客户和供应商已经签署了一份合同，合同中约定了项目需求。由于对此类项目具有非常丰富的经验，项目经理指示计划编制团队绕过制订工作分解结构(WBS)这一过程，直接开始安排资源和任务。项目经理从计划中删掉了客户的其中一项需求，因为根据项目经理的经验认定这项需求是没有必要的。但是在项目进行到一半的时候，人工成本就已经超出预算 30%了。 下列哪个原因最有可能造成这种情况?
The customer and supplier have signed a contract stipulating the project requirements. Due to extensive experience on this type of project, the project manager instructs the planning team to bypass the development of a work breakdown structure (WBS) and begin scheduling resources and tasks. The project manager has dropped one of the customer’s requirements from the plan because the project manager’s experience has shown that it is NOT needed. Midway through the project, the labor costs exceed the budget by 30 percent. To what reason would this MOST likely be attributed?

A.未能成功使用参数估算技术 Failure to use parametric estimating techniques

B.未识别的工作没有列入预算 Unidentified work not being budgeted

C.未能成功使用非参数估算技术 Failure to use non-parametric estimating technique

D.有缺陷的缩减 Flawed contracting
