What information does not help Drew calculate task duration?

To understand why the time people start working each day does not assist in calculating task duration, it's important to recognize what factors are directly related to determining how long a task will take to complete.

Task duration is primarily influenced by the scope of work, previous task durations, the expected end date, and the resources available for the task. These factors provide a framework for estimating how long a task is likely to take.

The expected end date of tasks offers a target that can guide the start and completion timelines. Previous task duration records provide historical insights that can aid in better forecasting the time required for similar future tasks. Available resources, such as the number of people working and their skill levels, directly affect how quickly or efficiently tasks can be completed.

In contrast, knowing what time individuals start working each day does not inherently contribute to understanding how long the entire task will take. Task duration calculation is more focused on overall work volume, resource availability, and past performance rather than specific daily start times. Hence, while start times can impact scheduling, they do not provide crucial information for estimating the total length a particular task will require.
