This template helps teams model the Chain of Responsibility design pattern by visualizing how requests are passed through a sequence of handlers. It provides space to define each handler’s role, decision logic, and handoff to the next step in the chain. By making request flow and responsibility boundaries clear, the template supports better design decisions, easier maintenance, and clearer communication of complex processing logic.
Illustrate and document the Chain of Responsibility behavioral design pattern with this engineering reference template. This pattern passes a request along a chain of handlers — each deciding to process or pass it along — decoupling senders from receivers. This template maps the handler chain, request flow, and decision logic on a shared Zoom Whiteboard canvas.
Chain of Responsibility architectures are hard to debug without a map. This diagram makes the handler sequence and decision logic visible to every engineer — reducing the "why didn't this handler fire?" questions during code review and incident response.
