Title: "Duration Estimation Methods Common Methods and Considerations"

Author: "Heping Xiao/肖和平"

Abstract: In the project management, it will be faced with how to ensure that the project is delivered on time and on budget. The progress plan is the leading factor in project control. It should not only reflect how to arrange the various tasks, but also consider cost savings and maximization of efficiency. In the progress management, project, WBS, and activity duration estimation are also one of the cores of schedule management. If the estimation is inaccurate, it will not only affect the cost estimation, but also affect the resource input and the entire project completion date. Therefore, the activity duration estimation is a result of comprehensive consideration of all factors such as resource input, process method, construction organization, production efficiency, risk identification, project management, site conditions, and external constraints. This article focuses on the core factors that need to be considered for the duration estimation and how to use P6 software to achieve the duration estimate.

工期估算方法常见方法和注意事项

摘要

在项目管理中，都会面临如何确保项目按时、按预算交付，其中进度计划又是项目控制的龙头，不仅要体现如何去统筹安排各项工作，还要考虑节约成本，效率最大化。而在进度管理中，项目、WBS、活动的工期估算又是进度管理中的核心之一，若估算不准确，不仅会影响到成本估算，而且也会影响到资源投入及项目整个的完成日期。因而，活动的工期估算是综合考虑了资源投入、工艺方法、施工组织、生产效率、风险识别、项目管理、现场条件、外部约束条件等一切因素之后的成果。本文重点介绍工期估算需考虑的核心因素及如何借助P6软件来实现工期估算。
