1. Purpose
The Business Impact Analysis (BIA) Template provides a structured method for identifying critical business services, understanding the consequences of disruption, determining recovery priorities, and establishing recovery requirements.
The BIA helps the organization determine:
- Which business services are critical
- What happens if they become unavailable
- How quickly they need to be recovered
- How much data loss is acceptable
- Which information is critical
- Which technology and suppliers support the service
- Which people and skills are required
- What minimum level of service is required
- What dependencies could prevent recovery
- Where continuity and recovery investment is required
BIA answers the business question: “What would happen if this service stopped, and how quickly do we need it back?”
2. When to Perform a BIA
Perform or review a BIA when:
- A new critical business service is introduced
- A major business process changes
- A new technology platform is introduced
- The organization enters a new market
- A critical supplier changes
- Cloud architecture changes
- Significant incidents occur
- Recovery requirements change
- RTO/RPO requirements change
- There is a significant regulatory or contractual change
- Business continuity plans are updated
- Disaster recovery architecture changes
- Periodic BCP/DR review is performed
The review frequency should be defined based on business criticality and risk.

| Reputation Impact | ☐ | ☐ | ☐ | ☐ |
| Safety/People Impact | ☐ | ☐ | ☐ | ☐ |
Overall Criticality: __________________
The organization should define what Low, Medium, High, and Critical mean.
7. Impact of Disruption
Assess what would happen if the service became unavailable or degraded.
Consider:
- Financial impact
- Customer impact
- Operational impact
- Legal impact
- Regulatory impact
- Contractual impact
- Information security impact
- Reputation
- Strategic impact
- Employee impact
- Supplier impact
8. Impact Over Time
Impact often increases as an outage continues.
| Disruption Period | Business Impact | Consequence |
|---|---|---|
| 0–1 hour | ||
| 1–4 hours | ||
| 4–8 hours | ||
| 8–24 hours | ||
| 1–3 days | ||
| 3–7 days | ||
| >7 days |
The time periods should be adapted to the service.
9. Maximum Tolerable Period of Disruption
Determine the maximum period for which the business can tolerate the service being unavailable before the consequences become unacceptable.
MTPD: __________________
Example
A customer-facing SaaS service may have an MTPD of 8 hours because a longer disruption could result in significant customer, contractual, operational, or financial consequences.
MTPD is an organizational business requirement and should be supported by documented impact analysis.
10. Recovery Time Objective
Determine the required recovery time.
MTPD: __________
Target RTO: ______
The RTO should normally be shorter than the MTPD to provide recovery margin.
Example
MTPD: 8 hours
RTO: 4 hours
The organization therefore aims to restore the service within 4 hours rather than waiting until the maximum tolerable disruption period.
11. Recovery Point Objective
Determine how much data loss can be tolerated.
Target RPO: __________________
Consider:
- Transaction frequency
- Data criticality
- Customer requirements
- Regulatory requirements
- Business process requirements
- Backup capability
- Replication capability
Example
RPO: 1 hour
This means the organization requires recovery to a point no more than approximately one hour behind the disruption point, subject to the defined recovery architecture and actual capability.
12. Minimum Business Service Level
Determine the minimum level of service required during disruption.
| Function | Normal Service | Minimum Service |
|---|---|---|
| Customer Login | Full | Required |
| Core Transactions | Full | Required |
| Reporting | Full | Limited |
| Analytics | Full | Not required |
| Administration | Full | Limited |
The minimum service level should be agreed with the Business Owner.
13. Degraded Operations
Determine whether the service can operate temporarily at a reduced level.
Examples:
- Manual processing
- Read-only mode
- Limited customer functionality
- Reduced transaction capacity
- Alternate communication
- Offline processing

40. Relationship With Other ISMS Records
The BIA is a foundational input to:
Business Services
→ Critical Service Register
→ Business Impact Analysis
→ Risk Assessment
→ RTO/RPO Assessment
→ ICT Dependency Register
→ Recovery Strategy
→ Business Continuity Plan
→ ICT Business Continuity Plan
→ Disaster Recovery Plan
→ Backup & Restore Procedure
→ DR Test Plan
→ DR Test Report
→ ICT Recovery Checklist
→ Corrective Action Tracker
→ ISMS Improvement Log
This creates a traceable relationship between business impact and technical recovery requirements.
41. Startup Implementation
A startup does not need a complex BIA for every activity.
Start with the services that could materially affect:
- Customers
- Revenue
- Critical operations
- Sensitive information
- Regulatory obligations
- Contractual commitments
For each critical service determine:
- What does the service do?
- Who depends on it?
- What happens if it stops?
- How quickly must it recover?
- How much data can be lost?
- What technology supports it?
- Which suppliers support it?
- Who is required to recover it?
- What is the recovery strategy?
- Has recovery actually been tested?
42. Minimum BIA Record
For a small organization, the minimum practical BIA can contain:
| Field |
|---|
| Business Service |
| Business Owner |
| Criticality |
| Customers |
| Critical Information |
| Impact of Disruption |
| MTPD |
| RTO |
| RPO |
| Minimum Service Level |
| Key People |
| ICT Dependencies |
| Supplier Dependencies |
| Single Points of Failure |
| Recovery Strategy |
| Workaround |
| Recovery Priority |
| Findings |
| Management Approval |
43. ISO/IEC 27001 Alignment
The BIA supports risk-based information security continuity and recovery planning.
It can provide inputs into:
- Information security continuity
- ICT readiness for business continuity
- Risk assessment
- Risk treatment
- Backup
- Redundancy
- Supplier security
- Incident management
- Disaster recovery
- Business continuity
- Continual improvement
ISO/IEC 27001 does not prescribe one universal BIA methodology, MTPD, RTO, or RPO. These should be established by the organization based on business impact, risk, dependencies, applicable requirements, and recovery capability.
44. Audit Evidence
An auditor should be able to trace:
Business Service
→ Business Impact
→ Criticality
→ MTPD
→ RTO/RPO
→ Critical Information
→ ICT Dependencies
→ Supplier Dependencies
→ Recovery Strategy
→ BCP/DR Requirements
→ Recovery Testing
→ Findings
→ Corrective Actions
→ Risk Treatment
→ Management Approval
This demonstrates that recovery requirements are derived from business needs and risk rather than arbitrary technical assumptions.
45. Final Audit Trail

46. Final Principle
A Business Impact Analysis should not simply list business processes. It should establish what matters most, what happens when it is disrupted, how quickly it must recover, what information must be protected, what the service depends on, and what recovery capability the business actually requires.
Identify → Understand Impact → Prioritize → Define MTPD/RTO/RPO → Map Dependencies → Define Recovery Requirements → Address Gaps → Approve → Review
