The role of IT in organizational innovation – A systematic literature review

Information technology (IT) is broadly recognized as an important element in organizational innovation, however there has been relatively little integration of Information Systems (IS) research on the role of IT in organizational innovation. Such integration is particularly important in view of recent calls to examine the evolving ontological nature of IT, wherein IT artifacts are now shaping physical reality. We systematically examine innovation-related literature published in the leading IS journals in the period between 2009 and 2020 and we identify and summarize the core theoretical discourses in this domain. We find that extant literature largely examines the role of IT in innovation at a high level of abstraction, focusing on IT investments and IT capabilities, and consequently precluding granular insights on who, what, when, where, how, and why in relation to organizational innovation. To address this limitation and to provide a structuring lens for future research, we develop the organizational innovation system framework which posits that actors, IT artifacts, actions and organizational context are the key elements in organizational innovation systems that require more granular examination to yield deeper insights on how information technology contributes to organizational innovation. We re-examine the literature through the organizational innovation system lens and we identify gaps in extant research. We also outline potential directions for expanding the scope of future research.     

The impact of global dispersion on coordination,team performance and software quality – A systematic literature review

ContextGlobal software development (GSD) contains different context setting dimensions, which are essential for effective teamwork and success of projects. Although considerable research effort has been made in this area, as yet, no agreement has been reached about the impact of these dispersion dimensions on team coordination and project outcomes.ObjectiveThis paper summarizes empirical evidence on the impact of global dispersion dimensions on coordination, team performance and project outcomes.MethodWe performed a systematic literature review of 46 publications from 25 journals and 19 conference and workshop proceedings, which were published between 2001 and 2013. Thematic analysis was used to identify global dimensions and their measures. Vote counting was used to decide on the impact trends of dispersion dimensions on team performance and software quality.ResultsGlobal dispersion dimensions are consistently conceptualized, but quantified in many different ways. Different dispersion dimensions are associated with a distinct set of coordination challenges. Overall, geographical dispersion tends to have a negative impact on team performance and software quality. Temporal dispersion tends to have a negative impact on software quality, but its impact on team performance is inconsistent and can be explained by type of performance.ConclusionFor researchers, we reveal several opportunities for future research, such as coordination challenges in inter-organizational software projects, impact of processes and practices mismatches on project outcomes, evolution of coordination needs and mechanism over time and impact of dispersion dimensions on open source project outcomes. For practitioners, they should consider the tradeoff between cost and benefits while dispersing tasks, alignment impact of dispersion dimensions with individual and organizational objectives, coordination mechanisms as situational approaches and collocation of development activities of high quality demand components in GSD projects.     

Empirical studies on the use of social software in global software development – A systematic mapping study

BackgroundIn Global Software Development (GSD), informal communication and knowledge sharing play an important role. Social Software (SoSo) has the potential to support and foster this key responsibility. Research on the use of SoSo in GSD is still at an early stage: although a number of empirical studies on the usage of SoSo are available in related fields, there exists no comprehensive overview of what has been investigated to date across them.ObjectiveThe aim of this review is to map empirical studies on the usage of SoSo in Software Engineering projects and in distributed teams, and to highlight the findings of research works which could prove to be beneficial for GSD researchers and practitioners.MethodA Systematic Mapping Study is conducted using a broad search string that allows identifying a variety of studies which can be beneficial for GSD. Papers have been retrieved through a combination of automatic search and snowballing, hence a wide quantitative map of the research area is provided. Additionally, text extracts from the studies are qualitatively synthesised to investigate benefits and challenges of the use of SoSo.ResultsSoSo is reported as being chiefly used as a support for collaborative work, fostering awareness, knowledge management and coordination among team members. Contrary to the evident high importance of the social aspects offered by SoSo, socialisation is not the most important usage reported.ConclusionsThis review reports how SoSo is used in GSD and how it is capable of supporting GSD teams. Four emerging themes in global software engineering were identified: the appropriation and development of usage structures; understanding how an ecology of communication channels and tools are used by teams; the role played by SoSo either as a subtext or as an explicit goal; and finally, the surprising low percentage of observational studies.     

Empowering the users? A critical textual analysis of the role of users in open source software development

This paper outlines a critical, textual approach for the analysis of the relationship between different actors in information technology (IT) production, and further concretizes the approach in the analysis of the role of users in the open source software (OSS) development literature. Central concepts of the approach are outlined. The role of users is conceptualized as reader involvement aiming to contribute to the configuration of the reader (to how users and the parameters for their work practices are defined in OSS texts). Afterwards, OSS literature addressing reader involvement is critically reviewed. In OSS context, the OSS writers as readers configure the reader and other readers are assumed to be capable of and interested in commenting the texts. A lack of OSS research on non-technical reader involvement is identified. Furthermore, not only are the OSS readers configured, but so are OSS writers. In OSS context while writers may be empowered, this clearly does not apply to the non-technical OSS readers. Implication for research and practice are discussed.

Characterizing logging practices in Java-based open source software projects – a replication study in Apache Software Foundation

Log messages, which are generated by the debug statements that developers insert into the code at runtime, contain rich information about the runtime behavior of software systems. Log messages are used widely for system monitoring, problem diagnoses and legal compliances. Yuan et al. performed the first empirical study on the logging practices in open source software systems. They studied the development history of four C/C++ server-side projects and derived ten interesting findings. In this paper, we have performed a replication study in order to assess whether their findings would be applicable to Java projects in Apache Software Foundations. We examined 21 different Java-based open source projects from three different categories: server-side, client-side and supporting-component. Similar to the original study, our results show that all projects contain logging code, which is actively maintained. However, contrary to the original study, bug reports containing log messages take a longer time to resolve than bug reports without log messages. A significantly higher portion of log updates are for enhancing the quality of logs (e.g., formatting & style changes and spelling/grammar fixes) rather than co-changes with feature implementations (e.g., updating variable names).     

Past and future of software architectural decisions – A systematic mapping study

ContextThe software architecture of a system is the result of a set of architectural decisions. The topic of architectural decisions in software engineering has received significant attention in recent years. However, no systematic overview exists on the state of research on architectural decisions.ObjectiveThe goal of this study is to provide a systematic overview of the state of research on architectural decisions. Such an overview helps researchers reflect on previous research and plan future research. Furthermore, such an overview helps practitioners understand the state of research, and how research results can help practitioners in their architectural decision-making.MethodWe conducted a systematic mapping study, covering studies published between January 2002 and January 2012. We defined six research questions. We queried six reference databases and obtained an initial result set of 28,895 papers. We followed a search and filtering process that resulted in 144 relevant papers.ResultsAfter classifying the 144 relevant papers for each research question, we found that current research focuses on documenting architectural decisions. We found that only several studies describe architectural decisions from the industry. We identified potential future research topics: domain-specific architectural decisions (such as mobile), achieving specific quality attributes (such as reliability or scalability), uncertainty in decision-making, and group architectural decisions. Regarding empirical evaluations of the papers, around half of the papers use systematic empirical evaluation approaches (such as surveys, or case studies). Still, few papers on architectural decisions use experiments.ConclusionOur study confirms the increasing interest in the topic of architectural decisions. This study helps the community reflect on the past ten years of research on architectural decisions. Researchers are offered a number of promising future research directions, while practitioners learn what existing papers offer.     

Does peer assessment in on-line learning environments work? A systematic review of the literature

There is an increase use of Peer Assessment (PA) approaches in On-line Learning Environments to support students and teachers on educational process. However, the community still lacks a comprehensive understanding of how Peer Assessment behaves within these educational environments, since there are no studies that make an analysis of the researches which has been conducted in this context, analysing the benefits and disadvantages of the use of Peer Assessment. Thus, the main goal of this work is to investigate and better understand how PA contributes in student learning as well as can bring benefits to the teachers involved. In order to meet our goal, we conducted a systematic literature review (SLR). In summary, the main findings are: (1) there are empirical evidences of the benefits of using PA in both industry and academy, and in several educational levels; (2) PA is most addressed to the correction of written activities on on-line courses; (3) About 60% of the articles showed PA improvement in student performance; (4) About 1/3 of the studies showed PA brings some benefits to teachers; (5) In some studies the use of the PA had difficulties, especially issues related to student motivation, which impairs the peer review process.     

State of the art in damage information modeling for RC bridges – A literature review

In Germany, bridges have an average age of 40 years. A bridge consumes between 0.4% and 2% of its construction cost per year over its entire life cycle. This means that up to 80% of the construction cost are additionally needed for operation, inspection, maintenance, and destruction. Current practices rely either on paper-based inspections or on abstract specialist software. Every application in the inspection and maintenance sector uses its own data model for structures, inspections, defects, and maintenance. Due to this, data and properties have to be transferred manually, otherwise a converter is necessary for every data exchange between two applications. To overcome this issue, an adequate model standard for inspections, damage, and maintenance is necessary. Modern 3D models may serve as a single source of truth, which has been suggested in the Building Information Modeling (BIM) concept. Further, these models offer a clear visualization of the built infrastructure, and improve not only the planning and construction phases, but also the operation phase of construction projects. BIM is established mostly in the Architecture, Engineering, and Construction (AEC) sector to plan and construct new buildings. Currently, BIM does not cover the whole life cycle of a building, especially not inspection and maintenance. Creating damage models needs the building model first, because a defect is dependent on the building component, its properties and material. Hence, a building information model is necessary to obtain meaningful conclusions from damage information. This paper analyzes the requirements, which arise from practice, and the research that has been done in modeling damage and related information for bridges. With a look at damage categories and use cases related to inspection and maintenance, scientific literature is discussed and synthesized. Finally, research gaps and needs are identified and discussed.     

The faster the better? Innovation speed and user interest in open source software

It is often believed that for open source software (OSS) projects the faster the release, the better for attracting user interest in the software. Whether this is true, however, is still open to question. There is considerable information asymmetry between OSS projects and potential users as project quality is unobservable to users. We suggest that innovation speed of OSS project can signal the unobservable project quality and attract users’ interest in downloading and using the software. We contextualize innovation speed of OSS projects as initial release speed and update speed and examine their impacts on user interest. Drawing on the signaling theory, we propose a signaling effect through which a higher initial release speed or update speed increases user interest, while the effect diminishes as initial release or update speed increases. Using a large-scale panel data set from 7442 OSS projects on SourceForge between 2007 and 2010, our results corroborate the inverted U-shaped relationships between initial release speed and user downloads and between update speed and user downloads.     

Design science research contribution to business intelligence in the cloud — A systematic literature review

Business intelligence (BI) helps managers make informed decisions. In the age of big data, BI technology provides essential support for decision making. Cloud computing also attracts many organizations because of its potential: ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and services). This paper focuses on the deployment of BI in the cloud, from the vantage point of design science research (DSR). We produce a state of the art of research pertaining to BI in the cloud, following the methodology of systematic literature review. This literature review especially exhibits the different artifacts proposed by design science researchers regarding BI in the cloud. To structure the literature review, we propose a framework composed of two dimensions: artifact type and BI step. In particular, we propose a typology of artifact types, refining the coarse-grained typology commonly used in DSR. We use the two-dimensional framework both to map the current state of DSR regarding BI in the cloud, and to elicit future research avenues in terms of design science artifacts for BI in the cloud. The contribution is threefold: the literature review may help DSR researchers get an overview of this active research domain; the two-dimensional framework facilitates the understanding of different research streams; finally, the proposed future topics may guide researchers in identifying promising research avenues.     

The Tarpit – A general theory of software engineering

ContextRecent years have seen an increasing interest in general theories of software engineering. As in other academic fields, these theories aim to explain and predict the key phenomena of the discipline.ObjectiveThe present article proposes a general theory of software engineering that we have labeled the Tarpit theory, in reference to the 1982 epigram by Alan Perlis.MethodAn integrative theory development approach was employed to develop the Tarpit theory from four underlying theoretical fields: (i) languages and automata, (ii) cognitive architecture, (iii) problem solving, and (iv) organization structure. Its applicability was explored in three test cases.ResultsThe theory demonstrates an explanatory and predictive potential for a diverse set of software engineering phenomena. It demonstrates a capability of explaining Brooks’s law, of making predictions about domain-specific languages, and of evaluating the pros and cons of the practice of continuous integration.ConclusionThe presented theory appears capable of explaining and predicting a wide range of software engineering phenomena. Further refinement and application of the theory remains as future work.     

Lost in optimisation of water distribution systems? A literature review of system operation

Optimisation of the operation of water distribution systems has been an active research field for almost half a century. It has focused mainly on optimal pump operation to minimise pumping costs and optimal water quality management to ensure that standards at customer nodes are met. This paper provides a systematic review by bringing together over two hundred publications from the past three decades, which are relevant to operational optimisation of water distribution systems, particularly optimal pump operation, valve control and system operation for water quality purposes of both urban drinking and regional multiquality water distribution systems. Uniquely, it also contains substantial and thorough information for over one hundred publications in a tabular form, which lists optimisation models inclusive of objectives, constraints, decision variables, solution methodologies used and other details. Research challenges in terms of simulation models, optimisation model formulation, selection of optimisation method and postprocessing needs have also been identified.     

Does the technology acceptance model predict actual use? A systematic literature review

ContextThe technology acceptance model (TAM) was proposed in 1989 as a means of predicting technology usage. However, it is usually validated by using a measure of behavioural intention to use (BI) rather than actual usage.ObjectiveThis review examines the evidence that the TAM predicts actual usage using both subjective and objective measures of actual usage.MethodWe performed a systematic literature review based on a search of six digital libraries, along with vote-counting meta-analysis to analyse the overall results.ResultsThe search identified 79 relevant empirical studies in 73 articles. The results show that BI is likely to be correlated with actual usage. However, the TAM variables perceived ease of use (PEU) and perceived usefulness (PU) are less likely to be correlated with actual usage.ConclusionCare should be taken using the TAM outside the context in which it has been validated.     

Virtual or vague? a literature review exposing conceptual differences in defining virtual organizations in IS research

The concept of ??virtual organization?? was coined about 15?years ago to describe changes in organizational structures and value creation, enabled by the affordances of ICT. Not surprisingly, the Information Systems community has been influential in researching virtual organization phenomena. However, it appears that, since the notion of ??virtual?? in its most basic connotation only denotes some form of difference to a ??traditional?? form of organization, the term VO has been interpreted in varied form with an unsatisfying mix of VO notions existing in the literature. What is more, papers frequently exhibit mismatches between what they characterize as VO and the real-life phenomena they discuss. Motivated by these observations we carry out a literature analysis to explore differing notions of virtual organization. Based on a systematic classification of VO definitions, we uncover three distinct types of VO that are used in the literature, each of which interprets the notion of ??virtual?? differently, but is useful in its own right and exhibits unique management challenges. The first type, named Internal VO, revolves around internal virtualization based on distributed collaboration in virtual teams. It emerged on the back of emerging new groupware and communication technologies. Its main challenges stem from distributed project and work organization. The second type, named Network VO, describes a network of smaller companies that form a virtual entity, bringing in core competencies in short term collaborative projects. It emerged on the back of a emerging inter-organizational information systems and a trend of forming network arrangement. Its main challenges are with the governance of the multi-entity network. The third type, termed Outsourcing VO, refers to a hierarchical network of suppliers to which the focal firm outsources a significant part of its value creation, thus appearing as a virtual firm. It emerged on the back of the outsourcing trend of the last decades. Its main challenge is determining the optimal degree of integration and virtualization. With the identification and detailed exploration of the three VO types, our study contributes to a better understanding of the conceptual foundation of VO research and points to the necessity for conceptual clarity in future research.     

Is software “green”? Application development environments and energy efficiency in open source applications

Context

The energy efficiency of IT systems, also referred to as Green IT, is attracting more and more attention. While several researchers have focused on the energy efficiency of hardware and embedded systems, the role of application software in IT energy consumption still needs investigation.

Objective

This paper aims to define a methodology for measuring software energy efficiency and to understand the consequences of abstraction layers and application development environments for the energy efficiency of software applications.

Method

We first develop a measure of energy efficiency that is appropriate for software applications. We then examine how the use of application development environments relates to this measure of energy efficiency for a sample of 63 open source software applications.

Results

Our findings indicate that a greater use of application development environments - specifically, frameworks and external libraries - is more detrimental in terms of energy efficiency for larger applications than for smaller applications. We also find that different functional application types have distinctly different levels of energy efficiency, with text and image editing and gaming applications being the most energy inefficient due to their intense use of the processor.

Conclusion

We conclude that different designs can have a significant impact on the energy efficiency of software applications. We have related the use of software application development environments to software energy efficiency suggesting that there may be a trade-off between development efficiency and energy efficiency. We propose new research to further investigate this topic.     

Structuring principles of the communication architecture of open systems — A systematic approach

The ISO Reference Model for the communication of Open Systems uses a variety of structuring elements, such as system, service, layer, and protocol without really defining them. Thus, readers of the Reference Model document who are not immediately involved in the international activities for standardizing this area frequently get the impression that this communication architecture is incidental and has evolved at random. It is shown that this is not so, but that the communication architecture has a very strong inner consistency. To do so, we explain the system of the structuring principles by means of which the communication architecture is derived.

A systematic review on security in Process-Aware Information Systems – Constitution,challenges, and future directions

ContextSecurity in Process-Aware Information Systems (PAIS) has gained increased attention in current research and practice. However, a common understanding and agreement on security is still missing. In addition, the proliferation of literature makes it cumbersome to overlook and determine state of the art and further to identify research challenges and gaps. In summary, a comprehensive and systematic overview of state of the art in research and practice in the area of security in PAIS is missing.ObjectiveThis paper investigates research on security in PAIS and aims at establishing a common understanding of terminology in this context. Further it investigates which security controls are currently applied in PAIS.MethodA systematic literature review is conducted in order to classify and define security and security controls in PAIS. From initially 424 papers, we selected in total 275 publications that related to security and PAIS between 1993 and 2012. Furthermore, we analyzed and categorized the papers using a systematic mapping approach which resulted into 5 categories and 12 security controls.ResultsIn literature, security in PAIS often centers on specific (security) aspects such as security policies, security requirements, authorization and access control mechanisms, or inter-organizational scenarios. In addition, we identified 12 security controls in the area of security concepts, authorization and access control, applications, verification, and failure handling in PAIS. Based on the results, open research challenges and gaps are identified and discussed with respect to possible solutions.ConclusionThis survey provides a comprehensive review of current security practice in PAIS and shows that security in PAIS is a challenging interdisciplinary research field that assembles research methods and principles from security and PAIS. We show that state of the art provides a rich set of methods such as access control models but still several open research challenges remain.     

Theoretical foundations of human decision-making in agent-based land use models – A review

Recent reviews stated that the complex and context-dependent nature of human decision-making resulted in ad-hoc representations of human decision in agent-based land use change models (LUCC ABMs) and that these representations are often not explicitly grounded in theory. However, a systematic survey on the characteristics (e.g. uncertainty, adaptation, learning, interactions and heterogeneities of agents) of representing human decision-making in LUCC ABMs is missing. Therefore, the aim of this study is to inform this debate by reviewing 134 LUCC ABM papers. We show that most human decision sub-models are not explicitly based on a specific theory and if so they are mostly based on economic theories, such as the rational actor, and mainly ignoring other relevant disciplines. Consolidating and enlarging the theoretical basis for modelling human decision-making may be achieved by using a structural framework for modellers, re-using published decision models, learning from other disciplines and fostering collaboration with social scientists.
