In project management, a critical path is the sequence of project network activities that adds up to the longest overall duration, regardless of whether that longest duration has float or not. This determines the shortest time possible to complete the project. "Total float" (unused time) can occur within the critical path.
Milestones can add significant value to project scheduling. When combined with a scheduling methodology such as program evaluation and review technique or the critical path method, milestones allow project managers to much more accurately determine whether or not the project is on schedule. By constraining the dates associated with milestones ...
To develop a project schedule, the following needs to be completed: [6] Project scope; Sequence of activities; Tasks grouped into 5 project phases (conception, definition & planning, launch, performance, close) Task dependencies map; Critical path analysis; Project milestones; In order for a project schedule to be healthy, the following ...
A Gantt chart created using Microsoft Project. Note (1) the critical path is in red, (2) the slack is the black lines connected to non-critical activities, (3) since Saturday and Sunday are not work days and are excluded from the schedule, some bars on the Gantt chart are longer if they cut through a weekend.
PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).. The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
Critical path method (CPM) is a mathematically based modeling technique for scheduling a set of project activities, used in project management. Critical chain project management (CCPM) is a method of planning and managing projects that puts more emphasis on the resources required to execute project tasks.
Critical path drag is a project management metric used to schedule analysis and compression in the critical path method of scheduling. Drag cost is the reduction in the expected return on investment for a project due to an activity's or constraint's critical path drag. It is often used to justify additional resources that cost less than the ...
The CPM method evaluates the sequence of activities, the work effort required, the inter-dependencies, and the resulting float time per line sequence to determine the required project duration. Thus, by definition, the critical path is the pathway of tasks on the network diagram that has no extra time available (or very little extra time)." [25]
