Name the four types of logical relationships

1 Finish to start 2 Start to finish 3 Start to start 4 Finish to Finish

Network Diagram

A depiction of project activities and the interrelationships between these activities.

Activity List

A list of all the activities required to complete the work of the project that also includes an identifier code and the WBS code it is associated with. Activites are broken down from the work package level of the WBS

Explain a network diagram

A network diagram is used to depict project activities and the interrelationships and dependencies among these activities.

Precedence diagramming method PDM

A network diagramming method that places activities on nodes, which connect to dependent activities using arrows. Also known as activity on node

Name the two major relationships between dependent tasks

A predecessor is a task that exists on a path with another task and occurs before the task in question. A successor is a task that exists on a common path with another task and occurs after the task in question.

Finsh to Start

A project task relationship in which the scuccessor task cannot begin until the predecessor task has completed

Finish to Finish

A project task relationship of the successor task is dependent on the finish of the predecessor task

Start to Start

A project task relationship where the start of the successor task depends on the start of the predecssor task

Fast Tracking

A schedule compression technique where two activities that were previously scheduled to start sequentially start at the same time. Fast tracking reduces schedule duration.

Critical Path Method CPM

A schedule development method that determines a single early and late start date, early and late finish date, and the float for each activity on the project

Start to finish

A task relationship where the finish of the successor task is dependent on the start of its predecessor

External dependency

A type of dependency where a realtionship between a project task and a factor outside the project, such as weather conditions, drives the scheduling of that task

Mandatory Dependency

A type of dependency where the relationship between two tasks is created by the type of work the project requires

Analogous estimating

An estimating technique that uses the actual duration of a similar, completed activity to determine the duration of the current activity. This is also called top down estimating

Activity Duration

Assessing the number of work periods needed to complete the project activities. Work periods are usally expressed in hours or days. Large projects might express druation in weeks or months

Program Evaluation and Review Technique PERT

Calculates the expected value or weighted average, of critical path tasks to determine project duration by usines three estimates; most likely, pessimistic, and optimistic. The PERT calculation is (Optimistic+pessimisstic+(4 x most likely))/6

Define the purpose of CPM

Critical Path Method calculates the longest full path in the project. This path controls the finish date of the project. Any delay to a critical path task will delay the completion date of the project.

Know and understand the three most commonly used techniques to estimate activity duration

Expert judgment relies on the knowledge of someone familiar with the tasks. Analogous or top down esimating bases the estimate on similar activities from a previous project. Parametric estimates are quantitatively based estimates that typically calculate the rate times the quantity.

Name the three most common ways project schedules are displayed

Project schedules are typically displayed as milestone charts, PERT network diagrams, or Gantt Charts; a Gantt chart is a type of bar chart

Define Qualtiy gates and Governance Gates

Quality gates are used to check the work, and governance gates are used as client sign offs, managment approvals, and legislative approvals.

Describe the sequencing process

Sequencing is the process of identifying dependency relationships between the project activities and scheduling activities in the proper order

Float Time

The amount of time the early start of a task may be delayed without delaying the finish date of the project. Also known as slack time

Logical Relationships

The dependency relationships that may exist between tasks. Finish to start is the most common logical relationship

Schedule baseline

The final, approved project schedule that is used during project execution to monitor project progress.

Critical Path "CP"

The longest path through the project. Activities with zero float are considered critical path tasks

Dependencies

The relationship between project activities

Dependency relationships

The type of dependency between two activities and the specific relationship between the activities.

Duration Compression

The use of techniques such as fast tracking or crashing to shorten the planned duration of a project or to resolve schedule slippage.

Crashing

This is a schedule compression technique that adds resources to the project to reduce the time it takes to complete the project.
