How to Create a New Application in Pega Constellation

What Is Pega?

Pega is a low-code platform designed to help organizations build applications that automate business processes, manage workflows, and make intelligent decisions using AI and rules. It’s widely used across industries like banking, insurance, healthcare, and government to increase efficiency and improve customer experiences.


Creating a New Application in Pega

To create a new application using Dev Studio, follow these steps:

1. Start the Application Wizard

  1. Log in to your Pega environment.
  2. Click Application → New Application.

You’ll be presented with two options:

  • Build from scratch
  • Select an existing application type from Pega’s out-of-the-box (OOTB) offerings

If you click Search all types, you’ll see a list of available applications. Since the Personal Edition includes fewer preloaded apps, we will proceed with Build from scratch.


2. Choose the Application UI Architecture

Pega provides three UI frameworks you can build your app with:

  • Traditional UI
  • Cosmos (modern, flexible, dynamic)
  • Constellation (the latest React-based, component-driven UI model)

For this example, we’ll select Traditional UI, then click Next.


3. Name and Create the Application

Enter a name for your application and proceed to create it.

You will then be prompted to define:

  • User types
  • Roles

For now, we will skip this step and click Done.


4. Why You Don’t See the App Immediately

After creating the application, you might notice that it doesn’t appear in your Application menu.

This is expected.

When Pega creates a new application, it also generates required system assets—one of those is an Access Group. Access Groups determine:

  • Which applications a user can access
  • What permissions and roles they have

Since your operator ID does not yet include the access group for the new application, you cannot access it.


5. Assign the Access Group to Your User

To add access to the new application:

  1. Click your operator name in the lower-left corner.
  2. Select Operator → Application Access.
  3. Search for the Access Group created for your new app.
  4. Add it to your user profile.
  5. Log out and log back in.

After logging in again, your new application will now appear in the Application menu.


Your application is ready! From here, you can start configuring case types, data objects, UI components, and more. Let me know if you want a follow-up tutorial on building your first case type or setting up data structures.
