Does a layered approach in RPA design help separate different levels of abstraction?

A layered approach in RPA (Robotic Process Automation) design is beneficial because it helps to separate different levels of abstraction, enabling a more organized, maintainable, and scalable automation architecture. This method generally divides the automation tasks into distinct layers, such as presentation, business logic, and data access. By doing so, each layer can be developed, tested, and modified independently, enhancing clarity and reducing the risk of errors.

This structured separation allows for easier upgrades and changes within specific layers without affecting the overall system or other layers. It facilitates better reuse of components and logical grouping of tasks, making both design and maintenance more efficient. For instance, if a change is needed in the business logic, it can be modified without impacting the way data is presented or accessed.

In contrast, a non-layered approach could lead to a tightly coupled design where changes in one aspect cascade and trigger issues across the entire automation solution, making the system more fragile and harder to manage over time.
