The client-approved schedule that reflects the plan for implementing a project. This schedule reflects no status, and is sometimes referred to as the “target schedule.”
Any activity on a [[critical path]]. A delay in a critical activity will delay the project.
关键路径是决定项目最小可能持续时间的活动顺序。当在[[网络图]中查看时），关键路径是到项目结束的最长路径。如果网络图仅包含完成至启动关系，则关键路径上任何活动的延迟都会延迟[[完成日期]]。如果它包含其他类型的关系（SS，FF，SF），这可能并不总是反映在项目管理软件中。 例如，考虑一个包含2个活动的网络：活动A具有10天的持续时间，并且具有与活动B的开始与开始关系的前驱20天。大多数PM软件将表明这两项活动都处于关键路径上，但该软件将允许A延迟10天而不延迟项目完成。事实上，由于软件算法在识别...
The overall project schedule, created by merging individual contract schedules (i.e., designer and construction contractors) and including relationships between activities that are performed and managed by different groups.
The most recent schedule, consisting of actual dates together with the project team’s forecast start and/or finish dates for each activity remaining.
A regularly scheduled status update of the current schedule, reflecting completed work and [[forecast completion]] dates for remaining efforts. See also [[Time Now]].
Defines how one [[activity]] is related to another. A relationship can be one of four types and may include a [[lag]] time: 1. [[Finish to start]] (FS) activity cannot start until another is finished. 2. [[Finish to finish]] (FF) activity cannot fini...
