Analysing increase of functionality and complexity in integrated product architectures

Nowadays, product designers find difficulties and uncertainties when assessing how complex a product will be when introducing new functionalities or when integrating multiple functionalities into a single component. In this paper, the impact of functionality on complexity is quantitatively analyzed in two different case studies: one regarding a set of valves to study how complexity is affected when adding new functionalities, and another one related to three alternative designs of computer mice that features different degrees of functional integration.
