Organizational Maturity Models Architectures: A Systematic Literature Review

Maturity models (MMs) are tools to assess how reliable is an organization and to identify its strengths and weaknesses. The increasing number of MMs developed for several domains or specific contexts based on different architectural styles (AS’s), makes more difficult its understanding and reuse. This paper aims to identify and compare the AS’s of organizational MMs for different domains. A Systematic Literature Review (SLR) was conducted. The SLR included 70 studies that describe the architecture of MMs for different contexts. A classification scheme was defined and tested with a group of MMs. Another group of MMs adopted the AS of existing models. As a result, the MMs found were classified into nine AS’s. The AS’s derived from SW-CMM and CMMI-staged are quite similar. The ISO-SPICE-based and the OPM3-based architectures are the most different. The AS’s most used in studies were the CMMI-based and the progression-staged model.

Agile Practices Adoption in CMMI Organizations: A Systematic Literature Review

In the recent years, the adoption of agile frameworks and methodologies in Software Development Organizations (SDO) has grown up considerably. Unfortunately, there are scenarios where agile practices can’t cover alone all the needs; for instance, software projects with a large level of required formal documentation or large, complex software projects; similarly, this kind of situations happen frequently in a context of CMMI organizations. The aim of this study is identify and analyze the most used agile practices that are used in combination with CMMI within SDO. To accomplish this, a systematic literature review has been performed according to relevant guidelines. This study has identified practices related Daily Meeting and Product Backlog management from Scrum framework as most common agile practices used in combination with CMMI. In addition, we could identify that there are specific benefits of implementing practices from both approaches.

Methodologies, Methods, Techniques and Tools Used on SLR Elaboration: A Mapping Study

The aim of this study is to perform a Systematic Literature Mapping (SLM) about methodologies, methods, techniques and tools used on the development of Systematic Literature Reviews (SLR). As a result, on the mapping, we expected to find and classify methodologies, methods, techniques and tools commonly used on SLR. In addition, we have considered other contexts such as, Medicine or Education with the purpose of getting multiple methodologies, methods, techniques and tools that allow performing SLR on efficient ways. It is mainly expected to identify techniques related to research questions formulation and the methods used for building search strings in order to get the higher number of studies associated to the research topic. In our study, we found multiple methodologies, methods, techniques and tools already implemented for performing SLRs On the mapping we describe some of them to highlight the most used and referenced studies.

Information Technology Service Management Processes for Very Small Organization: A Proposed Model

Nowadays Information Technology Services Management (ITSM) has become strongly needed for every kind of organizations providing IT services for customers or for themselves. However, existing models (as CMMI-SVC, ITIL or ISO/IEC 20000) are strongly difficult to implement on very small organizations. The aim of this article is to propose an ITSM model which can be applied in very small organization. Our methodology was: define an ITSM model considering needs and constraint in small organization, map elements to ISO/IEC 20000, and validate Model in small enterprises. The ITSM Model obtained was defined using relevance base practices from ISO/IEC 20000 and considering main characteristics of small organizations. The model proposed was validated in three small companies, with positive results.

Analysis of environmental factors in the adoption of ISO/IEC 29110. Multiple case study

The software industry comprising small companies represents an interesting opportunity for economic development. But these still have problems in productivity and the quality of their delivered products. In this context, the ISO/IEC 29110 standard has been developed, which represents an opportunity for small companies whose adoption depends on several factors, in particular, those related to the environment. In this paper, we study the influence of environmental factors on the adoption of ISO/IEC 29110 standard. For this research, a multiple case study was carried out, which includes four organizations as units of analysis. In a controlled environment, each organization implemented the processes belonging to the basic profile of the ISO/IEC 29110 standard. After the implementation, an analysis has been made of the environmental factors that influenced the adoption of the standard. Of the 16 environmental factors analyzed, it was found that 6 factors influenced all the organizations and those related to the support and trust of the partners had the greatest positive influence on the standard adoption, while the defense factor of the partners had the most negative influence. All other factors had minimal or no influence.

Project Portfolio Management in Small Context in Software Industry: A Systematic Literature Review

In recent years, the software industry in Latin America, mostly consisted of small companies, has shown a notable increase in its operations. However, the practices they use do not allow them to achieve sustainable growth over time. In particular, one aspect that stands out is the disorder that presents inside the company when managing multiple projects with a very small human team. This paper seeks to identify experiences of application of models related to portfolio management in small contexts in the software industry. The study is carried out through a systematic literature review in relevant digital repositories. We have found 60 primary studies obtained in the search in the considered databases. Primary studies show that project portfolio management models present difficulties in their adoption in small contexts. In addition, there are few studies that refer to experiences of application of portfolio management models in small context in the software industry and point out that a relevant aspect for non-adoption is the lack of understanding of the models in their original proposal.

Convergence Analysis of ISO/IEC 12207 and CMMI-DEV: Complementary Result from Systematic Literature Review

The organizations and people are demanding more and better software products and services, which implies adequate processes for its development. In the context of the software industry, there are two models, the CMMI-DEV and ISO/IEC 12207 that are influencing it. Though, they are evolving separately, recurrently they have been compared to determine its coverage (in both directions). In this study is analyzed the results of those comparisons (partials and completed) to determine if the models ISO/IEC 12207 and CMMI-DEV converge at processes level. This study identified eight articles where the comparison is carried out between ISO/IEC 12207 and CMMI-DEV. The results show that technique most used is the mapping comparisons between the models and according to the analyzed studies is not possible to determine whether there is convergence in the time. However, we found some items and criterions for use in comparisons.
