Stovepipe (organisation)
A stovepipe organization (alt organisations) has a structure which largely or entirely restricts the flow of information within the organization to up-down through lines of control, inhibiting or preventing cross-organisational communication. Many traditional, large (especially governmental or transnational) organizations have (or risk having) a stovepipe pattern. Intelligence organizations may deliberately adopt a stovepipe pattern so that a breach or compromise in one area cannot easily spread to others. A famous example of this is Bletchley Park (an allied forces Second World War codebreaking centre where messages encrypted by the Enigma machine were decrypted) where people working in one hut would not know what the people in any other hut did. A stovepipe pattern is most likely to develop in organisations that have some or all of the following characteristics: * Very hierarchical with sharply defined roles or areas of influence (e.g. regional sales teams) * Long reporting lines ...

Bletchley Park
Bletchley Park is an English country house and estate in Bletchley, Milton Keynes ( Buckinghamshire) that became the principal centre of Allied code-breaking during the Second World War. The mansion was constructed during the years following 1883 for the financier and politician Sir Herbert Leon in the Victorian Gothic, Tudor, and Dutch Baroque styles, on the site of older buildings of the same name. During World War II, the estate housed the Government Code and Cypher School (GC&CS), which regularly penetrated the secret communications of the Axis Powersmost importantly the German Enigma and Lorenz ciphers. The GC&CS team of codebreakers included Alan Turing, Gordon Welchman, Hugh Alexander, Bill Tutte, and Stuart Milner-Barry. The nature of the work at Bletchley remained secret until many years after the war. According to the official historian of British Intelligence, the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and without it th ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codebreaking
Cryptanalysis (from the Greek ''kryptós'', "hidden", and ''analýein'', "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. In addition to mathematical analysis of cryptographic algorithms, cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation. Even though the goal has been the same, the methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity, ranging from the pen-and-paper methods of the past, through machines like the British Bombes and Colossus computers at Bletchley Park in World War II, to the mathematically advanced comput ...

Information Technology
Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data . and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term ''information technology'' in its modern sense first appeared in a 1958 article published in the ''Harvard Business Review''; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Resources
Human resources (HR) is the set of people who make up the workforce of an organization, business sector, industry, or economy. A narrower concept is human capital, the knowledge and skills which the individuals command. Similar terms include manpower, Labour (human activity), labor, personnel, associates or simply: people. The Human Resources department (HR department) of an organization performs human resource management, overseeing various aspects of employment, such as compliance with labor law and employment standards, job interview, interviewing and selection, performance management, administration of Employee benefits, organizing of employee files with the required documents for future reference, and some aspects of recruitment (also known as talent acquisition) and employee offboarding. They serve as the link between an organization's management and its employees. The duties include planning, recruitment and selection process, posting job ads, evaluating the performance ...

Information Silo
An information silo, or a group of such silos, is an insular management system in which one information system or subsystem is incapable of reciprocal operation with others that are, or should be, related. Thus information is not adequately shared but rather remains sequestered within each system or subsystem, figuratively trapped within a container like grain is trapped within a silo: there may be much of it, and it may be stacked quite high and freely available within those limits, but it has no effect outside those limits. Such data silos are proving to be an obstacle for businesses wishing to use data mining to make productive use of their data. Information silos occur whenever a data system is incompatible or not integrated with other data systems. This incompatibility may occur in the technical architecture, in the application architecture, or in the data architecture of any data system. However, since it has been shown that established data modeling methods are the root cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mushroom Management
Mushroom management is the management of a company where the communication channels between the employers and the employees do not work effectively, and where employees are 'kept in the dark' by management in regards to business decisions that affect their work and employment. The term 'mushroom management' alludes to the stereotypical (and somewhat inaccurate) view of mushroom cultivation: kept in the dark and fed bullshit. Description Mushroom management is a style of management in which the personnel are not familiar with the ideas or the general state of the company, and are given work without knowing the purpose of this work, in contrast with open-book management. Mushroom management means that workers' curiosity and self-expression are not supported. The employees often have no idea what the company's overall situation is, because the leaders tend to make all the decisions on their own, without asking anyone else to give their opinion. This problem can occur when the manag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stovepipe System
In engineering and computing, "stovepipe system" is a pejorative term for a system that has the potential to share data or functionality with other systems but which does not do so. The term evokes the image of stovepipes rising above buildings, each functioning individually. A simple example of a stovepipe system is one that implements its own user IDs and passwords, instead of relying on a common user ID and password shared with other systems. Stovepipes are A stovepipe system is generally considered an example of an anti-pattern, particularly found in legacy systems. This is due to the lack of code reuse, and resulting software brittleness due to potentially general functions only being used on limited input. However, in certain cases stovepipe systems are considered appropriate, due to benefits from vertical integration and avoiding dependency hell.''Joel on Software,''In Defense of Not-Invented-Here Syndrome, by Joel Spolsky, October 14, 2001 For example, the Microsoft Excel ...

Anti-patterns
An anti-pattern in software engineering, project management, and business processes is a common response to a recurring problem that is usually ineffective and risks being highly counterproductive. The term, coined in 1995 by computer programmer Andrew Koenig, was inspired by the book ''Design Patterns'' (which highlights a number of design patterns in software development that its authors considered to be highly reliable and effective) and first published in his article in the ''Journal of Object-Oriented Programming''. A further paper in 1996 presented by Michael Ackroyd at the Object World West Conference also documented anti-patterns. It was, however, the 1998 book ''AntiPatterns'' that both popularized the idea and extended its scope beyond the field of software design to include software architecture and project management. Other authors have extended it further since to encompass environmental/organizational/cultural anti-patterns. Definition According to the authors of '' ...
