Classification | Analyzing/Trending (AT) |
The value analysis technique analyzes the functionality of a product, states an estimated cost for each function, and demonstrates a function as compared with that of a competitor's. This technique, therefore, forces an assessment of the manufacturing processes, parts and materials, and design features of a product.
To identify needed product improvements.
To lower product costs.
To prioritize product redesign activities.

The construction of the value analysis table may reflect a different set of factors.
The primary concern is to determine functions that have a high cost associated with them. These functions often call for a redesign priority.
Competitors' superior designs must be considered in all redesign efforts.
STEP 1 First, a customer satisfaction survey is completed to collect the customers "wants" or expectations. See example Designing a Better Mouse Trap.
STEP 2 As the second step, design engineering and manufacturing examine a number of competitors' products. The team checks for improved functionality, superior designs, and innovation.
STEP 3 A value analysis form is used to list the product's functions and subfunctions. Customer "wants" and competitor data are also filled in.
STEP 4 For every function and subfunction, the estimated cost and percent of total product cost are recorded.
STEP 5 The last step determines the functions that are strong candidates for redesign on the basis of cost and competitors' superior designs.
STEP 6 The completed value analysis form is reviewed, dated, and given to the process owners.
