A project manager provided the team with a summary Gantt chart for the project. The team, however, has expressed interest in seeing the sequencing between all of the tasks. Which of the following should the project manager provide?
To show sequencing between all tasks (i.e., predecessor/successor relationships and dependency flow), the PM should provide a project network diagram. A summary Gantt chart is great for high-level timelines and major bars, but it can hide the detailed dependency logic that explains why tasks occur in a particular order and how delays propagate. In the CompTIA Project+ objectives, “Project network diagram” is explicitly listed among the key tracking charts/diagrams used to inform project decisions (alongside Gantt and milestone charts).
The other choices don’t match the need. A fishbone (Ishikawa) diagram is a root-cause analysis tool for quality issues, not for schedule dependencies. A burndown chart is used mainly in Agile to show remaining work over time, not task-to-task sequencing. A milestone chart highlights key dates, but it doesn’t show the detailed dependency chain between tasks.
So, to satisfy the team’s request for full sequencing visibility, the PM should share a project network diagram.
