In top down design, how does the process begin?

In top-down design, the process begins with a broad overview or concept that provides direction for the entire design project. This overarching concept serves as a foundation upon which the whole system or product is built. Starting with a high-level understanding allows designers to break down the overall goal into smaller, more manageable components, defining the essential functions and features before delving into the specifics.

This approach contrasts with other methods, as it emphasizes the vision of the final product right from the outset. By focusing on the concept first, designers can ensure that all subsequent decisions align with the primary objectives of the project, ultimately leading to a cohesive and well-integrated design. The top-down approach is particularly effective for complex projects where understanding the relationship and interaction between components is crucial for achieving the desired outcome.
