His father was the economist Philip Green Wright and his brothers were the geneticist Sewall Wright and the political scientist Quincy Wright. He graduated from Lombard College and Massachusetts Institute of Technology. He served in World War I. In 1936, he published an important paper entitled "Factors affecting the costs of airplanes" which describes what is known as '' Wright's law'' or experience curve effects. The paper describes that "we learn by doing" and that the cost of each unit produced decreases as a function of the cumulative number of units produced. He served as administrator of the Civil Aeronautics Administration during 1944–1948. When President Truman announced Wright’s resignation as Administrator of Civil Aeronautics on January 16, 1948, the ''New York Ti ...

Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education City, Qatar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Experience Curve Effects
In industry, models of the learning or experience curve effect express the relationship between experience producing a good and the efficiency of that production, specifically, efficiency gains that follow investment in the effort. The effect has large implications for costs and market share, which can increase competitive advantage over time. History: from psychological learning curves to the learning curve effect An early empirical demonstration of learning curves was produced in 1885 by the German psychologist Hermann Ebbinghaus. Ebbinghaus was investigating the difficulty of memorizing verbal stimuli. He found that performance increased in proportion to experience (practice and testing) on memorizing the word set. (More detail about the complex processes of learning are discussed in the Learning curve article.) Wright's law and the discovery of the learning curve effect This was later more generalized to: the more times a task has been performed, the less time is required ...

Learning Curve
A learning curve is a graphical representation of the relationship between how Skill, proficient people are at a task and the amount of experience they have. Proficiency (measured on the vertical axis) usually increases with increased experience (the horizontal axis), that is to say, the more someone, groups, companies or industries perform a task, the better their performance at the task.Compare: The common expression "a steep learning curve" is a misnomer suggesting that an activity is difficult to learn and that expending much effort does not increase proficiency by much, although a learning curve with a steep start actually represents rapid progress., see the "Discussions" section, Dr. Smith's remark about the usage of the term "steep learning curve": "First, semantics. A steep learning curve is one where you gain proficiency over a short number of trials. That means the curve is steep. I think semantically we are really talking about a prolonged or long learning curve. I kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
