The paradigm of Open Source Software (OSS) has revolutionized the way in which the software is used, marketed and distributed. Due to its strategic importance, in recent years, public administrations have defined plans for the promotion and strengthening of Information and Communication Technologies (ICT) based on the use of OSS. These strategies have been recognized benefits and a wide social repercussion, given that the open and collaborative paradigm of the OSS phenomenon allows the use and diffusion of ICTs at all social levels. However, it limits the exploitation of the benefits of adopting OSS in the public, private industry and in the Ecuadorian society in general, due to shortcomings in the identification, assessment and risk management, in addition to good practices and adoption, the motive this project is to make a systematic literature review of the OSS adoption, based on Kitchenham and Charters methodological guide; this guide consists in a technique based on empirical research, which requires following a protocol to collect the literature on existing research, related to the free software adoption by organizations, for obtaining relevant references of success, failure, risk, benefits and barriers factors of adoption, in order to determinate the current situation of the OSS use in Ecuador.

The purpose of the following study is present the MOOC Information System Generic Architecture as a result of the analysis of quality characteristics found in the literature concerning of MOOC, and the application of the Discovering Hybrid ARchitectures by Modelling Actors (DHARMA) method based on the use of i∗. Generic Architecture refers to the identification of MOOC system actors, the services that must be covered by each one and the relationships between them. The i∗ diagrams allow identifying strategic needs for which a MOOC Information System is required in an organization (pedagogical approach), and express them indicating the specific services that the system must provide (technological approach), grouping related services in atomic domains. Finally, this study shows how the Generic Architecture will guide the future construction of a MOOC software quality model with ISO/IEC 25010 as an instrument to facilitate a systematic and practical evaluation of those characteristics that guarantee the quality and effectiveness of MOOC in the generation of learning.

Current software systems are hybrid in nature. They are built by integrating third party Off-The-Shelf (OTS) components with preexisting legacy and bespoke custom-made software. In such systems, components are usually arranged into layers (e.g., hardware platform, operating systems and database layers, among others) to allow for their operation and interaction. Although several methods have been proposed to support OTS component selection, the truth is that in many cases the process is driven by political and other non-technical aspects, considering components as independent and isolated. Because of this, relevant stakeholder's requirements and concerns, as well as the implications that the selection of a particular component may bring to the system architecture, are simply ignored. In the worst case this may lead to the selection of unsuited or inappropriate components and eventually to miscarried projects, but more often to situations in which projects froze due to lack of stakeholders' agreement in relation to the newly created architectural scenario and some of its emerging requirements. In this paper we address these issues and present a proposal that uses software quality models as framework to support the negotiation of both initial and emerging requirements and the reconciliation of stakeholders' concerns. The approach considers components at different layers of system's architecture. The advantages of the proposal are illustrated with a real case conducted in a banking organization.
