[2] [3] [4] It was written by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology and published in 1956 in Psychological Review. It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller's law.
Product design is the process of creating new products for businesses to sell to their customers. [1] It involves the generation and development of ideas through a systematic process that leads to the creation of innovative products. [2] Thus, it is a major aspect of new product development. Product Design Process:
A design sprint is a time-constrained, five-phase process that uses design thinking with the aim of reducing the risk when bringing a new product, service or a feature to the market. The process aims to help teams to clearly define goals, validate assumptions and decide on a product roadmap before starting development. [ 1 ]

Human-centered design has its origins at the intersection of numerous fields including engineering, psychology, anthropology and the arts. As an approach to creative problem-solving in technical and business fields its origins are often traced to the founding of the Stanford University design program in 1958 by Professor John E. Arnold who first proposed the idea that engineering design should ...
Average physical product (APP), marginal physical product (MPP) In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming ...
The average product of labor (APL) is the total product of labor divided by the number of units of labor employed, or Q/L. [2] The average product of labor is a common measure of labor productivity. [4] [5] The AP L curve is shaped like an inverted “u”. At low production levels the AP L tends to increase as additional labor is added.
If the firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown [1] [2] [3] that at a particular level of output, the firm has economies of scale (i.e., is operating in a downward sloping region of the long-run average cost ...
