Arrow Diagramming Method (ADM):

A

Arrow diagramming method is a network diagramming technique used in Project Management in which activities are represented by arrows. ADM is also known as the activity-on-arrow (AOA) method.

Q

What is ADM used for?

A

ADM is used for scheduling activities in a project plan. Precedence relationships between activities are represented by circles connected by one or more arrows. The length of the arrow represents the duration of the relevant activity. ADM only shows finish-to-start (FS) relationships, where each activity is completed before the successor activity starts.

Q

Critical Path Analysis

A

The analysis of a project schedule by its critical path or longest path. The analysis aims to understand whether the project can be completed on time and what key activities or milestones are a risk to the project’s timely completion. An advanced analysis may consider near-critical paths or other risk paths of the project.

Indirect costs are costs that are not directly accountable to an activity or work package. Indirect costs may be either fixed or variable. Indirect costs include administration and personnel. These are those costs which are not directly related to production. Some indirect costs may be overhead. But some overhead costs can be directly attributed to a project and are direct costs.

A

The latest possible start date for an activity to start without affecting the target finish date for the project.

Q

Master Schedule

A

A high-level summary schedule or a schedule that is a combination of other independent sub-schedules.

49
Q

Milestone

A

An event to mark specific points in time along a project timeline. These points may signal anchors such as a project start and end date, a need for external review or input and budget checks, among others. In many instances, milestones do not impact project duration. Instead, they focus on major progress points that must be reached to achieve success.

A

A percentage value between 0 and 100 that indicates the partial completeness of an activity, project or work package.

54
Q

PERT

A

Program Evaluation and Review Technique is a statistical tool, used in project management, which was designed to analyze and represent the tasks involved in completing a given project. First developed by the United States Navy in the 1950s, it is commonly used in conjunction with the critical path method (CPM).

55
Q

Physical Completion

A

Progress assessed by a physical measurement

56
Q

A

Project planning is part of project management, which relates to the use of schedules such as Gantt charts to plan and subsequently report progress within the project environment. Initially, the project scope is defined and the appropriate methods for completing the project are determined.

57
Q

Planned Cost

A

An approved estimated cost for the project or items that will be used.

58
Q

Planning Engineer

A

A specialist engineer who develops the project timescale schedules, and manages them using a software package.

A

A predecessor activity is an activity that determines the start date or finish date of a following activity based on a logical relationship.

60
Q

Potential Change Requests

A

Documentation that tracks potential changes to your project’s estimated costs, resources or supplies. Allows you to identify any anticipated impacts to the project scope. Once reviewed by stakeholders, a change order can be requested to have these changes implemented

61
Q

Precedence Diagramming Method (PDM)

A

Precedence Diagramming Method is a network diagramming technique used to establish order or execution in project schedules. PDM network diagrams use boxes, referred to as nodes, to represent activities and connects them with arrows that represent the dependencies between activities.

62
Q

Procurement

A

Procurement is the acquisition of goods, services or works from an outside external source. It is favorable that the goods, services or works are appropriate and that they are procured at the best possible cost to meet the needs of the acquirer in terms of quality and quantity, time, and location.

63
Q

Project Control

A

The setting and monitoring of cost/schedule deliverables, identification and anticipation of variances and implementation of preventive and recovery actions of approved changes

64
Q

A

A fixed activity due date or deadline.

70
Q

Overall progress completion measurement, using activity weightings to normalize disparate activities.

73
Q

Work Breakdown Structure

A

A work-breakdown structure (WBS) in project management and project controls, is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project deliverable that organizes the project’s work into manageable sections. See construction WBS examples here.

74
Q

Work Package

A

A work package (WP) is a subset of a project that can be assigned to a specific part for execution. Because of the similarity, work packages are often misidentified as projects.
