SoS is an approach that allows the offering of unique capabilities through the integration of existing systems. SoS approach can be observed in several domains such as military, logistics, transportation, healthcare etc. Despite the great interest in this field in the last years, many problems are still open. Since the systems that compose an SoS are independent and have individual objectives,one of the most critical challenges is enabling the governance of this class of system. Therefore, this paper presents an investigation on the factors that should be taken in consideration when implementing SoS governance. To do so, we carried out a survey with professionals of a Brazilian public organization.

Community smells refer to unfavorable socio-technical patterns in software development community structures that might exist and lead to a variety of issues, such as loss of key information in any software ecosystem (SECO). These ecosystems also involve power relationships, which have an impact on products and bring challenges. This work proposes to investigate and analyze the relationship between community smells and power relationship dynamics in proprietary software ecosystems (PSECO). By identifying the community smells that may exist in SECO, community members and academics can improve their knowledge and process management, software quality, and the development process, among others.

A indisponibilidade de sistemas que compóem uma plataforma de ecossistema de software (ECOS) proprietário, aqueles que são protegidos pela propriedade intelectual, prejudica produtividade e receita, além de provocar danos ao ECOS e à imagem da organização. Neste cenário, manter uma plataforma tecnológica mitigando os riscos de incidentes (interrupção não planejada de um serviço) é uma das atividades existentes para sustentar o ECOS. Este trabalho tem como objetivo desenvolver e avaliar uma abordagem baseada em um processo para gestão de incidentes visando apoiar a equipe de gerenciamento de TI na avaliação da manuteção da plataforma de um ECOS proprietário.
