There are two types of Decision Making; 'pros and cons on one proposal' and 'choose from several proposals'.
"RINGI", a traditional unique Japanese business practices, is a Workflow that is to make a decision over 'one proposal', to approve or not. (Collecting signatures (stamps) from a terrible number of people. So the paper almost looks red.)
In the other hand, the following Workflow is a example of a Selecting Workflow to choose from 'multiple choices'.
In this example, "Host City candidates" will be enumerated in the upstream operation together with study on benefits and problems of each them. And in the "Host City" is determined in the downstream operation. You can put it to practical use such as a serious business of "selection of the seminar venues" or 'choosing destination of company outing', an easy one.
As a matter of course, the options for the final decision will differ each time. That means, even if you want to show the options in the selection interface at the downstream operation, they will not be the same depending on each matter in question. In such a case, I use a technique that to display data which was entered in each line of "String type multiple line" in the upstream process, as "options of the downstream process". For example, if texts in three lines;
Tokyo
Madrid
Istanbul
are entered in the [Host City Candidates] at upstream operation, 'Tokyo/Madrid/Istanbul' will be listed in the Selectbox (or Radio button) of [Host City] in the process of downstream.
