David Etue is Chief Executive Officer of Cyberbit and a Senior Fellow at the National Security Institute’s Cyber and Technology Center.gettyWhen a serious cyber incident hits, the first thing that breaks is rarely the playbook. It is the assumption that the playbook alone was enough.In a real attack, teams face imperfect information, conflicting priorities and pressure to make decisions. That is when hidden weaknesses in communication, chain of command and cross-functional trust become visible. Organizations do not rise to the level of their documentation; they fall to the level of their practiced coordination.Incident Response Is A Performance DisciplineMost organizations have invested heavily in incident response on paper. They can point to detailed runbooks, escalation paths, RACI charts, certified analysts, multiple tools and polished dashboards.All of that is necessary, but attackers do not follow your documentation, and they are not obligated to follow your swim lanes. They probe the seams between teams, the gaps in decision rights, the assumptions about who will step up when the pressure is real.This is why incident response should be treated as an organizational performance discipline, not simply a security operations process. The strongest teams are not always the ones with the most sophisticated technology stack; they are the ones that have built the habits to communicate crisply, escalate decisively and adapt in real time. In live incidents, leaders quickly discover whether their teams can maintain role clarity while still flexing to cover gaps, or whether confusion over ownership and authority slows them down when time matters most.A License Is Not ReadinessThe driving analogy is useful here. A teenager can pass driver’s education, memorize the rules of the road and ace the written test. They technically have a license. But no reasonable parent mistakes that for true readiness to handle rush-hour traffic in a thunderstorm.Real readiness comes from time behind the wheel, merging into fast-moving lanes, reacting to other drivers’ mistakes and making good decisions when conditions are less than ideal. And driving is just one person (and maybe some passengers). Incident response isn’t just a person; it’s a team. Playbooks, certifications and tools drive knowledge and skills, but experience and realistic drills are the miles that build judgment and confidence.High-Performing Teams Differentiate ThemselvesResearch on high-performing IT teams reinforces this human-first view of performance. Gene Kim’s multiyear work on elite technology organizations shows that culture, trust and disciplined execution under pressure separate top performers from the rest. In his studies, he found that the best performers combine strong process discipline with the ability to quickly sense, decide and adapt when conditions change. That's exactly the mindset incident response leaders need when an incident veers off script from the playbook.Cybersecurity leaders who understand this distinction shift their focus from “Do we have a plan?” to “How does our organization actually behave under pressure?”They invest in cyber ranges, realistic crisis simulations and frequent drills. This equips the team with real experience under pressure and reveals whether leaders can process ambiguous information, whether communications stay aligned as the situation evolves and whether decisions are made at the right level with appropriate speed.Realistic Practice Builds Confidence Under PressureRealistic rehearsals also reduce psychological stress. When team members know they have practiced difficult scenarios in a safe environment, they build confidence that carries into real incidents. They have already seen what it feels like when tooling lags, when new indicators emerge mid-incident or when leadership asks for business impact assessments before the technical picture is complete. That familiarity makes it far more likely they will execute the playbook intelligently rather than freeze or improvise in unproductive ways.Navigating the path forward, technology and security leaders should hold off the writing of yet another playbook and rather focus on deliberately building the capability to execute that playbook, and—most importantly—adapt it under real-world conditions.That requires time, sponsorship and a willingness to expose inconvenient truths about how the organization currently performs.Actions You Can Take To Build Durable ReadinessTake these three actions for quality preparation:1. Rehearse incidents often enough that critical decisions are familiar before they are urgent.Move from annual, scripted tabletop exercises to frequent, realistic simulations that use actual tools, data flows and escalation paths. Treat these as serious events with measurable objectives, not as compliance checkboxes.2. Test the whole system, not just the SOC.Design scenarios that pull in IT, legal, communications, business owners and executives, because attackers exploit seams between teams, not organizational charts. Use these exercises to clarify who decides what, when and based on which inputs, then adjust roles and authorities where you see friction or delay.3. Define success by behavior under pressure, and turn every exercise into an improvement engine.Measure decision speed, communication quality, role clarity and recovery outcomes alongside technical containment metrics. Run structured retrospectives after each exercise or real incident, then update playbooks, permissions and governance based on observed behavior, not on how you hope the organization will respond next time.At the end of the day, everyone has a playbook. The question is whether your teams have driven enough miles, in enough conditions, that you are comfortable handing them the keys when the storm inevitably hits.Forbes Technology Council is an invitation-only community for world-class CIOs, CTOs and technology executives.
