What is the main difference between concurrent and sequential tasks in scheduling?

• A. Concurrent tasks must be completed in a specific order
• B. Sequential tasks can be performed simultaneously
• C. Concurrent tasks can be performed simultaneously
• D. Sequential tasks are easier to manage

Answer: (C)

The main difference between concurrent and sequential tasks in scheduling lies in the ability to perform tasks simultaneously. Concurrent tasks are those that can occur at the same time, allowing for more efficient use of time and resources. This characteristic enables project managers to optimize schedules by overlapping activities that do not depend on each other, potentially leading to shorter overall project durations. In contrast, sequential tasks must follow a specific order; one task cannot begin until the previous one is completed. This sequential nature can limit flexibility in the schedule and may lead to longer project timelines, as each task is dependent on the completion of its predecessor. Understanding this distinction is crucial for effective project management, as it informs how to structure schedules to make the best use of available resources and time.
