Arrow Diagram with Example | PDF

What is an Arrow Diagram?

→ An arrow diagram is used to decide the best sequence of a process or event. In this method, the activities are indicated by arrows.

→ This tool is used to decide the critical path.

→ Arrow Diagram is one of the most important parts of New 7 QC Tools (Seven Management and Planning Tools).

→ It helps us for preparing the best schedule for our project.

→ We can use this tool to identify the problems and provide the optimal and feasible solution.

When we can use an Arrow Diagram?

→ We can use this tool - When we have a complex_project or process and we need to make scheduling and monitoring those tasks.

→ Arrow_Diagram is used when we have a surety about the sequence and time taken by all steps of the project or process.

→ If the scheduling of the_project is critical, and if we have a significant advantage of early_project completion or if the_project is late then we have a severe impact at that time we can use Arrow_Diagram.

Components of Arrow Diagram [CPM Method]

→ The Main Elements of the Arrow Diagram are mentioned below

→ A single arrow represents an activity to be performed.

→ The tail of the arrow shows the start of the activity and the head of the arrow shows the end of the activity.

→ The length of the arrow shows the duration of the activity.

Component of Arrow Diagram

→ The most common words that we use in the CPM_Method are explained below.

Float (slack): The float or slack is the amount of time for that the activity can be delayed without the project delay.

Crashing: The crashing is the reduction in the duration of the_project.

Critical_Activity: It is the activity with zero floats.

Activity: The_activity represents the task and also shown by the arrow symbol.

Dummy_Activity: A dummy_activity is represented by a dotted arrow and does not consume any time & resource.

Critical_Path: A Critical_Path is the sequence of critical activities that form a continuous path between the start of a project and the completion of the project

Forward Pass: The early start_time and early finish_time calculated by moving forward through the


Backward Pass: The latest start_time and latest finish_time calculated by moving backward through the network.

Float_activity: It is the difference between its earliest start_time and latest start_time or earliest finish_time and latest finish_time.
