A PERT chart is a project management tool that provides a graphical representation of a project's timeline.
PERT charts are considered preferable to Gantt charts because they identify task dependencies, but they're often more difficult to interpret. A PERT chart helps a project manager analyze a project's tasks and estimate the amount of time required to complete each task in the project. Using this information, the project manager can estimate the minimum amount of time required to complete the entire project. This information also helps the manager develop a project budget and determine the resources needed to accomplish the project.
These nodes are linked by vectors or lines that represent various tasks. Dependent tasks are items that must be performed in a specific manner. For example, if an arrow is drawn from Task No. Items at the same stage of production but on different task lines within a project are referred to as parallel tasks. A well-constructed PERT chart looks like this:. The direction of arrows indicates the flow and sequence of events required for project completion.
Dotted activity lines represent dummy activities—items that are located on another PERT path. These charts have their distinct definitions and terms, the most important of which anticipate how long it will take to finalize a project. The "most likely time" indicates a reasonable estimate of the best-case scenario, whereas "expected time" accounts for problems and obstacles. A PERT chart is similar to a critical path analysis CPA , which is another method that project managers use to chart tasks in a project.
The main difference between the two is that a PERT chart uses various time frames and probability terms when estimating each project stage.
As a project management tool, PERT charts offer some distinct advantages and disadvantages. A PERT chart allows managers to evaluate the time and resources necessary to manage a project. This evaluation includes the ability to track required assets during any stage of production in the course of the entire project.
PERT analysis incorporates data and information from multiple departments. This combining of information encourages department responsibility and it identifies all responsible parties across the organization. These charts can include unreliable data or unreasonable estimations for cost or time for this reason. Continual review of the information provided, as well as the prospective positioning of the project, is required for a PERT chart to be valuable.
PERT charts were first created by the U. Using the PERT model, Navy project managers were able to evaluate the progress of their project, determine the validity of schedules, and estimate the effects of proposed changes to established plans.

Program Evaluation Review Technique (PERT) Chart
The representation of activities in a project in the form of network is one of the most important and simplest techniques adapted in the project management. The reasons for the adaptation of network-based project management are. The network-based project management has wide range of applications includes Industrial Engineering, production and manufacturing, contract management, construction project management, operation research, software project management and so on Pristker, However these techniques have inherent drawbacks that the results obtained are not highly reliable and thus an intriguing technique which incorporates the human-factor Pristker, into consideration is needed. The GERT technique is applied to the scheduling of concrete formwork systems to reinforce the importance of GERT over other project network techniques. Kelly Jr. Later was developed considering not only the logical dependencies between the activities but also the inclusion of resource related to each activity.

Ему не было нужды выискивать Беккера в толпе, выходящей из церкви: жертва в ловушке, все сложилось на редкость удачно. Нужно только выбрать момент, чтобы сделать это тихо.

Приближаясь к пиджаку защитного цвета, он не обращал внимания на сердитый шепот людей, которых обгонял.
Кипя от злости, тот нырнул в стремительно уплотняющуюся толпу. Он должен настичь Дэвида Беккера.
У них всегда все было в полном порядке. - Все когда-то бывает в первый раз, - бесстрастно ответил Бринкерхофф. Она встретила эти слова с явным неодобрением. - Я все проверяю дважды. - Ну… ты знаешь, как они говорят о компьютерах.
Чтобы вы меня убили. - Я не собираюсь тебя убивать. Мне нужен только ключ. - Какой ключ. Стратмор снова вздохнул.
- Я добиваюсь своих целей, но честь для меня важнее.
Она была небольшой, приблизительно, наверное, метр на метр, но очень тяжелой. Когда люк открылся, Чатрукьян невольно отпрянул. Струя горячего воздуха, напоенного фреоном, ударила ему прямо в лицо.
Sientate! - услышал он крик водителя. - Сядьте. Однако Беккер был слишком ошеломлен, чтобы понять смысл этих слов.
