Best Practices for Implementing the Walk Phase in CSDM

The Walk Phase of the Common Service Data Model (CSDM) is a critical stage where organizations focus on defining, organizing, and linking Technical Services and their Offerings to Application Services. Think of it as teaching a child to walk: this phase builds on the foundational understanding established in the Crawl Phase and prepares for the more complex tasks in the Run Phase. Just as each step taken by a child is deliberate and builds strength, every action in this phase sets the groundwork for operational excellence.

Here’s a guide to optimizing the Walk Phase for a robust IT service ecosystem.

1. Develop a Comprehensive Technical Service Portfolio

Imagine teaching a child their first words. You start with clear, simple terms before building complexity. Similarly, in this phase, your Technical Services need to be clearly defined and organized for seamless operation.

Why It Matters: The efficiency of your Application Services depends on a well-structured portfolio of Technical Services. These services include critical infrastructure and backend systems like network connectivity, identity management, and storage solutions.

How to Implement:

• Define Technical Services concisely and distinguish their offerings. For example, the service "Identity Management" might include:
• Differentiate offerings by service levels, environments (production or non-production), and geographic scope. This clarity eliminates ambiguity and ensures consistent service delivery.

"Clarity is the foundation upon which efficiency is built."

2. Establish Ownership and Accountability

Teaching responsibility to a child starts with assigning clear roles—cleaning up toys, organizing books, etc. Similarly, defining ownership for Technical Services ensures accountability and high service quality.

Why It Matters: Without clear ownership, the maintenance and reliability of services can falter. Ownership clarity becomes particularly vital for services involving both in-house and outsourced operations.

How to Implement:

• Assign an owner for every Technical Service to oversee management and updates.
• In shared responsibility models (e.g., cloud hosting with owned equipment), document and communicate roles explicitly.

Example: An organization might outsource cloud hosting but retain ownership of network hardware. This split necessitates clear accountability for each aspect.

"Accountability is the anchor of reliability."

3. Prioritize Based on Criticality

Think of a child learning to prioritize tasks—choosing which toy to pick up first. Similarly, not all Technical Services are equally critical. A structured approach ensures attention is focused where it is needed most.

Why It Matters: Some services are vital to business operations, while others are less critical. Focusing resources on the most critical services prevents downtime and ensures continuity.

How to Implement:

• Conduct a Business Impact Analysis (BIA) to rank services by criticality.
• Collaborate with Technical Service Owners to identify the most critical offerings.
• Establish monitoring and change management processes for top-priority services.

"Success lies in doing the most important things first

4. Link Technical Services with Application Services

Just as a child connects dots to form a picture, linking Technical Services to Application Services creates a clear map of dependencies. This linkage is vital for managing the impact of changes or incidents.

Why It Matters: Understanding dependencies between services ensures faster resolution of incidents and smoother operations.

How to Implement:

• Identify the Application Services supported by each Technical Service Offering.
• Document escalation points and support structures for Technical Service Offerings.
• Include data such as approval groups and support teams to streamline processes.

Example: Link "Active Directory Azure Cloud" to all applications it supports. This enables swift action during outages or incidents.

?"When everything is connected, clarity emerges."

5. Map Critical Configuration Items (CIs) and Their Dependencies

Mapping a child’s growth involves understanding physical, emotional, and intellectual development. Similarly, mapping Configuration Items (CIs) involves documenting their interdependencies to enhance system resilience.

Why It Matters: Critical CIs underpin Technical Service Offerings and Application Services. Their dependencies must be understood to prevent disruptions.

How to Implement:

• Identify critical CIs within Technical Service Offerings.
• Map dependencies between these CIs and those of Application Services.
• Document relationships among infrastructure components like SANs, servers, and network equipment.

"Resilience is built by understanding the links that hold the system together."

Leveraging Event Management for Real-Time Insights

Monitoring a child’s progress involves real-time observation and feedback. Similarly, integrating ServiceNow Event Management provides immediate visibility into the health of your IT environment.

Benefits:

• Detect failing CIs in real time.
• Assess cascading impacts on Application Services.
• Reduce Mean Time to Resolve (MTTR) and prevent critical incidents.

Automate for Scalability

As a child grows, tasks that were once manual (e.g., feeding) become automated as they learn independence. Similarly, as data grows during the Crawl and Walk phases, automation becomes essential.

Why It Matters: Manual processes become unsustainable at scale. Automation ensures data accuracy and operational efficiency.

How to Implement:

• Use automated discovery tools to identify and map services.
• Implement automation for change and incident management processes.

?"Scalability is the hallmark of sustainable growth."

Conclusion

The Walk Phase of CSDM is a transformative stage where foundational service models evolve into sophisticated operational systems. By defining Technical Services, establishing ownership, prioritizing criticality, and mapping dependencies, organizations create a robust IT service ecosystem.

This phase is akin to a child mastering their first steps. Each decision, action, and connection builds strength and prepares the organization for the complexities of the Run Phase.

"Great systems, like great journeys, begin with deliberate and measured steps." Embrace these best practices to optimize your Walk Phase and set a strong foundation for future success.
