现代项目的市场竞争越来越激烈,项目的独特性、复杂性和不确定性都越来越大,因而若要使项目团队更具有竞争力,则需要项目管理能控制在更短的工期内以更低的成本完成更高质量的项目要求。然而,由于项目执行过程中普遍出现的人员惰性,即使预设了足够长的安全时间,人们在执行时也不一定能保证完工率。同时,随着项目复杂性的增加,也导致了越来越多的项目在实施过程中出现项目进度超期、项目变动多、关键资源短缺以及项目资源争夺等问题,导致成本的升高。
The market competition of modern projects is more and more intense. The uniqueness, complexity and uncertainty of the projects are increasing. Therefore, to make the project team more competitive, the project management needs to be controlled within a shorter period Achieve higher quality project requirements at a lower cost. However, due to the inertia of personnel generally occurring during the implementation of the project, even if a long enough safe time is preset, people may not be able to guarantee the completion rate when implementing the program. At the same time, with the increase of project complexity, more and more projects lead to problems such as project schedule overdue, multiple project changes, shortage of key resources and project resource competition during the implementation process, resulting in an increase in costs.
