Scheduling a venture might be daunting. Luckily, there are instruments and strategies such because the priority diagramming methodology to assist arrange actions and get all of them completed on time.
Priority diagrams are used to visualise the duties in a venture from begin to end. When you’re not acquainted with the priority diagramming methodology, you’ve come to the precise place. Let’s take an in depth have a look at this system and the way it assists venture managers when scheduling their initiatives.
What Is the Priority Diagramming Technique (PDM)?
The priority diagramming methodology is a venture planning approach that permits venture managers to map out all of the duties in a venture to plan the order wherein they are going to be executed. That is completed through the use of priority diagrams, that are venture community diagrams that present duties, their period and dependencies.
The priority diagramming methodology (PDM) is much like this system analysis and overview approach (PERT), activity-on-node diagramming and the essential path methodology (CPM), as a result of these strategies additionally use venture community diagrams, however every has its key variations.
What Is a Priority Diagram?
A priority diagram is a venture administration chart that represents venture duties and reveals their durations and the duty dependencies between them. Priority diagrams encompass nodes, which characterize duties, and arrows that join them to indicate the duty dependencies to allow them to even be known as activity-on-node or AON diagrams.
Nevertheless, priority diagrams might be labor-intensive and time-consuming. You’ll must manually modify them each time modifications are made to your venture plan.
With strong venture administration software program equivalent to ProjectManager, you may create Gantt charts, a way more highly effective various to priority diagrams. Our on-line Gantt charts permit you to assign duties, set process dependencies, determine the essential path and rather more with only one click on.
Now that we’ve outlined what priority diagrams are, let’s see how process dependencies work within the PDM.
What Are the 4 Sorts of Priority Diagramming Dependencies?
The priority diagramming methodology makes use of the 4 sorts of process dependencies generally utilized in project management. Nevertheless, when carried out with PDM, these process dependencies are additionally known as priority relationships or PDM relationships.
- End to Begin (FS): The exercise can not begin till its previous process has completed.
- End to End (FF): The exercise can not end till its previous process has completed.
- Begin to Begin (SS): The exercise can not begin till its previous process has began.
- Begin to End (SF): The exercise can not end till its previous process has began.
Why Use the Priority Diagramming Technique?
A priority diagram is a superb instrument to precisely develop the project schedule, maintain the work on monitor and meet the deadline. It does this by visually representing the entire venture, making it simpler for venture managers to plan, schedule and monitor duties.
In fact, the best asset to utilizing the priority diagramming methodology is that it exposes task dependencies within the schedule. This helps stop bottlenecks later within the venture—and if there are modifications within the schedule, the priority diagram helps to indicate how these modifications.
Because the priority diagram illustrates the actions and dependencies in a venture, it might assist present what the essential processes and actions are within the schedule. This helps to find out the essential path, which is crucial for project planning and scheduling.

Priority Diagram Instance
A priority diagram is a way used within the essential path methodology and it’s a great way to higher perceive a priority diagram through the use of the essential path as a priority diagram instance. On this case, the critical path diagram is used to determine the essential path in a venture schedule.
The essential path is the longest sequence of duties in a venture and the duties that should be accomplished on time to ship the venture as scheduled.
The essential path methodology template beneath reveals two process sequences, one begins with A and the opposite begins with B. They each have to be completed concurrently to ship the venture. The essential path methodology algorithm is used to calculate the period of the duties after which determine the size of the project timeline. It’s going to additionally determine actions with zero slack, which is how lengthy a process might be delayed earlier than it impacts one other process.
The instance has venture duties represented as nodes, within which is details about these actions. Arrows point out process dependencies.
To the left facet of the priority diagram instance is a desk that lists the venture duties by identify, period and dependencies. These duties are then proven as nodes on the priority diagram, which reveals the anticipated begin and end based mostly on the earliest begin (ES), earliest end (EF), newest begin (LS) and newest end (LF).
- Earliest Begin (ES): The earliest a process can begin based mostly on any previous actions. As a result of exercise A has no predecessors, it might begin instantly so its ES is zero. Then again, the ES for exercise C is 12 as a result of that’s the earliest its previous process might be accomplished.
- Earliest End (EF): The EF of a process is the sum of its ES and its period.
- Newest Begin (LS): The most recent a process can begin within the occasion its previous process takes the longest to complete.
- Newest End (LF): Signifies the most recent time for a process to be completed based mostly on the sum of its newest begin and its period.
Making these distinctions will expose the essential path and, in flip, inform the estimation of a venture schedule in addition to spotlight the work that must be completed to complete a project.
The way to Draw a Priority Diagram
1. Create a Activity Record
Now it’s time to attract your personal priority diagram. The very first thing to do is collect duties, listing them and determine previous duties. At a minimal, your desk ought to listing actions and their predecessor.
2. Establish Activity Dependencies
Now that you simply’ve recognized your venture duties, it’s vital to investigate all of them and determine the potential process dependencies which may exist in your venture. This is likely one of the most vital steps in PDM, as failing to handle any process dependency may have an effect on the priority diagram as a complete. It may end in process, time and schedule management penalties.
3. Put the Info Right into a Diagram
Now it’s time to put out every process or exercise as a node represented by a field. Every field ought to have an arrow that connects it to the subsequent step. The primary process or exercise will begin on the left adopted by the second, which will probably be related by an arrow.
If the subsequent couple of duties or actions has the identical predecessor, they are going to be stacked on prime of each other with two arrows originating from the predecessor. When a process has two predecessors, the arrows from these predecessors each connect with the duty.
4. Add Activity Info to The Nodes
The ultimate step is to point the exercise and the period within the node. That is completed by breaking the field in half, with one half indicating the exercise and the opposite representing the period. In fact, it might get extra sophisticated. Nodes can embrace:
- Float or slack time
- Earliest begin time
- Earliest end time
- Newest begin time
- Newest end time
Totally different Sorts of Challenge Community Diagrams
The priority diagramming methodology is just one of many project network diagram strategies that help with scheduling. Not all are the identical, however every stems from an identical visible illustration of a venture schedule. Extra sorts are launched beneath.
Exercise-on-Node Diagram (AON Diagram)
As acknowledged above, priority diagrams are thought-about a kind of exercise on node diagrams as a result of they use nodes to characterize venture duties and arrows to indicate dependencies amongst them. They’re often drawn left to proper in chronological order.
Challenge Community Diagram (AON Diagram)
A venture community diagram is used to indicate the order wherein actions in a venture are completed. It comes from knowledge collected in a work breakdown structure (WBS). It’s often drawn left to proper in chronological order. A community diagram can be known as the AON diagram.
Important Path Technique
The essential path methodology makes use of a community diagram together with a scheduling algorithm to assist venture managers visualize project workflows and determine the longest sequence of actions in a venture schedule by way of period, which is called the essential path.
These essential actions should be accomplished on time or else they are going to delay the venture supply, which is why venture managers must pay particular consideration to them and allocate enough resources for his or her well timed execution.
Exercise-on-Arrow Diagram (AOA Diagram)
For this diagramming methodology, arrows characterize actions and nodes present milestones in a venture schedule. The relationships between the actions are proven by circles that join a number of of the arrows. The arrow’s size is used to outline the period of the exercise. This methodology solely reveals finish-to-start relationships. It’s additionally known as the activity-on-arrow (AOA) methodology.
Program Analysis and Evaluate Method (PERT)
The PERT chart is similar to the essential path diagram, however there are key variations between the 2. First, the PERT chart is an activity-on-arrow diagram and it calculates the period of duties utilizing three time estimates and a novel system. It reveals the time wanted to finish the venture; particularly, the time required for every of the venture’s duties, which can inform the venture schedule.
Gantt Chart
The Gantt chart is a bar chart utilized in venture scheduling. It creates a venture timeline the place actions are strains of various lengths in response to the period of the duty specified by chronological order.
A Gantt chart is neither an AOA, AON nor a venture community diagram, however fairly an alternative choice to these strategies that’s generally featured in venture administration software program due to its versatility because it goes past venture scheduling.
For instance, ProjectManager’s Gantt chart permits venture managers to make a visible venture schedule, allocate sources, monitor prices, assign duties to crew members and rather more.
Disadvantages of Utilizing Priority Diagrams for Challenge Administration
Whereas priority diagrams are fashionable project management tools, they’ve some disadvantages. For one, they’re time-consuming.
The method of constructing a priority diagram might be tedious, particularly when doing so for a bigger and extra complicated venture. Additionally, when engaged on a big venture, the priority diagram can change into unruly and tough to visualise.
It’s additionally not one of the simplest ways to maintain stakeholders knowledgeable as they may not be acquainted with priority diagrams and, due to this fact, not perceive what they’re exhibiting.
One other subject with priority diagrams is that they’re susceptible to errors. If there are inconsistent or lacking dependencies, durations or constraints, the schedule might be unreliable. The priority diagram will also be deceptive or unrealistic if it doesn’t account for dangers.
