What describes the difference between defining activities and sequencing activities?

• A. Define activities estimates durations; sequence activities determines dependencies.
• B. Define activities breaks down the work into specific tasks; sequence activities determines the order and dependencies among those tasks.
• C. Define activities creates the project schedule; sequence activities identifies milestones.
• D. Define activities analyzes risk; sequence activities communicates with stakeholders.

Answer: (B)

Defining activities is about breaking the project work into concrete, specific tasks that will deliver the project’s outputs. It answers what exactly needs to be done and results in a detailed list of activity descriptions and attributes. Sequencing activities uses that list to determine the order and the dependencies between tasks. It answers in what sequence those tasks should be performed and how they relate to each other—what must finish before another can start, what can run in parallel, and where lag or lead times might apply. For example, in a construction project you would first define activities like site clearing, laying foundations, framing, and roofing. Sequencing then decides that site clearing and foundation work must occur before framing, and that some tasks could overlap if they’re independent. This separation explains why the two steps are distinct: one defines the what, the other defines the when and how they connect. Other options mix in estimating durations, creating the schedule, identifying milestones, or handling risk and stakeholder communication, which are different activities within project planning. The key difference here is that defining activities focuses on identifying the tasks themselves, while sequencing activities focuses on the order and dependencies among those tasks.
