Key Considerations Before You Start

Before embarking on custom application development, careful planning and consideration are crucial. The following factors need to be addressed:

1. Define the Problem & Objectives:

   • Clearly define the problem you are trying to solve. What are the pain points that the custom application will address?
   • Set specific, measurable, achievable, relevant, and time-bound (SMART) objectives for the application.
   • Identify the target users and their needs.

2. Platform Governance:

   • Establish a governance framework to manage custom application development effectively.
   • Define coding standards, naming conventions, and best practices.
   • Implement a change management process to ensure smooth deployments and minimize disruptions.
   • Set guidelines for managing application security and data privacy.

3. Security Considerations:

   • Implement robust security measures to protect sensitive data.
   • Follow security best practices for coding, authentication, and authorization.
   • Regularly audit custom applications for vulnerabilities.
   • Adhere to relevant compliance regulations (e.g., GDPR, HIPAA).

4. Scalability & Performance:

   • Design the application to handle future growth and increasing user loads.
   • Optimize code and database queries for performance.
   • Consider using caching mechanisms to improve response times.
   • Monitor application performance and identify bottlenecks.

5. Maintainability & Support:

   • Write clear, well-documented code that is easy to understand and maintain.
   • Create a knowledge base with troubleshooting guides and FAQs.
   • Establish a support process to address user issues and provide timely assistance.
   • Plan for ongoing maintenance and updates.

6. Choosing the Right Development Approach:

   • Low-Code/No-Code Development: ServiceNow’s low-code/no-code capabilities allow citizen developers to build simple applications with minimal coding required, utilizing drag-and-drop interfaces and pre-built components.
   • Pro-Code Development: For more complex applications with specific requirements, pro-code development using JavaScript, Angular JS and server-side scripting provides greater flexibility and control.

7. Licensing Implications: Understand how custom application development impacts your ServiceNow licensing. Consult with your ServiceNow account representative for clarification.

The ServiceNow Custom Application Development Process

The custom application development process on ServiceNow typically involves the following stages:

1. Planning & Requirements Gathering:

   • Document the application’s functionality, features, and user interface.
   • Create use case diagrams and process flows.
   • Define data models and relationships.
2. Design:
   • Design the application’s architecture, including data models, UI, and workflows.
   • Create wireframes and mockups of the user interface.
   • Choose the appropriate development approach (low-code/no-code or pro-code).
   • Plan integrations with other systems.
3. Development:
   • Develop the application using ServiceNow’s development tools and scripting languages.
   • Create UI components, workflows, and business rules.
   • Implement integrations with other systems.
   • Write unit tests to ensure code quality.
4. Testing:
   • Conduct thorough testing to identify and fix bugs.
   • Perform unit testing, integration testing, and user acceptance testing (UAT).
   • Document test results and track defects.
5. Deployment:
   • Deploy the application to a test environment for final validation.
   • Deploy the application to the production environment.
   • Monitor the application’s performance and stability.
6. Maintenance & Support:
   • Provide ongoing maintenance and support to users.
   • Address bug fixes and implement enhancements.
   • Monitor application performance and identify areas for improvement.

Real-World Examples of ServiceNow Custom Applications

The possibilities for custom applications on ServiceNow are vast. Here are a few examples:

1. Employee Onboarding Application:

   • Problem: Manual onboarding processes are time-consuming and inefficient.
   • Solution: A custom application to automate the onboarding process, including task assignments, access provisioning, and training management.
   • Benefits: Reduced onboarding time, improved employee experience, and increased efficiency.
   • Example scenario: A new employee, John Doe, is hired. The HR team uses the custom onboarding app to initiate the process. The app automatically assigns tasks to various departments (IT, Facilities, HR) for provisioning access, setting up workspace, and enrolling in training. John receives automated notifications and instructions, ensuring a smooth onboarding experience.

2. Vendor Management Application:

   • Problem: Difficulty tracking vendor performance, managing contracts, and ensuring compliance.
   • Solution: A custom application to manage vendor information, contracts, performance metrics, and compliance requirements.
   • Benefits: Improved vendor relationships, reduced risk, and increased transparency.
   • Example scenario: The procurement department uses the vendor management app to track the performance of different vendors based on pre-defined KPIs (Key Performance Indicators) like delivery time, quality of service, and cost. The app automatically sends alerts when a vendor’s performance falls below acceptable levels, enabling proactive management.

3. Facilities Management Application:

   • Problem: Inefficient management of facilities requests, maintenance schedules, and space utilization.
   • Solution: A custom application to manage facilities requests, track maintenance activities, and optimize space utilization.
   • Benefits: Improved facilities operations, reduced costs, and increased employee satisfaction.
   • Example scenario: An employee, Jane Smith, reports a faulty air conditioning unit using the facilities management app. The app automatically routes the request to the appropriate maintenance team, tracks the status of the request, and sends notifications to Jane when the issue is resolved.

4. Compliance Management Application:

   • Problem: Difficulty tracking compliance requirements and ensuring adherence to regulations.
   • Solution: A custom application to manage compliance policies, track audits, and automate compliance reporting.
   • Benefits: Reduced risk of non-compliance, improved audit readiness, and increased transparency.
   • Example scenario: The compliance team uses the custom application to track regulatory changes related to data privacy. The app automatically alerts the relevant departments about the new regulations and assigns tasks for updating policies and procedures.
