Blog Summary
- ServiceNow’s low‑code platform makes it easier to innovate and helps organizations increase productivity by replacing manual processes with automated workflows.
- Applications can be Out‑of‑the‑Box (OOB), which are pre‑built and ready to configure, or ServiceNow Custom Applications, built from scratch to meet unique needs.
- Custom Applications enable process automation, data isolation, and third-party integration, improving user experience.
ServiceNow allows you to build an application from scratch, even if you have limited coding knowledge. Using tools like App Engine, ServiceNow application development has become easier. With ServiceNow’s low-code, point-and-click tools, you can build an application by setting up tables, forms, workflows, and user interfaces. For more flexibility, you can add custom scripts and advanced features to your application.
This guide walks you through how to create a ServiceNow application step by step, what ServiceNow applications are, and the benefits of creating applications.
What is a ServiceNow Application?
A ServiceNow application is a package of components designed to perform a specific business task for a particular group of users. It serves as a container for data tables, forms, lists, workspaces, APIs, flows, and security rules working together to solve problems efficiently.Â
For example:
- IT service desk application for ticketing
- HR case management for requests from employees
Apart from these, applications can have thousands of files or only a handful. To handle these files, ServiceNow offers a strong framework that focuses on business issues to maintain the database and security.
What are the types of Applications?
In ServiceNow, there are two different types of applications that you get to work with. Before you start creating an application of your own, let us understand them both:
Out-of-the-Box Application
OOB applications in ServiceNow are prebuilt applications that work without a setup for tables, workflows, forms, roles, and scripts. You can configure and extend these applications to match your requirements instead of building the functionality from the ground up.
Custom Application
Custom Applications in ServiceNow are developed from scratch. It is a self-contained set of data tables, business logic, user interfaces, and workflows designed to satisfy a particular business need not served by an existing application.
Knowing the difference between the two will help you decide whether to configure an existing solution or build one for a specific business requirement.
OOB Application vs Custom Application — Comparison Table
| Aspect | OOB Application | Custom Application |
|---|---|---|
| Purpose | It supports common business processes | It meets specific business needs. |
| Development Efforts | Lower, require mainly configuration | Higher, requires design and development |
| Flexibility | Can be configured and extended | Highly Customizable |
| Time to Deploy | Takes lesser time | Takes more time |
| Best for | Standardized, well-established process | Unique or organization-specific processes |
| Example | ITSM, ITOM, CSM | Event Management, Skill Tracking |
Benefits of a Custom Application
Unlike OOB applications, custom applications are used to build something new. It is about solving problems that standard modules can’t solve. The major reasons why businesses choose Custom Applications over others are:
- Process Automation: It digitizes special, manual, or paper-based processes that are not supported by pre-made modules.
- Data Isolation & Security: It uses private application scopes to protect intellectual property, prevent naming conflicts, and restrict data access.
- Third-Party Integration: It uses solutions like Integration Hub to safely connect to external databases, legacy software, and APIs.
- User Experience: It improves the customer experience by creating workspaces, dashboards, and forms that are specific to departmental personas.
- Scalable Growth: Applications on the Now Platform naturally enhance enterprise capabilities without disrupting essential system updates.
With these benefits to businesses, custom applications are definitely an optimal choice. Moving forward, let us understand the steps to create the same.
How to create a Custom Application?
Creating custom applications in ServiceNow requires minimal coding knowledge. Rather, it is a simple click-and-enter process. The steps include:
1. Open App Engine Studio from the ServiceNow All menu, search for App Engine Studio and open it.
2. Start a new application in App Engine Studio, then click Create. Enter the application name and description, select the required application scope and click Continue.
3. Open the Data section and select Add Data or Create a Table. Create the required tables and add fields based on the data your application needs.
4. Configure the forms for viewing records and add UI form elements, action buttons and menus. You can also design dashboards for reporting.
5. Open Flow Designer from the application tools. Select an appropriate trigger, then add the required actions to automate tasks such as approvals, notifications, record updates, or assignments.
6. Now to set roles and access, go to the application’s Roles and Access settings. Create or select the required roles and configure ACLs and permissions to control who can view, create, edit, or delete application data.
7. Use an automated test framework or manual testing to verify forms, workflows, and permissions.
8. After completing testing, review the application and its configurations. Click Publish in App Engine Studio and follow the deployment steps to make the application available to its users.
Creating ServiceNow custom applications or using the default pre-built apps depends on the needs of the business and the problems they solve. Choosing the right application type is an important part of making it easier for your business processes.
Best Practices in Service Application Development
An application in ServiceNow should be easy to use, easy to maintain, and aligned with the real business needs. As you build your application, keep these best practices in mind:
- Use OOB features first: Before creating a custom solution, check whether ServiceNow already offers the required functionality.
- Prefer configuration: Before writing scripts, use tools such as Flow Designer, UI Policies, and other low-code features.
- Easy to manage: Avoid unnecessary tables, fields, workflows, and customizations that can make the app difficult to maintain.
- Plan security: Configure roles and access controls carefully and avoid giving unnecessary permissions to the user.
- Test wisely: Test forms, workflows, permissions, and integrations before deployment, and involve real scenarios during testing.
Conclusion
ServiceNow application development is a process of workflow automation and data security. It integrates with other systems to provide customised user experiences. You can do it more easily with its low-code, point-and-click tools. According to your business requirements, you can either configure an OOB application or build a custom application. For a custom app, you can define the data, set up forms and user interfaces, automate processes with Flow Designer, manage access, test the application, and then publish it. The key is to keep the application simple, use existing ServiceNow features where possible, and build with security, scalability, and future updates.
