A procedural plan that indicates the time and sequence of each operation. In construction, a schedule is most often used to deterministically set milestones and completion dates for tasks and to monitor progress against those dates. Schedules are thereby are inherently unreliable when coordinating activities because projects are not deterministic endeavors.
In Project Production Management, schedules result from the analysis of capacity utilization, variability, WIP and their associated control as governed by Operations Science.
