In other words, the calculation process begins with placing a zero in the Early Start (ES) position of the first activity. The rest of the calculation continues with the use of the following formulas: Early Start = Maximum (or Highest) EF value from immediate Predecessor(s) Early Finish = ES + Duration.

How to create a network diagram Select a network diagram template. ... Name the network diagram. ... Remove existing elements that you don't need on your diagram. ... Add network components to the diagram. ... Name the items in your network diagram. ... Draw connections between components. ... Add a title and share your network diagram.

First approach ? You calculate the network diagram starting on day 0. ... Second approach ? You calculate the network diagram starting on day 1. ... Early Start = EF of predecessor activity + 1. Early Finish = ES + activity duration ? 1. Late Finish = LS of successor activity ? 1. Late Start = LF ? activity duration + 1.

Calculate the path durations The third step is to calculate the duration of each possible path in the network diagram. A path is a sequence of activities that leads from the start to the end of the project. To calculate the duration of a path, you need to add up the durations of all the activities on that path.

Network diagram best practice Only use one start point and endpoint. If there's more than one start or end, you'll end up with multiple networks. ... Don't overlap arrows. As mentioned above, having multiple starts or ends will become confusing. ... Find the critical path. ... Stay consistent with the symbols.

Determine Late Start (LS) and Late Finish (LF) of acitivies in ... - YouTube YouTube Start of suggested clip End of suggested clip Bring it down to the late finish. So this becomes 19 for the very last one. Then you just do insteadMoreBring it down to the late finish. So this becomes 19 for the very last one. Then you just do instead of adding the duration we're summing subtract as we go through.

A network diagram is a graphical representation of a project and is composed of a series of connected arrows and boxes to describe the inter-relationship between the activities involved in the project. Boxes or nodes represent the activity description, and arrows show the relationship among the activities.

To create a Project Schedule Network Diagram, begin by listing all the activities that need to be completed for the project. Then, draw arrows between the activities to show the logical relationships. Finally, add the duration of each activity.
