In Adobe Workfront, two common reasons a task cannot be marked Complete are incomplete enforced predecessors and incomplete subtasks on a parent task. Adobe documentation explains that when a predecessor is enforced , Workfront does not allow the successor task to be marked In Progress or Complete until the predecessor task is completed. Therefore, if the predecessor task is still In Progress , it can block the current task from being closed, provided the predecessor relationship is enforced. Adobe also explains that parent tasks cannot be updated to Complete when the project’s Summary Completion Mode is set to Automatic and the subtasks are not completed. This means incomplete child tasks can prevent the parent task from closing. Being a predecessor to another task does not stop the current task from being completed. Assignment to a job role rather than a named user does not inherently prevent completion, and an Active project status is normal for work execution. Therefore, the correct answers are A and B .

In Adobe Workfront, Scrum supports this hybrid approach because teams can keep structured project planning in Workfront while managing selected tasks as agile stories within iterations, commonly called sprints. Adobe documentation explains that Scrum teams use a backlog and then plan an iteration by selecting tasks or issues from that backlog. Adobe also notes that many organizations use the words sprint and iteration interchangeably, and that iteration planning occurs after the backlog has been groomed and prioritized. This allows planned project tasks to remain part of a Workfront project while the team manages execution through sprint-based agile practices. Waterfall is structured and sequential, but it does not provide sprint-based task management. Kanban provides flexible visual flow through a board, but it is not centered on fixed sprint or iteration planning. Therefore, the Workfront methodology that combines structured planning with sprint flexibility is A. Scrum .

When a user updates the Commit Date to a date later than the original planned date in Adobe Workfront, the Planned Completion Date of the task is automatically updated to reflect the new commit date. This feature ensures that the timeline is adjusted based on the most current commitment by the task assignee, which can then impact downstream tasks and the overall project schedule.

This change streamlines project planning and helps keep task dependencies aligned with realistic completion expectations​​.
