Summary	Pass a request through a sequence of handlers until one handles it or the chain ends.	Encapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.	—
Intent	Pass requests along a chain of handlers until one of them handles the request or the request reaches the end of the chain.	Encapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.	Define a creation method behind a common interface so specialized creators can decide which concrete product to instantiate without changing the surrounding workflow.
Decision factors
Problem	A request must pass through multiple possible handlers, but the sender should not need to know which handler will process it.	A system needs to trigger actions without tightly coupling the code that requests an operation to the code that performs it, and it may also need queuing, history, or undo support.	A workflow needs to create one of several related concrete objects, but constructing them directly in client code spreads creation logic and tightly couples the caller to specific implementations.
Tradeoffs	Requests can become harder to trace because control flows through multiple handlers. A long chain may add overhead if many handlers are checked on every request. It keeps handler logic isolated and easier to extend.	Introduces extra classes or objects for each action. Can feel heavier than direct method calls when the workflow is simple. Makes requests more flexible, loggable, and replayable.	Adds extra indirection and more types compared with direct construction Can feel unnecessarily abstract when object creation is simple and unlikely to vary

Integration notes	Chain of Responsibility is useful for validation pipelines, support routing, approval flows, and any system where requests may be processed by different handlers in sequence.	Commands work well for UI actions, background jobs, workflow steps, and undoable operations because invokers can trigger commands without depending on receiver details.	Factory Method is useful when framework hooks, integrations, or environment-specific workflows need to create interchangeable implementations behind a stable contract.
