Introduction to Scheduling

Large projects have very large number of stakeholders in the form of Owner, Project management consultants (PMC), Contractors, Sub-contractors. This can be again divided based on their disciplines like quality, procurement, engineering, risk etc.

If all these stakeholders are not using compatible tools and processes to create, status update and schedule revisions, roll up and down of the schedule from the lower levels to higher levels and vice-versa is not possible.

Schedule management is the process of planning, implementing, checking and acting on the compatibility of schedules and the integrity of the schedule data.
