👉 Hierarchy engineering is a design methodology focused on structuring and organizing elements within a system to optimize performance, efficiency, and maintainability. It involves defining clear levels or tiers of components, each with specific roles and responsibilities, to ensure that the system operates smoothly and effectively. This approach helps in managing complexity by breaking down large systems into manageable, interrelated parts, allowing for easier modification, scalability, and integration of new features. By establishing well-defined interfaces and dependencies between these components, hierarchy engineering ensures that changes in one part of the system do not adversely affect others, promoting robust and adaptable software architecture.
