software start-ups are aiming to develop cutting-edge software products under highly uncertain conditions, overcoming fast-growing markets under multiple influences. This study aims to identify and analyse the existing scientific literature regarding software development methodologies and practices in software start-ups published between January 2006 and December 2017 using the systematic mapping study. The results identified 37 relevant primary studies out of 1982 papers. To validate the results from the mapping study, an empirical study was based on the research data collected from 14 real-life software start-ups located in Finland, Italy and Norway. The result shows that Agile and Lean start-up methodologies are the most commonly used in software start-ups due to the flexible nature and easy tailoring. A total of 144 software development work practices are extracted from the primary studies. This study contributes to the research in several ways: (i) provides state of the art regarding software development methods and practices in software start-up contexts, (ii) reports commonly used methods along with its benefits identified in primary studies and (iii) identifies opportunities for future software start-up research.

The theories of social exchange, task-technology fit, and technology acceptance are utilized in a field study of software development methodologies. This investigation includes the effects of user experiences on perceptions of acceptance and usage of a methodology. More specifically, perceptions of the outputs and deliverables from a methodology and perceptions of challenges and obstacles to using and applying a methodology were found to significantly and positively influence perceived usefulness and negatively influence ease of use of a methodology, respectively, within a developer's organization. Perceived usefulness was a positive and strong antecedent to perceptions of fit between the methodology and client problems, and the strengthening of efficacy beliefs about the methodology.

Choice of software development methodologies Do Organizational, Project, and Team Characteristics Matter?

引用

IEEE software 2016年第5期33卷 86-94页

作者： Vijayasarathy, Leo R. Butler, Charles W. Colorado State Univ Comp Informat Syst Ft Collins CO 80523 USA

Organizations can choose from software development methodologies ranging from traditional to agile approaches. Researchers surveyed project managers and other team members about their choice of methodologies. The results indicate that although agile methodologies such as Agile Unified Process and Scrum are more prevalent than 10 years ago, traditional methodologies, including the waterfall model, are still popular. Organizations are also taking a hybrid approach, using multiple methodologies on projects. Furthermore, their choice of methodologies is associated with certain organizational, project, and team characteristics.

A metamodel for assessable software development methodologies

引用

software QUALITY JOURNAL 2005年第2期13卷 195-214页

作者： Gonzalez-Perez, C McBride, T Henderson-Sellers, B Univ Technol Sydney Fac Informat Technol Dept Sofware Engn Sydney NSW 2007 Australia

software development methodologies usually contain guidance on what steps to follow in order to obtain the desired product. At the same time, capability assessment frameworks usually assess the process that is followed on a project in practice in the context of a process reference model, defined separately and independently of any particular methodology. This results in the need for extra effort when trying to match a given process reference model with an organisation's enacted processes. This paper introduces a metamodel for the definition of assessable methodologies, that is, methodologies that are constructed with assessment in mind and that contain a built-in process reference model. Organisations using methodologies built from this metamodel will benefit from automatically ensuring that their executed work conforms to the appropriate assessment model.

Modelling software development methodologies: A conceptual foundation

JOURNAL OF SYSTEMS AND software 2007年第11期80卷 1778-1796页

Current modelling approaches often purport to be based on a strong theoretical underpinning but, in fact, contain many ill-defined concepts or even contradictions leading to potential misinterpretation. Although much modelling in object-oriented contexts is focussed on the use of the Unified Modelling Language (UML), this paper presents a technology-agnostic approach that analyses the basic concepts of structural models and modelling in software engineering, using an approach based on representation theory. We examine the different kinds of interpretive mappings (either isotypical, prototypical or metatypical) that are required in order to trace model entities back to the SUS (subject under study) entities that they represent. The difference between forward- and backward-looking models is also explained, as are issues relating to the appropriate definition of modelling languages in general based on representation theory. The need for product and process integration in methodologies is then addressed, leading to the conclusion that a mesh of verbal plus nominal nodes is necessary in any methodology metamodel. Finally, the need for a common, cross-cutting modelling infrastructure is established, and a solution proposed in the form of an ontologically universal modelling language, OOLang. Examples of the application of these theoretical analyses to the suite of OMG products (particularly SPEM, UML and MOF) are given throughout, with the hope that awareness of the importance of a better modelling infrastructure can be developed.

This work aims at evaluating a graphical notation for modelling software (and other kinds of) development methodologies, thus demonstrating how useful the graphical aspects can be for sharing knowledge between the people responsible for documenting information and those responsible for understanding and putting it into practice. We acknowledge the importance of having a common set of symbols that can be used to create, use and disseminate information for a larger audience than is possible today with a variety of alternatives and lack of a common ground. Using a cognitive dimensions framework, we make a standard evaluation of the elements and diagrams of the notation proposed to support the ISO/IEC 24744 methodology metamodel standard, considering the trade-offs between different dimensions. We suggest improvements to this existing notation based on this analysis, in the context of improving communication between creators and users of methodologies. (C) 2012 Elsevier Ltd.

The last few years have seen a growing development of software industry in East Africa and Tanzania in particular. The software industry has contributed up to 40% of the economic growth in the past 10 years with the number of registered firms increasing yearly. Despite these developments, few studies have investigated the software development methodologies and practices that have been applied in the software industry and how they affect the success or failure of the software projects. This study investigated software development activities in 18 firms to determine to what extent the software development methods are being adopted and the factors influencing the selection of such methodologies. The study used questionnaire, semi-structured interviews, and documentary review involving 54 developers and project managers from 18 software firms in Dar es Salaam, Tanzania. The study found that the majority of software firms have been adopting traditional software development methodologies accounting to 72% of 79 studied software products. Specifically, amongst 51 software products developed using traditional software methodology, nearly half of the software products adopted waterfall model. Moreover, agile methodologies and other iterative methods are rarely adopted in the software industry. The implications of the results are discussed.

INDUSTRIAL AND COMMERCIAL TRAINING 2018年第7-8期50卷 380-392页

作者： Balle, Andrea Raymundo Oliveira, Mirian Curado, Carla Nodari, Felipe Pontificia Univ Catolica Rio Grande do Sul Sch Business Porto Alegre RS Brazil Univ Lisbon Dept Management ISEG Lisbon Portugal

Purpose The purpose of this paper is to illustrate how knowledge takes effect in different software development methodologies by relating them to different knowledge cycles. Design/methodology/approach The results were find by conducing a general review about the topics of knowledge cycles and software development methodologies. Findings All software development methodologies have knowledge cycles. In Waterfall methodology, the cycle followed is I-Space. For code and fix, there is a parallel with March's cycle. Scrum shows a parallel with SECI cycle. Among the methodological options, results show there an increase in hierarchy, documentation, processes and explicit knowledge. Research limitations/implications Identified parallels of each methodology with knowledge cycles;established which Scrum artifacts are performed at each stage of SECI, which Waterfall steps correspond to I-Space phases and which activities in code and fix deal with exploration and exploitation of knowledge;and features shown increase or decrease according to the adoption of each methodology. Practical implications Results help knowledge sharing implementations and foster inter-team knowledge sharing, with the identification of the correct methodology-cycle match and the personalization of the strategy for each team based on the adopted methodology. Training for knowledge initiatives can be improved by determining how knowledge-sharing activities are incorporated on the determined series of actions established by the methodologies adopted on the firm. Originality/value The identification of how knowledge is generated and shared among teams in each methodology, the optimum pairing of the methodology and the parallels with the other, and the differences that emerge from the adopted knowledge cycle show that software projects are embedded in a knowledge cycle.

A Framework for the Prototype-based software development methodologies

Journal of King Saud University - Computer and Information Sciences 2001年 13卷 111-131页

In the object-oriented paradigm, two techniques, class-based technique and prototype-based technique are available for modeling the real-world objects. In this paper, we first study and analyze both object-modeling techniques, then using this study and analysis we identify a class of applications, and argue that the class-based methodologies that use the class-based technique as the object-modeling technique, are inappropriate to use for the development of this class of applications. Considering the requirements of the identified class of applications, we argue for need of a class of software development methodologies which are referred to as the prototype-based methodologies . In this paper, we also propose modifications in the classical Water-Fall life-cycle software development model, which make it consistent with the requirements of the prototype-based methodologies. The modified life-cycle model provides a framework and basic guidelines for proposing the prototype-based methodologies.
