What I Learned Leading Major Incidents in Banking
Five lessons from banking and technology operations on incident response, communication and operational resilience.
When technology fails, organisations often focus on the systems.
In reality, major incidents are rarely just technical problems.
They are communication problems. Governance problems. Decision-making problems.
Having spent over a decade working within banking and technology operations, I've seen first-hand how the most resilient organisations respond differently during times of pressure.
Here are five lessons I've learned.
1. Clear ownership matters more than perfect technology
During a major incident, confusion is expensive.
- Who is leading?
- Who is communicating to stakeholders?
- Who makes decisions?
Organisations that define these responsibilities in advance recover faster and communicate with greater confidence.
A Major Incident Playbook, severity matrix and escalation framework are not "nice to haves"—they are essential.
2. Communication is a control
Many organisations invest heavily in monitoring tools but neglect communication processes.
During an incident, stakeholders need:
- Clear updates
- Consistent messaging
- Realistic timelines
- Transparent ownership
The ability to communicate effectively is a resilience capability.
3. Every incident should strengthen the organisation
Post Incident Reviews (PIRs) are often treated as administrative exercises.
The best organisations use them differently. They ask:
- What failed?
- Why did it fail?
- Which controls were missing?
- How do we reduce the likelihood of recurrence?
The objective isn't blame. It's maturity.
4. Operational resilience starts long before an incident
Resilience is not measured by whether incidents occur. It is measured by:
- How quickly you detect them.
- How effectively you respond.
- How confidently you recover.
Strong governance, clear processes and regular reviews make a significant difference.
5. Technology risk is business risk
Outages affect:
- Customers
- Revenue
- Reputation
- Regulatory obligations
Technology leaders increasingly need to think beyond systems and consider business impact.
The most resilient organisations recognise this and invest accordingly.
