Application of Agile Methods in Distributed Software Development

Kuziwa, Ally, Ndagire, Kazibwe Flavia January 2016 (has links)
Agile software development methods are characterized by developer’s empowerment through self-organization, incremental requirements and constant knowledge sharing. Despite some effort to elaborate how successfully agile methods can be applied in co-located development teams, little is known on how the same is done when the development teams are distributed. Our research focus is to uncover factors that influence the successful application of agile methods in distributed development teams using a software development company as our case study. With three distributed teams applying different agile methods, we conducted focused ethnography alongside interviews to comprehend what and how various factors under distributed development teams influence successful agile methods application. It seems, all that matters is team structure, team spirit, effective communication, product requirements, and knowledge sharing. The team structure has more influence than other factors and therefore our suggestions for successful application of agile methods in distributed software development is to focus on the development team, above all factors. The analysis shows that the development methods themselves have little to do with the successful application of agile methods in distributed software development teams.

Implementation and Certification of ISO/IEC 29110 in an IT Startup in Peru

García Paucar, Luis Hernán, Laporte, Claude Y, Arteaga, Yaylli, Bruggmann, Marco 18 March 2015 (has links)
This article presents the implementation of ISO/IEC 29110 in a four-person IT startup company in Peru. After completing the implementation of the ISO/IEC 29110 project management and software implementation processes using an agile approach, the next step was to execute these processes in a project with an actual customer: software that facilitates communication between clients and legal consultants at the second-largest insurance companies in Peru. Managing the project and developing the software took about 900 hours. Using ISO/ IEC 29110 software engineering practices enabled the startup to plan and execute the project while expending only 18 percent of the total project effort on rework (i.e., wasted effort). In this article, the authors also describe the steps and the effort required by the VSE to be granted an ISO/IEC 29110 certificate of conformity. The startup became the first Peruvian VSE to obtain an ISO/IEC 29110 certification. The ISO/IEC 29110 certification facilitated access to new clients and larger projects.

TOWARDS A REFLECTIVE-AGILE LEARNING MODEL AND METHOD IN THE CASE OF SMALL-SHOP SOFTWARE DEVELOPMENT: EVIDENCE FROM AN ACTION RESEARCH STUDY

Babb, Jeffry 13 April 2009 (has links)
The ascension and use of agile and lightweight software development methods have challenged extant software design and development paradigms; this is especially notable in the case of small-team and small-shop software development. In this dissertation, a Reflective-Agile Learning Method and Methodology (RALMM) for small-shop software development, is proposed to enhance communication and learning in the use of agile methods. The purpose of the inquiry in this dissertation pertains to: the nature of the professional practice of small team software development; the implications of the epistemology of Reflective Practice has for the professional practice of small-team software development; and whether the introduction of Reflective Practice to an extant agile methodology improves process, productivity and professional confidence for a small development team. This dissertation uses Dialogical Action Research (Mårtensson and Lee 2004), or Dialogical AR, a qualitative and interpretive research approach, to iteratively develop and refine the Reflective-Agile Learning Model and Method (RALMM). The proposed model and method also considers Hazzan and Tomayko’s (2002, 2004, and 2005) synthesis of Schön’s (1983, 1987) Reflective Practice and Extreme Programming (XP). RALMM is shaped by Argyris and Schön’s theories of practice (1974) and Organizational Learning (1978, 1996) and Schön’s ancillary work on generative metaphor (1979) and frames (Schön et al. 1994). The RALMM artifact was developed in a Dialogical AR Partnership using Lee’s (2007) framework for synthesizing design science and action research. The development and use of RALMM facilitated theorizing on the role of Reflective Practice in the successful use of agile methods. To assist in interpretation and analysis, the data collected during Dialogical AR cycles are analyzed using Strauss and Corbin’s (1998) Grounded Theory as a mode of analysis to guide in the coding and analysis of qualitative evidence from the research. As a result of this research, RALMM improved the practitioners’ processes and productivity. Furthermore, RALMM helped to establish, formalize and reinforce a team learning system for the continued development of the practitioners’ professional repertoire. Additionally, the iterative development of RALMM provides a basis for theorizing on Reflective Practice as an epistemology, paradigm, metaphor and frame of reference for the professional practice of small-shop software development.

Métricas de avaliação para abordagens ágeis em projetos de software

Pegoraro, Raquel Aparecida January 2014 (has links)
A adoção de métodos ágeis é uma forma eficaz de reduzir o ciclo de entrega no desenvolvimento de software, fornecendo software de qualidade em curto espaço de tempo. Porém, a adoção desta nova abordagem de desenvolvimento de software torna necessário repensar a forma de medir e controlar os projetos. Os métodos ágeis não tratam claramente sobre os assuntos utilização de métricas e adoção de um processo de medição para projetos de softwares desta natureza, faltando estudos que tragam recomendações em como estabelecer métricas para projetos ágeis e como adotar um processo de medição compatível com esta abordagem. Visando contribuir neste sentido esta tese tem como objetivo definir um conjunto de métricas adequadas às necessidades de monitoramento e propor um processo de medição, compatível com a abordagem ágil de desenvolvimento de software. Como método de pesquisa foi realizado um trabalho exploratório através de revisão de literatura e de pesquisa de campo com entrevista em profundidade em empresas de desenvolvimento de software experientes em métodos ágeis. O primeiro resultado do trabalho é a apresentação de um conjunto de métricas consolidados para auxiliar na gestão de projetos ágeis de desenvolvimento de software nas fases de projeto/releases, iteração e diário. As métricas são especificadas detalhadamente contendo as informações necessárias para seu entendimento e aplicação. Posteriormente é proposto um processo de medição compatível com a abordagem ágil de desenvolvimento de software, visando apoiar as empresas que adotam métodos ágeis na definição de métricas adequadas para suas necessidades de medição e no monitoramento. O processo contempla as fases de planejamento de medição, monitoramento da iteração, ações da iteração, monitoramento do projeto/releases, ações sobre o projeto/releases e avaliação final, sendo que em cada fase do processo são apresentadas recomendações para a sua implantação. O processo está estruturado num ciclo de gestão baseado em etapas de planejar, executar, verificar, atuar, refletir e melhorar, respeitando as características dos projetos ágeis de desenvolvimento de software, e na proposição de um quadro visual de monitoramento que permita a gestão do processo de medição de forma visual. Além dos resultados apresentados foram deixadas hipoteses e recomendações para trabalhos futuros. / The adoption of agile methods is effective way to reduce the delivery cycle on software development, providing quality software in a short time.

Agile methods not explain about adoption metrics and measurement process for software projects of this approach, lacking studies providing recommendations on how to establish metrics for agile projects and how to adopt a process measurement compatible with this approach. Contributing this thesis goal produce a set of metrics adequate monitoring needs and propose a measurement processcompatible with agile software development. Method of research was exploratory through literature review and field research with depth interviews in experienced software development companies in agile methods. The first result of this work is the presentation of a consolidated metrics set to help the management of agile development at the phases of project/releases, iteration and daily. The metrics are specified detailed containing the information necessary for their understanding and application. Later we propose a measurement process compatible with agile approach to software development, to support businesses that adopt agile methods in defining adequate metrics for your measurement needs and monitoring. The process include the steps of measurement planning, monitoring of the iteration, the iteration actions, monitoring project/releases, actions on the project/releases and final evaluation, in each stage of the process provides recommendations for implementation. The process is structured in a management cycle based on steps to plan, implement, check, act, reflect and improve, respecting the characteristics of agile software development projects and propose a visual tracking board that allows for the management of the measurement process. In addition to the results were allowed hypotheses and recommendations for future work.

Sendo assim, esta pesquisa visa investigar de que forma os fatores humanos influenciam no processo de desenvolvimento ágil de software, para aumentar as chances de sucesso desses projetos. Para isto, foi conduzida uma revisão sistemática da literatura (RSL) e um survey para atingir esse objetivo. Foram encontrados 12 (doze) fatores humanos como: comunicação, aspectos culturais, liderança, motivação, bem-estar, autonomia, conhecimento, experiência, aprendizado, colaboração, confiança e envolvimento do cliente. Tais fatores impactam, positivamente e/ou negativamente, nas seguintes áreas: desenvolvimento de software, interação do time, sucesso de projetos ágeis e tomada de decisão. Por fim, tanto a RSL quanto o survey permitem confirmar que os fatores humanos mais relevantes dentro de métodos ágeis são Comunicação e Colaboração, o que se relacionam com características relacionadas a “indivíduos e interações entre os membros da equipe” descritas no Manifesto ágil. / The publication of the Agile Manifesto shows a large amount of human interaction in the software development process, as can be seen in some of their assumptions, such as: "Individuals and their interactions", "Customer collaboration," showing that these methods concern themselves with the human factors involved in the software development processes. Thus, this research intends to investigate how human factors influence the agile development process software, to increase the chances of success of these projects. For that, it was conducted a systematic literature review (SLR) and a survey to achieve this goal. It was found 12 human factors, such as: communication, cultural, leadership, motivation, well-being, autonomy, knowledge, experience, learning, collaboration, trust and customer engagement. Such factors impact positively and / or negatively, in the following areas: software development, team interaction, successful agile projects and decision making. Finally, both the RSL and the survey support the assertion that the most relevant human factors within agile methods are Communication and Collaboration, which relate to characteristics related to "individuals and interactions between team members" described in the Agile Manifesto.

In this context, the use of Virtual Learning Environments - software designed to support the courses via the Internet - is growing and access becoming increasingly diverse, ranging from desktop computers to mobile smartphones. Thus, the complexity of creating these environments becomes increasingly technical and requires Software Engineering and Project Management always better to ensure product quality and customer satisfaction generated. Given such a scenario, this paper proposes the use of Agile methodologies in the development and project management of virtual environments as a more interesting way than traditional software delivery based only on product quality, forgetting often , customer satisfaction and motivation of developers. This paper reports the adoption of agile methodologies in the development of the SOLAR AVA 2.0, showing that it is possible to succeed in both the technical level and at the organizational and personally with the adoption of agile practices in the development of AVAs that can be proven through experiments done with the satisfaction surveys with users and project developers. / Nas duas últimas décadas houve um considerável avanço no uso de Tecnologias da Informação e Comunicação Digitais no processo de ensino e aprendizagem, tanto na modalidade de Educação presencial quanto a distância. Neste contexto, o uso de Ambientes Virtuais de Aprendizagem - softwares criados para o suporte a cursos através da Internet - vêm crescendo e seu acesso se tornando cada vez mais diversificado, indo de computadores desktop a celulares smartphones. Desta forma, a complexidade de criação destes ambientes se torna cada vez maior e exige técnicas de Engenharia de Software e Gestão de Projetos cada vez melhores para garantir a qualidade do produto gerado e a satisfação do cliente. Tendo em vista tal cenário, o presente trabalho propõe o uso de Metodologias Ágeis tanto no desenvolvimento quanto na gestão de projetos de ambientes virtuais como uma solução mais interessante que a tradicional forma de criação de softwares baseada somente na qualidade do produto, esquecendo, muitas vezes, a satisfação do cliente e a motivação dos desenvolvedores.

A Study of Creativity and Innovation within Agile Project Management : A Quasi-experimental Case Study of a Scrum Team

Sjölund, Erik January 2018 (has links)
This master thesis has been conducted at Uppsala University and was performed in collaboration with the company Alten Sverige AB during a time period of twenty weeks.The purpose of the study was to enhance the creative and innovational output of agile project teams within the organization by revising and improving an existing management system. The thesis was divided into two main phases. The first phase had a theoretical focus and included a literature study with the objective to create a knowledge baseline from academia, compare it with the existing system, and to revise and improve the management system. The second phase had an empirical and consisted of a quasi-experimental case study of a scrum team and implementation of the management system with the objective to get information of how the studied team perceived the improved system.The literature study looked into three main topics; creativity, innovation, and agility. The topics was studied to see the connections between them and to find common barriers and enablers for creative and innovational output. The case study observed and interacted with the scrum team to gather information about their current work process. Their work process later altered during the quasi-experimental implementation stage based on the new requirements within the updated management system. To see if the team’s perception of the work process had changed a questionnaire was answered before and after the work process was altered. The questionnaire was answered by the studied team and a reference group to increase the studies validity.The results from the literature study showed that there were several characteristics of creativity, innovation and agility that was considered to be either enablers or barriers and a few characteristics which saw contradictions in the literature. The findings from the study was compared, analyzed and mapped out into topics, sub-topics, and requirements within the management system, which was simultaneously updated. The results from the implementation stage and the documentation of the team’s changed perceptions showed that eleven characteristics identified as enabler was strengthened by the empirical findings, one enabler was weakened (deadlines), and one new enabler emerged (direct contact with external expertise or customer). Regarding the barriers, four of them was strengthened, one was weakened (diversity), and one new barrier was discovered (insufficient documentation).

Projeto evolutivo de bases de dados : uma abordagem iterativa e incremental usando modularização de bases de dados / Evolutionary database design : an iterative and incremental approach using database modularization

Guedes, Gustavo Bartz, 1983- 02 November 2014 (has links)

No. of bitstreams: 1 Guedes_GustavoBartz_M.pdf: 5989312 bytes, checksum: 0e3053f8f1adcbcf13039b8caeb8a87e (MD5) Previous issue date: 2014 / Resumo: Sistemas de software evoluem ao longo do tempo devido a novos requisitos ou a alterações nos já existentes. As mudanças são ainda mais presentes nos métodos de desenvolvimento de software iterativos e incrementais, como os métodos ágeis, que pressupõem a entrega contínua de módulos operacionais de software. Os métodos ágeis, como o Scrum e a Programação Extrema, são baseados em aspectos gerenciais do projeto e em técnicas de codificação do sistema. Entretanto, mudanças nos requisitos provavelmente terão reflexo no esquema da base de dados, que deverá ser alterado para suportá-los. Quando o sistema se encontra em produção, alterações no esquema da base de dados são onerosas, pois é necessário manter a semântica dos dados em relação à aplicação. Portanto, este trabalho de mestrado apresenta o processo evolutivo de modularização de bases de dados, uma abordagem para projetar a base de dados de modo iterativo e incremental. A modularização é executada no projeto conceitual e amplia a capacidade de abstração do esquema de dados gerado facilitando as evoluções futuras. Por fim, foi desenvolvida uma ferramenta que automatiza o processo evolutivo de modularização de bases de dados, chamada de Evolutio DB Designer. Essa ferramenta permite modularizar o esquema da base de dados e gerar automaticamente o esquema relacional a partir dos módulos de bases de dados / Abstract: Software systems evolve through time due to new requirements or changing in the existing ones. The need for constant changes is even more present on the iterative and incremental software development methods, such as those based on the agile methodology, that demand continuous delivery of operational software modules. The agile development methods, like Scrum and Extreme Programming, are based on management aspects of the project and techniques for software coding. However, changes in the requirements will probably affect the database schema, which will have to be modified to accommodate them. In a production system, changes to the database schema are costly, because from the application¿s perspective the data semantics needs to be maintained. Therefore, the present work presents the evolutionary database modularization design process, an approach for the iterative and incremental design of the database. The modularization process is executed during the conceptual design improving the abstraction capacity of the generated data schema resulting in a graceful schema evolution. In addition, a tool that automates the evolutionary database modularization design process was developed, called Evolutio DB Designer. It allows the modular design of the database schema and automatically generates the relational data schema based on the database modules / Mestrado / Tecnologia e Inovação / Mestre em Tecnologia
