What is the difference between an intermediate schedule and a detailed schedule?

• A. Intermediate schedules tie, or roll up, the detailed tasks in the detailed schedules to key events and milestones in the summary schedule(s); whereas detailed schedules graphically depict the effort at the work package and planning package level.
• B. Intermediate schedules show all tasks in detail; detailed schedules show milestones only.
• C. Intermediate schedules are used for external reporting; detailed schedules are for internal planning.
• D. Intermediate schedules are created after the project baseline; detailed schedules are created before.

Answer: (A)

Focus on the level of detail and how schedules serve different audiences. A detailed schedule lists every task within each work package and planning package, with durations, sequences, dependencies, and assigned resources. An intermediate schedule, by contrast, consolidates those tasks and ties them to key events and milestones in a higher-level summary schedule. In other words, the intermediate view rolls up the granular work to milestone dates, while the detailed schedule graphically shows the effort at the work package and planning package level. This matters because management can monitor progress against major milestones without being overwhelmed by every tiny task, while the team uses the detailed schedule to plan and execute the work.
