model stages

Model stages in the context of general knowledge refer to the phases that a concept or idea goes through during development. Initially, there's the **conceptualization stage**, where the idea is formed. Next is the **development stage**, where the idea is refined and tested. Then comes the **validation stage**, where the idea is confirmed through research or experiments. Finally, in the **implementation stage**, the concept is put into practice or integrated into broader knowledge. Each stage is essential for ensuring that ideas are well-formed, reliable, and applicable in real-world situations.
