Term

Definition
- The Critical Path, the longest necessary path through a network of activities when respecting their interdependencies
- To find critical path sum the durations of each path and the path with the largest total duration is the critical path
- The critical path always has a float of zero (0) |

| Activity on Node vs. Activity on path |

Definition
| Counting up numbers on nodes vs counting up numbers on path but same result |
|
|
Term
|
Definition
Longest sequence of activities in a project plan which must be completed on time for the project to complete on due date. An activity on the critical path cannot be started until its predecessor activity is complete; if it is delayed for a day, the entire project will be delayed for a day unless the activity following the delayed activity is completed a day earlier.
- The line of project activities having the least float, especially when float is close to, or below zero (important). |
|
|
Term
|
Definition
| Is the earliest time that an activity can start. An activity near the end of the path will only start early if all of the previous activities in the path also started early. If one of the previous activities in the path slips, that will push it out. Tasks can be performed within a reasonable time. The industry “80 hour rule” states that a work task should be completed in two weeks (or less) |

Definition
Is the earliest time that an activity can finish. It’s the date that an activity will finish if all of the previous activities started early and none of them slipped.
The ES (early start) of the first activity in the path is 1. The EF (early finish) of any task is its ES plus its duration minus one. |

| he latest time that an activity can start. If an activity is on a path that’s much shorter than the critical path, then it can start very late without delaying the project – but those delays will add up quickly if other activities on its path also slip! |

| Is the latest time that an activity can finish. If an activity is on a short path and all of the other activities on that path start and finish early, then it can finish very late without causing the project to be late. |

Definition
| Is the time by which an activity can be delayed without delaying the early start of its successor. TIP: Unless specifically asked for FF on exam…consider float =TF |

Term
|
Definition
| The ES (early start) of the first activity in the path is 0. The EF (early finish) of any task is its ES plus its duration. For Successor tasks: ES= EF of predecessor. If more than one predecessor take the largest EF. This is included in the process of Computing Early Start (ES) |
|
|
Term
|
Definition
- The LF (early start) of the Last activity in the path = EF . The LS (Late Start) of any task is its LF minus its duration. So start with Activity H. It’s the Last in the path, so LF = EF, and EF .
For Predecessor tasks: LF= LS of successor. If more than one predecessor take the smallest LS.
- LS=LF – Duration
- Float= ES-LS or EF-LF
- Slack = Float
This is a part of Computing Late Finish |

Term
|
Definition
- Parametric: uses statistical techniques to evaluate the relationship between historical or other data to calculate an estimate for activities such as cost, budget, time, duration
- Analagous: Uses parameters such as duration or budget from a previous similar project as the basis for estimating same parameter on current project.
- Reserve Analysis: Contingency reserves based on percentage of activity duration, fixed number of work periods or using statistical methods. |

Definition
Improves accuracy by considering estimation uncertainty and risk
- Most likely estimate (tM) given the resources that are to be assigned, their productivity, realistic expectations, dependencies on other resources.
- Optimistic estimate (to) based on “best case scenario”
- Pessimistic estimate (tp) based on “worst-case” scenario
FORMULA : tE = to + 4tM + (tp) |

Definition
- The bar in each row identifies the corresponding task
- The horizontal position of the bar identifies start and end times of the task
- Bar length represents the duration of the task
- Task durations can be compared easily
- Good for allocating resources and re-scheduling
- Precedence relationships can be represented using arrows
- Critical activities are usually highlighted
- Slack times are represented using bars with doted lines
- The bar of each activity begins at the activity earliest start time (ES)
- The bar of each activity ends at the activity latest finish time (LF). |

Definition
| Phases or activities normally performed in sequence are performed in parallel. May result in rework or increased risk. Only works if activities can be overlapped to shorten the duration. |

Term

Definition
| Trade-offs between cost and schedule are analyzed to determine how to obtain the greatest amount of compression for the least incremental cost. Crashing only works where adding additional resources will shorten the duration. Not always viable. This a part of Schedule Crashing |

- Network diagrams are the preferred technique for showing activity sequencing
- A network diagram is a schematic display of the logical relationships among, or sequencing of, project activities
