Study Notes

Project Management Formulas and Concepts

Total Float (TF) formula: Not provided in the original text, but it is typically calculated as TF = LF - EF, where LF is the latest finish time and EF is the earliest finish time.
Parkinson's Law: Refers to the idea that "work expands to fill the time available for its completion".

Standard Deviation and Time Estimates

Standard Deviation (σ) formula using three time estimates (a, m, b): σ = (b - a) / 6
TE = $(a + 4m + b) / 6 represents a method to estimate the expected time for a task.

Network Diagrams and Scheduling

AON Network: Primarily used to create a visual representation of a project schedule.
Gantt Chart: A type of bar chart that illustrates a project schedule. Advantage: provides a clear visual representation of the project timeline.
Disadvantage of Gantt Chart: Can be cumbersome to create and update manually.

Critical Path and Float

Critical Path: Represents the sequence of activities that determines the minimum duration required to complete a project.
Slack (Float): Refers to the amount of time an activity can be delayed without affecting the overall project duration.

Project Management Tools and Techniques

Precedence Diagramming Restrictions: Define the relationships between activities in a project.
PERT and CPM: Two popular project management techniques developed in the late 1950s.
CPM and PERT: Stand for Critical Path Method and Program Evaluation and Review Technique, respectively.
PERT was developed for the Polaris missile/submarine project in 1958.

Project Management Fundamentals

A project: Comprises a series of connected activities and events.
Activity: A specific task or set of tasks that are required by the project, use up resources, and take time to complete.
Immediate Predecessor: The activity that must be completed before another activity can begin.
Network Scheduling: Advantage: allows for the creation of a realistic project schedule.
Henry L. Gantt: Developed the Gantt chart.
Basis for monitoring a project: The project schedule and budget.
Resource allocation: Can be planned using a Gantt chart, which shows when resources are needed.
