Chapter 7 – Scheduling Resources and Budgets

7.9. In-depth Look: Gantt Charts

In-depth Look

While grappling with the problem of tracking different tasks and activities in departments of governments during the war effort in 1917, Henry Gantt realized scheduling should be based on time and not quantities. A simple bar chart was the solution. In graphic form, management was enabled to show progress in their work and indicate where action could be taken and keep on time.

In the second decade of the 20th century, Gantt charts were created as a visual tool to show projects scheduled and actual progress and was named after Henry Gantt. The Gantt chart has been accepted as a project management tool in today’s world. The Gantt charts were used first on Hoover Dam’s large construction projects in 1931 and the interstate highway network in 1956 (Henry Gantt’s Legacy, n.d.). Today, Gantt chart tools are referred to as road map tools, and Gantt charts have become elaborate and complex with the use computers.

Gantt charts started as an effective mechanism for recording workers’ progress towards tasks. Each worker kept a daily chart. If it is in black, the standard was met; in red standard is not met. This expanded into the chart of others on the quantity of work per machine, per worker, cost, and control.

These blueprints were drawn by hand. The plan was less useful than it could have been because most projects are always changing. Now that computers and project management programs are available, it is easy to produce, update, and print Gantt charts. Gantt charts are the most common way to keep track of project schedules today. It is helpful to show information about activities, such as how tasks relate to each other, how long each task takes, what resources are needed, etc. (Duke, 2022).

Gantt charts can be used to plan and schedule projects. They help to figure out how long the project should take and what materials are need. It can help keep track of the relationships between tasks (Mindtools, n.d.). The project manager can see immediately what needs to be done by a certain date, and if the project is behind schedule, on time, or ahead of schedule.

Activities and schedules are shown on the graph, and it is easy to see where tasks, subtasks, and master tasks start in a project. It is easy to see dates and deadlines for tasks, and easy to see plans for the day, week, month, quarter, and year. This makes it simple to manage the project team and all the small tasks in a large project. It shows who is on the team, their job, and progress.

Gantt charts assist teams in planning work around deadlines and allocating resources effectively. They organize projects, enhance the overall visibility of the project, and keep everyone on track. Gantt charts clarify the project and team requirements by presenting tasks across a calendar and highlighting dependencies. Project managers use major milestones on potential risks Gantt charts to keep track of their projects (Team Gantt, 2022). They show, among other things, how the start and end dates of tasks fit together. Milestones and dependent tasks.

This will assist you in estimating the duration of a project, identifying the required resources, and organizing them in the order in which they will be completed perfectly. A horizontal bar chart is used in project management to represent a project plan’s progression visually. It provides structure and foresight for the execution phase, eliminating inefficient activities and patterns (Duke, 2022).

It is simple to schedule tasks, simple to comprehend, and provides a clear and visual representation of time frames. Gantt charts have disadvantages. Not all Gantt charts are perfect, and setup can be time-consuming and tedious (Duke, 2022). They can become complex and difficult to interpret for large projects. Or, sometimes, they have insufficient level of details.

Another method that may be utilised to comprehend the project is the Project Planning Timeline. This method is just as significant as the Gantt chart in that it helps to plan the project in the same way as Gantt charts. It is simpler to comprehend the project information and timeframes in one line (Lucid, 2022).

The Gantt Chart makes the Human Resource Department and project team processes easier by using the following steps (Duke, 2022):

  1. The project team and Human Resources should first outline its goals and determine the objectives.
  2. Human Resources can ensure they have enough resources to achieve the project goals and discuss with the team.
  3. Design the Gantt Chart. Tasks can be divided into smaller tasks to simplify completion. Example for Human Resources projects: tasks for hiring employees (advertise, receive applications, evaluation, interview, and selection).
  4. Human Resources can assess and help the team organize the tasks separated in the Step 3 and specify the completion time for each task with the project team.
