Mass customisation involves the provision of product variants that fulfil clients’ specific requirements seeking to increase
product values. The configuration process involves a chain of decisions, which needs to be undertaken to create product
variants that meet each client specific requirements. In this paper, this chain of decisions is conceptualized in terms
of customisation units. Each customisation unit encompasses a customisable attribute (e.g. size, colour) and the range
of items offered for this attribute. A design science approach was adopted in this investigation. In this approach, knowledge
is produced by creating and testing a solution, which provides practical and theoretical contributions. A method
is proposed to analyse and improve the configuration process by conceptualizing this process as a tree diagram. The
proposed method is used to analyse the configuration process developed by organisations of the house-building sector
based in the U.K. and Brazil: a manufacturer of floor tiles, contractors, and registered providers. These analyses
enabled a comparison of the distinct configuration processes adopted. In addition, problems associated to the configuration
process (such as burden of choice) and opportunities for improvements were also identified. Finally, alternative
chains of decision were also devised based on these analyses to address the problems identified.
