Activity / Activity Identifier (Activity ID) : A distinct, scheduled portion of work performed during the course of a project. Represented in the schedule with an activity identifier (Activity ID). Activity Description : The activity description for a particular schedule activity typically consists of a brief phrase or label that is assigned to that schedule activity to assist in the differentiation of that particular schedule activity from all others. These activity descriptions are typically used in conjunction with an activity identifier to further assist in their differentiation. It is always a good practice to include a verb in the description as well as make each description unique to improve reporting. Activity Phrase : All projects have a beginning and an end. Within Dash360 interim phases can be defined. Typically there are phases for conceptual design, preliminary design, final design, procurement, fabrication, factory acceptance testing, site acceptance testing, installation, integration and testing, and commissioning. Crashing : A technique used to shorten the schedule duration for the least incremental cost by adding resources. Fast Tracking : A schedule compression technique in which activities or phases normally done in sequence are performed in parallel for at least a portion of their duration. Forward Pass : A critical path method technique for calculating the early start and early finish dates by working forward through the schedule model from the project start date or a given point in time. Backward Pass : A critical path method technique for calculating the late start and late finish dates by working backward through the schedule model from the project end date. Critical Path : The sequence of activities that represents the longest path through a project, which determines the shortest possible duration. Critical Path Activity : Any activity on the critical path in a project schedule. Critical Path Method : A method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model. Free Float : The amount of time that a schedule activity can be delayed without delaying the early start date of any successor or violating a schedule constraint. Total Float : The amount of time that a schedule activity can be delayed or extended from its early start date without delaying the project finish date or violating a schedule constraint. Gantt Chart : A bar chart of schedule information where activities are listed on the vertical axis, dates are shown on the horizontal axis, and activity durations are shown as horizontal bars placed according to start and finish dates. Early Start Date (ES) : In the critical path method, the earliest possible point in time when the uncompleted portions of a schedule activity can start based on the schedule network logic, the data date, and any schedule constraints. Early Finish Date (EF) : In the critical path method, the earliest possible point in time when the uncompleted portions of a schedule activity can finish based on the schedule network logic, the data date, and any schedule constraints. Late Start Date : In the critical path method, the latest possible point in time when the uncompleted portions of a schedule activity can start based on the schedule network logic, the project completion date, and any schedule constraints. Late Finish Date : In the critical path method, the latest possible point in time when the uncompleted portions of a schedule activity can finish based on the schedule network logic, the project completion date, and any schedule constraints. Start Milestone : Start Milestone is a zero duration activity that only has a start date. It is used to mark the beginning of a phase or an important event. Finish Milestone : Finish Milestone is a zero duration activity that only has a finish date. It is used to mark the completion of a phase or an important event. Predecessor Activity : An activity that logically comes before a dependent activity in a schedule. Successor Activity : A dependent activity that logically comes after another activity in a schedule. Path Convergence : A relationship in which a schedule activity has more than one predecessor. Path Divergence : A relationship in which a schedule activity has more than one successor. Summary Activity : A group of related schedule activities aggregated and displayed as a single activity. Project Schedule : An output of a schedule model that presents linked activities with planned dates, durations, milestones, and resources. Schedule Model : A representation of the plan for executing the project’s activities, including durations, dependencies, and other planning information, used to produce a project schedule along with other scheduling artifacts. Schedule Compression : A technique used to shorten the schedule duration without reducing the project scope. Schedule Management Plan :
