Change Management

 

1. What is Change Management in ServiceNow?

Change Management in ServiceNow is the process of controlling and managing changes to an organization’s IT infrastructure, application services, and processes in a structured, systematic manner throughout the entire lifecycle of a change request. It involves planning, evaluating, authorizing, scheduling, and implementing changes to minimize disruptions and ensure stability.

 

2. Why is Change Management important?

Change Management is important because it helps organizations manage changes in a controlled manner, reducing the risks associated with changes, improving service quality and availability, and minimizing disruptions to business operations.

 

3. What are the different types of changes in ServiceNow?

The different types of changes in ServiceNow include:

Standard Change: Pre-approved, low-risk changes that follow a predefined process.

Normal Change: Changes that require assessment and approval before implementation.

Emergency Change: Changes that need to be implemented urgently to resolve critical issues.

 

4. What is a Change Advisory Board (CAB)?

A Change Advisory Board (CAB) is a group of stakeholders responsible for reviewing and approving change requests. The CAB ensures that changes are thoroughly assessed for potential risks and impacts before approval.

 

5. What is the role of a Change Manager?

The Change Manager is responsible for overseeing the Change Management process, ensuring that changes are properly assessed, approved, and implemented. They coordinate with stakeholders, manage the CAB meetings, and ensure compliance with Change Management policies.

 

6. How do you create a change request in ServiceNow?

To create a change request in ServiceNow, navigate to the Change module, select the type of change (Standard, Normal, or Emergency), fill in the required details such as description, assignment group, and planned start and end dates, and then submit the request for approval.

 

7. What is a risk assessment in Change Management?

A risk assessment in Change Management is the process of evaluating the potential risks and impacts associated with a change. It helps in identifying and mitigating risks to ensure a smooth implementation of the change.

 

8. How can you track the progress of a change request in ServiceNow?

You can track the progress of a change request in ServiceNow by viewing the change record, which shows the current status, approval history, and any related tasks. ServiceNow also provides dashboards and reports to monitor change activities.

 

9. What is the purpose of the change calendar in ServiceNow?

The change calendar in ServiceNow provides a visual representation of scheduled changes, helping to identify potential conflicts and ensuring that changes are planned and implemented without causing disruptions to services.

 

10. How does ServiceNow ensure compliance with Change Management policies?

ServiceNow ensures compliance with Change Management policies by providing automated workflows, approval processes, and audit trails. These features help in enforcing policies, tracking changes, and maintaining accountability.

 

11. What is the purpose of the unauthorized checkbox on the change form?

The unauthorized checkbox is used to flag changes that have not been authorized. This helps in identifying and managing unauthorized changes, ensuring that only approved changes are implemented.

 

12. Can we create multiple risk assessments in a change, and what will be the impact?

Typically, only one risk assessment is created per change to maintain clarity and consistency. Multiple risk assessments can lead to confusion and conflicting risk evaluations, making it harder to manage the change effectively.

13. Can we create a change record in a scoped application?

Yes, you can create a change record in a scoped application. However, it requires proper configuration and customization to ensure it works as expected within the scoped environment.

 

14. How can you demonstrate to a customer that their change process is streamlined?

You can demonstrate this by showing key performance indicators (KPIs) such as reduced change implementation time, fewer failed changes, and improved change success rates. Additionally, presenting a well-documented change process and automated workflows can help illustrate the streamlined process.

 

15. How is the Knowledge Management module related to Change Management?

The Knowledge Management module is related to Change Management as it provides a repository for documenting and sharing information about changes. This includes best practices, lessons learned, and troubleshooting guides, which can help in managing future changes more effectively.

 

16. What prerequisite questions would you ask a client who wants to create a normal change?

Some prerequisite questions include:

What is the objective of the change?

What are the potential risks and impacts?

What resources are required for the change?

What is the planned implementation timeline?

Are there any dependencies or related changes?

 

17. How can you automate the transition of a normal change request to the implementing state when the planned state date is breached?

You can use a scheduled job or a business rule to monitor the planned state date. If the date is breached, the script can automatically transition the change request to the implementing state without manual intervention.

 

18. How can you set up an auto-approval for certain change management flows based on specific conditions?

You can configure approval rules and workflows in ServiceNow to automatically approve changes that meet specific criteria. This can be done using condition-based logic in the workflow editor, ensuring that changes fitting the predefined conditions are auto-approved.

 

19. How do you handle conflicting changes in ServiceNow?

Conflicting changes can be managed using the Change Conflict Detection feature in ServiceNow. This feature identifies potential conflicts by comparing the planned start and end dates of changes affecting the same Configuration Item (CI). If a conflict is detected, the system can notify the Change Manager or the CAB for resolution. Additionally, the change calendar can be used to visualize and manage overlapping changes.

 

20. What is the purpose of the Change Task in ServiceNow, and how is it used?

A Change Task in ServiceNow is used to break down a change request into smaller, manageable tasks. Each task can be assigned to different individuals or groups, allowing for parallel processing and better coordination. Change Tasks help ensure that all aspects of a change are addressed, from planning and implementation to testing and validation.

 

21. How can you automate the approval process for changes in ServiceNow?

The approval process for changes in ServiceNow can be automated using workflows and approval rules. You can define conditions and criteria for automatic approvals within the workflow editor. For example, low-risk changes can be auto-approved based on predefined risk assessment scores, while high-risk changes may require manual approval from the CAB.

 

22. Explain the concept of Change Models in ServiceNow.

Change Models in ServiceNow are predefined templates that standardize the process for specific types of changes. Each model includes predefined fields, workflows, and approval processes tailored to the type of change. Using Change Models ensures consistency, reduces the time required to create change requests, and helps in maintaining compliance with organizational policies.

 

23. What is the role of the Post-Implementation Review (PIR) in Change Management?

The Post-Implementation Review (PIR) is a critical step in the Change Management process. It involves reviewing the change after it has been implemented to assess its success and identify any issues or areas for improvement. The PIR helps in understanding the impact of the change, ensuring that it met its objectives, and capturing lessons learned for future changes.

24. How do you integrate Change Management with other ITSM processes in ServiceNow?

Change Management can be integrated with other ITSM processes such as Incident Management, Problem Management, and Configuration Management. For example, changes can be linked to incidents or problems to track their resolution. Configuration Management Database (CMDB) integration ensures that changes are accurately reflected in the CI records. This integration helps in maintaining data consistency and provides a holistic view of IT operations.

 

25. What are the key performance indicators (KPIs) for measuring the effectiveness of Change Management?

Key performance indicators for Change Management include:

Change success rate: The percentage of changes implemented successfully without causing incidents.

Change lead time: The average time taken from change request submission to implementation.

Change failure rate: The percentage of changes that result in incidents or require rollback.

JavaScript

if (current.state.changesTo('Scheduled')) {

    gs.eventQueue('change.scheduled', current, current.assigned_to.email, current.number);

}

 

29. Write a script to generate a weekly report of changes grouped by their type.

JavaScript

var gr = new GlideAggregate('change_request');

gr.addEncodedQuery('sys_created_onONLast week@javascript:gs.beginningOfLastWeek()@javascript:gs.endOfLastWeek()');

gr.addAggregate('COUNT');

gr.groupBy('type');

gr.query();

while (gr.next()) {

    gs.print(gr.type.getDisplayValue() + ': ' + gr.getAggregate('COUNT'));

}
