Crashing

A Develop Schedule Process, tool/technique is Schedule Compression. This is a Schedule Compression variation is never initiated by the PM and looks at cost and schedule trade-offs. It adds resources to the critical path tasks or requires extra hours or effort from existing resources. It often leads to increased risk and cost.

Program Evaluation and Review Technique (PERT)

A Develop Schedule tool/technique is a Schedule Network Analysis. This variation was developed by the US Navy in the 1950s to evaluate the project schedule and forecast the probability of on time completion. It is similar to the Critical Path Method (CPM) except the CPM uses the most likely duration of activities and this uses the weighted average expected value to determine activity durations.

bar chart

A project schedule type that represents activities in bars across a timeline. Also called a Gantt chart.

Gantt chart

A project schedule type that represents activities in bars across a timeline. Also called a bar chart. (2 words)

program evaluation and review technique (PERT)

A schedule network analysis technique that uses weighted averages in computing Expected Values to determine the activity/project duration. For each activity, the optimistic, 4xmost likely, and pessimistic duration is averaged for a weighted average. If desired the standard deviation can be determined to calculate early and late start and finish dates for each activity.

reverse resource allocation scheduling

A technique to optimize resources that assigns activities starting with the the project end date and proceeding backward through the schedule. It is used when specific resources are needed at certain times in the project. (4 words)

Deliverable

A unique or verifiable product or result that must be produced or performed in order to consider the project or phase complete. (1 word)

Estimate Activity Resources

Activity Resource Requirements and Resource Breakdown Structure are outputs of this process.

resources

All the people, equipment, materials, supplies, software, hardware, etc. used by the project.

resource based method

Also known as resource leveling, this is used when resources are over allocated, are only available at certain times, or when they are assigned to more than one activity at a time. The project manager attempts to balance out the resource assignments by adjusting activity dates, or assigning more tasks to resources that are underutilized, etc. The critical path may change and the project delivery may change with this method.

float time

Also known as slack time this is the amount of time you can delay the start of a task without delaying the end of the project (total) or the amount of time you can delay the start of a task without delaying the successor task (free). Total and Free are the two types. (2 words)
