Project Schedule
“Project Schedule” is an output for the process “Develop Schedule”.
The outputs from a schedule model are schedule presentations. The project schedule is an output of a schedule model that presents linked activities with planned dates, durations, milestones, and resources. At a minimum, the project schedule includes a planned start date and planned finish date for each activity. If resource planning is done at an early stage, then the project schedule remains preliminary until resource assignments have been confirmed and scheduled start and finish dates are established. This process usually occurs no later than the completion of the project management plan. A target project schedule model may also be developed with a defined target start and target finish for each activity. The project schedule presentation may be presented in summary form, sometimes referred to as the master schedule or milestone schedule, or presented in detail. Although a project schedule model can be presented in tabular form, it is more often presented graphically, using one or more
of the following formats, which are classified as presentations: – Bar charts. These charts, also known as Gantt charts, represent schedule information where activities are listed on the vertical axis, dates are shown on the horizontal axis, and activity durations are shown as horizontal bars placed according to start and finish dates. Bar charts are relatively easy to read, and are frequently used in management presentations. For control and management communications, the broader, more comprehensive summary activity, sometimes referred to as a hammock activity, is used between milestones or across multiple interdependent work packages, and is displayed in bar chart reports. An example is the summary schedule portion of Figure 6-21 that is presented in a WBSstructured
format.
– Milestone charts. These charts are similar to bar charts, but only identify the scheduled start or completion of major deliverables and key external interfaces. An example is the milestone schedule
portion of Figure 6-21.
– Project schedule network diagrams. These diagrams are commonly presented in the activity-on-node diagram format showing activities and relationships without a time scale, sometimes referred to as a pure logic diagram, as shown in Figure 6-11, or presented in a time-scaled schedule network diagram format that is sometimes called a logic bar chart, as shown for the detailed schedule in Figure 6-21.These diagrams, with activity date information, usually show both the project network logic and the project?s critical path schedule activities. This example also shows how each work package is planned as a series of related activities. Another presentation of the project schedule network diagram is a time-scaled logic diagram. These diagrams include a time scale and bars that represent the duration of activities with the logical relationships. It is optimized to show the relationships between activities where any number of activities may appear on the same line of the diagram in sequence.

“Project Schedule” is an input for the process “Control Schedule”.
Project schedule refers to the most recent version with notations to indicate updates, completed activities, and started activities as of the indicated data date.
“Project Schedule” is an input for the process “Estimate costs”.
The type and quantity of resources and the amount of time which those resources are applied to complete the work of the project are major factors in determining the project cost. Schedule activity resources and their respective durations are used as key inputs to this process. Estimate Activity Resources (Section 6.4) involves determining the availability of staff, the number of staff hours required, and quantities of material and equipment needed to perform schedule activities. It is closely coordinated with cost estimating. Activity duration estimates will affect cost estimates on any project where the project budget includes an allowance for the cost of financing (including interest charges) and where resources are applied per unit of time for the duration of the activity. Activity duration estimates can also affect cost estimates that have time-sensitive costs included in them, such as union labor with regularly expiring collective bargaining agreements or materials with seasonal cost variations.
“Project Schedule” is an input for the process “Determine budget”.
The project schedule includes planned start and finish dates for the project?s activities, milestones, work packages, and control accounts. This information can be used to aggregate costs to the calendar periods in which the costs are planned to be incurred.
“Project Schedule” is an input for the process “Plan Procurement management”.
Project schedule contains information on required timelines or mandated deliverable dates.
