In which phase of the Software Development Life Cycle (SDL

The Product Design phase is where the architecture and overall design of the software product are finalized. This phase is crucial because it translates the requirements identified during the Requirement Analysis phase into a blueprint that developers will follow during the Coding phase. The goal of Product Design is to ensure that the architecture of the system is robust, scalable, and capable of meeting all functional and non-functional requirements. Key design patterns and models are selected during this phase, and high-level design (HLD) and low-level design (LLD) documents are prepared. The design phase not only includes creating the technical architecture but also involves planning the database, the data flow, and how different modules will interact with each other. By the end of the Product Design phase, the project should have a well-defined blueprint to guide the development process. Why Other Options Are Wrong: A) Requirement Analysis: This phase focuses on gathering and analyzing user requirements and specifications. The architecture is not designed in this phase; rather, the needs and expectations are defined. C) Coding: This is the phase where actual code is written based on the design documents. The design is already completed by the time coding begins. D) Testing: This phase is meant for verifying and validating that the software works according to the requirements. No new design decisions are made during this phase. E) Deployment: This phase involves delivering the software to users or transferring it to production environments. The design work has long been completed by this stage.
