Project management involves the planning, scheduling and controlling of the activities in a project Planning — Defining the objectives of the project and listing the tasks. Scheduling — Arranging the tasks in the order in which they are to be performed and allocating the resources. Controlling — Calculating the optimum, durations of each activity and quantity of resources to bring out the successful completion of the project.
Network planning technique can be used for project management. In this technique large projects are broken down to individual jobs or events and arranged in logical network. Network planning helps in planning, scheduling and controlling, in order to complete the project economically in minimum available time with limited available resources. The important terms related to project planning are: Event An event is a specific instant of time, which makes the start or end of an activity.
Event consumes neither time nor resources. Activity An activity is the actual performance of the task and requires time and resources for its completion. It is the work required to complete a specific task. Predecessor activity The activity proceeding to any given activity is called the predecessor activity.
Successor activity The activity succeeding to any given activity is called the successor activity. Duration Duration is the estimated or actual time required to complete a task or an activity. Earliest start time EST It is defined as the earliest possible time at which an activity can start.
It is calculated by moving from first to last event in a network diagram. Earliest finish time EFT It is the earliest possible time at which an activity can finish.
Latest finish time LFT It is calculated by moving from last event to the first event of the network diagram. Latest start time It is the latest possible time by which an activity can start. Float or Slack Stack is with reference to an event and float is with reference to an activity. Float is the difference between time available for completing an activity and the time necessary to complete an activity. Total Float It is the time span by which the starting and finishing an activity can be delayed without delaying the completion of the project.
It is the additional time, which a non critical activity can consume without increasing the project duration. Critical path It is the sequence of critical activities, which decide the total project duration. A critical path consumes maximum resources. It is the longest path and consumes maximum time. It is the one, which connects the events having zero minimum float. It is an event oriented approach used for planning, controlling and reviewing the project.
