3 Schedule Planning and Control Free Online FlashCards

What does a finish-to-start relationship require?

A finish-to-start relationship means the successor cannot start until the predecessor finishes.

Which activities can proceed in parallel after requirements?

After requirements are defined, design and equipment ordering can proceed in parallel because both depend on requirements, not on each other.

What should inform an activity duration estimate?

Estimate duration from the activity’s scope, expected resources, working calendar, and relevant past performance. Record assumptions so the estimate’s conditions are clear.

What determines the critical path?

The critical path is the longest-duration path through the network; it determines the earliest possible project finish under the schedule’s logic and assumptions.

What does total float measure?

Total float is how long an activity can slip without delaying the forecast project finish.

How is earliest finish calculated in a forward pass?

For a forward pass, earliest finish is earliest start plus duration: $EF = ES + \text{duration}$.

How do predecessors determine a successor’s earliest start?

A successor’s earliest start is the latest earliest finish among its predecessors.

How does a backward pass calculate latest start?

In a backward pass, latest start is latest finish minus duration: $LS = LF - \text{duration}$. A predecessor’s latest finish is the earliest latest start among its successors.

Which path is critical in the example network?

In the example network, A–B–D–F–G is critical, with a total duration of $12$ working days.

How much total float does the example’s procurement path have?

The procurement path A–C–E–F–G has $1$ working day of total float in the example network.

What happens if equipment receipt slips by $2$ working days?

A $2$-working-day slip in equipment receipt uses its $1$ day of float and delays the project finish by $1$ working day. The procurement path becomes critical.

What is a schedule baseline?

The approved target schedule used to plan and measure performance is the schedule baseline. It reflects authorized scope, logic, durations, calendars, assumptions, and milestones.
