   Morphology of design 

   Morphology of design refers to the study of the chronological structure of design projects. The following phases are usually involved in any design project:
a.      Feasibility study
b.      Preliminary design
c.      Detailed design
d.     Production planning
e.      Distribution planning
f.        Consumption planning
g.     Retirement planning

Various steps involved in each phase of Morphology of design  are discussed below:

a. Feasibility study: Provides a set of useful solutions to a problem. 
Various steps are;
i. To demonstrate that the original need has current existence.
ii.To explore the design problem and identify elements
like parameters,constraints, major design criteria etc.
iii. To conceive a number of possible solutions.
 iv. To sort out potentially useful solutions on the basis of physical 
reliability, economic worthwillness, and financial feasibility.



b. Preliminary design: Establishes which the best design concept is. Various 
steps involved Preliminary design are;
      
i.To subject each alternative solution to order of magnitude 
analysis until one is proved to be the best.
ii.To initiate synthesis studies for establishing the fineness of the 
range within which the major design parameters must be controlled.
iii.To study how the design will meet consumer’s taste, how it will match 
with products of competitors, whether scarce and critical raw materials will 
continue to be available, rate of obsolescence.
iv.The rate of deterioration of performance with corrosion, wear fatigue, etc.
v. To test the critical aspects of the design in order to validate the design 
concept and provide information for subsequent phases.



c. Detailed design: Furnishes the engineering description of a feasible design.
Various steps fo Detailed design are;

 i.To develop an overall, provisional synthesis as a master layout.
ii.To prepare specifications of components.
iii.To initiate experimental design by constructing models to check out untried ideas.
iv.To test prototypes and using information obtained as basis of redesign 
and refinement.
