What Practice Area aims to ensure the correct version of the solution is delivered to the customer?

The Practice Area that aims to ensure the correct version of the solution is delivered to the customer is configuration management. This area focuses on identifying, organizing, and controlling changes to the software and other products throughout their development lifecycle. Configuration management helps maintain the integrity of the product's performance and ensures that the product delivered to customers is the one that was intended.

Through configuration management, processes are put in place to track versions and changes, which helps in preventing errors that may arise from using outdated or incorrect versions of product components. This practice not only verifies the product's accuracy but also assists in managing both the baseline documents and the evolving aspects of the project.

While requirements management deals primarily with gathering and managing customer needs and expectations, and project management focuses on the overall planning, execution, and control of a project, neither of these specifically addresses the management of product versions as effectively as configuration management does. Quality assurance, on the other hand, emphasizes ensuring that products meet quality standards but does not inherently cover tracking and management of versions to the same extent as configuration management.

Thus, configuration management plays a crucial role in delivering the accurate and correct version of a solution to the customer.
