Direct Changeover
Big bang adoption or direct changeover is when a new system is adopted instantly, with no transition period between the old and new systems.Eason, 1988 When a new system needs to be implemented in an organization, there are three different ways to adopt this new system: the big bang adoption, phased adoption and parallel adoption. In case of parallel adoption the old and the new system are running parallel, so all the users can get used to the new system, and meanwhile do their work using the old system. Phased adoption means that the adoption will happen in several phases, so after each phase the system is a little nearer to be fully adopted. With the big bang adoption, the switch between using the old system and using the new system happens at one single date, the so-called instant changeover of the system. Everybody starts to use the new system at the same date and the old system will not be used anymore from that moment on. The advantage of a big bang adoption is that t ...

Adoption (software Implementation)
In computing, adoption means the transfer (conversion) between an old system and a target system in an organization (or more broadly, by anyone). If a company works with an old software system, it may want to use a new system which is more efficient, has more work capacity, etc. So then a new system needs to be adopted, after which it can be used by users. There are several adoption strategies that can be used to implement a system in an organization. The main strategies are big bang adoption, parallel adoption and phased adoption. "Big bang" is a metaphor for Big Bang, the cosmological theory of the same name, in which the start of the cosmos happened at one moment in time. This is also the case with the big bang adoption approach, in which the new system is supposed to be adopted wholesale on one date. In the case of parallel adoption, the old and the new system are run in parallel initially, so that all the users can get used to the new system, but still can do their work using ...

Adoption
Adoption is a process whereby a person assumes the parenting of another, usually a child, from that person's biological or legal parent or parents. Legal adoptions permanently transfer all rights and responsibilities, along with filiation, from the biological parents to the adoptive parents. Unlike guardianship or other systems designed for the care of the young, adoption is intended to effect a permanent change in status and as such requires societal recognition, either through legal or religious sanction. Historically, some societies have enacted specific laws governing adoption, while others used less formal means (notably contracts that specified inheritance rights and parental responsibilities without an accompanying transfer of filiation). Modern systems of adoption, arising in the 20th century, tend to be governed by comprehensive statutes and regulations. History Antiquity ;Adoption for the well-born While the modern form of adoption emerged in the United States, ...

Planning
Planning is the process of thinking regarding the activities required to achieve a desired goal. Planning is based on foresight, the fundamental capacity for mental time travel. The evolution of forethought, the capacity to think ahead, is considered to have been a prime mover in human evolution. Planning is a fundamental property of intelligent behavior. It involves the use of logic and imagination to visualise not only a desired end result, but the steps necessary to achieve that result. An important aspect of planning is its relationship to forecasting. Forecasting aims to predict what the future will look like, while planning imagines what the future could look like. Planning according to established principles is a core part of many professional occupations, particularly in fields such as management and business. Once a plan has been developed it is possible to measure and assess progress, efficiency and effectiveness. As circumstances change, plans may need to be modi ...

Implementation
Implementation is the realization of an application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy. Industry-specific definitions Computer science In computer science, an implementation is a realization of a technical specification or algorithm as a program, software component, or other computer system through computer programming and deployment. Many implementations may exist for a given specification or standard. For example, web browsers contain implementations of World Wide Web Consortium-recommended specifications, and software development tools contain implementations of programming languages. A special case occurs in object-oriented programming, when a concrete class implements an interface; in this case the concrete class is an ''implementation'' of the interface and it includes methods which are ''implementations'' of those methods specified by the interface. Information technology In the information technology during ...

Consensus Decision-making
Consensus decision-making or consensus process (often abbreviated to ''consensus'') are group decision-making processes in which participants develop and decide on proposals with the aim, or requirement, of acceptance by all. The focus on establishing agreement of at least the majority or the supermajority and avoiding unproductive opinion differentiates consensus from unanimity, which requires all participants to support a decision. Origin and meaning of terms The word ''consensus'' is Latin meaning "agreement, accord", derived from ''consentire'' meaning "feel together". Broadly, ''consensus'' relates to a generally accepted opinion, but in the context of this article refers to the process ''and'' the outcome of consensus decision-making (e.g. "to decide ''by'' consensus" and "''a'' consensus was reached"). History Consensus decision-making, as a self-described practice, originates from several nonviolent, direct action groups that were active in the Civil rights, Pe ...

PRINCE2
PRINCE2 (PRojects IN Controlled Environments) is a structured project management method and practitioner certification programme. PRINCE2 emphasises dividing projects into manageable and controllable stages. It is adopted in many countries worldwide, including the UK, Western European countries, and Australia. PRINCE2 training is available in many languages. PRINCE2 was developed as a UK government standard for information systems projects. In July 2013, ownership of the rights to PRINCE2 were transferred from HM Cabinet Office to AXELOS Ltd, a joint venture by the Cabinet Office and Capita, with 49% and 51% stakes respectively. History PRINCE was derived from an earlier method called PROMPT II (Project Resource Organisation Management Planning Techniques). In 1989 the Central Computer and Telecommunications Agency (CCTA) adopted a version of PROMPT II as a UK Government standard for information systems (IT) project management. They gave it the name 'PRINCE', which originally ...

Flash-cut
A flash cut, also called a flash cutover, is an immediate change in a complex system, with no phase-in period. In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs, split in January 1951 into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel on the same frequency, where the two cannot operate in parallel without interference. A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period. In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect. Also a series of short staccato shots that create a rhythmic effect.

Parallel Adoption
Parallel adoption is a method for transferring between a previous (Information technology, IT) system to a target (IT) system in an organization. In order to reduce risk, the old and new system run simultaneously for some period of time after which, if the criteria for the new system are met, the old system is disabled. The process requires careful planning and control and a significant investment in labor hours. Overview This entry focuses on the generic process of parallel adoption; (real-world) examples are used for a more meaningful interpretation of the process if necessary. Moreover a process-data model is used for visualizing the process which is intended to provide a complete overview of all the steps involved in the parallel adoption, but emphasis will be laid on the unique characteristics of parallel adoption. Some common characteristics, especially defining an implementation strategy, that go for all four generic kinds of adoption are described in Adoption (software imp ...

Phased Adoption
Phased adoption is a strategy of implementing an innovation (i.e., information systems, new technologies, processes, etc.) in an organization in a phased way, so that different parts of the organization are implemented in different subsequent time slots. Other concepts that are used are: phased implementation, phased conversion, phased approach, phased strategy, phased introduction and staged conversion. Overview Information Technology has revolutionized the way of working in organizations.Eason, K. (1988) Information Technology and Organisational Change. New York: Taylor and Francis With the introduction of high-tech Enterprise Resource Planning Systems (ERP), Content Management Systems (CMS), Customer Relationship Management, Customer and Supplier Relationship Management Systems (CRM and SRM), came the task to implement these systems in the organizations that are about to use it. The following entry will discuss just a small fraction of what has to be done or can be done when i ...

Organizational Learning
Organizational learning is the process of creating, retaining, and transferring knowledge within an organization. An organization improves over time as it gains experience. From this experience, it is able to create knowledge. This knowledge is broad, covering any topic that could better an organization. Examples may include ways to increase production efficiency or to develop beneficial investor relations. Knowledge is created at four different units: individual, group, organizational, and inter organizational. The most common way to measure organizational learning is a learning curve. Learning curves are a relationship showing how as an organization produces more of a product or service, it increases its productivity, efficiency, reliability and/or quality of production with diminishing returns. Learning curves vary due to organizational learning rates. Organizational learning rates are affected by individual proficiency, improvements in an organization's technology, and improve ...

SAP AG
Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Sap is distinct from latex, resin, or cell sap; it is a separate substance, separately produced, and with different components and functions. Insect honeydew is called sap, particularly when it falls from trees, but is only the remains of eaten sap and other plant parts. Types of sap Saps may be broadly divided into two types: xylem sap and phloem sap. Xylem sap Xylem sap (pronounced ) consists primarily of a watery solution of hormones, mineral elements and other nutrients. Transport of sap in xylem is characterized by movement from the roots toward the leaves. Over the past century, there has been some controversy regarding the mechanism of xylem sap transport; today, most plant scientists agree that the cohesion-tension theory best explains this process, but multiforce theorie ...
