我们要设计一个审批流程，这将需要一个以上的人的批准 。审批过程将要求批准组的每一个人都批准。 当其中有一个拒绝时，整个批准过程将立即被拒绝。而且，正如预期的那样，他们每个人都需要批准才能获得批准。
对于流程设计，我们需要2个独立的工作流程。
图1：主流程 - 应用流程
图2：个人审批流程
图3：ApproverGroup的映射
按照设计，需要先启动“应用”过程并提交“应用”活动。然后，“生成批准”工具将根据“批准者组”参与者映射中返回的用户数量生成尽可能多的“批准”流程。
每个“批准者”流程实例都会从尊敬的批准者那里收集决策。然后执行“更新应用程序”触发父进程中的“等待响应”活动（“应用”进程），然后执行“进程批准”工具来评估是否足以作出最终决定并前进。
生成审批
We are going to design a Approval flow which would require more than one person's approval. The approval process would require each and every one person of the approval group to approve. When there's one of them rejects, the whole approval process would be rejected immediately. And, as expected, each of them would need to approve in order to get it approved in overall.
For the process design, we would require 2 separate workflow processes.
Figure 1: The main process - Apply Process
Figure 2: Individual Approval Process
Figure 3: Mapping of ApproverGroup
By design, one would need to kick start the "Apply" Process first and submits the "Apply" activity. Then, "Generate Approval" tool would spawn as many "Approval" Process as needed according to the number of users returned in "Approver Group" participant mapping.
Each of the "Approver" process instances would gather decision from its respectful Approver. Then, "Update Application" will execute to trigger "Waiting For Response" activity in the parent process ("Apply" Process) which will then execute the "Process Approval" tool to evaluate if it is enough to make a final decision and move forward.
