Producer’s capacity
The Kano model is inherently customer-driven, i.e., it focuses exclusively on
addressing the concerns of customers (Sireli et al., 2007). As a decision-making
tool used by engineers, the Kano model fails to account for the producer’s concerns
in terms of the capacity to fulfill the CNs. Cost constraints are usually
accommodated by the product development team based on expertise, such
that the product will only include those features that are affordable to the producers
(Matzler and Hinterhuber, 1998). In practice, without accurate cost estimation,
such an assumption seldom holds true. Lai et al. (2004) propose
a linear cost function to constrain the selection of product features in product
development. Tan and Shen (2000) propose an approximation transformation
function based on Kano analysis to adjust the improvement ratio of customer
attributes. However, these cost models are primitive and are inadequate to reflect
the complexities of design and manufacturing costs. From an engineering
perspective, engineers have to seek for a leverage of the customer-perceived
value and the producer’s capacity.
