This article presents object orientation concepts that allow the reader to develop code with improved quality aiming reuse, less defects, simpler designs and better responsibility segregation. To achieve this, fundamental concepts of object orientation interpretations are presented that serve as the foundation to a deeper understanding of design concepts that drive the development of more robust applications.

An interview about whether the design of the software should be planned ahead or evolved along, as the software itself is developed.

Although small- and medium-sized enterprises (SMEs) represent most of the of Brazilian software industry, these organizations struggle to implement software process improvement (SPI) initiatives aiming to increase their competitive advantages. One cause of the failure of many SPI initiatives conducted by SMEs is the lack of adequate process implementation approaches aligned to common characteristics of SMEs, such as a lack of financial and human resources.

Although small- and medium-sized enterprises (SMEs) represent most of the of Brazilian software industry, these organizations struggle to implement software process improvement (SPI) initiatives aiming to increase their competitive advantages. One cause of the failure of many SPI initiatives conducted by SMEs is the lack of adequate process implementation approaches aligned to common characteristics of SMEs, such as a lack of financial and human resources. During the last five years, the Brazilian software industry and research universities have been working cooperatively to develop and disseminate a Brazilian software process model, the MPS model, aimed at improving the quality of Brazilian software processes and products. To cope with the difficulties SMEs face during SPI implementation and to facilitate the dissemination of the MPS model, the authors developed an approach called SPI-KM, supported by a process-centered software engineering environment known as the Taba Workstation. The MPS model and the Taba Workstation are presented in this article. The results and lessons learned from the application of the SPI-KM approach in a group of five Brazilian SMEs that implemented the MPS model are also described. Show less

Appropriate process implementation approaches are fundamental for small and medium-size enterprises (SMEs) to obtain the most of software process improvement (SPI) benefits. COPPE/UFRJ has been providing SPI consultancy services to the Brazilian software industry for more than two decades. In order to cope with factors that have influence on SPI success, we developed an approach to implement SPI initiatives based on the Brazilian software process model (named MPS model) through the adoption of a SPI strategy (named SPI-KM) and the support of a process-centered software engineering environment named Taba Workstation. This paper presents the work conducted in a group of Brazilian SMEs aiming to deploy the MPS model based initiatives using the SPI-KM strategy supported by the Taba Workstation. We also discuss the lessons learned from implementing SPI in this group of SMEs and also other lessons collected throughout previous SPI experiences. Show less

Statistical process control has been used in order to control the performance of software processes. Howerver, this technique is limited to control the value of a metric in a current project, compared to the same metric considering the process performance. In this paper we present a quantitative project management methodology combining statistical process control and statistical performance models to allow predicting behaviors for differente scenarios to support managerial decisions.

International software standards and maturity models play an important role in Software Process Improvement initiatives defining best practices and providing knowledge to the definition of software processes. Nevertheless, the definition and deployment of software processes based on that standards and models is an expensive and knowledge intensive task. This paper describes an approach to the definition and deployment of software processes in small and medium size Brazilian companies supported by a Process-centered Software Engineering Environment named Taba Workstation. It also presents results related to a software process improvement initiative undertaken in a Brazilian organization that demonstrates the feasibility of the presented approach. Show less

Deployment of software processes based on reference models is a knowledge-intensive task, i.e., a great amount of technical knowledge must be applied in order to guarantee conformance and adherence of processes deployed to the reference models adopted. Moreover, software process deployers have to deal with organizational and individual cultural problems on a regular basis, for instance, resistances to organizational changes. Therefore, the success of software process deployment within an… Show more

Deployment of software processes based on reference models is a knowledge-intensive task, i.e., a great amount of technical knowledge must be applied in order to guarantee conformance and adherence of processes deployed to the reference models adopted. Moreover, software process deployers have to deal with organizational and individual cultural problems on a regular basis, for instance, resistances to organizational changes. Therefore, the success of software process deployment within an organization or organizational unit depends on both technical and social aspects of the software process deployment strategy definition and execution. This paper presents the Taba Workstation, an enterprise-oriented Process-centered Software Engineering Environment (PSEE) constituted of an integrated set of tools to support software process deployment based on the Capability Maturity Model Integration (CMMI) and the Reference Model for Brazilian Software Process Improvement (MR-MPS.BR). Software process appraisals demonstrated that the Taba Workstation constitutes one of the most important organizational assets to facilitate the success of software process deployment initiatives and to overcome the inherent difficulties.

The definition of software processes based on national or international reference models is important, but not sufficient to guarantee the quality of software products and processes. In order to increase the efficacy and efficiency of those processes and to increase the quality of software products, it is fundamental to guarantee the adequate execution of software processes. This work presents an approach to guarantee software processes quality with the support of Knowledge Management in the… Show more

The construction of any knowledge representation and reasoning system begins with an unambiguous representation language which allows representing knowledge about a specific domain through a set of sentences. This set of sentences is called knowledge base. Besides that, well defined means of manipulating these bases are needed in both construction and utilization.
