Here is a project management timeline for an e-commerce website upgrade, using a Gantt chart to schedule and track tasks. The chart is divided into sections representing different aspects of the site such as Customer Account, Shopping Site, Shopping Cart, and Testing. Each task is assigned a unique identifier, duration in days, and a specific timeframe for completion. Dependencies between tasks are marked, indicating that some tasks must be completed before others can begin. This type of visual representation is a common tool used in project management to provide a bird's eye view of a project’s progress and track individual components over time.
