product evolution theory
the product evolution theory in p>TRIZ divides the product evolution process into four stages: infancy, growth period, maturity period and withdrawal period. For the products in the first two stages, enterprises should increase investment and make them mature as soon as possible, so that enterprises can obtain maximum benefits;
For mature products, enterprises should study their alternative technologies, so that products can acquire new alternative technologies to cope with future market competition; Products in the withdrawal period, corporate profits have dropped sharply, and should be eliminated as soon as possible. These can provide concrete and scientific support for enterprise product planning.
