-
time management processes
define activities, sequence activities, estimate activity resources, estimate activity durations, develop schedule, control schedule
-
integration management
the process in which the schedule management plan is created
-
define activities outputs
process outputs include: activity list, activity attributes, and milestone list
-
sequence activities outputs
process outputs include: network diagrams and project document updates
-
estimate activity resources outputs
process outputs include:activity resource requirements and resource breakdown structure
-
estimate activity durations outputs
process outputs include: activity duration estimates and project document updates
-
develop schedule outputs
process outputs include: project schedule and schedule baseline
-
develop schedule process
the actions and tools necessary to create a bought into, approved, realistic, and formal project schedule
-
control schedule outputs
process outputs include: work performance measurements and change requests
-
mandatory dependencies
dependencies where one activity must be done after or before another
-
discretionary dependencies
dependencies where the project manager prefers activities to be accomplished in a certain order
-
hard logic
another term for mandatory dependencies
-
soft logic
another term for discretionary dependencies
-
external dependencies
dependencies based on the needs of a party outside the project
-
resource breakdown structure
an organizational chart or table showing identified resources by category
-
critical path
the longest path through the network diagram. It shows the project manager the shortest time in which the project can be completed. It also shows the project manager where to focus his or her time it is used in compressing or adjusting the schedule
-
near-critical path
the path closest in length to the critical path
-
lag
waiting time inserted into the schedule
-
total float
amount of time an activity can be delayed without delaying the project
-
total float formula
late start - early start or late finish - early finish
-
free float
the amount of time an activity can be delayed without delaying the early start date of its successor
-
project float
the amount of time the project can be delayed without affecting the project's required end date. The desired project end date minus the actual end date
-
methods to compress a schedule
crashing and fast tracking
-
crashing
schedule compression through analyzing cost and schedule trade-offs to obtain the greatest compression for the least cost while maintaining scope
-
fast tracking
schedule compression by doing more critical path activities in parallel
-
critical chain method
a schedule network analysis tool that makes use of buffers
-
reestimating
estimating the project again after planning to make sure you can still meet the end date, budget, or other objectives
-
resource leveling
keeping the amount of resources used for each time period constant, thus affecting the project duration
-
schedule baseline
the approved schedule with any approved changes, used to measure project schedule performance
-
main tools for displaying a schedule
network diagrams, bar charts, and milestone charts
-
network diagram
shows inter-dependencies between activities and how project activities will flow from beginning to end. It may also be used to determine the critical path
-
simple bar chart
shows project schedule or project status
-
milestone chart
shows high-level project status
-
Monte Carlo analysis
a schedule network analysis technique. It is used to simulate the project to determine how likely you are to get the project completed by any specific date or for any specific cost. It is also used in the perform quantitative risk analysis process to determine an overall level of risk on the project.
-
50/50 rule
method of progress reporting where 50 percent of the effort is reported complete when an activity begins. The balance is recorded only when an activity is finished.
-
20/80 rule
method of progress reporting where 20 percent of the effort is reported complete when an activity begins. The balance is recorded only when an activity is finished.
-
0/100 rule
method of progress reporting where 0 percent of the effort is reported complete when an activity begins. The balance is recorded only when an activity is finished.
