The Software Development Life Cycle (SDLC) consists of several key stages: requirements gathering and analysis, system design, implementation (coding), testing, deployment, and maintenance. In the requirements phase, stakeholders define what the software must achieve. The design phase involves creating architecture and design specifications, followed by implementation where developers write the code. After testing to ensure functionality and performance, the software is deployed for use, and maintenance involves updating and fixing issues post-launch.

The advantage of this theory is that it has stages. In addition, the uniformed public services has groups that go through these stages.

Tuckman's stages of group communication outline the phases a team typically goes through as it develops and works together. The stages are forming, where group members get to know each other; storming, characterized by conflict and competition as members assert their ideas; norming, where the group establishes norms and cohesion; and performing, where the team operates efficiently towards achieving its goals. A fifth stage, adjourning, was later added, referring to the disbanding of the team after its objectives have been met. These stages help in understanding group dynamics and improving teamwork.

There are usually two design stages in SDLC. They are:High-level Design &Low-level Design

The Software Development Life Cycle (SDLC) is a structured process that outlines the stages involved in developing software applications. It typically includes phases such as planning, analysis, design, implementation, testing, deployment, and maintenance. SDLC aims to improve the quality of software and ensure that it meets or exceeds customer expectations by providing a systematic approach to development. By following these stages, teams can manage project risks, enhance collaboration, and deliver functional software efficiently.
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

SDLC refers to a stage all systems naturally undergo, a methodology refers to an approach invented by humans to manage the events naturally occurring in the SDLC
The design stage that comes before the actual design in the Software Development Life Cycle (SDLC) is the requirements gathering and analysis stage. In this phase, stakeholders identify and document the functional and non-functional requirements of the system. This information serves as the foundation for the subsequent design stage, where specific solutions and architectures are developed based on the gathered requirements.

See the graph in the related link. It clearly separates out the differences between PDLC and SDLC.
The Classical Software Development Life Cycle (SDLC) is a structured approach to software development that outlines the stages involved in creating software applications. It typically includes phases such as requirements gathering, system design, implementation, testing, deployment, and maintenance. This model is often represented as a linear or sequential process, where each phase must be completed before the next begins, allowing for clear documentation and structured project management. While effective for smaller projects, the rigidity of the Classical SDLC can be a limitation in more dynamic or complex environments.
The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC
