Aseguramiento de la calidad de un recurso organizacional: evaluando y mejorando una estrategia integrada de medición y evaluación

Esta tesis presenta el trabajo de investigación cuyo objetivo final fue mejorar la Estrategia Integrada de Medición y Evaluación GOCAME (Goal-Oriented Context-Aware Measurement and Evaluation). La premisa que guió la investigación fue que una estrategia de Medición y Evaluación (M&E) es integrada si posee simultáneamente las siguientes tres capacidades: (1) un marco conceptual con una base conceptual estructurada de M&E; (2) la especificación del proceso; y (3) la especificación de métodos. Bajo esta premisa se realizó un caso de estudio donde dos estrategias integradas fueron evaluadas, a saber: GOCAME y GQM+Strategies (Goal-Question-Metric Plus Strategies), considerando como foco la Calidad de las Capacidades para la categoría de ente «Recurso». Del análisis de los resultados se obtuvo una lista de debilidades y fortalezas de las estrategias evaluadas, con la cual se elaboró un conjunto de recomendaciones de cambio. Luego, se planificaron las acciones de mejora para GOCAME y se efectuaron los cambios -especialmente de aquellos atributos más débiles. Una vez realizadas las mejoras planificadas, se llevó a cabo la reevaluación de GOCAME. A partir de aquí, se efectuó una comparación entre ambas evaluaciones –antes y después de los cambios en GOCAME- lo que brindó evidencia cuantitativa acerca del nivel de impacto de las mejoras incorporadas. En líneas generales, las etapas realizadas en esta investigación fueron: 1) el diseño y ejecución de un estudio comparativo para evaluar estrategias integradas de M&E con el objetivo de comprender y comparar el estado actual de las mismas; 2) la planificación y ejecución de acciones de mejora sobre la estrategia integrada de M&E denominada GOCAME; 3) el análisis de la ganancia de la mejora obtenida luego de los cambios realizados.Facultad de Informátic

Aseguramiento de calidad de software: estudio comparativo de estrategias de medición y evaluación

Este trabajo especifica e implementa un estudio comparativo para comprender y comparar estrategias integradas de medición y evaluación, considerando a una estrategia como a un recurso de un proyecto, desde el punto de vista del ente a valorar. El objetivo del estudio comparativo es evaluar la calidad de las capacidades de una estrategia de medición y evaluación teniendo en cuenta tres fundamentos: 1) el marco conceptual centrado en una base terminológica, 2) el soporte explícito de proceso, y 3) el soporte metodológico/tecnológico. A su vez, para diseñar el estudio tuvimos en cuenta para una estrategia aspectos de requerimientos no funcionales, de medición, de evaluación, y de análisis y recomendación. Como resultado de esta investigación hemos especificado el diseño del estudio; esto es, el árbol de requerimientos en función de características y atributos, el diseño de las métricas que cuantifican a estos atributos y su interpretación por medio del diseño de indicadores. Por otro lado, el resultado del estudio comparativo nos permitió un análisis de debilidades y fortalezas de las estrategias GQM+Strategies (Goal-Question-Metric Plus Strategies) y GOCAME (Goal-Oriented Context-Aware Measurement and Evaluation), con el fin de definir cursos de acción para mejorar nuestra estrategia, a saber: GOCAME.Facultad de Informátic

A Holistic Quality Evaluation, Selection and Improvement Approach driven by Multilevel Goals and Strategies

Organizations should establish business goals and check for their achievement in a systematic and disciplined way. In order to know if a business goal is achieved, it should be necessary to consider information need goals that also can require satisfying measurement and evaluation goals at operational level. Furthermore, if measurement and evaluation goals are not aligned with top-level business goals such as tactical or strategic level goals, the organization could waste its effort and resources. Usually, the different goals established in an organization are operationalized through projects. For a given project, strategies should be used in order to help in the goal achievement. A strategy defines a set of activities and methods to be followed for a specific goal purpose. Ultimately, to engineering all these issues in a systematic way, organizations should adopt a holistic evaluation approach supported by a set of integrated strategies. By means of a systematic literature review as research method, we have observed that very few approaches support integrated strategies and multilevel goals. To bridge this gap, we have developed a holistic quality multilevel and multipurpose evaluation approach that ties together multilevel goals, projects and integrated strategies. As contributions, this paper discusses an enhanced conceptual base (specified by ontologies) for linking business and information need goal concepts with project, strategy and nonfunctional requirements concepts. Then, it defines the step by step of our holistic quality evaluation approach, by listing the necessary activities to establish goals and projects at different organizational levels. Lastly, it specifies and illustrates evaluation scenarios for business/information need goal purposes such as understanding, improving, monitoring and controlling, comparing and selecting entities, which are supported by strategies and strategy patterns.Fil: Rivera, María Belén.

Evaluation and Improvement of an Organizational Resource applying Strategy Patterns

For any software company that frequently performs quality assurance activities devoted to measurement, evaluation (ME) and change/improvement (MEC) projects, ME and MEC strategies can be valuable organizational assets. In this paper, we analyze the improvement of a ME strategy, which can be considered an organizational resource to be applied to quality assurance activities. This resource is called the GOCAME (Goal-Oriented Context-Aware Measurement and Evaluation) strategy. AME/MEC strategy embraces the next three integrated capabilities: 1) the ME/MEC domain conceptual base and framework; 2) the process perspective specifications; and, 3) the method specifications. The improvement of GOCAME was performed instantiating two strategy patterns. A strategy pattern is a reusable solution to recurrent problems in ME/MEC projects. For an improvement goal, the selected MEC strategy pattern allows instantiating in a project a set of tailored activities and methods for measurement, evaluation, analysis and change. Particularly, we instantiate the GoME_1QV (Goal-oriented Measurement and Evaluation for One Quality View) strategy pattern to understand the GOCAME current quality state and compare it with the so-called GQM+ Strategies. First, this evaluation and analysis allows us to know the GOCAME strengths and weaknesses with regard to the quality of the three capabilities. Second, we instantiate the GoMEC_1QV (Goal-oriented Measurement, Evaluation and Change for One Quality View) strategy pattern to improve the GOCAME current state, producing as result a new version of the GOCAME strategy.Fil: Papa, María Fernanda.

Family of Evaluation Strategies: A Practical Case for Comparing and Adopting Strengths

Companies commonly establish and pursue business goals. A goal states a purpose. In the Software Engineering literature, different evaluation purposes such as to understand, monitor, improve, control, compare and select are mentioned. Considering that these purposes share distinctive and common aspects, in the present work, we include a categorization that helps a better understanding of them. On the other hand, to reach the purpose of a goal, a suitable strategy should be chosen. A strategy describes a particular course of action by means of process and method specifications. We have envisioned different strategies for different evaluation goal purposes. Therefore, in this paper we also present some strategies, which are part of a family of strategies driven by measurement and evaluation activities. Specifically, we document evaluation strategies for the monitoring, improving, and comparing and adopting purposes. In addition, we illustrate the comparing and adopting strategy applied to four social network mobile apps.Facultad de Informátic

A extinção do princípio trabalhista da contribuição sindical obrigatória?

O Direito do Trabalho pode ser identificado pela existência de objeto, institutos, teorias e, especialmente, princípios próprios, que são responsáveis por estabelecer o seu arcabouço, a base de sustentação que o define. Insta salientar que vários juristas publicaram trabalhos sobre princípios trabalhistas, mas verificamos, especialmente na obra da autora Vólia Bomfim Cassar, intitulada ‘Princípios trabalhistas, novas profissões, globalização da economia e flexibilização das normas trabalhistas’, o princípio da contribuição sindical obrigatória. Este sucinto estudo, utilizando a metodologia de pesquisa bibliográfica, propõe investigar se o princípio trabalhista da contribuição sindical obrigatória se mantém no ordenamento jurídico após a edição da lei 13.467/17, chamada reforma trabalhista, que alterou dispositivos da Consolidação das Leis do Trabalho – CLT e outros diplomas legais

Association between self-control and health risk behaviors: a cross-sectional study with 9th grade adolescents in São Paulo.

BACKGROUND: Self-control (SC) has been consistently found associated with diverse health risk behaviors (HRBs), but little research refers to low- and middle-income countries. Furthermore, there is evidence that some HRBs tend to aggregate, however studies with the specific purpose of addressing the relation between SC and multiple health risk behaviors (MHRBs) are rare. The objective of this study is to analyze these associations and provide evidence to help filling these gaps. METHODS: A sample of 2106 9th grade students from the city of São Paulo responded a self-administered questionnaire in 2017. We tested the association of SC measured as an ordinal variable with four levels (higher, high, medium and low) with six HRBs (binge drinking, marijuana use, smoking, high consumption of ultra-processed food, sedentary behavior and bullying perpetration), in both separated and aggregated forms (MHRBs), controlling for potential confounders. Binary logistic regression was used to test the association between exposure (SC) and single outcomes. In order to analyze the association of SC with MHRBs, multinomial logistic regression was employed. RESULTS: SC was associated with five of six HRBs investigated and with MHRBs. The effect size of the association of SC and MHRBs increased in a steep pattern with accumulation of more HRBs. CONCLUSION: Low self-control is associated with most HRBs investigated and the magnitude of the association increases when more than two or three HRBs are accumulated. There seems to be a group of adolescents in a position of pronounced vulnerability for MHRBs. This should be considered when designing public policy and prevention programs. In contexts of limited or scarce resources and public funds, interventions focusing the most vulnerable groups, instead of universal interventions, should be considered
