When tasks must be completed one after another, they are referred to as what?

Tasks that must be completed one after another are referred to as sequential tasks. This implies a clear linear progression where the completion of one task is a prerequisite for starting the next. In project management and systems analysis, recognizing which tasks are sequential is crucial for effective planning and resource allocation.

Sequential tasks help teams identify dependencies and timelines, thus allowing for more accurate scheduling. When tasks are defined as sequential, it is understood that they cannot be worked on simultaneously, leading to better risk management and prioritization of workflow. This concept is essential for ensuring that each phase of work is completed in the proper order, avoiding potential bottlenecks that could arise from trying to tackle tasks out of sequence.

In contrast, other types of tasks—concurrent tasks occur simultaneously, independent tasks do not rely on one another, and dependent tasks emphasize a relationship between tasks—do not fit the description of needing to be completed in a strict order.
