spsp hoq fast decision analysis

Product Design (a.k.a. Product Conceptual Design)

Step 1:

Establish customer needs and technical specifications using the HOQ

Step 2:

Identify the primary function (intent) of the product.

Step 3:

Find related products and dissect (reverse engineer) these products using FAST.

(primary function, sub-functions)

Step 4:

Develop the Function Structure (main function, sub-functions, etc.) for the product.

Step 5:

Generate solution principles (SPs) for each sub-function; organize SPs in a morphological matrix.

Step 6:

Generate 6-10 alternative product concepts by suitably combining the SPs in the MM.

Steps 7, 8:

Develop a set of selection criteria; generate a utility function (UF) to assess the alternatives in Step 6.

Use the UF to select 1-2 feasible product concepts for further development.
