Gann 9 Chart

[Mariela Coxon]

Some15 years after Adamiecki, Henry Gantt, an American engineer and project management consultant, devised his own version of the chart and it was this that became widely known and popular in western countries. Consequently, it was Henry Gantt whose name was to become associated with charts of this type.

Originally Gantt charts were prepared laboriously by hand; each time a project changed it was necessary to amend or redraw the chart and this limited their usefulness, continual change being a feature of most projects. Nowadays, however, with the advent of computers and project management software, Gantt charts can be created, updated and printed easily.

Today, Gantt charts are most commonly used for tracking project schedules. For this it is useful to be able to show additional information about the various tasks or phases of the project, for example how the tasks relate to each other, how far each task has progressed, what resources are being used for each task and so on.

While it is impossible to identify the "best" indicator when it comes to chart analysis, the most commonly-used Gann angles are the 2X1 angle, the 1X1 angle, and the 1X2 angle, reflecting the predicted price changes for each unit of time. A price movement that crosses over one of these lines can be a sign of changing market sentiment.

Gann analysis is controversial in the investing world, with some comparing it to financial horoscopes. Indeed, Gann was a strong believer in astrology and numerology, and frequently wove mysticism into his trading techniques. Although he claimed to have made millions from trading, later researchers learned that Gann's estate was worth only $100,000 at the time of his death.

Gann angles are calculated by drawing lines at certain angles from a significant price point, such as a high or low. The slopes of these lines are determined by the Gann angles, e.g. 1X1 (for a 45 degree angle), 2X1 (for a 60 degree angle) and so on.

A Gantt chart is a type of bar chart[4][5] that illustrates a project schedule.[6] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis.[4][7] The width of the horizontal bars in the graph shows the duration of each activity.[7][8] Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project.[1] Terminal elements and summary elements constitute the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical "TODAY" line.

Gantt charts are usually created initially using an early start time approach, where each task is scheduled to start immediately when its prerequisites are complete. This method maximizes the float time available for all tasks.[4]

Widely used in project planning in the present day, Gantt charts were considered revolutionary when introduced.[10] The first known tool of this type was developed in 1896 by Karol Adamiecki, who called it a harmonogram.[11] Adamiecki, however, published his chart only in Russian and Polish which limited both its adoption and recognition of his authorship.

In 1912, Hermann Schrch [de] published what could be considered Gantt charts while discussing a construction project. Charts of the type published by Schrch appear to have been in common use in Germany at the time;[12][13][14] however, the prior development leading to Schrch's work is unclear.[15] Unlike later Gantt charts, Schrch's charts did not display interdependencies, leaving them to be inferred by the reader. These were also static representations of a planned schedule.[16]

The earliest Gantt charts were drawn on paper and therefore had to be redrawn entirely in order to adjust to schedule changes. For many years, project managers used pieces of paper or blocks for Gantt chart bars so they could be adjusted as needed.[19] Gantt's collaborator Walter Polakov introduced Gantt charts to the Soviet Union in 1929 when he was working for the Supreme Soviet of the National Economy. They were used in developing the First Five Year Plan, supplying Russian translations to explain their use.[20][21]

In the 1980s, personal computers allowed widespread creation of complex and elaborate Gantt charts. The first desktop applications were intended mainly for project managers and project schedulers. With the advent of the Internet and increased collaboration over networks at the end of the 1990s, Gantt charts became a common feature of web-based applications, including collaborative groupware.[citation needed] By 2012, almost all Gantt charts were made by software which can easily adjust to schedule changes.[19]

In a progress Gantt chart, tasks are shaded in proportion to the degree of their completion: a task that is 60% complete would be 60% shaded, starting from the left. A vertical line is drawn at the time index when the progress Gantt chart is created, and this line can then be compared with shaded tasks. If everything is on schedule, all task portions left of the line will be shaded, and all task portions right of the line will not be shaded. This provides a visual representation of how the project and its tasks are ahead or behind schedule.[22]

Linked Gantt charts contain lines indicating the dependencies between tasks. However, linked Gantt charts quickly become cluttered in all but the simplest cases. Critical path network diagrams are superior to visually communicate the relationships between tasks.[23] Nevertheless, Gantt charts are often preferred over network diagrams because Gantt charts are easily interpreted without training, whereas critical path diagrams require training to interpret.[9] Gantt chart software typically provides mechanisms to link task dependencies, although this data may or may not be visually represented.[4] Gantt charts and network diagrams are often used for the same project, both being generated from the same data by a software application.[4]

The Gantt chart was created by Henry Gantt in the early 20th century to improve project planning, scheduling and tracking by illustrating completed work compared to planned work. Today, project managers and team members use Gantt charts to plan projects, create a project schedule, allocate resources and track progress with just one project management tool.

At a basic level, a Gantt chart allows project, program and portfolio managers to easily map out project plans by organizing project tasks on a visual timeline. However, Gantt charts are used for many other purposes in project planning, project scheduling, project tracking and resource management.

The grid of a Gantt chart is where you list project tasks and project scheduling details about them. The Gantt chart grid is the most important component of your Gantt chart because the data you enter here will be used to populate the Gantt chart timeline.

Basic Gantt chart software only allows you to assign tasks to your team members and create project timelines based on the due dates and duration of your project tasks. However, more advanced Gantt chart software like ProjectManager enables you to track other areas of your project.

On the left-hand side is the data grid, where the various phases of the project are outlined. Under each color-coded phase are the tasks associated with it, including WBS, assignees, due dates and other resources needed to execute the scheduled tasks.

The visual timeline on the right is where things get interesting. You can see the entire project in one place, dependent tasks can be linked and milestones added to indicate important dates. Put your Gantt chart knowledge to the test and build one today. Get started for free.

Waterfall project management consists in planning a project in sequential phases. These project phases are planned in advance and then executed in order from beginning to end without making many changes to the original project plan. Gantt charts are ideal to map out such projects as they allow project managers to visualize task dependencies and establish task sequences on a project timeline.

These two project management approaches are used to manage most projects, even though there are other methodologies that can be used for specific industries or scenarios. However, the best way to understand how Gantt charts are used in project management is to look at some Gantt chart examples.

Our construction schedule Gantt chart template also allows you to use other advanced Gantt chart features such as creating project baselines, finding the critical path and tracking the resource utilization and costs for each of your tasks.

This Gantt chart example shows a manufacturing project that consists of creating a product from scratch and then creating a production schedule for manufacturing it. The phases for this manufacturing project are product ideation, design, prototyping, pre-production and production.

Our Gantt chart production schedule template allows you to track each step in the product development process, such as ideating your product, establishing its feasibility, creating a proof of concept, making a prototype, testing its quality and more.

This free Gantt chart template for Google Sheets is similar to an Excel Gantt chart, but it can be accessed by your team members online, instead of having to download a file and store it in their computers. This also means you can collaborate with your team online so any file changes can be seen by anyone with access to it.
