Business Continuity Score

Who This Is For

• CIO / CTO responsible for infrastructure resilience and board reporting
• IT Managers building or maturing a business continuity programme
• Audit committee members and risk officers who govern IT risk
• Any organisation that has a business continuity plan but has never tested it against the actual state of the infrastructure

The Problem

Enterprise boards are comfortable with financial ratios.

• A debt-to-equity ratio of 2.1 means something specific
• A current ratio below 1.0 triggers a defined response

These numbers are standardised, comparable, and actionable.

IT resilience, by contrast, is usually reported in ways that are either too granular or too vague.

Too granular

• We had 14 incidents this quarter
• 3 were P1
• Mean time to resolution was 2.4 hours
• Network uptime was 99.2%

Too vague

• Our infrastructure is in good shape
• We are investing in modernisation

Neither tells the board what they actually need to know:

If a major disruption happens tomorrow, what proportion of business operations continues, for how long, and at what degraded capacity?

The answer depends on the current operational state of infrastructure.

This state changes daily:

• Hardware ages
• Configurations drift
• Redundancies degrade
• Assumed state diverges from actual state

Most organisations have no system to measure this gap.

They discover it during an incident, when:

• Discovery and remediation happen together
• Pressure is highest
• Cost is highest

Step-by-Step Approach

Step 1: Understand what a BCS measures

A Business Continuity Score is a composite index.

• Range: 0 to 100
• Purpose: Convert infrastructure resilience into a single interpretable number

Six dimensions of BCS

• Visibility Coverage
  Percentage of infrastructure actively monitored before user impact

• Redundancy Readiness
  Presence and testing of failover systems

• Firmware and Patch Currency
  Devices running supported and secure firmware

• Configuration Integrity
  Alignment with known-good configurations

• Alerting Maturity
  Detection before user-reported incidents

• Response Discipline
  SLA adherence and escalation consistency

Score interpretation

• 85+ → Strong resilience
• 70–84 → Manageable gaps
• Below 70 → Structural risk

Step 2: Conduct a real BCS assessment

Assess your actual infrastructure, not documentation.

For each dimension:

• Visibility Coverage → monitored vs unmonitored devices
• Redundancy → identify single points of failure
• Firmware → audit versions and CVEs
• Configuration → review change logs
• Alerting → detection ratio (90 days)
• Response → SLA adherence (last 20 incidents)

The gap between assumed and actual state is the key insight.

Step 3: Establish quarterly BCS reporting

A BCS becomes valuable when tracked over time.

A quarterly report should include:

• Current score vs previous quarter
• Improvements with reasons
• Declines with reasons
• Planned actions to improve score

Example

• Firmware improved from 68% to 84%
• Redundancy declined due to WAN circuit lapse

Why BCS Matters

BCS enables better decision-making.

Instead of:

• Uptime 99.1%

You get:

• One unmitigated WAN failure risk
• Two devices running end-of-life firmware

This is actionable.

Common Mistakes

• Treating the plan as the capability
• Conducting annual instead of continuous assessments
• Reporting in non-actionable language
• Treating resilience as binary
• Improving documentation instead of infrastructure
• Not including resilience in board reporting

Quick Checklist

• Measure monitored vs unmonitored infrastructure
• Identify all single points of failure
• Audit firmware across all devices
• Check 90-day detection ratio
• Review SLA compliance (last 20 incidents)
• Score all six BCS dimensions
• Identify lowest scoring areas
• Create quarterly BCS report template
• Set target BCS for financial year

Final Take

Your business continuity plan defines what should happen.

Your BCS measures whether it actually can happen.

The difference matters.

Organisations that do this well:

• Report BCS quarterly
• Show trend improvements
• Link infrastructure investments to resilience

BCS is not complex.

It is a discipline:

• Continuous measurement
• Honest evaluation
• Board-level clarity
