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 ...

Project Network
A project network diagram, also known an activity network diagram (AND) is a information graphics, graph that displays the order in which a project’s activities are to be completed. Derived from the work breakdown structure, the Work breakdown structure#Terminal element, terminal elements of a project are organized sequentially based on the relationship among them. It is typically drawn from left to right to reflect project chronology. Techniques Activity-on-Node The Activity-on-Node (AON) technique uses nodes to represent individual project activities and path arrows to designate the sequence of activity completion. Nodes are labelled using information pertaining to the activity. According to Project Management, nodes should at least display the following information: * Identifier * Descriptive label * Activity duration * Early start time * Early finish time * Late start time * Late finish time * Activity float (slack) Start and finish times are used to determine th ...

Resource Leveling
In project management, resource leveling is defined by '' A Guide to the Project Management Body of Knowledge'' (''PMBOK Guide'') as "A technique in which start and finish dates are adjusted based on resource limitation with the goal of balancing demand for resources with the available supply." Resource leveling problem could be formulated as an optimization problem. The problem could be solved by different optimization algorithms such as exact algorithms or meta-heuristic methods. When performing project planning activities, the manager will attempt to schedule certain tasks simultaneously. When more resources such as machine A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromol ...s or people are needed than are available, or perhaps a specific person is needed in both tasks, the tasks ...

Outline Of Project Management
The following outline is provided as an overview of and topical guide to project management: Project management – discipline of planning, organizing, securing, managing, leading, and controlling resources to achieve specific goals. A project is a temporary endeavor with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables), undertaken to meet unique goals and objectives, typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with ongoing business operations. What type of thing is project management? Project management can be described as all of the following: * Management – in business and human organization activity is simply the act of getting people together to accomplish desired goals. Management comprises planning, organizing, staffing, leading or directing, and controlling an organization (a group of one or more people or entities) or effort for the pu ...

Dependency Structure Matrix
The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix, incidence matrix, ''N2'' matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the form of a square matrix.S.D. Eppinger and T.R. BrowningDesign Structure Matrix Methods and Applications MIT Press, Cambridge, 2012. It is the equivalent of an adjacency matrix in graph theory, and is used in systems engineering and project management to model the structure of complex systems or processes, in order to perform system analysis, project planning and organization design. Don Steward coined the term "design structure matrix" in the 1960s, using the matrices to solve mathematical systems of equations. Overview A design structure matrix lists all constituent subsystems/ activities and the corresponding information exchange, interactio ...

Critical Chain
Critical chain project management (CCPM) is a method of planning and managing projects that emphasizes the resources (people, equipment, physical space) required to execute project tasks. It was developed by Eliyahu M. Goldratt. It differs from more traditional methods that derive from critical path and PERT algorithms, which emphasize task order and rigid scheduling. A critical chain project network strives to keep resources levelled, and requires that they be flexible in start times. Origins Critical chain project management is based on methods and algorithms derived from Theory of Constraints. The idea of CCPM was introduced in 1997 in Eliyahu M. Goldratt's book, ''Critical Chain''. The application of CCPM has been credited with achieving projects 10% to 50% faster and/or cheaper than the traditional methods (i.e., CPM, PERT, Gantt, etc.) developed from 1910 to 1950s. According to studies of traditional project management methods by Standish Group and others as of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Path Method
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for schedule (project management), scheduling a set of project activities. A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish. It is commonly used in conjunction with the program evaluation and review technique (PERT). History The CPM is a project-modeling technique developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley Jr. of Remington Rand. Kelley and Walker related their memories of the development of CPM in 1989. Kelley attributed the term "critical path" to the developers of the PERT, which was developed at about the same time by Booz Allen Hamilton and the U.S. Navy. The precursors of what came to be known as critical path were developed and put into practice by DuPont between 1940 and 1943 and contributed to the success of the Manhattan Project.

Resource (project Management)
In project management, resources are required to carry out the project tasks. These can be people, equipment, facilities, funding, or anything else capable of definition (usually other than labour) required for the completion of a project activity. The lack of a resource can therefore be a constraint on the completion of the project activity. Resources may be storable or not storable. Storable resources remain available unless depleted by usage, and may be replenished by project tasks that produce them. Nonstorable resources must be renewed for each time period, even if not used in previous periods. Resource scheduling, availability, and optimisation are considered key to successful project management. Allocation of limited resources is based on the priority given to each of the project activities. Their priorities are calculated using the critical path method and heuristic analysis. For a case with a constraint on the available resources, the objective is to create the most e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Project
A project is a type of assignment, typically involving research or design, that is carefully planned to achieve a specific objective. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system (work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints. A project may form a part of wider programme management or function as an ''ad hoc'' system. Open-source software "projects" or artists' musical "projects" (for example) may lack defined team-membership, precise planning and/or time-limited durations. Overview The word ''project'' comes from the Latin word ''projectum'' from the Latin verb ''proicere'', "before an action", which in turn comes from ''pro-'', which denotes precedence, something that comes before ...
