需求
我们以三国为背景, 假设系统中拥有将军,军师,主公三种角色。
现在作为将军的关羽需要发动一个出征流程。在填写好出兵人数和攻占城市后。
流程流转到军事诸葛亮进行评审, 此时军事可以给出锦囊妙计。
军事同意后,由主公角色刘备进行最后裁断,并赐予战甲等物资。

角色扮演环节
接下来就是各个角色登录系统。完成各自的规定动作。促使整个流程平稳健康的运转。
将军-关羽
- 关羽登录系统在测试流程菜单下发起一个出征流程。
- 关羽可以通过我发起的菜单看到自己的发起记录。
将军-诸葛亮
- 诸葛亮登录系统找到待办任务菜单,查询待办任务。
- 诸葛亮找到已办任务菜单查询自己刚处理过的任务。
主公-刘备
- 刘备登录系统找到待办任务菜单,查询待办任务。
- 刘备找到已办任务菜单查询自己刚处理过的任务。
