Key takeaways
- A business impact analysis (BIA) identifies which people, systems, and locations matter most when disruption hits.
- This workbook covers People, System, and Location tabs with impact-over-time scoring and RTO targets.
- Output feeds directly into your BCP/DR plan.
- SecureSlate helps connect BIA outputs to controls and audit evidence.
Overview
A BIA answers: if a critical system or team is unavailable, what breaks, how fast does impact escalate, and what do we restore first? It is a core input to business continuity planning and a common request in SOC 2 and ISO 27001 audits.
What makes it useful
- Five structured tabs: Cover, People, System, Location, and Impact Level Definitions.
- Impact over time: Score Low through Catastrophic at 0 to 1 days, 2 to 4 days, 5 to 10 days, and 10+ days.
- RTO and MTPoD: Set recovery targets per system and location.
- Contingency column: Document the actual failover or workaround for each dependency.

Tab-by-tab walkthrough
BIA Cover
Organization name, version, date, BCMS owner, classification, and review cycle.
Impact Level Definitions
Calibrate Low, Medium, High, and Catastrophic tiers. Adjust financial thresholds and guidance to match your business.
People
List departments with priority, head of function, staffing levels, work location, impact over time, and system dependencies.
System
For each system: what it does, who uses it, RTO, MTPoD, impact over time, people dependencies, and contingency plan. Include production app, auth, database, and key SaaS tools.
Location
Offices, hosting sites, and cloud regions with the same RTO, MTPoD, and impact columns as systems.
How to use it as audit evidence
| Evidence type | Template tab |
|---|---|
| Business impact methodology | Impact Level Definitions |
| Critical functions identified | People |
| Recovery priorities | System RTO/MTPoD columns |
| Site dependencies | Location |
| Management review | BIA Cover version and date |
Review annually or after major architecture, vendor, or org changes.
Common mistakes
- One generic "IT platform" row instead of separate critical services
- RTO targets set without testing actual recovery time
- Contingency column left blank
- BIA completed once and never updated
How SecureSlate helps
SecureSlate connects BIA outputs to continuity controls, evidence refresh, and audit-ready exports.
FAQ
How is a BIA different from a BCP/DR plan?
The BIA identifies impact and priorities. The BCP/DR plan documents how you recover. Use both templates together.
Who should run the BIA workshop?
Typically security or operations, with system owners from engineering and business units.
Is a BIA required for SOC 2?
Not always as a named document, but it commonly supports availability and continuity expectations.
