Change Management is a critical process in IT service management (ITSM) that ensures standardized procedures are used to implement changes to IT infrastructure and services, minimizing risks and negative impacts on business operations. ServiceNow Change Management provides a structured framework to handle change requests, approvals, implementation, and reviews, ensuring that changes are made efficiently and effectively.
In this comprehensive guide, we will explore the various components, workflows, and best practices for using ServiceNow Change Management.
What is Change Management in ServiceNow?
Change Management in ServiceNow is an ITIL-aligned process that controls the lifecycle of changes to IT services, applications, and infrastructure. The primary goal of Change Management is to enable the safe, efficient, and controlled implementation of changes, ensuring minimal disruption to business operations.
Changes can range from simple configuration updates to major system upgrades or deployments, and they need to be handled carefully to avoid unintended consequences.
The core objectives of Change Management are:
- Minimize the risk and impact of changes.
- Ensure standardized processes for managing all changes.
- Provide visibility into the status and progress of changes.
- Improve communication between teams during the change process.
Types of Changes in ServiceNow
Changes in ServiceNow are classified into several categories based on the level of risk, complexity, and impact. These categories help in determining the appropriate approval workflows and implementation steps.
1. Normal Change
A Normal Change is a change that must go through the complete approval and planning process. This type of change is used for changes that are not urgent and have sufficient lead time for analysis, approval, and scheduling.
Key Features:
- Requires a detailed risk assessment and approval from the Change Advisory Board (CAB).
- Goes through multiple stages, including planning, testing, and review.
- Used for changes with medium to high risk and impact.
2. Standard Change
A Standard Change is a pre-approved change with minimal risk and a well-known process for implementation. Since these changes follow a predefined, documented procedure, they do not require approval every time they are implemented.
Key Features:
- Pre-approved and low-risk changes.
- Frequently recurring changes like software patching or routine maintenance.
- No CAB approval required, reducing time for execution.
3. Emergency Change
An Emergency Change is a high-priority change that needs to be implemented immediately due to a critical issue or an unplanned event, such as a major service outage or security breach. These changes are implemented as quickly as possible to restore services or address urgent risks.
Key Features:
- High-risk and time-sensitive changes.
- Requires expedited approval, often by a subset of the CAB or designated approvers.
- Post-implementation review is required to ensure the emergency change was handled appropriately.
Change Management Lifecycle in ServiceNow
The Change Management Lifecycle in ServiceNow consists of several stages, each of which is designed to ensure that changes are thoroughly planned, reviewed, and implemented.
1. Change Request Creation
The process begins with the creation of a Change Request (CR). A CR can be submitted by any authorized user within the organization and includes key information such as:
- Change Type: Normal, Standard, or Emergency.
- Description: A detailed explanation of the change.
- Category and Subcategory: Classifying the change for easier tracking.
- Justification: Why the change is necessary and its expected benefits.
- Impact and Risk Assessment: An analysis of potential impacts and risks associated with the change.
2. Risk and Impact Assessment
ServiceNow provides a risk assessment framework that allows the change owner to evaluate the potential impact and risks associated with the change. The risk level is determined based on factors like:
- Number of users affected.
- Criticality of the system or service.
- Complexity of the change.
Based on the risk assessment, the system may automatically assign priority to the change, and additional approval steps may be added if the risk is deemed high.
3. Change Approval
The approval process is an essential part of Change Management. Depending on the risk and type of change, different levels of approval may be required.
Normal changes typically require approval from the Change Advisory Board (CAB), which consists of stakeholders, technical experts, and service owners. Emergency changes are fast-tracked for approval and may only require a subset of the CAB or designated emergency approvers.
Standard changes are pre-approved and do not require additional approvals.
4. Change Planning and Scheduling
Once a change is approved, it moves into the planning and scheduling phase. This phase ensures that the change is implemented at a time that minimizes disruption to business operations.
Key considerations during planning include:
- Scheduling the change for a non-peak time.
- Ensuring that all necessary resources (people, tools, etc.) are available.
- Communication with stakeholders and affected users.
5. Change Implementation
After the change is scheduled, the implementation phase begins. The change owner or implementation team executes the change based on the predefined plan.
- Work Notes: Detailed work notes are added to the change request to track the progress of the change.
- Status Updates: The status of the change is updated at each step to provide visibility into the process.
6. Testing and Validation
Once the change is implemented, the next step is to test and validate that the change was successful. This may involve testing the functionality of the updated system, running diagnostics, or soliciting feedback from end-users.
Key aspects of testing include:
- Back-out Plans: In case the change causes issues, a back-out or rollback plan is prepared to restore the system to its previous state.
- Success Criteria: Clear criteria for determining whether the change was successful.
7. Change Review and Closure
After testing is complete and the change is deemed successful, the change request moves into the closure phase. Before closing the change, a post-implementation review (PIR) may be conducted to evaluate:
- Whether the change achieved its intended outcome.
- Any lessons learned or areas for improvement in the change process.
- Documentation of the results for future reference.
Key Features of ServiceNow Change Management
ServiceNow Change Management includes several powerful features that help streamline the change process and ensure that changes are implemented effectively.
1. Change Advisory Board (CAB) Workbench
The CAB Workbench is a specialized interface that allows members of the Change Advisory Board to review, assess, and approve changes in a collaborative environment. It provides visibility into all pending changes, their impact, risk, and priority, enabling informed decision-making.
Key Features:
- A calendar view of scheduled changes.
- Integrated risk assessment and prioritization.
- Automated workflows for reviewing and approving changes.
2. Automated Workflows
ServiceNow automates the entire change lifecycle using predefined workflows that route change requests to the appropriate approvers, assess risk, and track the status of changes in real-time. This reduces manual intervention, speeds up the approval process, and ensures that changes are handled consistently.
3. Risk Assessment and Change Collision Detection
ServiceNow's Change Management module automatically assesses the risk of each change based on factors such as scope, impact, and historical data. Additionally, it detects potential collisions with other changes that are scheduled for the same time, helping avoid conflicts and service disruptions.
4. Change Templates
Standardized change templates can be created for recurring changes. These templates ensure that common changes, such as system updates or patch management, follow a consistent process without requiring re-approval each time.
5. Change Calendar
The Change Calendar provides a visual representation of all scheduled changes, helping IT teams plan changes more effectively and avoid conflicts with other events or service outages. This calendar ensures visibility into all ongoing and upcoming changes.
Benefits of ServiceNow Change Management
