Let's say I've got a domain class, which has functions, that are to be called in a sequence. Each function does its job but if the previous step in the sequence is not done yet, it throws an error. The other way is that each function completes the step required for it to run, and then executes its own logic. I feel that this way is not a good practice, since I am adding multiple responsibilities, and the caller wont know what all operations can happen when he invokes a method.
My question is, how to handle dependent scenarios in DDD. Is it the responsibility of the caller to invoke the methods in the right sequence? Or do we make the methods handle the dependent operations before it's own logic?
