An independent task is a task that does not rely on other activities, and no other activities rely on this task completing. An independent task can be performed at any time during the project, as long as it meets the project objectives and requirements. An independent task has no dependencies or constraints with other tasks. An analysis task is a task that involves examining, evaluating, and interpreting information to identify and understand the problem, need, or opportunity. An analysis task may rely on other activities, such as elicitation, documentation, or validation, and other activities may rely on this task completing, such as design, development, or testing. An analysis task may have dependencies or constraints with other tasks. A predecessor task is a task that must be completed before another task can start or finish. A predecessor task has a logical or sequential relationship with another task, which is called a successor task. A predecessor task may affect the start or end date, duration, or resources of the successor task. A dependent task is a task that relies on another task to start or finish. A dependent task has a logical or sequential relationship with another task, which is called a predecessor task. A dependent task may be affected by the start or end date, duration, or resources of the predecessor task. References: CBAP® Handbook, CBAP® Exam Prep Study Guide, Project Management Institute
