Project management decisions are mostly made based on money. Now, a business's worth and profit are taken into consideration when making technical decisions. Over 80% of the United States GDP is derived from projects that emphasize money as being an essential component involved in the process. On the other hand, all other aspects of a project are becoming more complex, such as equipment installation, the design and manufacturing process, renovation, and replacement. Thus, these factors must be emphasized when making decisions, as well. The private sector and federal institutions view projects as being the newest avenue for creating profits and keeping the economy afloat. As a result, project management should be considered to be an essential component, because it can recognize citizen-paid taxes and can avoid wasting resources. This study will begin with a discussion of how vital economics can be to the project management and the project environment. Second, this study will address the various kinds of useful economic decisions and decision-making methods. Finally, it will send the importance of decision-making methods in projects, which is particularly true for engineering and technicalt projects.

如何在项目环境和项目生命周期中有效使用经济决策工具

项目管理决策主要是基于金钱做出的。现在，在做出技术决策时会考虑企业的价值和利润。超过 80% 的美国 GDP 来自强调资金是该过程中必不可少的组成部分的项目。另一方面，项目的所有其他方面都变得越来越复杂，例如设备安装、设计和制造过程、改造和更换。因此，在做出决定时也必须强调这些因素。私营部门和联邦机构将项目视为创造利润和保持经济运转的最新途径。因此，项目管理应被视为必不可少的组成部分，因为它可以识别公民缴纳的税款并可以避免浪费资源。本研究将首先讨论经济学对项目管理和项目环境的重要性。其次，本研究将讨论各种有用的经济决策和决策方法。最后，它将传达决策方法在项目中的重要性，对于工程和技术项目尤其如此。
