HKSM

The compiled set of details that define the schedule and support its monitoring, management, and control.

Key Points

• Includes items such as activity attributes, sequencing details, calendars, resource needs, assumptions, constraints, and milestone lists.
• Feeds the schedule model and supports baseline creation, change control, and performance tracking.
• Is maintained and updated as estimates, progress, and risks evolve throughout the project.
• Enables reporting, forecasting, and what-if analysis for informed decision-making.

Example

On an ERP rollout, the project manager maintains schedule data including task IDs and descriptions, predecessor and successor links, resource calendars, non-working days, milestone dates, and constraints. When a key tester becomes unavailable, the PM updates the schedule data and runs a what-if analysis to re-sequence testing without slipping the go-live date.

PMP Example Question

Which artifact typically contains activity attributes, logical relationships, calendars, assumptions, and constraints used to build and control the project schedule?

1. Schedule baseline
2. Schedule data
3. Project charter
4. Work performance information

Correct Answer: B — Schedule data

Explanation: Schedule data is the repository of detailed information used to define, manage, and control the schedule. The schedule baseline is the approved plan, the charter authorizes the project, and work performance information summarizes results and variances.
