Por outro lado, o grau de densidade de testes dos requisitos do sistema sofre influência da forma que esses requisitos são interpretados. Uma proposta para sistematizar o processo de criação de casos de teste encontra-se no uso de uma rede Bayesiana que modela a arquitetura de testes a ser implementada, aliada a uma ponderação estatística de riscos a cenários. A rede é muito adequada a problemas não determinísticos e que envolvam riscos. Aliada ao uso da rede Bayesiana, essa sistematização engloba o critério de adequação, cujo objetivo é minimizar o impacto da cobertura de requisitos. Cada requisito do sistema é interpretado segundo critérios pré definidos. Como produto final desta proposta sistêmica, além do ferramental gráfico que possibilita a descrição dos casos de testes segundo uma seqüência lógica e simulação de cenários, têm-se uma matriz que reúne todos os casos de testes obtidos da rede e demais oriundos da análise dos requisitos, segundo o enfoque do critério de adequação. O estudo experimental sinaliza um incremento de quatro vezes e meio na densidade de testes de requisitos comparativamente a técnica tradicional. Na fase de análise há uma tendência de redução de esforço em torno de um quarto. Um interessante resultado dessa técnica sistematizada, está na identificação de cenários não previstos pelos requisitos o que vem agregar na atualização da documentação de design / Abstract: The task of writing software use cases is in essence non deterministic and therefore involves risks. On the other hand, the coverage level of requirements depends the way of document requirements are interpreted.In order to bring a systematic approach in developing software use cases, the Bayesian network technique helps supporting with this problem. The current software test architecture is modeled in a graphical way, adding scenario simulation and risk statistic. The network addresses very well risks and non deterministic scenarios.Along with the Bayesian Network , the proposed systematic approach encompasses the adequacy criteria which main goal is to improve requirements coverage. Each system requirement is interpreted according to well defined criteria. A matrix will be the final product, as a result from the current systematic approach. All use cases obtained from the network and those discovered thanks of adequacy criteria can be seen together. In addition this, the technique allows scenarios simulation. The experimental results show an increase of four times and half in requirements coverage, as compared against the traditional technique. In the analysis phase , there is a trend of reducing the effort by a factor of 4.One interesting result using this technique is the amount of new scenarios identified. Most of them are not properly described in the requirement document. This brings a powerful tool to add value in updating the design document / Mestrado / Engenharia de Software / Mestre em Ciência da Computação

La presente investigación, plantea resolver la problemática presentada en la Congregación Misión Cristiana Casa de Dios donde existen deficiencias en cuanto a miembros (personas) que no son adoctrinadas debido a la carencia de personal capacitado. Para ello nos preguntamos ¿de qué manera se apoyará a la enseñanza bíblica básica de la congregación Misión Cristiana Casa de Dios? La solución tecnológica propuesta es la implementación de un Software Interactivo que transmite la enseñanza bíblica básica de la congregación “Misión Cristiana Casa de Dios”, ya que además se lograría la inclusión de las personas de la congregación con dificultad de conocimiento en la sociedad al tenerlas mejor preparadas para evangelizar a otras personas externas a la congregación. La solución tiene como principal objetivo apoyar a la enseñanza bíblica básica de la congregación Misión Cristiana Casa de Dios a través de la implementación de un software interactivo. En cuanto a la metodología, se optó por utilizar el Proceso Unificado Ágil (AUP) para el desarrollo de software y la metodología activa para la enseñanza. Se tomará un grupo experimental de 32 personas a los que se les aplicará un pre y post test, recopilando datos en entrevistas, observación, análisis y para el procesamiento de estos datos, la herramienta de Ms Office Excel. Finalmente se concluye que el Software Interactivo contribuyó a realizar un mejor apoyo a la enseñanza bíblica de la congregación Misión Cristiana Casa de Dios.

Actualmente, un 15% de las personas discapacitadas son excluidas de la vida social y cuentan con un déficit en su calidad de vida. 0,25% de estos niños padecen Parálisis Cerebral Infantil, cuyas características principales son la dificultad en el habla y limitación motora. En el área de Hospitalización de la Clínica, se cuentan con 25 pacientes habiendo una clara diferencia respecto al número de enfermeras encargadas, el tiempo dedicado a la terapia del lenguaje es mínimo y no se cuentan con herramientas adecuadas para reforzar el mismo. El presente proyecto tiene como objetivo mejorar la capacidad de comunicación de los pacientes con parálisis cerebral infantil, para ello se implementó un Software Interactivo utilizando un Sistema de Electromiografía Superficial, el cual capta las señales eléctricas de 3 movimientos básicos de la mano, con los cuales se controlará el puntero y poder navegar por el Software; para el desarrollo de este se utilizó la metodología MPIU+a. Como resultado se obtuvo una herramienta de comunicación accesible y posible de usar por los pacientes, aumentando el tiempo de reforzamiento de las terapias de lenguaje y además se logró aumentar el Índice de Barthel, indicador del grado de independencia.

Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Software development is a relatively young science and involves certain tools, techniques, documentation aids and processes that are applied to deliver a software project. As hardware, software and business needs advanced, so did the processes used in managing software development. It is a dynamic and complex process and each development environment or project has its own unique characteristics. For this reason the methodologies followed during the development process is very often debated. Software development teams have a wide array of methodologies to choose from. The development team usually decides what the key success factors are to deliver a software product, and then examines each one within the framework of a list of potential methodologies. This way the team can compare which methodology would best suit their needs. Factors used to evaluate which methodology to follow, includes the size of the project team, rate of expected changes, the primary goal of the project, how requirements will be managed, communication structures that will be followed, the nature of the relationship with the customer, and the organisational culture in the customer organisation. This research report takes a comparative look at Waterfall methods versus Agile methods.

The reuse of software units, such as classes, components and services require professional knowledge to be performed. Today a multiplicity of different software unit technologies, supporting tools, and related activities used in reuse processes exist. Each of these relevant reuse elements may also include a high number of variations and may differ in the level and quality of necessary reuse knowledge. In such an environment of increasing variations and, therefore, an increasing need for knowledge, software engineers must obtain such knowledge to be able to perform software unit reuse activities. Today many different reuse activities exist for a software unit. Some typical knowledge intensive activities are: transformation, integration, and deployment. In addition to the problem of the amount of knowledge required for such activities, other difficulties also exist. The global industrial environment makes it challenging to identify sources of, and access to, knowledge. Typically, such sources (e.g., repositories) are made to search and retrieve information about software unitsand not about the required reuse activity knowledge for a special unit. Additionally, the knowledge has to be learned by inexperienced software engineers and, therefore, to be interpreted. This interpretation may lead to variations in the reuse result and can differ from the estimated result of the knowledge creator. This makes it difficult to exchange knowledge between software engineers or global teams. Additionally, the reuse results of reuse activities have to be repeatable and sustainable. In such a scenario, the knowledge about software reuse activities has to be exchanged without the above mentioned problems by an inexperienced software engineer. The literature shows a lack of techniques to store and subsequently distribute relevant reuse activity knowledge among software engineers. The central aim of this thesis is to enable inexperienced software engineers to use knowledge required to perform reuse activities without experiencing the aforementioned problems. The reuse activities: transformation, integration, and deployment, have been selected as the foundation for the research. Based on the construction level of handling a software unit, these activities are called Software Construction Activities (SCAcs) throughout the research. To achieve the aim, specialised software construction activity models have been created and combined with an abstract software unit model. As a result, different SCAc knowledge is described and combined with different software unit artefacts needed by the SCAcs. Additionally, the management (e.g., the execution of an SCAc) will be provided in a service-oriented environment. Because of the focus on reuse activities, an approach which avoids changing the knowledge level of software engineers and the abstraction view on software units and activities, the object of the investigation differs from other approaches which aim to solve the insufficient reuse activity knowledge problem. The research devised novel abstraction models to describe SCAcs as knowledge models related to the relevant information of software units. The models and the focused environment have been created using standard technologies. As a result, these were realised easily in a real world environment. Softwareengineers were able to perform single SCAcs without having previously acquired the necessary knowledge. The risk of failing reuse decreases because single activities can be performed. The analysis of the research results is based on a case study. An example of a reuse environmenthas been created and tested in a case study to prove the operational capability of the approach. The main result of the research is a proven concept enabling inexperienced software engineers to reuse software units by reusing SCAcs. The research shows the reduction in time for reuse and a decrease of learning effort is significant.

<p>Open source software is becoming a credible and realistic alternative to proprietary software in municipalities. The aim of this thesis is to explore the strategies and logical issues that inspire and motivate municipalities to migrate into or integrate use of open source software. The research approach used in the study is an explorative, comparative case study performed in the three Swedish municipalities of Falköping, Alingsås and Kungälv, which considers implementation and use of OpenOffice in administration. The methodologies used in the case study were in-depth interviews with Chief Information Officers in the municipalities and document analysis. The interviews were combined with the tool of SWOTanalysis to further focus on the reasons for choosing OpenOffice as an application program. There is certainly not a unique strategy to migrate into or integrate use of Free/Open Source Software. Since each municipality is autonomous in the process of decision-making, various strategic planning or guidelines are use in different municipalities. In the municipalities of Alingsås and Kungälv the strategic planning is used for leading the processes of implementation of new software applications. However, in Falköping municipality, the procedures are guided by a set of guidelines. The lower Total Cost of Ownership and the Free/Open Source Software’s freedoms besides many other advantages, make the municipalities stimulated to migrate into use of OpenOffice suite. In contrast, there are some drawbacks and barriers, such as shortage of internal and external standardization and lack of user knowledge and familiarity, which demotivate the municipalities to take this decision. To lower costs of IT administration seems to be the most significant factor in motivating municipalities to migrate into use of OpenOffice. More research is needed in order to find out the consequences of implementation of OpenOffice in municipalities as well as to investigate if Total Cost of Ownership really is decreased by the use of Open Office.</p>

Approved for public release; distribution is unlimited / Software is often developed under a process that can at best be described as ad hoc. While it is possible to develop quality software under an ad hoc process, formal processes can be developed to help increase the overall quality of the software under development. The application of these processes allows for an organization to mature. The software maturity level, and process improvement, of an organization can be measured with the Capability Maturity Model. The scope of this work is to use organizationally improved software processes on a small scale software product developed by the U.S. Army . The goal is to establish process improvement based on the Capability Maturity Model. / Civilian, United States Army TACOM
