Timeline Of Project Management
Timeline of project management - there is a general understanding that the history of modern project management started around 1950. Until 1900, projects were generally managed by creative architects and engineers themselves, among those, for example, Christopher Wren, Thomas Telford and Isambard Kingdom Brunel. Early civilizations * 2570 BC Great pyramid of Giza completed. Some records remain of how the work was managed: e.g. there were managers of each of the four faces of the pyramid, responsible for their completion ( subproject managers). * 208 BC The first major construction of the Great Wall of China. 17th - 19th century * Christopher Wren (1632–1723) was a 17th-century English designer, astronomer, geometer, mathematician-physicist and architect. Wren designed 55 of 87 London churches after the Great fire of London in 1666, such as St Paul's Cathedral in 1710, as well as many secular buildings. * Thomas Telford (1757-1834) was a Scottish stonemason, architect and ...

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined 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 clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Goal
''The Goal'' is a management-oriented novel by Eliyahu M. Goldratt, a business consultant known for his theory of constraints, and Jeff Cox, the author of many management-oriented novels. ''The Goal'' was originally published in 1984 and has since been revised and republished. This book can be used for case studies in operations management, with a focus geared towards the theory of constraints, bottlenecks and how to alleviate them, and applications of these concepts in real life.

Essays On Software Engineering
An essay is, generally, a piece of writing that gives the author's own argument, but the definition is vague, overlapping with those of a letter, a paper, an article, a pamphlet, and a short story. Essays have been sub-classified as formal and informal: formal essays are characterized by "serious purpose, dignity, logical organization, length," whereas the informal essay is characterized by "the personal element (self-revelation, individual tastes and experiences, confidential manner), humor, graceful style, rambling structure, unconventionality or novelty of theme," etc. Essays are commonly used as literary criticism, political manifestos, learned arguments, observations of daily life, recollections, and reflections of the author. Almost all modern essays are written in prose, but works in verse have been dubbed essays (e.g., Alexander Pope's ''An Essay on Criticism'' and ''An Essay on Man''). While brevity usually defines an essay, voluminous works like John Locke's ''An E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 tasks involved in completing a given project. First developed by the United States Navy in 1958, it is commonly used in conjunction with the critical path method (CPM) that was introduced in 1957. Overview PERT is a method of analyzing the tasks involved in completing a given 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 of an event-oriented technique rather than start- and completion-oriented, and is used more in those projects where time is the major factor rather than cost. It is applied on very large-scale, one-time, complex, non-routine infrastructure and on Research and Developmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cost Engineer
Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis". "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements." Skills and knowledge of cost engineers are similar to those of quantity surveyors. In many industries, cost engineering is synonymous with project controls. As the title "engineer" has legal requirements in many jurisdictions (i.e. Texas, Canada), the cost engineering discipline is often renamed to project controls. A cost engineer is "an engineer whose judgment and experience are utilized in the application of scientific principles and techniques to problems of estimation; cost control; business planning and management science; profitability analysis; project management; and planning and scheduling". Overview One key objective of cost eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UGM-27 Polaris
The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army, and had influenced the design by making it squat so it would fit in submarines. However, they had concerns about the use of liquid fuel rockets on board ships, and some consideration was given to a solid fuel version, Jupiter S. In 1956, during an anti-submarine study known as Project Nobska, Edward Teller suggested that very small hydrogen bomb warheads were possible. A crash program to develop a missile suitable for carrying such warheads began as Polaris, launching its first shot less than four years later, in February 1960. As the Polaris missile was fired underwater from a moving platform, it was essentially invulnerable to counterattack. This led the Navy to suggest, starting around 1959, that the ...
