The ServiceNow platform providespre-built workflowsthat help organizationsautomate processesacross different domains. These workflows are designed to streamline operations, improve efficiency, and enhance user experience. Thethree primary types of workflowsincluded in the platform are:
Employee Workflows- Designed to improve employee experiences, covering HR services, onboarding, workplace services, and more.
Customer Workflows- Focused on customer service management (CSM), case management, field service management, and proactive customer engagement.
IT Workflows- These workflows enable IT Service Management (ITSM), IT Operations Management (ITOM), and IT Business Management (ITBM) for efficient IT operations.
B: Infrastructure Workflows-No specific "Infrastructure Workflows" exist as a built-in category in ServiceNow. Infrastructure processes are generally managed underIT Workflows (ITOM/ITSM).
C: Federal Workflows-Not an official workflow category. Federal agencies useServiceNow's Government, Risk, and Compliance (GRC) solutions, but this is not classified as a workflow.
D: Manufacturing Workflows-ServiceNow does not have a dedicated "Manufacturing Workflows" category.

The folloing are the benefits of building flows using Flow Designer:
C: Provides natural-language descriptions of flow logic: This allows users without programming experience to understand and modify flows, making them more accessible to a wider range of users.
D: Supports No-Code application development: Flow Designer provides a visual interface and pre-built actions that allow users to automate processes without writing code. This can significantly reduce development time and effort.
A: Supports easy integration with 3rd party systems: Flow Designer integrates with a variety of 3rd party systems through the Integration Hub, making it easy to connect your ServiceNow instance to external applications.
Flow Designer offers a low-code/no-code approach to building automation, simplifies complex logic with natural language descriptions, and integrates seamlessly with external systems.
