Product Ecosystem Theory
Product ecosystem theory is an emerging theory that describes how the design of manufactured products evolves over time and draws parallels with how species evolve within a natural ecosystem. Fundamental to this theory is that manufactured product lines respond to external threats and opportunities in much the same way that species respond to threats and opportunities. Competition and other environmental pressures may cause a species to become extinct. An example of the parallel in consumer products is the way in which the typewriter became displaced (or extinct) due to pressures from the personal computer. Products lines can be seen to incrementally change and branch over time following the principle of phyletic gradualism. Or they can be seen to have periods of stasis followed by disruptive innovation. This follows the principle of punctuated equilibrium In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a Scientific theory, theory that p ...

Durable Goods
In economics, a durable good or a hard good or consumer durable is a Good (economics), good that does not quickly wear out or, more specifically, one that yields utility over time rather than being completely Consumption (economics), consumed in one use. Items like bricks could be considered perfectly durable goods because they should theoretically never wear out. Highly durable goods such as refrigerators or cars usually continue to be useful for several years of use, so durable goods are typically characterized by long periods between successive purchases. Nondurable goods or soft goods (consumables) are the opposite of durable goods. They may be defined either as goods that are immediately consumed in one use or ones that have a lifespan of less than three years. Examples of nondurable goods include fast-moving consumer goods such as food, cosmetics, cleaning products, medication, clothing, packaging and fuel. While durable goods can usually be rented as well as bought, nondurab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Manufactured Product
A final good or consumer good is a final product ready for sale that is used by the consumer to satisfy current wants or needs, unlike an intermediate good, which is used to produce other goods. A microwave oven or a bicycle is a final good. When used in measures of national income and output, the term "final goods" includes only new goods. For example, gross domestic product (GDP) excludes items counted in an earlier year to prevent double counting (accounting), double counting based on resale of items. In that context, the economic definition of goods also includes what are commonly known as ''service (economics), services''. Manufacturing, Manufactured goods refer to products that have undergone processing or assembly, distinguishing them from raw materials. Law Various legal definitions exist for consumer products, depending on jurisdiction. One such definition is found in the United States' Consumer Product Safety Act, which provides extensive explanation of consumer pr ...

Phyletic Gradualism
Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual.Eldredge, N. and S. J. Gould (1972)"Punctuated equilibria: an alternative to phyletic gradualism"In T.J.M. Schopf, ed., ''Models in Paleobiology''. San Francisco: Freeman Cooper. p. 84. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis). In this view no clear line of demarcation exists between an ancestral species and a descendant species, unless splitting occurs. The theory is contrasted with punctuated equilibrium. History The word ''phyletic'' derives from the Greek φυλετικός ''phūletikos'', which conveys the meaning of a line of descent. Phyletic gradualism contrasts with the theory of punctuated equilibrium, which proposes that most evolution occurs isolated in rare episodes of rapid evolution, when a single species splits into two distinct species, follow ...

Punctuated Equilibrium
In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a Scientific theory, theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolution, evolutionary change for most of its geological history. : ''Reprinted in'' * * This state of little or no morphological change is called ''stasis''. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologic time scale, geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another. Punctuated equilibrium is commonly contrasted with phyletic gradualism, the idea that evolution generally occurs uniformly by the steady and gradual transformation of whole lineages (anagenesis). In 1972, paleontologists Niles Eldredge and Stephen Jay Goul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CityCar
The A-segment is the first category in the passenger car classification system defined by the European Commission. It is used for city cars, the smallest category of passenger cars defined. A-segment sales represented approximately 4.2% of the European market in 2024. It is approximately equivalent to the kei car class in Japan. Definition As of 2021, the A-segment category size spans from approximately to . Characteristics Body styles for A-segment cars in Europe are always hatchbacks. But as crossovers gain popularity, new models may shift to resemble crossovers. Examples of crossover city cars include Suzuki Ignis and Toyota Aygo X. Other body styles such as sedans are not present in this segment because these shapes largely prove impractical at typical A-segment dimensions. Current models In 2020 the ten highest selling A-segment cars in Europe were Fiat Panda, Fiat 500, Toyota Aygo, Renault Twingo, Volkswagen Up!, Hyundai i10, Kia Picanto, Peugeot 108, Citroën ...

Manufactured Goods
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed i ...

Theories
A theory is a systematic and rational form of abstract thinking about a phenomenon, or the conclusions derived from such thinking. It involves contemplative and logical reasoning, often supported by processes such as observation, experimentation, and research. Theories can be scientific, falling within the realm of empirical and testable knowledge, or they may belong to non-scientific disciplines, such as philosophy, art, or sociology. In some cases, theories may exist independently of any formal discipline. In modern science, the term "theory" refers to scientific theories, a well-confirmed type of explanation of nature, made in a way consistent with the scientific method, and fulfilling the criteria required by modern science. Such theories are described in such a way that scientific tests should be able to provide empirical support for it, or empirical contradiction (" falsify") of it. Scientific theories are the most reliable, rigorous, and comprehensive form of scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Product Design
Product design is the process of creating new Product (business), products for businesses to sell to their customers. It involves the generation and development of ideas through a systematic process that leads to the creation of innovative products. Thus, it is a major aspect of new product development. ''Product design process:'' The product design process is a set of strategic and tactical activities, from idea generation to commercialization, used to create a product design. In a systematic approach, product designers conceptualize and evaluate ideas, turning them into tangible inventions and products. The product designer's role is to combine art, science, and technology to create new products that people can use. Their evolving role has been facilitated by Digital data, digital tools that now allow designers to do things that include communicate, visualize, analyze, 3D modeling and actually produce tangible ideas in a way that would have taken greater human resources in the p ...

Evolutionary Biology Concepts
Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) traits vary among individuals with ...
