Which activity is performed during the design phase of SDLC?

The design phase of the Software Development Life Cycle (SDLC) focuses primarily on how the system will be constructed based on the requirements collected in the earlier stages. Creating architectural models is crucial during this phase as it involves defining the structure of the software system, including the software architecture, components, modules, interfaces, and data for the system. This stage serves as a blueprint for the development team to follow.

Architectural models help in establishing the framework that guides the coding process, ensuring that all components work together effectively. By providing a clear visualization and detailed structure, these models facilitate communication among stakeholders and help identify potential issues before actual coding begins. Thus, creating architectural models is a fundamental activity in the design phase of SDLC.
