Metodo March

INTORDUCCION
Como se mencionó, los modelos prescriptivos además de describir, dan pautas para desarrollar cada una de las fases y etapas del proceso de diseño. En esta categoría existe una granvariedad de propuestas, siendo las más conocidas las de Archer, VDI21, March, Pugh y Pahl y Beitz

MODELO MARCH
VDI was criticized in the design world because it seems to be based on a problem-focused,rather than a solution focused approach. It therefore runs counter to the designer’s traditional ways of thinking
A more radical model of the design process, which recognizes the solution –focusednature of design thinking, has been suggested by March 1984. He argued that the two conventionally understood forms of reasoning. Inductive and deductive only apply logically to the evaluative andanalytical types of activity in design. However, the type of activity that is most particularly associated with design is that of synthesis, for which there is no commonly acknowledged form of reasoning.March drew on the work of the philosopher Peirce to identify this missing concept of abductive reasoning according to Peirce
DEDUCTION proves that something must be;
INDUCTION shows that somethingactually is operative
ABDUCTION suggest that something may be
It is this hypothesizing of what may be, the act of synthesis that is central to design. Because it is the kind of thinking by which designs aregenerated or produced, March prefers to it productive reasoning. Thus his model for a rational design process is a PDI MODEL Production Deduction Induction
In this model the first phase, ProductiveREASONING, draws on a preliminary statement of requirements, and some presupposition about solution types in order to produce, or describe, a design proposal. From this proposal and established theoryit is possible deductively to analyze, or predict, the performance of the design. From these predicted performance characteristics it is possible inductively to evaluate further suppositions or...
