Gartner hype cycle

The hype cycle framework was introduced in 1995 by Gartner analyst Jackie Fenn, who had joined the firm the year before. In her research reports, Fenn identified common patterns related to the maturity of emerging technologies. Fenn referred to this familiar progression as a "hype cycle" and created a graph depicting its ups and downs with each distinct stage given a title, starting with Technology trigger and ending with Plateau of productivity. The chart was included in a one-off research report, but it was popular with other Gartner analysts and clients and the "Hype Cycle of Emerging Technologies" was soon developed into an annual report. ==Five phases==

Each hype cycle consists of five key phases of a technology's life cycle. ;1. Technology trigger :A potential technology breakthrough kicks things off. Early proof-of-concept stories and media interest trigger significant publicity. Often no usable products exist and commercial viability is unproven. ;2. Peak of inflated expectations :Early publicity produces a number of success stories—often accompanied by scores of failures. Some companies take action; most do not. ;3. Trough of disillusionment :Interest wanes as experiments and implementations fail to deliver. Producers of the technology shake out or fail. Investment continues only if the surviving providers improve their products to the satisfaction of early adopters. ;4. Slope of enlightenment :More instances of the technology's benefits start to crystallize and become more widely understood. Second- and third-generation products appear from technology providers. More enterprises fund pilots; conservative companies remain cautious. ;5. Plateau of productivity :Mainstream adoption starts to take off. Criteria for assessing provider viability are more clearly defined. The technology's broad market applicability and relevance are clearly paying off. If the technology has more than a niche market, then it will continue to grow. The term "hype cycle" and each of the associated phases are now used more broadly in the marketing of new technologies. ==Hype in new media==

Hype (in the more general media sense of the term "hype" and that created "debunking" responses. A longer-term historical perspective on such cycles can be found in the research of the economist Carlota Perez. Desmond Roger Laurence, in the field of clinical pharmacology, described a similar process in drug development in the seventies. ==Criticisms of the model==

There have been numerous criticisms of the hype cycle model. Prominent among them are that it is not a cycle, that the outcome does not depend on the nature of the technology itself, that it is not scientific in nature, and that it does not reflect changes over time in the speed at which technology develops. Another is that it is limited in its application, as it prioritizes economic considerations in decision-making processes. It seems to assume that a business' performance is tied to the hype cycle, whereas this may actually have more to do with the way a company devises its branding strategy. A related criticism is that the "cycle" has no real benefits to the development or marketing of new technologies and merely comments on pre-existing trends. Specific disadvantages when compared to, for example, technology readiness level are: • The cycle is not scientific in nature, and there is no data or analysis that would justify the cycle. • With the (subjective) terms disillusionment, enlightenment and expectations it cannot be described objectively or clearly where technology now really is. • The terms are misleading in the sense that one gets the wrong idea what they can use a technology for. The user does not want to be disappointed, so should they stay away from technology in the Trough of Disillusionment? • No action perspective is offered to move technology to a next phase. • This appears to be a very simplified impulse response of an elastic system representable by a differential equation. Perhaps more telling would be to formulate a system model with solutions conforming to observable behavior. An analysis of Gartner Hype Cycles since 2000 == See also ==
