Software development and product management are disciplines built on iteration, testing, and resilience. They thrive on cycles of design, review, and improvement. Business continuity shares the same goals — ensuring systems and people can withstand disruption — but often struggles with similar pitfalls. By examining practices from software, we can sharpen how organisations prepare for disruption, and highlight the value of trusted external partners in creating environments where failure is not a risk, but a learning opportunity.
Segregation of Duties
In software, developers do not test their own code. Independent QA ensures objectivity and reduces blind spots. In BC, however, professionals often both write the plan and exercise it, which risks internal bias. Even when testing is segregated, there is still an element of marking your own homework — testers know the organisation too well, and expectations shape outcomes.
Build independent review loops into continuity planning. External partners can facilitate exercises that challenge assumptions, ensuring plans are tested from fresh perspectives rather than confirmed by familiar ones.
Disaster Recovery: Simpler is Better
In technology, disaster recovery is most effective when failover and recovery are simple, repeatable, and well-rehearsed. Reluctance to trigger DR often stems from complexity — if recovery feels fragile, leaders hesitate. The same applies in BC: hesitation to act can cost precious time.
Case Study: Cayman Earthquake
During an earthquake in the Cayman Islands, our team had a proven failover process that could have been triggered quickly. Decision authority, however, was split between two people. One leader hesitated because of a prior, unrelated experience with a slow document migration — that memory created reluctance even though the failover itself was simple and tested. By the time any consensus might have been reached, the window for decisive action had passed. Fortunately it proved unnecessary on that occasion.
This episode illustrates three distinct lessons. First, full-scenario exercising incorporating the entire DR cycle is essential to build confidence. Second, decision-making authority must be clear and actionable in real time — too many moving parts in the decision tree dampen response. And third, it underscores the difference between expected and unexpected threats. Hurricanes were an expectation in Cayman: even rapid development provides hours to confer and make collective decisions. Earthquakes, by contrast, arrive without warning and demand action in seconds. Continuity planning often prepares us well for the most likely scenarios, but it is the unexpected shocks — those that come with no time to confer — that trip organisations up.
"We prepare well for the expected. It is the unexpected — with seconds to react — that trips us up."
Testing and Verification
Even simple DR mechanisms fail if they are not tested. In BC, hesitation to act often comes from uncertainty: will this actually work? Decision-makers want proof before committing.
Regular, verified exercises build confidence. Testing is not about proving perfection — it is about uncovering weaknesses and strengthening resilience. Failure in an exercise is not a setback; it is the most valuable outcome, because it reveals what needs to be refined.
Continuous Improvement: Bugs and Features
In product management, unresolved bugs or feature requests get forgotten. In BC, identified improvements often languish unimplemented.
Treat BC gaps like bug tickets — log them, prioritise them, and resolve them quickly, then re-test. Maintaining this discipline ensures improvements are acted upon rather than lost in the noise of daily operations.
Version Control
Software thrives on version control: every change is tracked, rolled back if needed, and documented. BC plans often lack this discipline, leading to confusion over which version is current.
Adopt version control principles for BC documentation — clear numbering, changelogs, and rollback options. Structured frameworks ensure organisations always know which plan is live and what changed between versions.
Managing Third-Party Dependencies
Software projects can stall when over-reliant on external libraries or vendors. BC plans can fail if they depend too heavily on third parties without clear risk management. This is especially true in cloud environments, where teams often assume the vendor handles DR and stop short of fully verifying those assumptions.
Cloud providers offer resilient platforms, but resilience in the platform is not the same as validated recovery for your service, data, or operational processes. Vendor SLAs and built-in redundancy are important, yet they do not replace the need to verify end-to-end recovery, revalidate failover procedures after changes, or exercise the human and integration points that sit outside the provider's responsibility.
Map dependencies, test vendor responses, and revalidate recovery repeatedly. Include vendors in exercises where possible, and run scenarios that simulate vendor degradation or misconfiguration. Vendor assumptions should be proven rather than presumed.
Conclusion
Software development and product management show us that resilience is not just about having a plan — it is about testing, simplifying, iterating, and managing dependencies. Business continuity can borrow these lessons to move beyond static documents, becoming a living system of preparedness and confidence.
The Cayman earthquake experience illustrates the stakes: hesitation can arise from technical complexity, prior scars, fragmented authority, or simply the shock of an unexpected event. By building the response, testing and re-testing it, and then giving clear authority and support to trigger that response as a precaution rather than waiting for absolutes, organisations can act decisively when seconds matter.
"Authority must empower precautionary action — not wait for absolute certainty."
