Arrow Diagramming Method

	Arrow Diagramming Method Arrow diagramming method (ADM) is a network diagramming technique in which activities are represented by arrows. ADM is also known as the activity-on-arrow (AOA) method. Usage 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 relationships, meaning that each activity is completed before the successor activity starts. Sometimes a "dummy task" is added, to represent a dependency between tasks, which does not represent any actual activity. The dummy task is added to indicate precedence that can't be expressed using only the actual activities. Such a dummy task often has a completion time of 0. Use of ADM as a common project management practice has declined with the adoption of computer-based scheduling tools. In addition, the precedence diagram method (PDM), or a ...

	Project Plan A project plan, is a series of structured tasks, objectives, and schedule to a complete a desired outcome, according to a project managers designs and purpose. According to the Project Management Body of Knowledge (PMBOK), is: "...a formal, approved document used to guide both ''project execution'' and ''project control''. The primary uses of the project plan are to document planning assumptions and decisions, facilitate communication among ''project stakeholders'', and document approved scope, cost, and schedule ''baselines''. A project plan may be sumarized or detailed." The latest edition of the PMBOK (v6) uses the term '' project charter'' to refer to the contract that the project sponsor and project manager use to agree on the initial vision of the project (scope, baseline, resources, objectives, etc.) at a high level. In the PMI methodology described in the PMBOK v5, the project charter and the project management plan are the two most important documents for describin ...

	Dependency (project Management) In a project network, a dependency is a link among a project's Work breakdown structure#Terminal element, terminal elements. The A Guide to the Project Management Body of Knowledge, A Guide to the Project Management Body of Knowledge (PMBOK Guide) does not define the term dependency, but refers for this term to a logical relationship, which in turn is defined as ''dependency between two activities, or between an activity and a milestone''. Standard types of dependencies There are four standard types of dependencies: # Finish to start (FS) #* ''A'' FS ''B'' means "activity A must finish before activity B can begin" (or "B can't start until A has finished").image:Dependency-FS.png #* ''(Foundations dug) FS (Concrete poured)'' # Finish to finish (FF) #* ''A'' FF ''B'' means "activity A must finish before activity B can finish" (or "B can't finish before A is finished") . image:Dependency-FF.png #* ''(Last chapter written) FF (Entire book written)'' # Start to start (SS). #* ''A'' S ...

picture info	Precedence Diagram Method The precedence diagram method (PDM) is a tool for Schedule (project management), scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the Dependency (project management), dependencies. It is also called the activity-on-node (AON) method. * Critical Task (project management), tasks, noncritical tasks, and slack time * Shows the relationship of the tasks to each other * Allows for what-if, worst-case, best-case and most likely scenario Key elements include determining predecessors and defining attributes such as * early start date * late start date * early finish date * late finish date * duration * activity name * Work breakdown structure, WBS reference Slack/Float (project management), Float: Determines the duration of activity delay that the project can tolerate before the project comes in late.

picture info	Program Evaluation And Review Technique The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the task (project management), tasks involved in completing a given project. PERT was originally developed by Charles E. Clark for the United States Navy in 1958; it is commonly used in conjunction with the Critical Path Method (CPM), which was also introduced in 1958. Overview PERT is a method of analyzing the tasks involved in completing a project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. It incorporates uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more event-oriented than start- and completion-oriented, and is used more for projects where time is the major constraint rather than cost. It is applied to very large-scale, one-time, complex, non-routine infrastru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
