Technology Acceptance Model
The technology acceptance model (TAM) is an information systems theory that models how users come to accept and use a technology. The ''actual system use'' is the end-point where people use the technology. ''Behavioral intention'' is a factor that leads people to use the technology. The behavioral intention (BI) is influenced by the ''attitude'' (A) which is the general impression of the technology. The model suggests that when users are presented with a new technology, a number of factors influence their decision about how and when they will use it, notably: *''Perceived usefulness'' (PU) – This was defined by Fred Davis as "the degree to which a person believes that using a particular system would enhance their job performance". It means whether or not someone perceives that technology to be useful for what they want to do. *''Perceived ease-of-use'' (PEOU) – Davis defined this as "the degree to which a person believes that using a particular system would be free from effor ...

Diffusion
Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in Gibbs free energy or chemical potential. It is possible to diffuse "uphill" from a region of lower concentration to a region of higher concentration, like in spinodal decomposition. The concept of diffusion is widely used in many fields, including physics ( particle diffusion), chemistry, biology, sociology, economics, and finance (diffusion of people, ideas, and price values). The central idea of diffusion, however, is common to all of these: a substance or collection undergoing diffusion spreads out from a point or location at which there is a higher concentration of that substance or collection. A gradient is the change in the value of a quantity, for example, concentration, pressure, or temperature with the change in another variable, usually distance. ...

Technology–organization–environment Framework
The technology-organization-environment framework, also known as the TOE framework, is a theoretical framework that explains technology adoption in organizations and describes how the process of adopting and implementing technological innovations are influenced by the technological context, organizational context, and environmental context. Louis G. Tornatzky and Mitchell Fleischer published the model in 1990. Numerous application examples of the TOE framework have been summarized by Olivera and Martins (2011). As Awa, Ojiabo & Orokor (2017) reiterated, the TOE framework is for organizational level analysis. The framework focuses on higher level attributes (i.e. the technological, organizational, and environmental contexts) instead of detailed behaviors of individuals in the organization. To understand technology adoption at individual level, behavioral models such as the theory of reasoned action, the theory of planned behavior, and the technology acceptance model The technolog ...

Theory Of Planned Behavior
The theory of planned behavior (TPB) is a psychological theory that links beliefs to behavior. The theory maintains that three core components, namely, attitude, subjective norms, and perceived behavioral control, together shape an individual's behavioral intentions. In turn, a tenet of TPB is that behavioral intention is the most proximal determinant of human social behavior. The theory was elaborated by Icek Ajzen for the purpose of improving the predictive power of the theory of reasoned action (TRA). Ajzen's idea was to include perceived behavioral control in TPB. Perceived behavior control was not a component of TRA. TPB has been applied to studies of the relations among beliefs, attitudes, behavioral intentions, and behaviors in various human domains. These domains include, but are not limited to, advertising, public relations, advertising campaigns, healthcare, sport management, and sustainability.

Technology Lifecycle
The technology life-cycle (TLC) describes the commercial gain of a product through the expense of research and development phase, and the financial return during its "vital life". Some technologies, such as steel, paper or cement manufacturing, have a long lifespan (with minor variations in technology incorporated with time) while in other cases, such as electronic or pharmaceutical products, the lifespan may be quite short. The TLC associated with a product or technological service is different from product life-cycle (PLC) dealt with in product life-cycle management. The latter is concerned with the life of a product in the marketplace with respect to timing of introduction, marketing measures, and business costs. The ''technology'' underlying the product (for example, that of a uniquely flavoured tea) may be quite marginal but the process of creating and managing its life as a branded product will be very different. The technology life cycle is concerned with the time and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology Adoption Lifecycle
The technology adoption lifecycle is a sociological model that describes the adoption or acceptance of a new product or innovation, according to the demographic and psychological characteristics of defined adopter groups. The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve". The model indicates that the first group of people to use a new product is called "innovators", followed by "early adopters". Next come the early majority and late majority, and the last group to eventually adopt a product are called "Laggards" or "phobics." For example, a phobic may only use a cloud service when it is the only remaining method of performing a required task, but the phobic may not have an in-depth technical knowledge of how to use the service. The demographic and psychological (or "psychographic") profiles of each adoption group were originally specified by the North Central Rural Sociology Committee (Subcommittee for the Study of the Dif ...

Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Product Life Cycle Management
Product life-cycle management (PLM) is the succession of strategies by business management as a product goes through its life-cycle. The conditions in which a product is sold (advertising, saturation) changes over time and must be managed as it moves through its succession of stages. Goals The goals of product life cycle management (PLM) are to reduce time to market, improve product quality, reduce prototyping costs, identify potential sales opportunities and revenue contributions, maintain and sustain operational serviceability, and reduce environmental impacts at end-of-life. To create successful new products the company must understand its customers, markets and competitors. Product Lifecycle Management (PLM) integrates people, data, processes and business systems. It provides product information for companies and their extended supply chain enterprise. PLM solutions help organizations overcome the increased complexity and engineering challenges of developing new products for ...

New Product Development
In business and engineering, new product development (NPD) covers the complete process of bringing a new product to market, renewing an existing product or introducing a product in a new market. A central aspect of NPD is product design, along with various business considerations. New product development is described broadly as the transformation of a market opportunity into a product available for sale. The products developed by an organisation provide the means for it to generate income. For many technology-intensive firms their approach is based on exploiting technological innovation in a rapidly changing market. The product can be tangible (something physical which one can touch) or intangible (like a service or experience), though sometimes services and other processes are distinguished from "products". NPD requires an understanding of customer needs and wants, the competitive environment, and the nature of the market. Cost, time, and quality are the main variables that d ...

List Of Marketing Topics
The following outline is provided as an overview of and topical guide to marketing: Marketing – social and managerial processes by which products, services, and value are exchanged in order to fulfill individuals' or groups' needs and wants. These processes include, but are not limited to, advertising, promotion, distribution, and product management. Core concepts in marketing Marketers may sell goods or services directly to consumers, known as business to customer (B2C marketing); commercial organizations (known as business to business marketing or B2B), to government; to not-for-profit organizations ( Not-for-profit organization (NFP)) or some combination of any of these. Actors and relationships : At the center of the marketing framework is the consumer lies the relationship between the consumer and the organization with the implication that marketers must manage the way the organization presents its public face. :: The consumer: Typically, the consumer refers to ...

Lazy User Model
The lazy user model of solution selection (LUM) is a model in information systems proposed by Tétard and Collan that tries to explain how an individual selects a solution to fulfill a need from a set of possible solution alternatives. LUM expects that a solution is selected from a set of available solutions based on the amount of effort the solutions require from the user – the user is supposed to select the solution that carries the least effort. The model is applicable to a number of different types of situations, but it can be said to be closely related to technology acceptance models. The model draws from earlier works on how least effort affects human behaviour in information seeking and in scaling of language. Earlier research within the discipline of information systems especially within the topic of technology acceptance and technology adoption is closely related to the lazy user model. The model structure The model starts from the observation that there is a " use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
