If you are a person who specializes in designing and creating ideas for projects, you are probably no stranger to the concept\u00a0PERT diagram<\/a>.\u00a0<\/strong>However, not everyone really understands the functions and uses of this type of diagram. In the article below, let CoffeeHR bring you some information you need to know to apply the PERT network diagram more effectively at work.<\/em><\/span><\/p>\n

What is PERT network diagram?<\/strong><\/span><\/h2>\n

PERT diagram<\/strong>\u00a0(also known as PERT Network) is a type of tool used in building and managing plans\/projects. This chart will show all the factors when implementing a project such as: costs, necessary tools, number of personnel... Through this graphic grid, including employees and leaders You will also understand the implementation process and identify possible problems to prepare solutions.<\/span><\/p><\/blockquote>\n

PERT chart<\/strong>\u00a0will include round\/square dots of different colors, to represent the main goals in a project. Each dot is defined as a step. These shapes are connected by vectors or straight lines, and the various tasks are briefly explained.<\/span><\/p>\n

The current,\u00a0PERT network diagram<\/strong>\u00a0is increasingly widely used, because it is consistent with the trend of solving tasks in a model and simplified manner.\u00a0PERT Network<\/strong>\u00a0It is considered to be highly effective when used with large-scale projects.<\/span><\/p>\n

Situations where PERT diagrams should be used<\/strong><\/span><\/h2>\n

PERT network diagram<\/strong>\u00a0Currently, it is favored and used regularly by many companies and businesses. However, this method is more suitable when used on large-scale projects such as plans to reorganize personnel of departments, or a program to change salaries, costs... Because these plans Most of the time there will be many steps and a complicated process. Simplicity and modeling rolled into one\u00a0PERT diagram\u00a0<\/strong>will help members clearly understand what they need to do.<\/span><\/p>\n

In addition, for projects with large investments, or coordinated with many different departments\/investors, deployment based on network diagrams also helps simplify the process and support work to be done quickly. Fast, highly effective.<\/span><\/p>\n

Understand the 4 main elements when creating a PERT diagram<\/strong><\/span><\/h2>\n

One of the most important things you need to remember when creating\u00a0PERT network diagram<\/strong>\u00a0is to clearly understand the key factors affecting the work process, especially the 4 factors below:<\/span><\/p>\n

Event<\/strong><\/span><\/h3>\n

Each event is considered a milestone marking the start or end of a certain task in the plan. In\u00a0PERT diagram<\/strong>, these milestones are often represented by circles and numbers. The first circle is the starting event, numbered 1 and has only exit lines. And the last circle is the end event, only the representation lines enter. The circles in the middle can have both exits and entrances.<\/span><\/p>\n

Job<\/strong><\/span><\/h3>\n

Work refers to the personnel and time taken to move from one event to another. In\u00a0PERT chart<\/strong>, the work is the lines connecting the circles together, and the length will be estimated based on the length of the line. Unreal jobs will have a curve length of 0, and you can annotate the information on this curve.<\/span><\/p>\n

\"C\u00f4ng<\/span>
Work is a factor that needs attention<\/em><\/span><\/figcaption><\/figure>\n

Time reserve<\/strong><\/span><\/h3>\n

Lead time is the time that allows tasks to be delayed without affecting the overall progress. This is one of the risk factors that you should mark right on the job supply curves. If the work is completed earlier than this time, it can be marked again with small dots on the arc.<\/span><\/p>\n

Critical path<\/strong><\/span><\/h3>\n

The critical path is the line that connects tasks together. The longest critical path length from the start point to the end point of PERT. The critical path is a factor that shows the progress of work. Therefore, if any element on the critical path is delayed, it means that the progress of the plan is also slower than expected.<\/span><\/p>\n

When is it necessary to create a PERT diagram?<\/strong><\/span><\/h2>\n

The manager will use it\u00a0PERT chart<\/strong>\u00a0to evaluate and complete a given project. But there are many other measurement methods, so why should we choose?\u00a0PERT diagram<\/strong>?<\/span><\/p>\n

For beginners, PERT charts are a suitable method when you need to evaluate the progress, required resources, and critical path of a project. We need to consider each step as follows:<\/span><\/p>\n
