Where does the 'Build' phase of an application take place?

The 'Build' phase of an application is conducted in the development environment. This phase involves actual construction of the application where developers design and implement the functionality based on the requirements. The development environment is specifically set up for this purpose, allowing for coding, integration, and initial testing of features before they are moved to later phases.

In the development environment, developers can use various tools provided by Pega to create and configure the application's components, such as user interfaces, business rules, data models, and workflows. This environment is equipped for iterative development and enables rapid changes, adjustments, and enhancements based on feedback and evolving requirements.

Other environments such as the production environment, business sandbox, and testing environment have distinct purposes that are not focused on the actual building process. The production environment is where the final application operates, the business sandbox allows users to experiment with ideas in a safe space without affecting existing applications, and the testing environment is used primarily for quality assurance to ensure that the application functions as expected before it is released to production.
