Which activity is NOT part of the integration process?

The activity of developing marketing strategies is not part of the integration process in systems engineering. The integration process primarily focuses on ensuring that different components or systems work together as intended. This includes activities such as documenting integration testing results, verifying and analyzing assemblies, and validating and verifying interfaces, all of which are aimed at confirming that the system's components interact properly and function as a cohesive unit.

On the other hand, developing marketing strategies is typically associated with business planning and product promotion rather than technical integration. This activity falls outside the scope of the systems engineering integration process and addresses how a product will be presented to the market, its branding, or how potential users will be reached, rather than the technical connections and functionalities of system components.
