- Methodology for building and maintaining enterprise architectures in small and medium enterprisesPublication . Gomes, Ruben David de Sousa; Zacarias, MarielbaEnterprise architectures are used by companies so that they can understand their structure and dynamics in a more extensive and detailed way, allowing them to reduce costs, increase productivity, promote growth and adapt in a rapidly changing business environment. In order to not only survive but gain competitive advantage, enterprises need their architectures to be in sync with their business, which means being as faithful and up-to-date as possible. Current methodologies for developing architectures such as Enterprise Architecture Planning (EAP) are designed for large companies and need to be adapted to be applicable to small and medium enterprises (SMEs). Also EAP develops the business model based in information gathered in interviews and surveys, which means the processes in the model are at an abstraction level that does not reflect the actual actions being performed by individuals. Additionally, current publications in this area don’t cover how these models can be maintained in automated ways. Stemming from these arguments, the main contributions of this research are first, to adapt EAP defining a methodology that can be applied to a SME. Second, to merge EAP with the Business Process and Practice Alignment Methodology (BPPAM) in order to be able to uncover a business process model from actual work practices captured in users’ action logs. And third, to develop automated ways of analyzing and relating the model with these action logs in order to ease the maintenance of the business model. This research was developed and validated in a real organizational setting within the purchasing department of a company in the retail industry. This work concludes with an overview of what was learned; how some problems found could have been prevented; and how the proposed methodology can be improved for future research.
