Which is a critical step in deploying a cartridge in Salesforce Commerce Cloud?

In the context of deploying a cartridge in Salesforce Commerce Cloud, configuring it in Business Manager after upload is indeed a critical step. Once a cartridge is uploaded to the instance, it does not automatically become active or operational; it requires configuration to specify how it should behave within the site's architecture.

This step often includes adjusting settings specific to the cartridge such as altering feature flags, setting up custom configurations, or linking new functionalities to the site's existing features. By properly configuring the cartridge, developers ensure that it integrates smoothly with the existing system, enabling its functionalities to be correctly utilized by the site.

While downloading the cartridge locally, activating it before upload, and creating a new version are all important aspects of managing cartridges, they are preliminary to the actual deployment phase. The ultimate success of a cartridge deployment hinges on the proper configuration in Business Manager, as it dictates how the cartridge will operate within the site before being made available to users.
