Float (project Management)
In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: * subsequent tasks ("''free float''") * project completion date ("''total float''"). ''Total float'' is associated with the path. If a project network chart/diagram has 4 non-critical paths, then that project would have 4 ''total float'' values. The ''total float'' of a path is the combined ''free float'' values of all activities in a path. The ''total float'' represents the schedule flexibility and can also be measured by subtracting early start dates from late start dates of path completion. Float is core to critical path method, with the total floats of noncritical activities key to computing the critical path drag of an activity, i.e., the amount of time it is adding to the project's duration.* Example Consider the process of replacing a broken pane of glass in the window of your home. There are various component activities involved in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Management
Project management is the process of supervising the work of a Project team, team to achieve all project goals within the given constraints. This information is usually described in project initiation documentation, project documentation, created at the beginning of the development process. The primary constraints are Scope (project management), scope, time and budget. The secondary challenge is to operations research, optimize the Resource allocation, allocation of necessary inputs and apply them to meet predefined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are established, they should influence all decisions made by other people involved in the project– for example, project managers, designers, contractors and subcontractors ...

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 ...

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 ...

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.

Critical Path Drag
Critical path drag is a project management metric developed by Stephen Devaux as part of the Total Project Control (TPC) approach to schedule analysis and compression in the critical path method of scheduling. Critical path drag is the amount of time that an activity or constraint on the critical path is adding to the project duration. Alternatively, it is the maximum amount of time that one can shorten the activity before it is no longer on the critical path or before its duration becomes zero. In networks where all dependencies are finish-to-start (FS) relationships (i.e., where a predecessor must finish before a successor starts), the drag of a critical path activity is equal to whichever is less: its remaining duration or (if there is one or more parallel activity) the total float of the parallel activity that has the least total float. In this diagram, Activities A, B, C, D, and E comprise the critical path, while Activities F, G, and H are off the critical path with fl ...

Glossary Of Project Management
A glossary of terms relating to Project Management, project management and consulting. A * Agile software development is a set of fundamental principles about how software should be developed based on an agile way of working in contrast to previous heavy-handed software development methodologies. * Aggregate planning is an operational activity which does an aggregate plan for the production process, in advance of 2 to 18 months, to give an idea to management as to what quantity of materials and other resources are to be procured and when, so that the total cost of operations of the organization is kept to the minimum over that period. * Allocation of resources, Allocation is the assignment of available resources in an economic way. B * Benefits management plan a document that describes the activities necessary for achieving the benefits of a project and when these planned benefits will be delivered.

List Of Project Management Topics
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 ...
