Test Process Models: Systematic Literature Review

Software products quality is strongly influenced by the quality of the process that generated them; particularly, the testing process contributes to product quality and represents a significant effort in software development projects. In this context, this study aim to find which test process models has been defined, adapted or extended in software industry from 1990 to the current date. For this purpose, a systematic literature review has been performed according to relevant guidelines. This study has identified 23 test process models, many of them adapted or extended from TMMi and TPI, which have different architectures and the new ISO/IEC 29119 with an architectural approach aligned to other ISO/IEC software process models.

Software process improvement and certification of a small company using the NTP 291 100 (moprosoft)

Today we recognize the strong influence of the software in our world and the need for it to have the right quality. However, the software industry has remained in a crisis for many years. Faced with this situation, the quality of process models are presented as an interesting opportunity that can help to change it. This article presents the experiences, challenges and lessons learned in the processes improvement and subsequent certification with the NTP 291 100 (based on MoProSoft) of a small software-development company located in the city of Arequipa in Peru.

Factors driving the adoption of ISO/IEC 29110: A case study of a small software enterprise

Peruvian software industry is mainly composed of micro and small enterprises and presents several problems on quality, schedule and costs. Since 2012 government supports the development of innovative software products using standards in order to improve quality. Quality improvement is affected by several factors, some contributing positively and others, negatively. The objective of this study is to identify which factors have influence on the practices adoption. The research method used is unique case study and a survey to collect complementary data. The studied company presented variations in the assessments results and during interviews, six most influential factors were identified. The company improved their software processes with the use of some practices in a project funded by government and lost some practices after that project. The factors that positively influences were: Experience in information technology and Top management support. The negative factors were: Competitive pressure, Perceived usefulness, Perceived ease of use and User training.

The peruvian component of Competisoft project: Lesson learned from academic perspective

The COMPETISOFT project in Peru represented an effort developed over three phases by students, professionals, teachers from universities and companies. They worked around to adopt a software process model called MoProSoft in small software development companies. Project implementation has generated different kind of results at the level of businesses, professionals and academics. This article shows the relevant aspects of the project, the work scheme followed, results and lessons learned from the academic perspective of a university-company relationship.

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.

Comparison of software process models. A systematic literature review

Nowadays, there are several software process models, which fulfill different purposes, approaches and requirements. However, this proliferation causes some confusion in the industry about the benefits or advantages of each proposal. In this context, studies have been conducted to determine the existing equivalence or the extent of coverage between these models having used different approaches to the comparisons. This work aims to present a study of techniques and experiences on comparison of software process models. For this study, a systematic literature review was conducted in relevant databases and available documents finding that there are few works or experiences in this area and it represents an aspect in software engineering the requires a higher level of research and development. Five different methods to compare process models were found and it was identified that the CCT - Comparison Composition Tree method is the unique that have a graphic representation.

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.

Impact of organizational and user factors on the acceptance and use of project management software in the medium-sized company in Lima

The use of software applications usually contributes most times the contexts where they are applied, however their adoption is not always effective. In particular, concerning project management, there are some difficulties in the context of medium-sized companies in Lima to use project management tools for the projects they manage. In this research our objective is to study the factors related to the organization and users for the acceptance of management tools. A survey was designed and performed based on a previous and similar study. A response was obtained from 77 managers of medium-sized projects with emphasis on the factors analyzed. Factors such as functionality, organizational size, project complexity and software use are the most representative. The study also found: (i) a strong and significant relationship between the use of software and the performance perception of the project manager and (ii) factors related to experience, training and education level have no effect.
