Abstract: A evolução tecnológica permite-nos dispor de soluções altamente
flexíveis, de fácil acesso com valores de investimento mais baixos, o que leva
a muitas empresas adotarem soluções SaaS (Software como um Serviço) para
suporte aos seus processos de negócio. Hoje em dia, já quase todos os decisores de
estratégias de TI nas organizações são levados a considerar a adoção de SaaS para
suporte aos seus processos de negócio como uma solução de TI, pelos benefícios de
conveniência associados à tecnologia ou competição no mercado. Muitas vezes, os
decisores das estratégias de negócio consideram apenas os incentivos atraentes do
uso de SaaS ignorando os impactos associados às novas tecnologias. É necessário
ter uma visão holística das implicações no desenvolvimento, no fornecimento, na
utilização e operacionalização de SaaS nos diferentes tipos de empresas. A presente
pesquisa adota vários destes fatores de risco, como fatores dignos de avaliação de
impacto do SaaS para comprovar a sua legitimidade com um estudo combinado
quantitativo-qualitativo.2016-09-01T00:00:00ZA Framework for the Evaluation of SAAS ImpactAraújo, VirgíniaVázquez, José AyudeCota, Manuel Perezhttp://hdl.handle.net/10884/14692020-01-25T03:00:39Z2014-05-01T00:00:00ZTitle: A Framework for the Evaluation of SAAS Impact

Abstract: Nowadays the technological progress allows us to have highly flexible solutions, easily accessible with
lower levels of investment, which leads to many companies adopting SaaS (Software-as-a-Service) to
support their business processes. Associated with this movement and considering the advantages of SaaS, it
is important to understand whether work is being developed that is underutilized because companies are
not taking advantage of it, and in this case it is necessary to understand the reasons thereof. This
knowledge is important even for people who do not use or do not develop/provide SaaS, since sooner or
later it will be unavoidable due to current trends. In the near future, nearly all decision-makers of IT
strategies will be forced to consider adopting SaaS as an IT solution for the convenience benefits
associated with technology or market competition. At that time they will have to know how to evaluate
impacts and decide. What are the real needs in the Portuguese market? What fears and what is being done
to mitigate them? What are the implications of the adoption of SaaS? Where should we focus attention on
SaaS offerings in order to create greater value? These are questions we must answer to actually be able to
assess and decide. Often, decision-makers of business strategies consider only the attractive incentives of
using SaaS ignoring the impacts associated with new technologies. The need for tools and processes to
assess these impacts before adopting a SaaS solution is crucial to ensure the sustainability of the
information system, reduce uncertainty and facilitate decision making. This article presents a framework
for evaluating impacts of SaaS called SIE (SaaS Impact Evaluation) which in addition to guidance for the
present research, aims to provide guidelines for the collection, data analysis, impact assessment and
decision making about including SaaS on the organizations strategic plans.2014-05-01T00:00:00ZBusiness and Technical Requirements of Software-as-a-Service: Implications in Portuguese Enterprise Business ContextAraújo, VirgíniaVázquez, José Ayudehttp://hdl.handle.net/10884/14682020-01-25T03:00:36Z2013-11-01T00:00:00ZTitle: Business and Technical Requirements of Software-as-a-Service: Implications in Portuguese Enterprise Business Context
Authors: Araújo, Virgínia; Vázquez, José Ayude
Abstract: Software-as-a-Service (SaaS) is a viable option for some companies bearing their business processes.
There is a considerable adoption rate, with companies already using more than two services for over two
years. However, while some companies have plans to put more business processes supported by these
services in the near future, others do not know if they will. They have several concerns regarding the
software providers’ service level. These concerns are mainly technical and functional issues, service
availability and payment models. There are major changes compared to the traditional software that have
implications on how the software is developed and made available to the users. The existing research
addresses specific aspects and few studies give a broader view of the implications of SaaS for anyone who
develops and provides software, and also for those who consumes it as an end user. What are the real
needs of the Portuguese market? What fears and what is being done to mitigate them? Where should we
focus our attention related to the SaaS offering in order to create more value? Thus, to analyze these
questions four exploratory case studiesare used to assess the possible implications of SaaS on software
developers or software providers based in Portugal and also on end-users.
This article appears in the context of a realistic and deep research that includes the involvement of
managers, leaders and decision makers of Portuguese companies, to realize what actually constitutes a
problem in SaaS and what effectively companies would like to have available in this offer. The results of
this study reveal that SaaS effectively constitutes a very interesting and solid solution for the development
of Portuguese companies, however there is a lack for greater efforts particularly in terms of customization
for each customer (tenant) and integration with the back-end on-premise applications.2013-11-01T00:00:00ZAteliê de Objetos de Aprendizagem: Uma Abordagem para o Ensino de Computação em Cursos TécnicosPereira, Luís Francisco DiasSampaio, Fábio FerrentineOliveira, CarloLapolli, FábioMotta, Cláudiahttp://hdl.handle.net/10884/14332019-11-22T03:01:56Z2010-02-01T00:00:00ZTitle: Ateliê de Objetos de Aprendizagem: Uma Abordagem para o Ensino de Computação em Cursos Técnicos

Abstract: A familiaridade com que os jovens lidam com a tecnologia faz com que muitos
alunos, ingressos em cursos de computação, sintam-se desmotivados ao se deparar
com o nível de abstração dos conteúdos e com os métodos utilizados para transmitilo.
Esta falta de interesse eleva a dificuldade na aprendizagem e a evasão das aulas.
Para minimizar estes efeitos é proposta uma abordagem de ensino onde os aprendizes
possam se engajar em um projeto real, colaborando em e entre grupos para a
criação de objetos de aprendizagem que poderão ser utilizados posteriormente por
outros estudantes da escola.2010-02-01T00:00:00Z
