In the Software Development Life Cycle, which stage comes directly after design?

• A. Analysis
• B. Deployment
• C. Implementation
• D. Testing

Answer: (C)

Putting the design into action by building the software is the next step after design. The design phase provides detailed plans—architecture, data models, interfaces—and in the implementation stage those plans are turned into actual code. Developers write the source code, create modules, and integrate components to form a functioning product. After this comes testing to verify behavior, then deployment to release the software. The other stages happen at different times: analysis happens before design, while testing and deployment occur after implementation. So the direct next step after design is implementation.
