Porém, envolve também a comunidade no entorno da escola, a família, professores e todos aqueles que atuam no processo educacional desses sujeitos. O fenômeno não possui compreensão consensual e desde a década de 1950 tem sido alvo de estudos de diferentes áreas do conhecimento em todo o mundo. Esses seguimentos tentam buscar um consenso acerca do entendimento das formas de manifestação da violência na escola, bem como no que se refere à tentativa de combate-la com vistas a reduzir os impactos desencadeados no curso de vida dos envolvividos. Com base em tais considerações, a presente pesquisa teve por escopo realizar uma revisão de literatura sobre a violência escolar e a respeito das formas pelas quais ela tem sido rastreada no contexto educacional, sobretudo no perído compreendido entre os anos de 2000 à 2015. A delimitação desse período se justifica tendo em vista a divulgação do primeiro levantamento sobre o tema feito no Brasil a partir de meados da década de 1980 seguindo uma tendência mundial; assim como pela necessidade de conceber as maneiras pelas quais o fenômeno continuou a ser investigado e abordado nacional e internacionalmente. A busca dos textos para a revisão ocorreu a partir da eleição das bases de dados mais apropriadas, isto é, com escopo de catalogação de textos sobre o tema em pesquisa, para o levantamento da literatura pertinente. Esse procedimento foi adotado a partir da identificação das bases junto ao site do banco de periódicos capes. As bases assim eleitas foram: Web of Science, Dialnet, Redalyc, Lilacs, Eric, GoogleSchoolar, Jstor e PsyvInfo. Nestas, após consulta ao dicionário de descritores, foram associandos os termos school violence or bullying à questionnaire; scale; instrument; assessment e measure. Objetivou-se, pois, levantar as definições de violência escolar salientadas nas publicações e verificar a ocorrência e uso de instrumentos de rastreio de violência escolar. Foram incluídos na presente revisão artigos científicos que abordassem o tema sem quaisquer associações a outras temáticas tais como problemas de saúde, de desenvolvimento, psiquiátricos ou jurídicos. As publicações indexadas em mais de uma base de dados e/ou referentes a monografias, dissertações, teses e capítulos de livros não foram incluídos no estudo. Para análise dos textos foram empregadas, respectivamente, as técnicas do estudo bibliométrico e da análise do conteúdo. A primeira visa oferecer um panorama da quantidade de publicações no período, por base de dados e autores, de metodologias utilizadas, seguimentos do conhecimento, localidade e periódicos das publicações decorrentes das pesquisas as originaram. A análise de conteúdo foi empregada com intuito de avaliar e compreender as maneiras pelas quais o fenômeno da violência escolar tem sido estudado e concebido, além de buscar compreensão das estratégias sobre o tema adotadas por pesquisadores, na tentativa traçar subsídios mais sistematizados para abordagens nas situações de violência. O levantamento nas bases de dados permitiu identificar 4278 publicações catalogadas. Com a aplicação dos critérios de exclusão, 268 artigos foram elencados para a leitura inicial dos resumos. Essa leitura permitiu identificar 119 (55,6%) publicações com relato de uso de instrumentos de rastreio da violência escolar. As demais (44,4%), consistiram em revisões de literatura e pesquisas qualitativas cujas técnicas envolveram entrevistas abertas, estudos de caso e/ou grupos focais. Dentre os demais resultados, a Redalyc indexou 27,1%(76) das publicações; e Pereira e Fonseca & Veiga representaram 2,33% do total de autorias. O Journal of School Violence e Archives of Scientific Psychology publicaram 12%(32) dos artigos. A classificação tipológica de pesquisa mencionada com maior frequência nas publicações foi a dos estudos transversais, com 35,8%(96). Os instrumentos de rastreio mais citados foram o Questionário de Bullying de Olweus e SVS- School Vitimization Scale, ambos representando 35,5%(50) dos textos estudados. A análise de conteúdo permitiu classificar três grandes categorias de avaliação das publicações: (A) definição de violência escolar; (B) tipos de atos agressivos e violentos perpetrados e sofridos; e (C) características psicométricas dos instrumentos de rastreio da violência escolar. Na categoria A constatou-se que uma tendência predominante em definir e compreender o fenômeno como sinônimo de bullying (53%); na categoria B, verificou-se que os sujeitos do sexo masculinos tendem a ser mais perpetradores do que vítimas dos atos agressivos e violentos, os quais são diversos, podendo ser tanto físicos, quanto morais e psicológicos ou virtuais. A categoria C possibilitou verificar, de modo geral, que os instrumentos predominantemente utilizados são adaptações de instrumento originalmente construídos no idioma inglês, o que evidencia limitações relativas a organização semâtica dos itens e, portanto, podendo comprometer a validade de construto. Os achados desta revisão de literatura indicam a importância da temática e a necessidade da continuidade dos estudos, principalmente que sejam condizentes com o contexto sociocultural do Brasil. / The school violence is a form of interpersonal violence mainly against children and adolescents in physical, sexual, moral, psychological, institutional and virtual forms. But it also involves the community around the school, family, teachers and all those working in the educational process. The phenomenon has no common understanding and since 1950 has been the subject of studies in different fields of knowledge worldwide. These threads try to seek a consensus in understanding the manifestation of these forms of violence in schools, as well as with regard to the attempt to reduce the effects triggered in the lives of those involved. Based on these considerations, the present study aimed to carry out a review of the literature on school violence and on instruments for which was screened in the educational context, especially in the period prescribed in the years 2000 to 2015. The demarcation that period is justified by taking as reference the first research on the subject made in Brazil since the mid 1980s; and the need to find ways in which the phenomenon continued to be investigated and treated in the country. The search for text revision occurred after the election of the most appropriate databases, ie, the collection of relevant texts to the topic under study. This procedure was adopted from the identification of the bases with the website of the Capes Periodicals. The so elected bases were: Web of Science, Dialnet, Redalyc, Lilacs, Eric, GoogleSchoolar, Jstor and PsycInfo. These, after consulting dictionaries descriptors were associated with the terms of school violence or intimidation to the questionnaire; scale; instrument; evaluation and measurement. The goal, therefore, was enumerating the definitions of school violence highlighted in publications and verify the occurrence and use of bullying screening tools and school violence. Were included in this review scientific articles that addressed the issue without any associations to other issues like health problems, developmental, psychiatric or legal. Publications indexed in more than one database and / or relating to monographs, dissertations, thesis and book chapters were not included in the study. For analysis of the texts were used, respectively, the bibliometric study and analysis of the content techniques. The first aims to provide an overview of the number of publications in the period, based on data and authors, used methodologies, knowledge area, site of the search the journal in which the articles were published. The content analysis was used to assess and understand the study of ways and approach to school violence phenomenon; and seek understanding of the strategies adopted by researchers on the subject, in an attempt to define more systematic approaches to subsidies in situations of violence. The search in the databases identified 4278 cataloged publications. With the application of the exclusion criteria, 268 articles were listed for the initial reading summaries. This reading has identified 119 (55.6%) publications use of screening tools reported school violence. The rest (44.4%) consisted of literature reviews and qualitative research techniques involving open interviews, case studies and focus groups. Among other results, the indexed Redalyc 27.1% (76) publications; and Pereira and Fonseca & Veiga represented 2.33% of authorship. The Journal of School Violence e Archives of Scientific Psychology published 12% (32) of the articles. The typological classification research most cited publications were cross-sectional studies, with 35.8% (96). The most cited screening tools were Olweus Bullying Questionnaire and SVS- Vitimization Scale School, both representing 35.5% (50) of the studied texts. Content analysis allowed to classify three publications evaluation categories: (A) the definition of school violence; (B) types of aggressive and violent acts perpetrated and suffered; and (C) psychometric characteristics of school violence screening tools. In category A was predominant tendency to define and understand the phenomenon as a synonym for bullying (53%); in category B, it was found that male subjects tend to be more aggressive perpetrators of acts and violent than females. The types of acts perpetrated most often are the physical, moral, psychological and virtual. The Category C enabled us to verify the predominance of adapted and translated instruments of the English language, which highlights semantic limitations items and therefore may compromise the validity of the construct. The results of this analysis indicate the importance of this issue and the need for further study, especially that are consistent with the social and cultural contexts of Brazil.

Context: The Internet has become a vital channel for disseminating and accessing scientific literature for both the academic and industrial research needs. Nowadays, everyone has wide access to scientific literature repositories, which comprise of both “white” and “Grey” literature. The “Grey” literature, as opposed to “white” literature, is non-peer reviewed scientific information that is not available using commercial information sources such as IEEE or ACM. A large number of software engineering researchers are undertaking systematic literature reviews (SLRs) to investigate empirical evidence in software engineering. The key reason to include grey literature during information synthesis is to minimize the risk of any bias in the publication. Using the state of the art non-commercial databases that index information, the researchers can make the rigorous process of searching empirical studies in SLRs easier. This study explains the evidence of Grey literature while performing synthesis in Systematic Literature Reviews. Objectives: The goals of this thesis work are, 1. To identify the extent of usage of Grey Literature in synthesis during systematic literature reviews. 2. To investigate if non-commercial information sources primarily Google Scholar are sufficient for retrieving primary studies for SLRs. Methods: The work consists of a systematic literature review of SLRs and is a tertiary study and meta-analysis. The systematic literature review was conducted on 138 SLRs’ published through 2003 until 2012 (June). The article sources used are IEEEXplore, ACM Digital Library, Springer-Link and Science Direct. Results: For each of the selected article sources such as ACM, IEEEXplore, Springer-link and Science Direct, we have presented results, which describe the extent of the usage of Grey literature. The qualitative results discuss various strategies for systematic evaluation of the Grey literature during systematic literature review. The quantitative results comprise of charts and tables, showing the extent of Grey literature usage. The results from analysis of Google Scholar database describe the total number of primary studies that we are able to find using only Google Scholar database. Conclusion: From the analysis of 138 Systematic Literature Reviews (SLRs’), we conclude that the evidence of Grey literature in SLRs is around 9%. The percentage of Grey literature sources used in information synthesis sections of SLRs is around 93.2%. We were able to retrieve around 96 % of primary studies using Google Scholar database. We conclude that Google Scholar can be a choice for retrieving published studies however; it lacks detailed search options to target wider pool of articles. We also conclude that Grey literature is widely available in this age of information. We have provided guidelines in the form of strategies for systematic evaluation of Grey literature. / Sammanhang: Internet har blivit en viktig kanal för att sprida och få tillgång vetenskaplig litteratur för både akademiska och industriella forskningsbehov. Numera har alla bred tillgång till vetenskaplig litteratur förråd, som omfattar både "vit" och "grå" litteratur. Den "grå" litteratur, som motsats till "vita" litteratur, är icke-vetenskapligt granskad vetenskaplig information som inte är tillgänglig med kommersiella informationskällor såsom IEEE och ACM. Ett stort antal forskare software engineering genomför systematiska litteraturöversikter (systemkameror) för att undersöka empiriska bevis programvaruteknik. Den viktigaste orsaken till att omfatta grå litteratur under Information syntes är att minimera risken för att partiskhet i publikationen. Använda toppmoderna icke-kommersiella databaser som indexerar information kan forskarna göra rigorösa processen att söka empiriska studier i systemkameror lättare. Denna studie förklarar bevis på grå litteratur när de utför syntes i systematiska litteraturöversikter. Mål: Målen med detta examensarbete är, 1. För att identifiera omfattningen av användningen av Grey litteratur i syntes under systematisk litteratur recensioner. 2. För att undersöka om icke-kommersiella informationskällor främst Google Scholar är tillräckliga för att hämta primära studier för systemkameror. Metoder: Verket består av en systematisk litteraturgenomgång av systemkameror och är en tertiär studie och metaanalys. Den systematiska litteraturstudie genomfördes på 138 systemkameror "publiceras via 2003 till 2012 (juni). Artikeln används källorna är IEEEXplore, ACM Digital Library, Springer-Link och Science Direct. Resultat: För vart och ett av de utvalda artikeln källor såsom ACM, IEEEXplore, Springer-länk och Science Direct, har vi presenterat resultat, som beskriver omfattningen av användningen av grå litteratur. De kvalitativa resultaten diskuterar olika strategier för systematisk utvärdering av grå litteratur under systematisk litteraturöversikt. De kvantitativa resultaten består av diagram och tabeller, som visar omfattningen av Grey litteratur användning. Resultaten från analys av Google Scholar-databasen beskriver det totala antalet primära studier som vi kan hitta med enbart Google Scholar databas. Slutsats: Av analysen av 138 systematiska litteraturöversikter (systemkameror) kan vi dra slutsatsen att bevisen för grå litteratur i systemkameror är cirka 9%. Den procentuella andelen Grey litteraturkällor som används i avsnitt informations syntes av systemkameror är cirka 93,2%. Vi kunde hämta omkring 96% av primära studier med Google Scholar databas. Vi drar slutsatsen att Google Scholar kan vara ett val för hämta publicerade studier dock, det saknar detaljerade sökalternativ för att rikta större pool av artiklar. Vi avslutar också att grå litteratur är allmänt tillgänglig i denna tid av information. Vi har försett riktlinjer i form av strategier för systematisk utvärdering av Grey litteratur. / Affan Yasin : Skype id (affan.yasin) Ijlal Hasnain: Skype id (bluesols)

Software Product Lines (SPL) is a relatively new way of working in software development. A SPL is an enforced architecture and a collection of components common for more than one product within a domain. Development using SPL utilizes tools and techniques for creating software systems from a common set of core assets in order to satisfy a certain market. In this study we investigate how to proceed when transitioning to a SPL development approach by evaluating proposed and used adoption approaches, methods and frameworks. We performed a systematic literature review using three main sources; Compendex/Inspec, CiteSeerX and Google Scholar. The results are analyzed using a qualitative analysis technique called Recursive Abstraction where the results are iteratively summarized to extract the essence of the data. A manageable collection of frameworks, methods and approaches are summarized as a starting point for a reader who wants to dig deeper into the subject. A set of guidelines is suggested for companies who are considering a transition to SPL development. We also investigate the link between SPL and organization maturity, with a focus on the benefits of combining a SPL initiative with a CMMI initiative. We conclude that the transition process should not be taken lightly; in most cases it should be made in incremental steps. There is a fairly standard approach to adopt SPL and there are a few frameworks that are commonly accepted. However, we also conclude that most research areas of SPL development lacks in validation. Concerning the link between SPL and CMMI we identify some PA's that are more important when considering SPL development and a few others that may be harder to execute. We conclude that SPL benefits from process maturity and discipline as SPL development is process controlled and a lack in process discipline may cause corrosion of the SPL. A CMMI maturity level of Defined processes should be considered a prerequisite for a complete SPL practice. We could not find any indication that the organization maturity would benefit from SPL practices alone. Neither could we identify any drawbacks of having both an CMMI initiative and SPL transition initiative within the same organization.

Bakgrund: Att förlora ett barn är det värsta tänkbara som kan ske i livet. Sorgen som kommer med förlusten är tid- och energikrävande. Många förlustdrabbade föräldrar klarar av hanteringen av sorgen vid förlusten, men många föräldrar gör det inte. Klarar föräldrarna inte av att hantera sorgen finns risken för en långdragen sorgereaktion/kronisk sorg. Detta kan leda till sjukskrivningar på grund av psykisk ohälsa. Det är därför viktigt att sjuksköterskan har kunskap om detta område för att kunna sätta in relevanta resurser. Syfte: Syftet var att utforska hur föräldrar hanterar sin sorg efter förlusten av ett barn. Metod: Litteraturöversikt är metoden som används för detta arbete. Databaser som användes för datainsamlingen var CINAHL Complete, PubMed, Nurse and Allied Health Database och PsychInfo. De tio vetenskapliga artiklarna som framkom i sökningarna har analyserats enligt Fribergs analysmetod där likheter och skillnader studerats i hur föräldrar hanterar sorgen efter förlusten av ett barn. Resultat: Resultatet redovisar de fyra teman som framkom i analysen av datan. 1) Stöd; 2) Bevara minnet av barnet; 3) Skapa ett nytt vardagsliv; 4) Att vila i sin tro: mening och acceptans. I dessa fyra teman redovisas ytterligare underteman för att förtydliga resultatet. Diskussion: I diskussionen hanteras resultatet med annan litteratur. Vikten av ett gott stöd och socialt nätverk vid en förlust. I diskussionen redogörs även symboler och ritualens påverkan på människan efter en förlust och meningen med att förlora en nära relation och att kunna acceptera döden. Sist redovisas genusskillnader i relation till hantering av sorg. I diskussionen implementeras teorin pendlingsmodellen av Stoebe och Schut. / Background: The loss of a child is the most devastating bereavement a parent can experience. The grief that comes with the loss is both time and energy-consuming. Many parents can cope with the grief that arises, however some parents do not. If the bereaved parents cannot cope with the grief they run the risk of developing long-term/chronic grief. The mental illness caused by the sorrow can lead to absence from work for the bereaved parents. It is therefore important that nurses have a good understanding of this subject in order for them to be able to take the best course of action. Aim: The aim of this study is to explore how parents cope with their grief after the death of their child. Method: This study is a literature review. The databases that were used for the data collection were CINAHL Complete, PubMed, Nurse and Allied Health Database and PsycInfo. The ten scientific articles found in the searches performed were analyzed by using Friberg´s method of analysis where similarities and differences in how bereaved parents cope with the grief was examined Results: The result is presented in four themes that were discovered in the data analysis. 1) Support; 2) Embalm the memory of the child; 3) Create a new daily life; 4) Rest in belief: meaning and acceptance. Discussion: In the discussion, the result is compared to other literature. When experiencing bereavement the social support is significant. The effects of Symbols and rituals on bereaved people are presented, as is the meaning found in the loss of a close relationship and being able to accept death. Finally, gender differences in coping with grief are described. Dual Process model of coping by Stroebe and Schut is implemented in the discussion.

Bakgrund: En av hälso-och sjukvårdens största utmaningar idag är att leverera säker vård i takt med att mer avancerad vård finns att tillgå. Med avancerad vård ökar risker för patientsäkerheten. I takt med utvecklingen ställs högre krav på sjuksköterskans effektivitet, kliniska och praktiska kunskaper att hantera medicinsk teknik bedriva omvårdnad samt arbeta mot patientsäkerhet. Sjuksköterskans arbetsmiljö i relation till patientsäkerheten är därför av vikt att belysa. Syfte: Att, genom en litteraturöversikt, undersöka förhållandet mellan arbetsmiljö och patientsäkerhet. Metod: Litteraturöversikt. Vetenskapliga studier har sökts i databaserna CINAHL och PubMed. Resultatet baserades på 12 vetenskapliga studier, fyra kvalitativa studier och åtta kvantitativa studier. Resultat: Resultatet genererade i fyra huvudområden: Integrerat arbete för förbättrad arbetsmiljö och patientsäkerhet: Kvaliteten på sjuksköterskans arbetsmiljö och patientsäkerhet har ett samband, bristande arbetsmiljö resulterade i bristande patientsäkerhet. Arbetsbelastning och patientsäkerhet: För högt patientantal per sjuksköterska ledde till ökad arbetsbelastning vilket äventyrade patientsäkerheten. Arbetsrelaterad stress bidrog inte till god och säker omvårdnad då sjuksköterskornas förmåga att bedriva patientsäker omvårdnad försämrades. Avvikelserapportering och patientsäkerhet: Bristfällig rapportering av avvikelser korrelerade med kvaliteten på arbetsmiljön, flertalet studier påvisade att underrapporteringen berodde på tidsbrist och att avvikelserna kunde hållas emot sjuksköterskorna. Kollegialt stöd och patientsäkerhet: Goda relationer över professionsgränserna och strukturerad handledning genererade i förbättrad arbetsmiljö och ökad patientsäkerhet. Slutsats: Litteraturöversikten styrker att det finns samband mellan arbetsmiljö och patientsäkerhet, förbättrad arbetsmiljö ger ökad kostnadseffektivitet och ökad kvalitet på omvårdnaden samt minskat antal vårdskador. / Background: One of healthcare's biggest challenges today is to deliver safe care as a progressive development. The more complex healthcare care is performed, more risks for patient safety follow. In line with development, higher demands are placed on the nurse's effectiveness, clinical and practical knowledge, medical technology, nursing and patient safety. Nursing's work environment in relation to patient safety is therefore important to highlight. Aim: To study, through a literature review, the relationship between the working environment and patient safety. Method: literature review. Scientific articles have been searched in the CINAHL and PubMed databases. The result was based on 12 scientific studies, four qualitative studies and eight quantitative studies. Result: The result generated in four main areas: Integrated work for improved work environment and patient safety: The quality of the nurse's work environment and patient safety has a connection, lack of working environment resulted in insufficient patient safety. Workload and patient safety: Too high patient number per nurse led to increased workload which endangered patient safety. Work-related stress did not contribute to good and safe nursing when the nurses' ability to perform patient-safe nursing was impaired. Deviation reporting and patient safety: Inadequate reporting of discrepancies correlated with the quality of the work environment, most studies showed that the under reporting was due to lack of time and that the abnormalities could be held against the nurses. Collegial support and patient safety: Good relations across professional boundaries and structured tutoring generated in an improved work environment and increased patient safety. Conclusion: The literature review confirms that there is a correlation between work environment and patient safety, improved work environment, increased cost-effectiveness and increased quality of care and reduced number of healthcare injuries.

Bakgrund: De som lever med hjärtsvikt är en stor patientgrupp i Sverige. Tidigare forskning påvisar att egenvård är viktigt vid en kronisk sjukdom. Sjuksköterskans roll är att utbilda och informera patienter om egenvårdsåtgärder. Det eftersträvas att patienten själv ska känna igen symtom, tecken och försämring för att kunna utföra god egenvård. Syfte: Beskriva erfarenheter av egenvård hos patienter med hjärtsvikt utifrån Riegel et al. egenvårdsmodell. Metod: Litteraturöversikten har genomförts utifrån kvalitativ metod och deduktiv ansats. En egenvårdsmodell har använts som teori och en kvalitativ analysmodell har använts i analysprocessen där 12 vetenskapliga artiklar har granskats. Resultat: Patienter med hjärtsvikt beskrev ett behov av att bland annat utforma strategier, ha ett socialt stöd och uppleva psykiskt välbefinnande för att förbättra upplevelsen av egenvård uttryckt från egenvårdsmodellens kategorier self-care maintenance, self-care monitoring och self-care management. Slutsats: Patienternas anpassning i vardagen, psykiska välbefinnande och sociala samhörighet påverkade egenvård. Sjuksköterskan kan utifrån litteraturöversikten få en ökad förståelse för individens upplevelser vilket förväntas påverka bemötandet och utformandet av den personcentrerade omvårdnaden.

Background: Heart failure is seen as a global public disease, it is one of the most common public diseases in Sweden today. The guidelines for treatment of heart failure include recommendations for physical exercise. Treatment-methods are constantly evolving, the focus of this study is on physical exercise, which is most relevant in society. Purpose: To describe the effect of physical exercise / activity in people with heart failure. Method: The literature review studied articles with a quantitative approach. Nine articles were included in the study. Results: Only results with a positive significant effect of physical exercise in people with heart failure could be found. The training methods that was used were walking-training, aerobics, cycling and interval training. Conclusion: The overview has provided knowledge of the positive impact of physical exercise for people with heart failure. In practice, the nurse provides evidence to motivate people with heart failure to an active life where there are no reasons for fear of movement.

Context: Software development in a setting in which the development sites are dispersed across geographical areas, either close proximity or globally, is fast becoming a widespread trend. This software development arrangement is also known as Global Software Development (GSD) or Distributed Software Development (DSD) or Global Software Engineering (GSE). Projects executed by a dispersed team have been noted as a more risky and challenging venture than projects run with teams under the same roof. Therefore the knowledge of the potential challenges and the probable mitigation strategies for GSD is vital for running a successful project. Objectives: The study entails the identification of GSD related challenges as well as their mitigation strategies. The collected challenges and mitigation strategies are later compiled into checklists. The developed checklists can be incorporated into risk management process particularly risk identification and risk mitigation planning. Methods: This research extends an existing systematic literature study conducted on empirical research on GSD, which was based on a review of publications from 2000 to 2007. The previous research is incorporated in this research and, in addition, papers between 2007 and 2009 are reviewed. In contrast to the previous research was aimed at gathering empirical evidence in GSD, however in this research the focus is specifically on challenges associated with GSD projects as well as the mitigation strategies that can be employed. An industrial survey was also conducted to validate the checklists and determine if the identified challenges and mitigation strategies were pervasive in industry. Furthermore interviews were also conducted to further validate the usefulness and usability of the developed checklists. Result: As a result, from the systematic literature review for publications between 2000 and 2009, a total of 48 challenges and 42 mitigation strategies were identified and placed in two separate categorized checklists. These challenges and mitigation strategies are elaborated in this paper. From the survey result, no additional challenges and 4 strategies were identified in the survey. Meanwhile from the interviews, all interviewees reported that the checklists are useful and easy to use. Conclusion: The absence of new challenges being identified from the study did not merit a conclusion that all possible challenges in GSD have been revealed. Therefore we conclude that more empirical research still needs to be done on identifying the challenges and mitigation strategies associated with GSD settings. Furthermore the checklists can be useful and valuable in identifying challenges and the potential mitigation strategies for communication, control and coordination mechanisms in distributed software development projects.

Context: In the last decade, Agile software development methods were proposed as a response to plan-driven methods. The main aim for this paradigm shift was to cope up with constant changes. Core values that are central to agile methods are described in Agile Manifesto. Agile practices define how agile methods are implemented in practice. Objectives: This study aims to investigate what practices were considered and adopted as part of agile philosophy, and identify evidence on the use of agile practices in reference to what defines agile. Methods: We conducted a systematic literature review. The review includes 186 primary studies published between 2000 and 2010. Quality assessment based on rigor and relevance as identified in the selected papers has been conducted. Non-empirical papers were classified based on themes they addressed. Empirical papers were analyzed based on two factors: 1. if they described the use of agile practices for a software project/product in general, 2. if they described the use of agile practices for a specific purpose/activity Application type, team size and experience of subjects in the primary studies were extracted. The alignment between practices reported in the studies with the core agile values is analyzed. Results: A total of 119 studies were conducted in industry and 67 in academia. Nearly half the papers published by researchers are non-empirical and present analysis of agile practices in various topics. Over half of the empirical papers were focused on evaluation/assessment of a specific aspect of agile. ‘Pair programming’ received most attention in this direction. Among the empirical studies that described agile practices for academic projects, ‘Pair programming’ and ‘Test driven development’ were the most considered practices. Among the 119 studies conducted in industry, 93 studies described the use of agile practices for the overall project/product development while the remaining studies described experiences of single practices like Pair Programming or the modification/adoption of agile for non-software aspects in software projects. Practices adopted have been ranked based on team size, practitioners’ experience and application type. A method for agile assessment based on core agile values is developed and exemplified. Conclusions: Practices that are considered agile vary with context although ‘Pair programming’, ‘Continuous integration’, ‘Refactoring and Testing continuous throughout the project are the most common practices used. ‘Test driven development’ was not highly adopted by practitioners. But it was not clear if test cases were written before code construction in projects where continuous testing was performed. However, this was completely opposite in academic projects. Practices ‘On-site frequently modified. In many of the studies inspected, practices adopted were not aligned with agile values. Although practices related to technical aspects of software development are in place, agile practices that focus aspects like ‘working together’ and ‘motivated individuals’ are often not used in practice. Moreover, many of the studies were not reported to an extent that it was possible to draw any inferences on the usability/applicability, benefits and limitations of the agile practices. To this end, a major implication is to improve the quality of the studies and a need for a common framework to report the results of agile practices’ adoption.
