Which activity dependency type is used when the scheduling of the successor determines the timing of when the predecessor must occur?
In the Local Gantt chart, dependencies allow you to define relationships between tasks and visualize the sequence in which they must be completed in order to close a project. Show
There are two steps to creating a dependency—first, identify the predecessor and successor tasks and then establish a relationship between them. By definition, the predecessor is the first task; it controls the start or end date for all related successor tasks. The successor, by contrast, is the task whose start or end date is controlled by the predecessor. A dependency is the relationship between predecessor and successor tasks. Tasks may have multiple predecessors or multiple successors. Before you begin establishing dependencies, it’s important to understand that there are four types:
Dependencies can be managed from the Local Gantt in both the Tasks list and the Schedule. How to Add a Dependency in the ScheduleTo establish a dependency in the Schedule, just connect a line between the start or end dates of the predecessor and successor task bars.
How to Add a Dependency in the Tasks ListWhen establishing dependencies from the Tasks list, you must add a predecessor from the successor task. In other words, you begin with the successor and then add a predecessor to it.

Cascade DependenciesWith the Gantt Chart’s cascade dependencies functionality, any time you establish a dependency or modify a Start and/or Finish date, changes automatically roll down to dependent tasks so you don’t have to manually change the dates of all successors. Here’s how it works:
Note: Adjusting Start and/or End dates does not delete the dependency or change its type. Setting Lag and LeadWhen you establish a dependency, the default delay between predecessor and successor is one day. For instance, with a Finish to Start dependency, the succeeding task will begin on the day after the preceding task ends. You can extend the days between the predecessor and successor tasks by setting a lag. Alternatively, you can create a lead wherein the successor task starts before the predecessor task ends.

WHAT THE MAVENS KNOW Dependency relations are established in the Local Gantt chart, so it's best to make date modifications here. Although you can modify task dates in the Task Tracker, the ability to cascade changes to dependent tasks is not enabled by default.

Which type of scheduling dependency is observed when the initiation of the work of the successor depends upon the completion of the work of the predecessor?FS dependency is the most common. It means that a successor activity can only start after the preceding activity is completed.
What are the 3 types of dependencies?Types of dependencies in project management. Logical dependencies. Also known as causal dependencies. ... . Resource dependencies. This dependency originates from a project constraint as it deals with the availability of shared resources. ... . Preferential dependencies. ... . External dependencies. ... . Cross-team dependencies.. Which type of task relationship does the start date of the predecessor task determine the finish date of the successor task?Start-to-finish (SF) Indicates that the start date of the predecessor task determines the finish date of the successor task. For example, the time when the editing lab becomes available for use determines when the pre-editing task must be complete. This type of relationship is rarely used.
What are the 4 types of activity relationships?There are four possible activity relationships, which are defined in the Project Management Institute's "bible of project management" — The Project Management Body of Knowledge (PMBOK®). The relationships are Finish-to-Start, Start-to-Start, Finish-to-Finish and Start-to-Finish.
