一个制造项目预期每周将交付 100，000 件产品，周缺陷率不大于 0.01%。在过去四周内的缺陷率却是 0.3%、0.1%、0.1%和 0.45%。项目经理集合了一支专家队，判定原材料不满足质量规范。项目团队决定将有必要修订原材料检查过程。 项目经理应如何处理这些信息？
A manufacturing project is expected to deliver 100,000 items per week at a weekly defect rate of no more than 0.01 percent. Within the past four weeks, the defect rate was meanwhile 0.3 percent, 0.1 percent, 0.1 percent, and 0.45 percent. The project manager assembles a team of experts that determines that the raw materials do not meet quality specification. The project team decides that a revised raw material inspection process will be necessary. What should the project manager do with this information?
A ：执行优势、劣势、机会与威胁（SWOT）分析 Perform a strengths, weaknesses, opportunities, and threats (SWOT) analysis
B ： 提出变更请求 Initiate a change request
C ：请求额外的质量资源 Request additional quality resources
D ：开展一致成本研究 Conduct a cost of conformance study
正确答案：B
解析：知识点出处：PMBOK 6th 页码：P306 章节：8.3.3.4 变更请求：如果控制质量过程期间出现了可能影响项目管理计划任何组成部分或项目文件的变更，项目经理应提交变更请求，且应该通过实施整体变更控制过程（见 4.6 节）对变更请求进行审查和处理。 修订“原材料检查过程”，需要通过变更流程更改“质量管理计划”。
