Activity/Task - ✔✔Smaller components included in an overall schedule that are
identified for the purpose of planning, scheduling, monitoring, and controlling the
project. Activities are described in terms of time and will they generally consume
resources.
Milestone - ✔✔They mark a significant point in time for reference or measurement.
They have a zero duration. Often, a goal date.
Work Breakdown Structure - ✔✔The master Work Breakdown Structure is a hierarchy
of work that must be completed within the project and groups activities into various
phases (ex: Preconstruction, Foundation, Structure, Finishes, Close-out, etc).
Duration - ✔✔The length of time for an activity, series of activities, or a project.
Reported in schedule software, durations are always in work days not calendar days.

, Lag time - ✔✔Planned delay between tasks.
Relationship - ✔✔defines how an activity relates to the start or finish of another activity
or assignment. Add relationships between activities to create a path through your
schedule from the first activity to the last activity. These relationships, which form the
logic of the project network, are used together with activity durations to determine
schedule dates. An activity can have as many relationships as necessary to model the
work that must be done. You can also identify relationships between activities that are
in different projects; this type of relationship is referred to as an external relationship.
Types of relationships are shown below:
a. Finish to Start relationship (FS)
b. Finish to Finish relationship (FF)
c. Start to Start relationship (SS)
d. Start to Finish relationship. (SF) Note: this is the least seldom used since it is
counterintuitive.
Critical Path - ✔✔Longest path to complete the project. The longest continuous chain of
activities through the network schedule which establishes the minimum overall project
duration.
Baseline Plan - ✔✔Original Schedule
Progress - ✔✔Actual completion status of a task in the schedule.
Resource Calendar - ✔✔A calendar which indicates the working days of a specific
resource. Resources can be people, equipment, or materials.
Summary Task - ✔✔A single line task which summarizes all the tasks indicated within
its group. Usually shown to indicate the total duration of a phase.
