Refers to the most effective sequence of activities in a project which minimizes the time needed to complete the project. It is usually shown in a network diagram by double striking the critical activities.
Critical path analysis
A project management tool which serves to improve the efficiency in the production process by systematically scheduling tasks and resources. The ultimate purpose of CPA is to identify the minimum amount of time needed to complete a project.
A logical dependency between two indirectly linked tasks in a project. It is used to prevent an illogical path from being followed and is shown by a dotted line on the network diagram.
Earliest start time (EST)
Shows when a particular activity can begin. It is shown in the top right hand part of a node. The EST will depend on the duration of all previous activities.
Refers to the spare time that is available. It can be inferred by looking at the difference between the EST and LFT for each category.
Latest finishing time (LFT)
The deadline for a particular activity so that the entire project can be completed in the minimum time. It is shown in the bottom right hand part of a network node.
Appear on a network diagram and show the start and finish times of each activity within a project. Each node is numbered to identify the sequence of activities in the project.
Involves the planning and coordination of a variety of different jobs and tasks in a particular project. It is especially important when dealing with large assignments and developments.
