Order the steps for developing a project schedule.
Drag steps to the numbered slots on the right, or tap a step then tap a slot.
Trap 1: Define activities, then estimate activity durations, then sequence…
This order is incorrect because "Sequence Activities" must logically precede "Estimate Activity Durations." Establishing the dependencies, logical relationships, and applying leads or lags through sequencing provides the necessary context for more accurate duration estimates. Without understanding how activities relate to each other and potential resource conflicts across parallel paths, duration estimates might be less reliable and fail to account for the overall project's logical flow and constraints, making the subsequent critical path determination flawed.
Trap 2: Sequence activities, then define activities, then estimate activity…
This sequence is fundamentally flawed because "Sequence Activities" cannot occur before "Define Activities." You must first identify and break down the work into discrete, manageable schedule activities before you can establish any logical relationships or dependencies between them. Attempting to sequence undefined or vaguely conceptualized activities would result in an incomplete, inaccurate, or impossible schedule network diagram, rendering all subsequent steps meaningless.
Trap 3: Define activities, then determine the critical path, then sequence…
This order is incorrect because "Determine the Critical Path" is a calculation performed on a fully developed schedule network, making it impossible to execute before "Sequence Activities" and "Estimate Activity Durations." The critical path analysis requires all activities to be logically linked with their dependencies (sequencing) and to have assigned durations (estimation). Without these foundational steps, there is no complete network diagram to analyze for the longest path, earliest/latest dates, or total float.
- A
Define activities, then sequence activities (including applying leads and lags), then estimate activity durations, then determine the critical path
This sequence accurately reflects the logical flow of schedule development processes as outlined in the Project Management Body of Knowledge (PMBOK® Guide). First, "Define Activities" breaks down work packages into manageable schedule components. Then, "Sequence Activities" establishes the logical relationships and dependencies between these activities, including applying necessary leads or lags. Subsequently, "Estimate Activity Durations" calculates the time required for each activity, considering resources and constraints, which then allows for the final step, "Determine the Critical Path," to identify the longest path through the project network and the minimum project duration.
- B
Define activities, then estimate activity durations, then sequence activities, then determine the critical path
Why wrong: This order is incorrect because "Sequence Activities" must logically precede "Estimate Activity Durations." Establishing the dependencies, logical relationships, and applying leads or lags through sequencing provides the necessary context for more accurate duration estimates. Without understanding how activities relate to each other and potential resource conflicts across parallel paths, duration estimates might be less reliable and fail to account for the overall project's logical flow and constraints, making the subsequent critical path determination flawed.
- C
Sequence activities, then define activities, then estimate activity durations, then determine the critical path
Why wrong: This sequence is fundamentally flawed because "Sequence Activities" cannot occur before "Define Activities." You must first identify and break down the work into discrete, manageable schedule activities before you can establish any logical relationships or dependencies between them. Attempting to sequence undefined or vaguely conceptualized activities would result in an incomplete, inaccurate, or impossible schedule network diagram, rendering all subsequent steps meaningless.
- D
Define activities, then determine the critical path, then sequence activities, then estimate activity durations
Why wrong: This order is incorrect because "Determine the Critical Path" is a calculation performed on a fully developed schedule network, making it impossible to execute before "Sequence Activities" and "Estimate Activity Durations." The critical path analysis requires all activities to be logically linked with their dependencies (sequencing) and to have assigned durations (estimation).
