Which phase of software design covers the combination of individual components of developed code and the determination of proper interoperability?

Coding refers to the phase where developers write the actual source code for the application components based on design specifications. While it involves creating individual pieces of functionality, it does not encompass the integration and interoperability assessment of those components, which is specifically addressed during testing.

Planning is the initial phase of software design that outlines the project scope, requirements, and design specifications. This stage focuses on defining what needs to be built and how, rather than on the actual integration or interoperability of code components, which occurs later in the testing phase.

Training involves educating end-users or stakeholders on how to use the developed software effectively. This phase typically occurs after testing and deployment, focusing on user experience rather than the technical evaluation of code integration and interoperability, which is the primary concern of testing.
