Previous issue date: 2017-08-29 / This dissertation proposes and evaluates a method to improve the requirements elicitation
process, according to the needs identified in the business processes, and can support any process
of surveying customer needs. For this, gaps were sought in the traditional software development
processes and analyzed the points where Information Architecture could bring quality gains.
The main justification for improving the requirements elicitation process was the recognition
of the fact that traditional processes do not capture the full requirements of an application
context. The applicability of the proposed methodology was verified by means of an action
research with the requirements analysis of a software development company. In addition to the
effectiveness of the method, it was also verified improvements in the quality of information
previously collected by the revisitation to the client's environment. / A presente disserta????o prop??e e avalia um m??todo para aprimorar o processo de elicita????o de
requisitos, conforme as necessidades identificadas nos processos de neg??cio, podendo apoiar
qualquer processo de levantamento de necessidades de clientes. Para tanto, buscou-se lacunas
nos processos tradicionais de desenvolvimento de software e analisados os pontos em que a
Arquitetura da Informa????o pudesse trazer ganhos de qualidade. A principal justificativa para
aprimorar o processo de elicita????o de requisitos foi o reconhecimento do fato de que os
processos tradicionais n??o capturam a totalidade dos requisitos de um contexto de aplica????o. A
aplicabilidade da metodologia proposta foi verificada por meio de uma pesquisa-a????o junto a
analistas de requisitos de uma empresa de desenvolvimento de software. Al??m da efetividade
do m??todo, tamb??m foram verificadas melhorias na qualidade das informa????es anteriormente
colhidas pela revisita????o ao ambiente do cliente.

Previous issue date: 2016-02-29 / The quantity and diversity of present processes in large organizations are huge.
Considering a context of high productivity and high turnover, cost of employees for
the information and knowledge necessary to perform their tasks as well as the loss of
knowledge, causes significant damage. However, Knowledge Management (KM)
provides a horizon in this field and may represent a competitive advantage. The
institutions that create new knowledge in a sustainable manner and spread
throughout the organization have the capacity to innovate, improving processes and
bypassing any crises. Internal services, demands between units of an institution,
often represent bottlenecks in performance, caracterized for errors, delays and low
quality / efficiency, among others, with a significant impact on the final product /
service. A methodology that addresses these services can be a way for institutions
such as governments meet the challenge of raising the standard of service to
customers and citizens. Ontologies contribute to this optical in that create and
conceptual relationships on the knowledge models. From them, inferences can be
made both by humans and by machines, facilitating searches, maximizing
disambiguations and establishing clear standards of communication. Thus, the
present study had the vision to contribute to improving the efficiency and
effectiveness in public administration, using the premises of the Service Charter with
the main objective to describe these internal services in the form of an ontology. Was
used as a research focus a representative public bank of the indirect administration
and among the main findings, there was satisfactory use of a new methodology for
creating ontologies, creating an ontology for the intended context (OntoCSI), the
creation of application wiki pilot that showed the basic elements for collaborative
construction of the Internal Services Charter template and the approval of this
interface with experts and other stakeholders. / A quantidade e a diversidade de processos presentes nas grandes organiza????es s??o
enormes. Considerando um contexto de alta produtividade e de alta rotatividade, o
custo dos funcion??rios para obter a informa????o e o conhecimento necess??rios para a
execu????o de suas tarefas, bem como a perda de conhecimento, origina preju??zo
significativo. Entretanto, a Gest??o do Conhecimento (GC) fornece um horizonte
neste campo e pode representar vantagem competitiva. As institui????es que criam
novos conhecimentos de forma sustent??vel e os disseminam por toda a organiza????o
possuem a capacidade de inovar, melhorando os processos e contornando
eventuais crises. Os servi??os internos, demandas entre as unidades de uma
institui????o, frequentemente representam gargalos em seu desempenho,
tangibilizados por erros, atrasos e baixa qualidade/efici??ncia, entre outros, com
reflexos significativos no produto/servi??o final. Uma metodologia que aborde estes
servi??os pode ser uma via para institui????es, como os governos, cumprirem o desafio
de elevar o padr??o dos servi??os prestados aos clientes e aos cidad??os. As
ontologias contribuem para esta ??tica na medida em que criam modelos conceituais
e de relacionamentos sobre o conhecimento. A partir delas, podem ser realizadas
infer??ncias tanto por humanos quanto por m??quinas, facilitando buscas,
maximizando desambigua????es e estabelecendo padr??es claros de comunica????o.
Assim, a presente pesquisa teve a vis??o de contribuir com a melhoria da efici??ncia e
da efic??cia na administra????o p??blica, utilizando as premissas da Carta de Servi??os
com o objetivo principal de descrever estes servi??os internos sob a forma de uma
ontologia. Utilizou-se como foco de pesquisa um banco p??blico representativo da
administra????o indireta e, dentre os principais resultados, houve satisfat??ria utiliza????o
de nova metodologia para a cria????o de ontologias, a cria????o de uma ontologia para
o contexto pretendido (OntoCSI), a cria????o de aplica????o wiki piloto que mostrou os
elementos b??sicos para constru????o colaborativa do modelo de Carta de Servi??os
Interna e a aprova????o desta interface junto a especialistas e outras partes
interessadas.

Previous issue date: 2015-02-24 / O presente trabalho teve como objetivo elaborar uma lista de recomenda??es para o
site do Instituto do C?rebro da Universidade Federal do Rio Grande do Norte com
?nfase na identifica??o de falhas na usabilidade e na arquitetura da informa??o, por
meio da aplica??o de t?cnicas do design com usu?rios da institui??o. A partir da
aplica??o das t?cnicas Cardsorting, aplicada com um grupo de seis pessoas
(professor, t?cnicos administrativos e aluno da p?s-gradua??o); entrevistas com o
diretor do Instituto do C?rebro e com secret?rias da gradua??o e p?s-gradua??o;
Avalia??o Cooperativa, aplicada de duas formas: em grupo, com um grupo formado
por seis pessoas que s?o integrantes do corpo t?cnico do Instituto do C?rebro e
individualmente, com oito usu?rios (alunos da p?s-gradua??o e t?cnicos
administrativos do Instituto do C?rebro da UFRN) que desempenharam tarefas que
s?o frequentemente realizadas por usu?rios pertencentes ao p?blico-alvo no site do
Instituto do C?rebro. Ap?s cada sess?o da Avalia??o Cooperativa Individual foi
aplicado um question?rio de satisfa??o do usu?rio sobre sua percep??o a respeito
da usabilidade e da utilidade do site do ICe. Concluiu-se, portanto que, por meio da
an?lise dos resultados e da triangula??o dos dados obtidos em cada uma das
t?cnicas aplicadas com usu?rios na presente pesquisa, foram verificados, dentre
outros, problemas relacionados ? utiliza??o inadequada de elementos de interface,
navega??o, rotulagem de alguns termos do menu, e ainda, a aus?ncia de campo de
busca e integra??o com as redes sociais ? al?m da aus?ncia, posicionamento e
formata??o inadequada de informa??es que seriam de alta relev?ncia para os
usu?rios. Por fim, ? apresentada uma lista de recomenda??es que poder? ser
utilizada em futuro redesign da interface com vistas ? melhoria da arquitetura da
informa??o e usabilidade do site do Instituto do C?rebro da Universidade Federal do
Rio Grande Norte. / The objective of the current piece of research presents was draw up a list of
recommendations for the site of the Instituto do C?rebro da Universidade Federal do
Rio Grande do Norte, with an emphasis on fault identification in usability and
information architecture, through the application of design techniques with users of
the institution. From the use of the following techniques: Cardsorting, applied to a
group of six people as target public, such as professor, administrative technicians
and graduate student of the institution; Interviews, carried out with the director of the
Instituto do C?rebro, secretaries of the undergraduate and graduate courses;
Cooperative Evaluation applied in two ways: in group and individually. The evaluation
in group was fulfilled in four sessions that occurred with a group composed of six
people who are part of the technical staff of the Instituto do C?rebro. In the Individual
Cooperative Evaluation, eight users (graduate students and administrative
technicians of the Instituto do C?rebro da UFRN) performed tasks which are
frequently fulfilled by users from the public target in the site of the Instituto do
C?rebro. After each session of the Individual Cooperative Evaluation, a questionnaire
of the user?s satisfaction was used about his or her perception in regard to the site
usability and utility of the mentioned institute site. Therefore, it was concluded that,
by means of the analysis of the results and the triangulation of the obtained data in
each one of the techniques applied with the users, in the present piece of research,
problems were verified, among others; all related to the unsuitable use of the
interface elements, navigation, labeling of some menu terms, and still, the lack of
search space and integration with the social networks ? besides the lack, positioning
and inappropriate formatting of information that would be of high relevance to the
users. Finally, a list of recommendations is presented and this can be used in a
future interface redesign with the goal to improve the information architecture and the
usability of the site of the Instituto do C?rebro da Universidade Federal do Rio
Grande do Norte.

Previous issue date: 2016-02-29 / The Requirements Elicitation is a process dedicated to understanding the needs of customers and users, and transform these needs into system development projects. To capture such needs the requirements engineer needs to interact with business people and the most diverse areas. This interaction requires intense communication, and is greatly affected by differences in vocabulary and interpretation that exists between the business team and the team of system developers. However, the use of Architecture Information methods and ontologies bring new alternatives to treat such problems. The Architecture Information method MAIA appears to be adherent to the Requirements Elicitation, providing new insight into the process. Therefore, studies have been identified which address the use ontologies and MAIA method that can be used to support the requirements specification. The main objective of this study is to propose the
requirements elicitation in cycles (REC) model, creating a new approach to the system specification, which ensures a complete, consistent and unambiguous requirements document, and which allows automated content support. This approach is based on a set of best practices aimed at improving support for communication between teams and consequently the requirements survey process as a whole. / Levantamento de Requisitos ?? um processo dedicado a compreender as necessidades de clientes
e usu??rios, e transformar estas necessidades em projetos de desenvolvimento de sistemas. Para
capturar tais necessidades, o engenheiro de requisitos precisa interagir com pessoas de neg??cio
e das mais diversas ??reas. Essa intera????o requer intensa comunica????o, e ?? bastante afetada pelas
diferen??as de vocabul??rio e interpreta????o que existe entre a equipe de neg??cio e a equipe de
desenvolvedores do sistema. O uso de m??todos de Arquitetura da Informa????o e de ontologias
trazem novas alternativas para tratar tais problemas. O m??todo de Arquitetura da Informa????o
MAIA mostrou-se aderente ao Levantamento de Requisitos, possibilitando uma nova vis??o sobre
o processo. Foram identificados estudos que abordam o uso de ontologias e do m??todo
MAIA que podem ser usados para apoiar o levantamento de requisitos. O objetivo principal
deste trabalho ?? propor o modelo de Elicita????o de Requisitos em Ciclos (ERC), criando uma
nova abordagem para a especifica????o de sistemas, que garanta um documento de requisitos
completo, consistente e n??o amb??guo, e que permita suporte automatizado de conte??do. Esta
abordagem ?? baseada em um conjunto de melhores pr??ticas que visam melhorar o suporte a
comunica????o entre as equipes e, consequentemente, o processo de Levantamento de Requisitos
como um todo.

Previous issue date: 2014-12-04 / informa??o de reposit?rios institucionais, optou-se pelo estudo de caso do Reposit?rio Institucional da Universidade Federal do Rio Grande do Norte. Assim, questionou-se durante a pesquisa se a arquitetura da informa??o e o design da interface do Reposit?rio Institucional da UFRN proporcionam a usabilidade para alunos de gradua??o, p?s-gradua??o e bibliotec?rios da universidade, atendendo desse modo, ao interesse institucional de promover transpar?ncia e acesso livre ?s informa??es produzidas pelas pesquisas desenvolvidas. Estabeleceu-se, como hip?tese da pesquisa, que a arquitetura da informa??o da interface do Reposit?rio Institucional da UFRN, na vers?o 1.8.1, desfavorece a usabilidade na execu??o das tarefas pelos grupos de usu?rios do sistema. A coleta de dados foi realizada por meio da aplica??o das t?cnicas de Avalia??o Cooperativa, com dez alunos de p?s-gradua??o, e Testes de Usabilidade do sistema do RI/UFRN, com um grupo representativo de usu?rios do sistema: dez bibliotec?rios e dez alunos de gradua??o. Os participantes realizaram tarefas representativas ? ?Busca? e ?Submiss?o? de um artigo cient?fico. Al?m das t?cnicas de avalia??o, os participantes do Teste de Usabilidade responderam ao question?rio s?ciodemogr?fico e ao question?rio de satisfa??o, adaptado de Questionnaire for User Interaction Satisfaction ? QUIS (SHNEIDERMAN, 1998). A partir dos resultados obtidos por meio da Avalia??o Cooperativa com alunos de p?s-gradua??o e dos Testes de Usabilidade com alunos de gradua??o e bibliotec?rios, foram encontrados problemas de usabilidade e arquitetura da informa??o presentes no sistema do Reposit?rio Institucional, tais como: rotulagem; tamanho da fonte; nomenclatura dos bot?es e falta de feedback do sistema. Ap?s a identifica??o dos problemas apontados pelos usu?rios, foram atribu?dos graus de severidade e elaborada uma lista de recomenda??es ergon?micas. Acredita-se que o redesign da interface do Reposit?rio Institucional da UFRN, relativo ?s tarefas apresentadas na pesquisa, que considere que os aspectos de usabilidade e de arquitetura da informa??o, supracitados, contribuir?o para melhoria no acesso e visibilidade das informa??es. / In order to identify the possible problems of usability and information architecture of the institutional repositories, the case study of the Institutional Repository of the Federal University of Rio Grande do Norte was chosen. Therefore, during the survey, it was questioned if the information architecture and the interface design of the UFRN Institutional Repository provide usability with graduate students, undergraduate students and librarians so as to meet the institutional interest to promote transparency and open access to the information produced by the pieces of research carried out at the university. As research hypothesis, it was established that the information architecture of the UFRN Institutional Repository interface, version 1.8.1, disadvantage usability in performing the tasks by system user groups. Data collection was carried out by applying the techniques of Cooperative Evaluation with ten graduate students and Usability Testing of the UFRN/ IR system, with a representative group of system users: ten librarians and ten undergraduate students. The participants performed representative tasks ? ?Search? and ?Submission? of a scientific article. Besides the evaluation techniques, the Usability Testing participants answered a social and demographic questionnaire as well as the satisfaction?s questionnaire, adapted of Questionnaire for User Interaction Satisfaction ? QUIS (SHNEIDERMAN, 1998). From the results obtained by means of the Cooperative Evaluation with graduate students and the Usability Testing with undergraduate students and librarians, problems of usability and information architecture were found in the Institutional Repository, such as: labeling, font size, nomenclature of the buttons, lack of the system feedback. After identifying the problems pointed out by the users, severity levels were assigned and a list of ergonomic recommendations was outlined. The redesign of the UFRN Institutional Repository interface about the areas related to the tasks presented in the research, that considers the aspects of usability and information architecture, mentioned above, will contribute to an improvement in the access and visibility of information.
