[P2] [S2] Chapter 20

Step 7 – Maintaining and Updating Mapping

Introduction

Interconnection and interdependency mapping is not a one-time deliverable—it is a living capability that must evolve alongside the organisation. Changes in systems, processes, vendors, and operating environments can quickly render mapping outputs outdated if they are not actively maintained.

To remain effective, mapping must be:

• Continuously monitored
• Integrated with change management processes
• Reviewed periodically

This chapter outlines how organisations can ensure that mapping remains accurate, relevant, and actionable, supporting ongoing operational resilience.

Purpose of the Chapter

The purpose of this chapter is to:

• Establish approaches for maintaining mapping accuracy over time
• Integrate mapping updates into business and technology changes
• Define review cycles and governance mechanisms
• Ensure mapping supports continuous resilience improvement

Continuous Monitoring

Importance of Continuous Monitoring

Operational environments are dynamic. Dependencies can change due to:

• System upgrades or migrations
• New product launches
• Vendor onboarding or changes
• Infrastructure modifications

Continuous monitoring ensures that mapping reflects current operational realities.

Key Monitoring Areas

Organisations should monitor:

• Changes in technology architecture
• Updates to process workflows
• Modifications in data flows
• New or altered third-party relationships

Monitoring Mechanisms

• Integration with IT monitoring tools
• Automated discovery tools (for systems and infrastructure)
• Incident and problem management feedback
• Regular engagement with business and technology teams

Benefits

Continuous monitoring:

• Reduces risk of outdated mapping
• Improves responsiveness to change
• Supports real-time risk awareness

Change Management Integration

Why Integration is Critical

Mapping must be embedded into change management processes to ensure that updates are made whenever significant changes occur.

Without integration:

• Mapping becomes obsolete
• Dependencies are missed
• Risk exposure increases

Types of Changes Impacting Mapping

• Introduction of new systems or applications
• Decommissioning of legacy systems
• Process re-engineering
• Vendor onboarding or termination
• Cloud migrations and infrastructure changes

Integration Approach

Organisations should:

• Include mapping updates as a mandatory step in change workflows
• Require impact assessment on CBS for all significant changes
• Ensure mapping is updated before or immediately after implementation

Roles and Responsibilities

• Change Owners: Identify and report changes affecting mapping
• CBS Owners: Validate impact on services
• Mapping/Resilience Teams: Update and maintain mapping records

Benefits

Integration ensures that mapping:

• Remains aligned with operational changes
• Supports accurate risk assessments
• Reflects current dependencies

Periodic Review Cycles

Importance of Periodic Reviews

In addition to continuous monitoring, organisations must conduct formal periodic reviews to validate mapping completeness and accuracy.

Review Frequency

Typical review cycles may include:

• Quarterly reviews: For critical CBS
• Annual reviews: Comprehensive mapping validation
• Ad-hoc reviews: Triggered by major changes or incidents

Review Activities

Periodic reviews should include:

• Revalidation of dependencies and interconnections
• Verification against current systems and processes
• Cross-functional stakeholder reviews
• Alignment with risk and resilience frameworks

Use of Testing and Incidents

Reviews should leverage insights from:

• Scenario testing exercises
• Incident and crisis events
• Audit findings

These provide real-world validation of mapping accuracy.

Benefits

Periodic reviews:

• Ensure mapping remains complete and accurate
• Identify gaps and inconsistencies
• Support continuous improvement

Integration with Operational Resilience Lifecycle

Maintaining mapping should be integrated into the broader operational resilience lifecycle, supporting:

• Impact tolerance validation
• Scenario testing updates
• Recovery planning refinement
• Third-party risk management

Mapping becomes a core input into all resilience activities.

Data Governance and Ownership

Importance of Ownership

Clear ownership ensures:

• Accountability for updates
• Consistency in data quality
• Timely maintenance

Governance Practices

• Assign CBS owners responsible for mapping accuracy
• Establish data standards and definitions
• Implement validation and approval processes
• Maintain audit trails of updates

Challenges in Maintaining Mapping

Common Challenges

• Rapid pace of technological change
• Complexity of interdependencies
• Limited visibility into third-party changes
• Resource constraints

Mitigation Strategies

• Use automation where possible
• Prioritise critical CBS
• Strengthen collaboration across functions
• Embed mapping into business processes

Maintaining and updating mapping is essential to ensuring that interconnection and interdependency mapping remains a reliable and effective tool for operational resilience.

By implementing:

• Continuous monitoring
• Integration with change management
• Periodic review cycles

organisations can ensure that mapping remains:

• Accurate
• Relevant
• Aligned with real-world operations

Ultimately, mapping must evolve with the organisation, enabling it to respond effectively to change and maintain resilience in an increasingly complex and dynamic environment.

This concludes the core chapters of this eBook, reinforcing the central message: operational resilience is achieved not just by understanding interconnections, but by continuously managing and adapting them over time.
