🔍 Guiding Question How can a business plan and coordinate a complex project with multiple tasks, teams, and deadlines — and how does visualising that plan change the quality of the decisions made?
🌍 Why This Matters When Apple prepares to launch a new iPhone, hundreds of parallel workstreams — hardware testing, software development, marketing campaigns, supply chain logistics, and retail training — must all converge on a single launch date. A Gantt chart is one of the core tools that makes that coordination visible, trackable, and manageable for project leaders across the organisation.
What Is a Gantt Chart?
Complex projects fail not because the individual tasks are too hard, but because the sequencing and timing of those tasks is poorly managed. A Gantt chart solves this by making the entire project visible on a single page.
📘 Gantt Chart A Gantt chart is a horizontal bar chart used in project management that displays all tasks or activities of a project against a timescale. Each bar represents one task; its position shows when the task starts and ends, and its length represents its duration. The chart allows managers to see which tasks run sequentially, which run simultaneously, and when the overall project should be completed.
🔗 Analogy: The Film Director's Schedule Think of a Gantt chart as the shooting schedule for a film. The director cannot film the final battle scene before the costumes are made, and the editing team cannot begin until at least some footage exists. The schedule shows every department what they must do, when, and how their work connects to everyone else's — exactly what a Gantt chart does for a business project.
Key Components of a Gantt Chart
Understanding each component is essential — exam questions frequently ask students to read, complete, or construct a chart from data, and marks are awarded for correctly labelling every element.
- Tasks / Activities: Listed vertically on the left-hand axis. Each row represents one distinct activity in the project (e.g. "market research", "product design", "staff training").
- Timescale: Shown horizontally across the top or bottom axis. Units are typically days, weeks, or months depending on project length.
- Duration bars:
