What is Planning and Design in the SDLC?

• A. The phase in the SDLC in which the technical and user interface designs take place.
• B. Coding phase.
• C. Testing phase.
• D. Deployment phase.

Answer: (A)

Planning and design is the stage where the system’s structure and how users will interact with it are defined before any code is written. In this phase, architects lay out the overall architecture, choose technologies, and produce detailed designs for components, data models, interfaces, and the user interface—often with prototypes or mockups. This blueprint guides developers when they start coding and helps ensure the final product meets requirements and is usable. Coding comes next as the actual implementation, while testing verifies the system and deployment releases it to users. The description that emphasizes creating technical designs and user interface designs during this phase best reflects its purpose.
