The alignment of business issues with technological service-oriented solutions has proven to be a crucial aspect of modern business development. In this regard, the provision of methods to solve the gap between business and technology becomes absolutely necessary. This paper presents a proposal to systematize that leap by defining a development method centred on the concept of Architecture. The use of different architectural models at different levels of abstraction (along with the definition of model transformations between them) allows for the establishment of a trace between the business-level elements and software elements that are derived from them. Key benefits of our proposal are, on the one hand, the provision of a method for business-technology alignment and, on the other hand, the definition of a new model to represent the structure of a business. This proposal has been refined and validated using the case of an information system for the management of paediatric percentiles
