What is the sequencing technique used to create a project schedule network diagram?

The project manager is responsible for the completion development of the project. By including planning and aligning the objectives of the project, the process functions smoothly. However, project failure occurs when the project manager fails to execute the created work analysis structure. As a project manager, it is necessary to prepare a plan for your project that includes all the project management skills, knowledge, tools and techniques.

In this article, we will discuss the sequence activities in a project and its process, the importance and necessity to determine activity sequencing on projects.

The strategy of distinguishing and authenticating affiliates amidst the project activities, the Sequence Activities illustrates the consistent planning of work to get the highest effectiveness the project constraints. Throughout the project, the process of execution plans for better performance.

The sequence activities are designed to fall under these project management groups and knowledge areas. By using the results from the procedures, the project schedule development defines sequence activities, estimate activity resources, and estimate activity durations in combination with the scheduling tool to produce the schedule model. The Schedule management plan recognizes what scheduling method and device to use for the task, which will manage the activities to be sequenced.

How to Sequence Activities in a Project?

Sequencing can be performed by utilizing project management softwares or by using manual procedures. The Sequence Activities process focuses on changing the project activities from a list to a diagram to act as a first step to publish the schedule baseline. The below chart portrays the data flow diagram of sequence activities on how every activity except the first and last should connect to at least one predecessor and at least one successor activity with an appropriate logical affiliation.

The process of Sequence Activities in Project Management

Sequence Activities is the process of identifying and documenting relationships among the project activities. So the fundamental reason for the sequence activities process is finalizing the interrelationship of activities to finish the project scope and achieve the task objectives.

The critical consequence of the Sequence Activities process is a Network Diagram. Network Diagram of a project represents the activities in boxes with activity ID and shows the relationship of activities.

Each activity excluding the first and last ought to be associated with at least one predecessor and at least one successor activity with a proper logical relationship. A realistic project schedule ought to be apt by creating logical relationships. It might be essential to utilize lead or lag time between exercises to help a reachable undertaking plan. Sequencing can be performed by using software that is built for project management, manual or computerized procedures. The Sequence Activities process focuses on changing the project activities from a list to a diagram to go about as an initial step to distribute the schedule baseline.

Network Diagram Example for Sequence Activities Process

• Process of identifying and documenting relationships among the project activities

• Key results of this process is Network Diagram

• If activity durations are added, network diagram shows critical path

This figure shows a sample network diagram as a result of the sequence activities process:

As you see, after the start of the project,

Activity 1 must start first.

After Activity 1 finishes, Activity 2 and Activity 3 will begin.

Activity 4 can start only after Activity 2 finishes.

Activity 5 depends on Activity 3. Therefore, it will start only after it is completed

And the last Activity, Activity 6 can start only if Activity 4 and Activity 5 is completed.

After Activity 6 completion, the project will end.

This is just a simple network diagram. In real-life projects, there will be lots of project activities, so the network diagram and also sequence activities process will be much more complicated.

Why is it Important to Determine Activity Sequencing on Projects?

You can not plan your project if you are not fully aware of what activities are to be done. You may also be doing activities that will disrupt future activities. You may also do the shorter activities first and then discover you have run out of time or money.

Precedence Diagramming Method in Sequence Activities

Precedence Diagramming Method is a technique that is utilized to develop a schedule model where activities are signified by nodes which are connected to one or more affiliates to its successors by a projectile.

Precedence Diagramming Method incorporates four kinds of dependencies or logical predecessor-successor relationships:

• Finish-to-Start:

  The successor activity cannot start, until the predecessor activity is complete.

• Finish-to-Finish:

  The successor activity can't be completed until the point that a predecessor activity is complete.

• Start-to-Start:

  A successor activity cannot start unless the predecessor activity has not started.

• Start-to-Finish:

  A successor activity cannot finish until the predecessor activity has not started.

Once the derivation of the connections among the activities of the projects is done, you will receive a sequence that sets-up activities interlinked with each other given their affiliation. This set-up is known as the network diagram of the project.

You can't decide the most challenging way possible for a project unless you sequence activities. Numerous illustrations are similar to the project network diagrams, and hence you strive to track down the most accessible route between two points. You need to take only one point from the illustrations. In a project network diagram, you need to complete all the activities in the project. In the end, when you end with sequencing the project activities, you discover some changes to the inputs used – that is, activity list and activity attributes. There are chances to identify specific risks. So as a project manager, you will update the project documents and other outputs.
