IntroductionSolution architectures are essential for companies to enable value generation and increase the efficiency of processes related to design and implementation of technology solutions (Arango Serna et al., 2015). As Fig. 1 shows, a technology AbstractIn the dynamic environment nowadays, companies require continuously to implement and improve their technology solutions to respond to new technology tendencies, business requirements, and enterprise architecture initiatives. This transformation is supported by solution architectures, which contain solution components that are implemented to respond to company's requirements. As a consequence, the ability to analyze solution architectures financially becomes significantly essential to determine their costs, benefits, profitability, and the impact of the unpredictable events that can derive positive or negative consequences in technology investments. However, since most current financial models address overall IT investments, it is difficult to calculate the detailed and precise financial indicators required for solution architectures and their components. Consequently, financial variables can be omitted, and financial indicators can be limited and insufficient to analyze advantages, disadvantages, and risks associated with solution architectures and their components. With this in mind, our study presents an innovative cost-benefit model specifically for solution architectures. To define, design and evaluate our model, we adopted the Design Science Research paradigm. As a result of the model's evaluation, we determined that our model calculates specific indicators related to alternatives and components which can reduce the risk omitting of variables while increasing flexibility for comparing alternatives and provision of support for technology investment decisions.
