Why is each stage a pre-requisite to the next?

Each stage in a process is typically a prerequisite to the next because it builds foundational knowledge or skills necessary for progression. For instance, in education, mastering basic concepts is essential before tackling more complex topics. This sequential learning ensures that individuals have the requisite understanding and competencies to effectively engage with subsequent material, minimizing gaps in knowledge that could hinder overall comprehension and performance. Additionally, each stage often introduces new challenges that prepare individuals for the next level of complexity.
