# Gantt Chart

Project planning is of paramount importance to ensure the success of your objective and allows you to estimate the necessary resources, establish a schedule and define the expected performance indicators.

Projeqtor offers a wide choice of control levers to best plan your project and in precise conditions.

The Gantt chart is a tool used in planning and project management to visualize the different tasks that make up a project over time.

Note

For large projects, with many sub-projects and activities, the number of lines to be displayed is limited in order not to deteriorate performance, even if the project selector has already contextualized the display.

### Scroll to today

By clicking this button, you force the Gantt display to return to the current day.

### Predecessor and Successor

This functionality allows you to display the predecessors and/or successors of a plannable element (project, activity, milestone, etc.)

Click once on to display the first level of predecessors of the selected element

Double-click to display all predecessors of the selected element

Click once on to display the first level of successors of the selected element

Double-click to display all successors of the selected element.

Click on to clear the selection of the predecessor or successor

[back]

### Quick mode block

In automatic calculation mode, changing most fields causes the schedule calculation to be refreshed.

This specific blocking mode allows you to not update the schedule automatically each time you make changes.

Warning

Some displays may not reflect the correct values

[back]

### Planning calculation

When you make a modification on an element of your project, the project must then be recalculated to take it into account.

You have the option of using the automatic calculation function, which, if you make a modification on the planning screen, and only on this screen, will immediately take this modification into account.

If the modification is made on another screen, even if you have selected automatic calculation then, you will have to restart the calculation on the planning screen.

- Click on to start the activity planning calculation.

- A popup window appears with the list of projects.

- The check boxes in the list area allow you to select one or more projects to recalculate.

Project selection popUp for project calculation

If you have selected one or more projects with Project Selector then the selected projects will be automatically checked.

Choose the date on which you want to recalculate the project.

By checking the “Hide unselected projects” box, you will only have the projects selected in the project selector and they will be automatically checked.

Important

When the schedule calculation takes a long time, with thousands of activities to be scheduled, the existing scheduled work is deleted, then the calculation is performed, and then the new scheduled work is saved.

During the calculation, users who right-click on the activity do not see the data (the scheduled work is deleted). The idea is to delay the deletion of the scheduled work as long as possible, until just before new values are created.

### Automatic run plan

Swith the button to activate automatic calculation on each change.

Only works on the Gantt Planning view.

If the modification of an element is carried out on the dedicated screen of the element, then it is necessary to click again on BUTTON to restart the computation

All modifications about assignement (rate, name or numbers of resources, dates…) done are not displayed on the new planning screen until having, for this purpose, activited the planning calculation, either in an automatic run plan or not.

On the contrary, the screen planning will not change even if modifications have been loaded yet.

> Automatic calculation

> - Differential calculation = calculation of projects requiring recalculation after being modified.

> - Complete calculation = calculation of all projects

The calculations are programmed according to a frequency of CRON type (every minute, every hour, at a given hour every day, at a given time on a given week day, …)

### Quick planning

The objective is to be able to perform a quick schedule calculation when the automatic schedule calculation function is deactivated in order to obtain an initial result directly on the modified tasks without having to recalculate the capacity

Quick planning activate

After modifying an activity, the schedule is recalculated locally to redisplay it without having to call the server.

A call to the server is made in the background to save the modified data and the schedule position of each impacted activity.

Only the activity details are refreshed from the server; the schedule is not refreshed using the server’s data.

Important

Some modifications will necessarily lead to the recalculation of the capacity (from the server).

Consult the impact table.

### Planning validation

Allows you to replace the validated dates with the planned dates.

Activate the right in specific access> Planning access right to see this option.

Store planned dates

With this approach, you validate in a way any possible delay on the activities of your project.

Two actions are available: Always or If empty.

Always

Will overwrite existing values.

If values are entered in the “validated” fields then, they will all be replaced by the planned dates (calculated by the software)

If empty

Will not overwrite existing values.

If the “validated” fields are not completed, then these dates will be replaced by the planned dates.

If the “validated” fields are completed then they will be kept.

### Print and Export the Gantt chart

You can print directly on your printer or export in PDF format or in MS Project format

#### Print planning

Click on the button to print the Gantt chart in A4 and / or A3 format.

The print quality, despite printing or exporting on a reduced scale, remains very qualitative and offers very little loss of detail in the diagram.

#### Export planning to PDF

Allows to export planning to PDF format.

Export can be done horizontally (landscape) or vertically (portrait) in A4 and / or A3 format

with great detail even with a zoom

Export contains all details and links between tasks and also include a pagination.

And the option Repeat Headers allow you to print or export your planning in multiple pages

Export planning to PDF

This feature will execute export on client side, in your browser. Thus the server will not be heavy loaded like standard PDF export does.

It is highly faster than standard PDF export.

Warning

This technically complex feature is highly dependent on the browser and is not compatible with all of them. It is compatible with the latest versions of IE (v11), Firefox, Edge and Chrome. Otherwise, the old export function will be used.

Tip

Forced feature activation/deactivation

> - To enable this feature for all browsers, add the parameter $pdfPlanningBeta=’true’; in parameters.php file.

> - To disable if for all browsers, add the parameter $pdfPlanningBeta=’false’; Default (when $pdfPlanningBeta parameter is not set) is enabled with Chrome, disabled with other browsers

#### Export planning to MS Project

You have the option of exporting XML for MS Project.

Click on the button to start the export.

A user parameter allows you to enter if you want to add the assignments when exporting the project to MS-Project format.

If not, the name of the resources will not be available in the MS-Project application

#### Planning History

When you perform a calculation on the schedule, you can consult its dedicated history.

In parallel with the history of the elements, you can find the names of the projects that you have recalculated, the duration of the calculation and whether it was completed successfully.

Timeline

In case of a calculation error, the term incomplete is indicated and the cause of the error is displayed on mouse hover.

## Project Timeline

You can view the timeline of your projects in the timeline.

The timeline allows you to have a faster visibility on the progress in time of your projects.

Timeline

The timeline offers a linear view of some selected tasks.

You can add/remove tasks to the Timeline with a single right click.

### Reorder and copy

#### Reorder the planning

The selector allows to reorder the planning elements.

Note

Ability to move multiple tasks at one time from one location to another using the key control to select the lines and then dragging and dropping them.

Warning

If you move an activity to a new project, the assigned resource must be allocated to the new project to allow this move.

#### copy lines

You can click on one or more lines to copy them.

Use the Shift key to select consecutive lines and the Control key to select independent lines.

Right-click the selection and choose where you want to copy these lines.

The lines will then be copied after this location.

If any of the copied elements have successors, then the dependencies will be copied as well.

Past lines from wbs

You can choose to copy assignments to schedulable items as well as copy items to a saved state.

[back]

### WBS

Each line corresponds to an element of your project.

This is the structure of your project with all the steps, activities and actions to be carried out to complete it.

In front of each name given to your schedulable element, a dynamic number is assigned.

This number is representative of the level of your element.

If you change the order of the lines by moving elements then these numbers will be automatically updated with all its successors.

Structure list of WBS

The colored blocks in front of the WBS task names reflect the colors of the bars.

- They are red/light red when a task is late.

- They are green/light green when the task is on schedule.

- They are purple when a resource is unavailable for the task.

- They are gray when the item is closed or canceled.

- A1 for Activity #1

- P1 for project #1

- M1 for Milestone #1

- TS1 for TestSession #1

- MG1 for Meeting #1

- PM1 for Periodic Meeting #1

example display for ID and dependencies

Tip

To add multiple predecessors at once, separate the items with a semicolon or comma.

For example A1;A2 or A1,A2.

Important

If user enters just ID, without letter, consider it is an Activity.

Note

For all the rest of the elements that could serve as predecessors, you can enter the full name directly

For example to create a dependency with an Action as predecessor then enter Action#ID.

### Gantt chart’s bars

The bars in the gantt chart graphically represent a line of your WBS structure.

We visualize the start and end dates and therefore the duration of the task.

The bars displayed in the gantt chart can appear with different colors. Each color has a meaning.

Current date bar

Current date bar

Yellow column indicates the current day, week, month or quarter, according to scale selected.

The red line in yellow collumn display the current day and time.

Pale green bar

no charge

Condition: Activities without assigned work - Planned end date < or = Validated end date

Green bar

all is well

Condition: Assigned resources are available and meet workload - Planned end date < or = Validated end date

Pale mauve bar

no charge

Condition: Fast calculation - no calculations between projects were carried out - graphical representation - without load - modifications to the task without taking into account the steering levers - Planned end date < or = Validated end date

Mauve bar

all is well

Condition: Fast calculation - no calculations between projects were carried out - graphical representation - with load - modifications to the task without taking into account the steering levers - Planned end date < or = Validated end date

Pale red bar

no charge and date planned is superior to validated date

Condition: Activities without assigned work - Planned end date > Validated end date

Red bar

Overdue tasks

Condition: Planned end date > Validated end date - Real end date if completed task > Valited end date

Purple bar

Impossible to calculate the remaining work

Condition: If a resource is not or is no longer available on an activity.

The calculator is trying to plan the workload.

The resource assigned to the activity is unable to be planned for this task (absence, calendar, assignment or assignment periods, etc.); then the bar turns purple.

Pink bar

Thanks to the setting on the management of inherited dates, you will be able to display the pink color to indicate that the end date of this task was recovered from a successor element.

Impossible to calculate the remaining work

Condition: Planning can take into account validated end dates of activities as a priority using a global parameter.

When this option is activated, the validated end date, if it is not provided, is automatically inherited from the successor or parent.

In the case of an inheritance and the Planned end date > Validated end date, the bar turns pink.

Pale pink without workload and bright pink with workload.

Inherited date

When the validated dates are inherited then they are displayed in italics and grayed out whether in the list area or the detail area.

[back]

#### Special bars

Some features offer different color codes.

##### Surbooking and overuse bar

Capacity overbooking

Condition: Add extra work time on the standard capabilities of your resources to plan more projects that you will not process.

Surbooking or orveruse view on Gantt chart

See also

Managment of surbooking periods and overuse

##### Surcapacity

Overcapacity of resources

Condition: The capacity of the resource has been changed. It can be under capacity or over capacity. That is to say, it does less or more than its FTE.

Surcapacity view on Gantt chart

See also

Variations in resource capacity

Real work

Work in progress

Condition: the length represents the percentage of completion based on the actual progress (Assigned - Real work) versus the length of the Gantt bar.

Technical progress

Technical progress

Condition: the length represents the percentage of completion of the units of work that you enter manually (Delivered - completed) in relation to the length of the Gantt bar.

The technical progress bar is automatically set to 100% if the activity that carries the production has moved to the done state.

You can display both progress bars at the same time on the Gantt chart bar.

Progress bars for actual work and work units

Consolidation bar

Consolidation Bar

Condition: graphical display of the dates consolidated by the group of planning elements for a project

### Custom colors

You can apply the color of your choice on the bars of the Gantt chart representing activities, milestones and meetings.

If the Planned end date> Validated end date then the bar should be colored red.

In case you have set a custom color, this state will still be indicated by a thin line at the bottom of the bar.

Custom colors on the gantt chart bars

And in the task list, where the indicators remain the original color.

A parameter in the tools box allow to apply the color on the left part of the Gantt chart. See: Apply color on left part

color applied to the left part of the gantt chart

Click on the reset button to come back to original colors.

You can also set a default color based on the activity type.

#### Bars for color blind

With the help of options, whether in the general settings or in the calculation settings, you can change the colors or have new ones.

The color of the bar adapts to color blind people if you have activated the option.

GREEN BAR

the green color of the bar changed to fluorescent green.

Enable this option in user parameters

RED BAR

the red color of the bar changed to striped purple to clearly mark the difference.

#### Item name display

Item name and planned dates on the selected bar

Move the cursor over the bar to display item name and planned dates.

or activate the “show bar name” check box directly on the Gantt view in the planning screen options.

#### Dependency

Dependencies allow to define the execution order of tasks (sequential or concurrent).

All planning elements can be linked to others.

Dependencies can be managed in the Gantt chart and in screen of planning element.

Dependencies between planning elements are displayed with an arrow.

Important

Strict mode for dependencies

The strict dependency mode forces the successor planning element not to start on the same day as the same predecessor but the next day. Even if the task is finished before the end of the day.

To have the successor start on the same day or before the end of the predecessor task, select NO for strict mode or you can also put a negative delay.

The strict dependency mode is a global parameter. By default, the strict dependency mode is set to YES.

##### Create a dependency

To create a dependency, left click on a bar of the gantt (the predecessor) and slide towards the successor.

You can also create dependencies with the predecessor and successor tables at the bottom of the details area.

Remember than the first task always drives the second.

Predecessor and Successor section - In the NAME field, icons are displayed to indicate the type of dependencies

- Click on on the corresponding section to add a dependency link.

- Click on to edit the dependency link.

- Click on to delete the corresponding dependency link.

Dialog box - Predecessor or Successor element

##### Modify a dependency

Click on the arrow which turns orange, a pop up is displayed allowing you to modify the type and one to add a possible delay.

The predecessor and successor elements of the dependencies are displayed at the top of the popup.

Tip

Multi-line selection is possible using `Control` or `Shift` key while clicking.

Dependencies dialog box

You can change the type of the dependancy. An image accompanies the types to make your choice easier.

You can add a delay on the dependancies. The delay can be positive or negative. Negative delay allows overlapping of certain tasks.

The delay is shown on the Gantt chart and the bubble indicating the delay adapts according to the length of the delay.

Delays on dependencies

The dependency line will be extended by as many days as the deadline entered. Otherwise it will start the next day by default.

the strict mode of dependencies

##### Dependency types

ProjeQtOr offers three types of dependency. The fourth type start-End is not represented.

> End-Start

> The second activity can not start before the end of the first activity.

> Start-Start

> The successor can not begin before the beginning of the predecessor. Anyway, the successor can begin after the beginning of the predecessor.

> End-End

> The successor should not end after the end of the predecessor, which leads to planning “as late as possible”.

Anyway, the successor can end before the predecessor. Note that the successor “should” not end after the end of predecessor, but in some cases this will not be respected:

##### Hidden dependencies

When dependencies are hidden, project folded or parent activity folded on the planning view for example, then a pale orange arrow is displayed in front of the selected element

It means that this element has a constraint that is not currently displayed on the planning view.
