Spreadsheets and paper create risk because they are reporting tools, not business systems. They can help collect information, but they do not provide durable controls for validation, workflow, or end-to-end visibility. As volumes grow, teams lose accuracy, speed, and auditability, which makes complex insurance processes harder to manage consistently and safely.
Why spreadsheets and paper become a control problem as insurance workflows grow
Spreadsheets and paper are workable for small, low-velocity tasks because people can compensate manually for gaps. In insurance workflows, that breaks down once the process depends on consistent handoffs, approvals, evidence retention, or policy-driven exceptions. The operational risk is not just error, it is the loss of a dependable system of record that can enforce rules and show what happened.
That matters because insurance operations are rarely a single transaction. A claim, policy change, underwriting referral, renewal, or endorsement often moves across multiple people and checks. When the workflow lives in files and forms instead of a controlled system, each handoff becomes a chance for delay, duplication, missing fields, or silent divergence between versions.
Where the risk shows up in day-to-day insurance operations
The most common failure mode is not dramatic system outage, but accumulated process drift. One spreadsheet may contain the latest customer details while another contains the underwriting decision, and a paper file may hold the signed approval that never makes it back into the working record. That creates a fragmented process where teams can no longer rely on one trusted view of the case.
Operationally, this affects accuracy, speed, and auditability at the same time. Errors are easier to introduce and harder to detect, cycle times extend because people wait on email or manual review, and managers lose the ability to prove whether a rule was followed. Once volume increases, those weaknesses scale with the workload rather than being absorbed by the process.
Why this weakens resilience, governance, and audit readiness
Paper and spreadsheets also make it harder to apply durable controls. Validation becomes inconsistent, access is harder to govern, version control is fragile, and exceptions can be approved without a reliable trail. That means the process may still function, but it does so through human memory and local workarounds instead of repeatable controls that can survive staff changes and high throughput.
For insurers, the deeper issue is governance. A workflow that cannot show who changed what, when, and why is difficult to supervise, difficult to remediate, and difficult to defend in an audit or dispute. This is why operational risk in insurance is often about control fragility, not merely administrative inconvenience. For broader control design, teams often anchor this thinking in NIST Cybersecurity Framework 2.0 and NIST SP 800-53 Rev 5 Security and Privacy Controls, especially where auditability and access control matter.
Risk and Threat Considerations
When insurance operations depend on spreadsheets and paper, the main risk is control collapse through fragmentation. A malformed formula, an overwritten tab, a lost attachment, or an unsigned paper step can all create a process gap that is invisible until a claim is disputed, a deadline is missed, or an exception is discovered too late.
Failure mechanism: The workflow loses integrity because key decisions, validations, and approvals are scattered across uncontrolled artifacts, so the organisation cannot reliably reconcile the authoritative state of a policy, claim, or underwriting case.
Impact: The business sees rework, slower turnaround, higher error rates, weaker customer outcomes, and an audit trail that may be incomplete or inconsistent when it is needed most.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.OV-01 — Oversight of Cybersecurity Risk | Insurance workflows need oversight of process integrity and auditability. |
| Recommendation — Establish oversight for workflow integrity, exception handling, and evidence retention. | ||
| NIST SP 800-53 Rev 5 | AU-2 — Event Logging | The question centers on loss of audit trail and traceability in manual workflows. |
| AC-6 — Least Privilege | Manual spreadsheets and paper weaken access discipline and separation of duties. | |
| Recommendation — Log key workflow actions so claims and policy changes remain traceable. Limit who can alter sensitive workflow records and supporting evidence. | ||
| ISO/IEC 27001:2022 | A.5.37 — Documented operating procedures | Paper and spreadsheet processes rely on controlled procedures and repeatability. |
| Recommendation — Document the procedure and keep the operational record under version control. | ||
| CIS Controls v8 | CIS-5 — Account Management | Operational workflows depend on accountable ownership and controlled access. |
| Recommendation — Assign accountable owners for each workflow stage and review access regularly. | ||
Practitioner Guidance
What to verify: Confirm whether the process has a single authoritative record, defined ownership for each handoff, and a reliable way to trace exceptions end to end. If any of those depend on someone manually copying data between files, the workflow is already carrying avoidable operational risk.
What good looks like: The process should preserve version history, approval evidence, and decision rationale without relying on individual memory or local file discipline. For insurers, that means the workflow can be reviewed and resumed by another operator without guessing which spreadsheet or paper copy is current.
Practitioner takeaway: Spreadsheets and paper are acceptable inputs, but they are weak operating platforms for insurance once control, traceability, and scale become important.
