Once the objectives and deliverables have been defined, the project plan is developed, which includes defining the schedule of activities and assigning the necessary resources for their completion. The schedule of activities must be realistic and take into account possible delays and risks associated with the project.

It is important to note that project planning is not a static process, but should be updated as the project progresses and new needs or risks are identified. It is recommended to use project management tools, such as Gantt chart software or task management software, to help keep the project plan updated.

In addition, the project plan should consider the resources needed for its completion, such as personnel, equipment, and budget. It is important to ensure that the appropriate resources are available and are effectively assigned to ensure the completion of the project within the established timelines and budgets.

Schedule of activities

A schedule of activities is a planning tool used to show the tasks or activities that need to be completed in a project and their estimated duration. It is graphically represented in a bar chart, where each bar represents a task and its length represents its duration. The schedule also includes information about the sequence of tasks and the estimated start and end dates.

The objective of the project schedule is to help project management visualize and understand the project scope, the interdependencies between tasks, the delivery deadlines, and the necessary resources. It also helps identify and manage potential delays or issues that may arise during the project.

To design a project schedule, it is necessary to follow the following steps:

  1. Identify project activities: A breakdown of all the necessary tasks to complete the project must be performed. It is important to note that these activities must be specific and measurable to be included in the schedule.
  2. Estimate the duration of each activity: Once the activities have been identified, the time it will take to complete each one must be estimated. It is important to be realistic in these estimates and consider factors such as the complexity of the task, the necessary resources, and dependencies between activities.
  3. Define dependencies between activities: Some activities may depend on the completion of others, so it is important to define these dependencies in the schedule to ensure that they are planned in the correct order.
  4. Create a network diagram: A network diagram can be used to visualize dependencies between activities. This will help identify the critical path of the project and the activities that have a greater influence on the final deadline.
  5. Assign resources: Identify and assign the necessary resources for each activity, such as people, equipment, and materials. This will help ensure that the necessary resources are available to complete the activities as planned.
  6. Create the schedule: Using the information collected in the previous steps, a detailed project schedule can be created. This can be a table or a Gantt chart that shows the start and end dates of each activity, as well as the important milestones of the project.

It is important to note that the schedule is a dynamic tool that can change as the project progresses. Therefore, regular monitoring of the project's progress is necessary and the schedule should be updated as necessary to ensure that the project is moving in the right direction.

Here is an example of a schedule with task dependencies:


In this example, tasks are organized in sequential order, and each task has a duration in days. The "Predecessors" column shows the tasks that must be completed before a particular task can begin.

The horizontal line in each row shows the duration of the task, and the "Start" and "End" columns indicate when the task is expected to start and end. Progress bars can also be added to indicate the actual progress in each task.

It's important to note that a project schedule can be more complex than this example, particularly for larger and more complicated projects. The representation of dependencies between tasks is an important part of schedule design to ensure the project is completed efficiently and effectively.

Gantt Chart

The Gantt chart is a graphical tool that allows visualizing the tasks of a project and their progress over time. It is used to plan, schedule, and control the tasks and resources of a project.

It consists of a series of horizontal bars that represent each task of the project and its planned duration. Each bar starts at the start date of the task and ends at the planned end date. The bars can be color-coded to represent different types of tasks or to indicate their current status (in progress, completed, delayed, etc.).

In addition, the Gantt chart can include information about the assignment of resources to each task and the dependencies between tasks. Dependencies are shown by arrows that connect the bars of the tasks. For example, if task B depends on task A, an arrow connecting the bar of task A to the bar of task B will be drawn.

Gantt chart

By using a Gantt chart, the project team can quickly identify critical tasks and the interdependencies between them. Slack or time margins between tasks can also be identified, allowing the project schedule to be adjusted if necessary.

There are many software programs for creating this type of chart, such as Microsoft Project, GanttProject, Smartsheet, and many others. These programs allow easy modification of the project schedule, updating task dates and duration, and adding or removing tasks and resources.

Schedule of activities VS Gantt chart

A schedule and a Gantt chart are project planning tools that show the tasks and activities to be performed in a project on a timeline. Although they are often used interchangeably, there are some differences between the two.

A schedule is a visual representation of a project over time, showing the start and end dates of each task and its duration. A schedule can be presented in a simple table, with a list of tasks in chronological order and their corresponding dates, or in a more complex diagram with horizontal bars showing the duration of each task and their interdependence.

On the other hand, a Gantt chart is a project management tool that shows project tasks on a horizontal timeline and uses bars to represent the duration of each task. Additionally, the Gantt chart also shows task dependencies and project deadlines.

In summary, a schedule is a planning tool that shows the start and end dates of each task, while a Gantt chart is a project management tool that shows the duration of each task and its dependencies. Although both are useful for planning and managing projects, the Gantt chart is more detailed and is more commonly used in complex projects.
