Okay.. may I made this a bit too complicated.. After some further thinking about that structure I think it would be way more handy to dispatch directly depending tasks inside the initial Job.

E.g. the POST Requests which need to call the operationStatus Ressource should do that inside their jobs after finishing succesfull their Request. Furthermore that way should be better for requests which are followed by a decision making job (listPlacements => decide which placement should be used), because no cache handling are needed that way.

So I will build the jobs in a way that directly depending jobs(tasks) get dispatched inside. That way I capsulate already enough imo.

The big processes still will get builded as chains as otherwise I would duplicate to much code.

May that thinking process helps someone :D At least it helped me.
