What is the difference between delivery and deployment processes of a software product?

Delivery processes and deployment processes of a software product are related but have different goals:

• Delivery is the process of preparing and transferring the software product to an environment where it can be deployed. It includes building, testing, packaging, and transferring artifacts (for example, to a repository or a server).

• Deployment is the process of installing and configuring the software product directly in the target environment (production, testing environment, etc.) so that it becomes available for use.

In simpler terms, delivery is preparation and transfer, while deployment is installation and launch. In modern CI/CD practices, these processes can be automated and partially combined.
