This paper states an approach for the operationalization of a solution architecture model, as an integral part of the development process and the applications maintenance. The proposed approach has been put into practice in a Company from the financial sector.

Recently, the concept of solution architecture, has emerged as a better practice (little explored and documented) and it is being used in the execution of initiatives related with the development of technology solutions cycle, also it interacts collaboratively with other better management practices as software and enterprise architecture.
