What is NOT important when defining timelines?

When defining timelines, the impact of each outcome is NOT directly important. Timelines are about scheduling and sequencing tasks, focusing on when things happen and how long they take. The impact of an outcome is crucial for prioritizing tasks and understanding their value, but it doesn't dictate the duration or sequence of the tasks themselves. Dependencies are critical because they determine the order in which tasks must be completed. Knowing how long each task takes is fundamental for estimating the overall project duration and allocating resources effectively.
