For contractors

Prepare Baseline Schedule

A baseline may be one source for assessing planned work and later events. The submission and review history, updates, actual performance and contract-administration record can inform its relevance to a particular question.

Schedule detail and logic affect what a schedule can show. Constraints and duration assumptions affect the calculation. A limitation in one area is assessed for its significance to the question; it does not make the rest of the project record disappear.

Working calendars, seasonal conditions, weather assumptions and exposed work may affect planned durations and the meaning of a schedule forecast. Their significance depends on the project facts, records and administration of schedule submissions and reviews.

The level of detail, resource assumptions, access conditions and available production information affect how a schedule represents the work. Those considerations are evaluated in the project context rather than by a single prescribed level of detail or production source.

Constraints can affect calculated dates, float and critical-path results. Analysts may consider their purpose, placement and effects in relation to the project, contract and selected analytical approach.

Possible assignment considerations

In practice

  1. 01

    Consider the contract context

    The relevant contract provisions, project context and scheduling questions affect how a baseline is prepared or evaluated. The significance of a particular submission depends on those circumstances.

  2. 02

    Build the work breakdown

    What activity structure and coding reflect the way work, progress, payment and project-management roles are recorded on this project?

  3. 03

    Model the real sequence

    Constraints can affect calculated dates, float and critical-path results. Analysts may consider their purpose, placement and effects in relation to the project, contract and selected analytical approach.

  4. 04

    Consider calculations and assumptions

    Which calculated dates, logic, float and assumptions are relevant to the purpose of the schedule and its supporting explanation?

Considerations and limitations

Questions and limitations to consider

The submittal-driven baseline

Schedule detail and logic affect what a schedule can show. Constraints and duration assumptions affect the calculation. A limitation in one area is assessed for its significance to the question; it does not make the rest of the project record disappear.

Constraints standing in for logic

Constraints can affect calculated dates, float and critical-path results. Analysts may consider their purpose, placement and effects in relation to the project, contract and selected analytical approach.

Durations nobody owns

The level of detail, resource assumptions, access conditions and available production information affect how a schedule represents the work. Those considerations are evaluated in the project context rather than by a single prescribed level of detail or production source.
