Modeling a loop task

[Christian_Pham]

Hi all,

How can I model a negotiation process? Negotiations can be repeated many times until there is an outcome that is either “successful” or “fail”.

Thanks for the support.

There’s lot of ways to model a loop like this. can you describe in more detail what kind of specific tasks, actions and decisions would need to be involved in the process?

Hi Niall,

My case is:

Suppose a customer sends a request for quotation. The sales person receives the request and prepares a quotation. This quotation will have to be reviewed and approved. Once approved, the quotation will be sent to the customer. The customer can accept it to place an order or cancel the request or continue to negotiate to adjust the quotation. The adjusted quotation will also have to be reviewed and approved again. This continues until the negotiation fails or is successful.

Thanks for the detailed description.
As a first iteration - this should do the trick

Thanks Niall,

But the output of task Review and approve quotation can be “accepted” or “rejected”. If “rejected”, quotation may be subject to adjustment or rejection. How would the model change now?

[Niall]

In that case we can add some more gateways

I will take a closer look at your proposed model, so that I can then expand it to a collaboration model.

Thanks again.

I’ve changed the model to the collaboration. Is it right?
