###### From Complexity to Clarity: Mapping Interconnections and Interdependencies for Operational Resilience
# \[OR\] \[P2\] \[S2\] \[MII\] \[C20\] Maintaining and Updating Mapping
[](https://cta-redirect.hubspot.com/cta/redirect/3893111/0b279667-64c6-44b6-9618-1127feb5334f)
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 Changes in systems, processes, vendors, and operating environments can quickly render mapping outputs outdated if they are not actively maintained.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.

### **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 Changes in systems, processes, vendors, and operating environments can quickly render mapping outputs outdated if they are not actively maintained.[![\[OR\] \[P2\] \[S2\] \[MII\] \[C20\] Maintaining and Updating Mapping](https://no-cache.hubspot.com/cta/default/3893111/41d34d1f-78bd-4346-845e-b0b86232cfa6.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/41d34d1f-78bd-4346-845e-b0b86232cfa6)
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**
[](https://cta-redirect.hubspot.com/cta/redirect/3893111/b5438182-f1e5-4248-bea5-2d5044665d8d)
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
[](https://cta-redirect.hubspot.com/cta/redirect/3893111/2dbf77a9-2b10-4a06-b39b-ac8f1611e999)
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**.
