Schedule with Network
authorized work within the various types of packages (i.e. Work Packages,
Planning Packages, and SLPP) should be scheduled in a manner that describes the
sequence of work and identifies significant task interdependencies.
authorized work facilitates effective planning, status, and forecasting, all of
which are critical to the success of projects.
The integration of the technical scope, schedule,
and cost aspects of the project results in:
more informed and expected sequence of work.
understanding of significant (or even overlooked/unexpected) interdependencies between work packages and
planning packages that determine total work time and critical path through the
Time-phasing of authorized discrete packages are
the building blocks of developing
the Performance Measurement Baseline.
Master schedule requirements should be extended to detailed
supporting schedules as necessary to effectively plan and manage the project. Depending
on the project size and complexity, lower level detailed schedules are needed
to be maintained as separate entities or integrated with the master schedule in
a single schedule. The basic principle is that all lower level (detailed)
schedules should support the Master Schedule requirements (e.g. Control
Accounts) and provide for project interdependencies as necessary.
Supporting plans, including detail schedules and budgets, are
subsequently developed, maintained and progressed as necessary during the
execution phase of the project. Contract/subcontract and critical procurement schedule requirements should be aligned with
the overall Master Schedule. It is important to plan and track all critical
schedule requirements that may constrain the successful conclusion of
2.3.5 Schedule Traceability
Schedule traceability is the
ability to track schedule dates, durations, and statuses at all levels of
detail. Traceability is used when integrating different schedules to a same
level of detail. Two types of traceability exist, namely vertical, and
Vertical traceability is used to
identify the relationships between different levels of project detail, such as
activities, work packages, and Control Accounts. Vertical traceability ensures
that work package durations are within the schedule dates of the overall
Control Account. It further ensures that Control Accounts in supporting
schedules will support the Master Schedule of the project.
