your incentive structure. Redirect that motivation toward being the person who builds the team’s capability, not the person who saves it.

“Documentation slows us down.” Runbooks written after the fact don’t slow sprints. They accelerate recovery. A 30-minute runbook can save a 4-hour incident. NIST’s guidance on cybersecurity and operational continuity frames documentation as foundational to resilience — not optional overhead.

“We can fix this after this busy period.” The next busy period is six weeks away. And the one after that. Busy periods are permanent in IT. You fix it during the chaos, not after.

The Takeaway: Sustainable Performance Is the Goal

High-performing IT teams aren’t built on heroes. They’re built on systems, documentation, shared knowledge, and incentives that reward the team’s collective resilience over any individual’s capacity to absorb punishment.

Your best engineer is a huge asset. The goal isn’t to diminish what they know — it’s to make sure that knowledge lives in the team, not just in one person’s head.

Start with the SPOF map. Write one runbook this week. Pair on the next incident. Small moves compound fast.

Alex deserves a full night’s sleep. Your team deserves a system that doesn’t require anyone to be a hero to survive.

6. FAQ

Q: What is hero culture in IT, and why is it a problem? Hero culture in IT is when one or a few individuals become the sole owners of critical knowledge or systems. It’s a problem because it creates single points of failure, drives burnout, and makes teams fragile when those individuals are unavailable.

Q: What is the bus factor and how does it apply to IT teams? The bus factor is the minimum number of team members who, if suddenly unavailable, would halt operations. A bus factor of one means a single departure could cripple your team. IT leaders should aim for a bus factor of at least two on every critical service.

Q: How do I document institutional knowledge without slowing the team down? Start with post-incident runbooks — write them immediately after resolving an incident, while context is fresh. Keep them short: five to ten steps, clear ownership, tested quarterly. This approach doesn’t slow sprints; it accelerates future recovery.

Q: How do I restructure on-call to avoid overloading one person? Map current on-call load per person, identify imbalances, and introduce shadow rotations before making new engineers primary. Use documented runbooks as the prerequisite for primary on-call eligibility.

Q: How should I handle a team member who wants to be the hero? Reframe the recognition model. Publicly reward acts that build team capability — pairing, documentation, mentoring — not just individual fire-fighting. Redirect that motivation toward becoming the person who elevates the team’s collective performance.

Q: What KPIs should I track to measure progress against hero culture? Track: percentage of critical services with tested runbooks, distribution of on-call incidents per person per month, number of engineers who can independently manage each critical service, and average MTTR across on-call rotation members.

Q: Can hero culture exist in small IT teams? Yes — it’s often worse in small teams because there are fewer people to absorb coverage gaps. Small teams need cross-training and documentation more urgently, not less.
