Challenge: Requirements changes
Response:
1. 最好的降低的风险的方法是能够得到通知，在写case之前，或是每个项目状态会议，找出改变的需求引起风险最大的地方，找出那些case受到影响，哪些不会，险些不受变更影响的case。
2. 制定variables or "to be decided"的case目录，以后继续填写。
3. 让制定预算的人知道修订case的成本。
4. 项目管理制定case修订的优先级。
5. 发布不太正确的没有修订的case。让测试人员标出那些需要修改的case，制定计划的时候要考虑测试加维护的时间。
Challenge: Schedule changes
Response:
1. 如果测试日期提前，让项目管理人员讨论出那些case受到影响，如同需求改变一样，让他们选择哪些方面可以冒险。
2. 如果时间允许有1到2个星期培训新人并能进入项目中，可以添加人手，最好有导师可以指导他们工作。
3. 改变写case的次序，优先写最先要测试的case。
4. 把case简化成被测的需求和配置。制定多一些的时间测试这样的case。
5. 让一些人先测试，然后记录测试的过程。
Challenge: Staff turnover
Response:
1. 新员工需要了解有文字记录的项目架构，进度，目标等，口头上的一些信息就丢失了。
2. 新员工更多是关注软件的业务使用，然后才是需求和原型，写出的case较少。
3. 要对新员工进行实用的培训，组好有实践的例子，并在早期对他们的工作进行检查。
4. 让新员工参与需要较高技术的case。
