2. What is Value Analysis? “A systematic method of comparison for determining the option(s) that best meet a set of required or desired criteria.” “A systematic and critical assessment of every features of a product to ensure that the cost is no greater than is necessary to carry out the functions”

5. Value Analysis Steps To Evaluate Alternate Designs (1) Rank-order of design goals (2) Assign weighting factors to design goals (3) Rating factors to alternate designs (4) Decision Matrix

6. Value Analysis Example 1 Select a Computer System Design Goals: Performance, Minimum maintenance, Aesthetics, Minimum cost, Availability of parts, Ease of use, Versatilities, Portability Assign weighting factors to design goals: Categories of significance e.g. Critical (71-100), Important (31-70), Optional (1-30) Rating Factors of alternate designs: For example: Excellent (10), Good (8), Satisfactory (6), Mediocre (4), Unsatisfactory (2), Failure (0)
