##### Resilience Without Walls: Crisis Management in Shared-Space Environments
# \[CM\] \[SIT\] \[C3\] Critical Business Services (CBS) Across Boundaries
[](https://cta-redirect.hubspot.com/cta/redirect/3893111/e8f742e5-d14e-46de-8ed1-f0225ce4030f)In traditional Business Continuity Management (BCM), organisations focused on protecting internal operations—ensuring that key processes, systems, and facilities could recover following a disruption.
However, in today’s **shared-space and interconnected environments**, this approach is no longer sufficient.
Organisations now operate within ecosystems where **critical business services (CBS)** extend beyond organisational boundaries.
These services are often supported by **shared infrastructure, external partners, and inter-agency dependencies**, making them vulnerable to disruptions that originate outside direct organisational control.
In environments such as **Punggol Digital District**, where multiple entities coexist and collaborate, service continuity depends not only on internal resilience but also on the resilience of the **broader ecosystem**.
This chapter introduces the concept of **Critical Business Services Across Boundaries**, emphasising the need to identify, understand, and manage services that rely on shared environments and external dependencies.

### **Chapter 3**
### **Critical Business Services (CBS) Across Boundaries**
#### **Introduction**
[![\[SIT\] \[C3\] Critical Business Services Across Boundaries](https://no-cache.hubspot.com/cta/default/3893111/c963ac7c-f5c0-4162-9580-65520002add0.png)](https://cta-redirect.hubspot.com/cta/redirect/3893111/c963ac7c-f5c0-4162-9580-65520002add0)In traditional Business Continuity Management (BCM), organisations focused on protecting internal operations—ensuring that key processes, systems, and facilities could recover following a disruption.
However, in today’s **shared-space and interconnected environments**, this approach is no longer sufficient.
Organisations now operate within ecosystems where **critical business services (CBS)** extend beyond organisational boundaries.
These services are often supported by **shared infrastructure, external partners, and inter-agency dependencies**, making them vulnerable to disruptions that originate outside direct organisational control.
In environments such as **Punggol Digital District**, where multiple entities coexist and collaborate, service continuity depends not only on internal resilience but also on the resilience of the **broader ecosystem**.
This chapter introduces the concept of **Critical Business Services Across Boundaries**, emphasising the need to identify, understand, and manage services that rely on shared environments and external dependencies.
### **Redefining Critical Business Services in Shared Environments**
A **Critical Business Service (CBS)** is defined as a service that, if disrupted, would have a significant impact on:
- Customers or end-users
- Financial stability
- Regulatory obligations
- Organisational reputation
In shared-space environments, this definition must be expanded to include:
#### **Key Dimensions of CBS in Shared Environments**
##### **Cross-Organisational Dependency**
- Services depend on:
##### **Service-Centric Perspective**
- Focus shifts from:
- Emphasis on outcomes rather than assets
##### **Ecosystem Impact**
- Disruption affects:
##### **Implication**
A service is “critical” not just because of its internal importance, but because of its **impact across the ecosystem**.
#### **Types of Cross-Boundary Critical Business Services**
In shared environments, CBS can be categorised based on the nature of its dependencies.
##### **Internally Delivered, Externally Dependent Services**
- Services owned by the organisation but reliant on shared infrastructure
###### **Examples:**
- Digital learning platforms dependent on shared network infrastructure
- Internal systems requiring access to centralised data centres
##### **Joint or Collaborative Services**
- Services delivered through collaboration between multiple organisations
###### **Examples:**
- Research initiatives involving universities and industry partners
- Cross-agency programmes requiring shared platforms
##### **Public-Facing Services**
- Services directly impacting external stakeholders
###### **Examples:**
- Student enrolment and academic services
- Public digital services provided by government agencies
##### **Shared Platform Services**
- Services built on common digital or physical platforms
###### **Examples:**
- Identity and access management systems
- Shared IT infrastructure and applications
##### **Implication**
Many critical services today are **not owned end-to-end by a single organisation**.
#### **Identifying CBS in Shared-Space Environments**
Identifying CBS in shared environments requires a structured approach that considers both **internal and external dependencies**.
##### **Key Questions to Identify CBS**
- What services must continue regardless of access to the facility?
- Which services depend on shared infrastructure or systems?
- Which services involve external stakeholders or partners?
- What are the consequences of service disruption?
- How quickly must the service be restored?
##### **Example: CBS Identification in a Shared Campus Environment**
| **CBS** | **Description** | **Dependency on Shared Environment** | **Impact if Disrupted** |
| --- | --- | --- | --- |
| Teaching & Learning Delivery | Delivery of lectures, tutorials, and assessments | Physical classrooms, digital platforms, and network infrastructure | Disruption to academic continuity |
| Student Services | Enrolment, records, and support services | Shared systems, administrative facilities | Delays in academic processes |
| Digital Platforms | Learning management systems, online portals | Network, cloud infrastructure | Loss of access to services |
| Research & Collaboration | Joint research activities with partners | Shared labs, systems, facilities | Impact on innovation and partnerships |
##### **Takeaway**
CBS identification must extend beyond internal processes to include **external dependencies and shared infrastructure**.
### **Mapping Dependencies of CBS Across Boundaries**
Once CBS are identified, organisations must understand the **dependencies that support it**.
#### **Dependency Categories**
##### **People**
- Internal staff
- External partners
- Cross-agency teams
##### **Process**
- Internal workflows
- Inter-agency procedures
- Regulatory processes
##### **Technology**
- Shared platforms
- Network infrastructure
- Access systems
##### **Third Parties**
- Vendors
- Service providers
- Infrastructure operators
##### **Example: Dependency Mapping**
| **CBS** | **Dependency Type** | **Dependency Detail** | **Ownership** | **Risk if Disrupted** |
| --- | --- | --- | --- | --- |
| Teaching Delivery | Technology | Learning management system | Shared/External | Loss of teaching capability |
| Student Services | Process | Cross-department workflows | Internal | Delays in service delivery |
| Digital Access | Technology | Network and authentication systems | Shared | Inability to access systems |
| Research Services | Third Party | External research partners | External | Project disruption |
##### **Implication**
Dependencies in shared environments are **multi-layered and often outside direct control**.
#### **Challenges in Managing Cross-Boundary CBS**
Managing CBS across boundaries introduces several challenges:
##### **Limited Control**
- Organisations cannot fully control shared infrastructure or external partners
##### **Visibility Gaps**
- Lack of insight into:
##### **Complex Coordination**
- Multiple stakeholders with:
##### **Ambiguity in Accountability**
- Unclear responsibility for:
##### **Cascading Failures**
- Disruption in one area impacts multiple services
##### **Implication**
Managing CBS across boundaries requires **collaboration, transparency, and shared accountability**.
### **Aligning CBS with Operational Resilience**
To effectively manage CBS in shared environments, organisations must align with **operational resilience principles**:
#### **Key Principles**
##### **Service-Centric Approach**
- Focus on maintaining service delivery rather than recovering assets
##### **End-to-End Perspective**
- Consider the entire service chain, including external dependencies
##### **Impact-Based Planning**
- Prioritise services based on their impact on stakeholders
##### **Resilience by Design**
- Build services that can operate across multiple environments
##### **Key Insight**
Operational resilience ensures that **services remain available—even when parts of the ecosystem fail**.
#### **Purpose of This Chapter**
The purpose of this chapter is to:
- Redefine **Critical Business Services (CBS)** in the context of shared environments
- Provide a framework for identifying **cross-boundary services**
- Highlight the importance of **dependency mapping and external awareness**
- Prepare organisations to manage **services that extend beyond their control**
This foundation supports the next stages of resilience planning, including **dependency mapping, strategy development, and scenario testing**.
[](https://cta-redirect.hubspot.com/cta/redirect/3893111/67348ac6-ec24-4d1d-a69a-1ceec730df0e) In shared-space environments, Critical Business Services are no longer confined within organisational boundaries. They are **distributed, interdependent, and reliant on shared infrastructure and external stakeholders**.
This shift requires organisations to move beyond traditional BCM approaches and adopt a **service-centric, ecosystem-aware perspective**.
By identifying CBS across boundaries and understanding their dependencies, organisations can better prepare for disruptions that affect not just their own operations, but the broader environment in which they operate.
Ultimately, resilience is not about protecting individual components—it is about ensuring that **critical services continue to function, regardless of where disruption occurs**.
