Empirical investigation on adoption and adaptation of agile practices

Manyam, Venkata Sarath Chandra, Kurapati, Narendra January 2012 (has links)
Context: Agile practices have created its own mark on recent software development strategies. The significance of agile core values and principles attracted several organizations towards agile software development. Agile methods incorporate core values & principles, whereas agile practices define how agile methods are implemented in practice. However, it is still unclear, which combinations of agile practices are adopted in practice and how are they adapted. Objectives: In this research, our main aim is to find the combinations of agile practices that are most commonly adopted in practice, which includes identifying the practices which mostly appear together and finding the evidences for adaptations of agile practices. Methods: We have developed a survey to collect empirical evidence regarding agile practice adoption and adaptation. The survey is based on a framework consisting of a set of questions to determine agile practice adoption and adaptation. The framework was validated with researchers and practitioners through interviews. In order to identify the practices and possible adaptations we conducted a literature review. The sample population of the survey includes primarily project managers, developers, agile coaches and system types includes majority of information systems, commercial type of software, outsourced and embedded. Results: We have collected 109 responses with the survey. It is important to make the tradeoff between the length of the survey and quality of the responses, so, we needed to pose many questions with regard to the ways how the practices are tailored/adapted. We found that there are certain practices which were given highest priority and mostly appear together, certain practices appears only with particular combinations of practices. Regarding practice adaptations, the empirical findings show the adaptations of each individual practice. Moreover, regarding employee and customer satisfaction, the results indicate that there is a significant level of satisfied employees and customers with agile software development. A conceptual model of agile practices and performance is developed and presented to make a better understanding of implications for practice. Conclusions: During adoption there are certain set of agile practices that were given higher importance, given highest priority during selection and also mostly appears together. Moreover, there are certain practices which are considered as most important, but are given with less priority during selection by practitioners. Furthermore, the empirical findings supports practice adaption depends on change in context factors. Finally, it is interesting to see that almost all of the stakeholders in agile software development are satisfied with its nature.

Cultura organizacional e adoção de práticas ágeis : uma análise exploratória

Soares, Lourenço Piuma January 2011 (has links)
A adoção de metodologias ágeis tem se provado uma atividade sensível a cultura das organizações que as aplicam. Nos dez anos que se sucederam ao Agile Manifesto, projetos ágeis se desenvolveram a partir de tentativas conduzidas em situações ideais até grandes iniciativas adaptadas para as mais diversas condições. Por outro lado, a cultura organizacional tem se provado determinante na maneira que organizações abordam os desafios que se apresentam. Este trabalho tem por objetivo explorar a relação entre os pressupostos culturais básicos das organizações e práticas ágeis selecionadas. Para isso, se buscou identificar, através de revisão da literatura, pressupostos básicos significativos, práticas ágeis representativas e como se dá a interação entre esses, mapeando correlações através de uma survey. Essa se trata de um questionário respondido por funcionários da consultoria de TI ThoughtWorks a partir de sua experiência em projetos ágeis em clientes. A partir do resultado da survey foram exploradas as correlações identificadas – inclusive no que diz respeito à experiência e satisfação dos clientes com metodologias ágeis – e as observações foram validadas com consultores especialistas em métodos ágeis e em cultura organizacional. Procurou-se, assim, oferecer um mapa inicial para investigar a relação entre cultura organizacional e práticas ágeis que pode sugerir abordagens para introdução de práticas ágeis baseadas no perfil cultural da organização aonde se busca introduzi-las. / Companies adopting Agile methodologies have proven sensible to cultural differences. Ten years after the Agile Manifesto, agile projects have grown from small teams operating in specific situations to big cross-national initiatives. Organizational culture, in the other hand, is considered a determining factor in the way an organization perceives the world and interacts with it. In this paper, the relation between basic cultural assumptions of an organization will be matched up against a few selected agile practices. To achieve that, it looked into the literature to map these basic assumptions and representative agile practices, aiming to establish correlations between them through the results of a survey. This survey is a questionnaire answered by employees of the IT consultancy firm ThoughtWorks based on their experience in agile projects in client‟s organizations. Based on the survey results, some correlations were identified and analysed – including some regarding client experience and satisfaction with agile – and the observations were submitted to consultants, specialist in both agile practices and organizational culture for confirmation of the findings. It aimed to offer an initial map to investigate relations between organizational culture and agile practices looking to suggest new approaches for the introduction of agile practices based on the cultural profile of the target organization.

Investigating the Applicability of Agile Practices in Software Organizations / Undersöka tillämplighet Agile Practices i programvaru Organisationer

Madhira, Phani Srikara Sastry January 2015 (has links)
Agile software development has gained significant importance the recent years. Software practitioners have recognized the importance of agile development due to the benefits offered. Therefore, agile software development has been identified as the replacement to traditional or plan driven style of development. There are different frameworks or methods, which follow agile principles, known as agile methodologies. SCRUM and XP are the most popular and widely used agile methods or framework. There are different types of agile methodologies, each containing a set of practices, which can be adapted and implemented in an organization. However, there is still a need for empirical studies to understand the factors like requirements/modifications, challenges and mitigation strategies/techniques, which can enable successful implementation of agile practices in software organizations. In this study, the primary objective is to provide a comprehensive model or framework to practitioners, which includes the list of important requirements/modifications, challenges and mitigation strategies/techniques while implementing agile, and also pertaining to adoption/implementation of individual agile practices specific to SCRUM and XP. This model also includes the categorization of the requirements/modifications and challenges into different levels of an organization, to which they mostly apply. This conceptual model or framework can aid the practitioners in understanding and implementing agile practices in a better way in their organizations. In this study, an industrial survey is conducted in order to identify the list of important requirements/modifications that are needed to implement agile, challenges faced during implementation, and mitigation strategies/techniques needed to address the challenges. Also, categorization of the identified lists into different levels of the organization is also performed using survey. A systematic literature review is performed in order to identify the primary lists of requirements/modifications, challenges and mitigation strategies/techniques, which are further validated and classified using survey. Also, systematic literature review is used to identify the list of requirements/modifications, challenges and mitigation strategies/techniques that are needed while implementing individual agile practices specific to SCRUM and XP. Based on the systematic literature review, 53 primary studies were identified which are relevant to the research area. Upon analyzing the primary studies, the list of requirements/modifications, challenges and solutions are identified for generic agile adoption/implementation and also pertaining to individual practices specific to SCRUM and XP. Thereupon, an industrial survey is conducted where, identified list of requirements/modifications, challenges and mitigation strategies/techniques are provided to the respondents. Respondents were asked to classify the obtained aspects based on the level of importance. Also, they were asked to categorize the obtained requirements/modifications and challenges into different levels of an organization. The survey has obtained 48 responses from different parts of the world. From the results of survey, requirements/modifications, challenges and mitigation strategies/techniques are classified based on the level of importance. Also, requirements/modifications and challenges are categorized into different levels of an organization. Using the obtained factors, a conceptual model or framework was constructed for practitioners that can enable them to understand and implement agile practices in their organizations in a better way. To conclude this research, a comprehensive model or framework was constructed using the final list of important requirements/modifications, challenges and mitigation strategies/techniques while implementing/adopting agile and also pertaining to the individual agile practices, and also based on the categorization of the requirements and challenges into levels of an organization, where they are applicable. The final list of identified lists of requirements/modifications; challenges and mitigation strategies/techniques pertaining to individual agile practices can help practitioners to understand the implementation criteria of agile practices in software organizations. It was observed from the results of survey that perception of literature and practitioners are different in terms of usage of agile practices, as some practices, which were given high focus in the literature, were not given equal priority by the respondents. Empirical findings also help to identify change in policies and procedures and change to open workspace as most important requirements/modifications, organizational resistance and lack of motivated programmers as most critical challenges and proper training and inclusion of experts as most used mitigation strategies/techniques. Moreover, it was concluded that there is also a need for further full-scale empirical works on identifying the factors that affect adoption of agile. Practitioners can identify the benefits from this research and researchers can extend this work to remaining agile methodologies. / Agile systemutveckling har fått stor betydelse de senaste åren. Programvaru utövare har insett vikten av agila utvecklings grund av de förmåner som erbjuds. Därför har agile mjukvaruutveckling identifierats som ersättare till traditionella eller planen driven stil av utveckling. Det finns olika ramar eller metoder, som följer agila principer, så kallade agila metoder. SCRUM och XP är de mest populära och mest använda agila metoder eller ramverk. Det finns olika typer av agila metoder, var och en innehåller en uppsättning metoder, som kan anpassas och genomföras i en organisation. Det finns dock fortfarande ett behov av empiriska studier för att förstå de faktorer som krav / modifieringar, utmaningar och begränsningsstrategier / tekniker, som kan göra det möjligt för ett framgångsrikt genomförande av agila metoder i mjukvaruorganisationer.  I denna studie, är det primära målet att ge en heltäckande modell eller ramverk för utövare, vilket inkluderar en lista över viktiga krav / modifieringar, utmaningar och begränsningsstrategier / tekniker samtidigt genomföra vig, och även avseende antagande / genomförande av enskilda agila metoder specifika SCRUM och XP. Denna modell innehåller även kategoriseringen av de krav / modifieringar och utmaningar i olika nivåer i en organisation, till vilken de oftast gäller. Denna konceptuella modell eller ramverk kan hjälpa utövarna att förstå och genomföra agila metoder på ett bättre sätt i sina organisationer. I denna studie är en industriell undersökning för att identifiera listan över viktiga krav / ändringar som behövs för att genomföra vig, utmaningar under genomförandet, och begränsnings strategier / tekniker som behövs för att ta itu med utmaningarna. Också, kategorisering av de identifierade listorna i olika nivåer i organisationen är också utföras med undersökningen. En systematisk litteraturöversikt görs för att identifiera de primära listor krav / modifieringar, utmaningar och begränsningsstrategier / tekniker, som är validerade längre och klassificerade med hjälp enkät. Dessutom är systematisk litteraturöversikt används för att identifiera en lista över krav / modifieringar, utmaningar och begränsningsstrategier / tekniker som behövs samtidigt genomföra enskilda agila metoder som är specifika för SCRUM och XP. / +918500053444
