`predecessor`은 `OperationObject`에서 설정하고 다른 `OperationObject`를 직접 참조하는게 좋음

Since JobTemplates already define operation_template_sequence, specifying predecessor in OperationTemplate is unnecessary.

Instead, predecessor should be set in OperationObject, referencing another OperationObject directly."

JobTemplates이 operation_template_sequence를 정의하므로 OperationTemplates에서 predecessor을 지정할 필요가 없음.

대신, predecessor은 OperationObject에서 설정하고 다른 OperationObject를 직접 참조하는게 좋음.
