A project to build a new product consists of a design that uses some of the features of two existing products, but the new product needs to be larger and cheaper than its predecessor. The project manager looks at the files for the two existing products and discusses the impact on the final cost with the engineering director. What technology will the project manager use to estimate costs?
A.建模和成本预测 Modeling and cost forecasting
B.类比估算和参数估算 Analog estimation and parameter estimation
C.专家判断和成本汇总 Expert judgment and cost summary
D.自下而上估算和计划评审技术分析 Bottom-up estimation and plan review technical analysis
参考答案:B
解析:PMBOK(6),P244,7.2.2估算成本:工具与技术。类比估算和参数估算都是使用历史数据和参数值等进行估算的工具。
