In the past year, a company paid US $$60,000 to an external subcontractor for an ongoing project. The project manager has been asked to evaluate if the project can be delivered more cost effectively this year by using internal labor. The project manager used an optimistic term of 4 months, a pessimistic term of 6 months, and a most expected term of 5 months, and has concluded that the service can be delivered with the following resources:* Two engineers (monthly salary of US $$700 each)
* One project manager (monthly salary of US $$1,600)
* Additional estimated monthly expenses of US $$2,000
The project manager used the program evaluation and review technique (PERT) to calculate the savings if the project is delivered with in-house resources. How much money will the project manager estimate the company can save?
在过去一年中,一家公司为一个正在进行的项目向外部分包商支付了6万美元。项目经理被要求评估今年是否可以通过使用内部资源更有效地交付项目。项目经理使用了乐观期限4个月,悲观期限6个月,最可能期限5个月,并得出结论,可以使用以下资源交付服务:
* 2名工程师(每人月薪700美元)
* 项目经理1名(月薪1600美元)
* 估计每月额外开支为2000美元
项目经理使用项目计划评审技术(PERT)来计算使用内部资源交付项目时节省的费用。项目经理估算公司可以节省多少钱?
