Melhoria de processo de software: Conhecimento, utilização e benefícios em empresas canadenses de desenvolvimento de software

Desde 1982, a comunidade de desenvolvimento de software tem estado preocupada com a entrega de sistemas com qualidade. A melhoria de processo de software (MPS) é uma iniciativa que visa a evitar a entrega de sistemas de baixa qualidade. Entretanto, o conhecimento e a adoção da MPS são baixos. Assim, este estudo examina o nível de conhecimento, utilização e benefícios de iniciativas de MPS em empresas canadenses de desenvolvimento de software. Utilizando o SPSS como ferramenta analítica, este estudo descobriu que 59% das empresas canadenses de desenvolvimento de software conhecem programas de MPS, e 43% dos funcionários utilizam alguma forma de programa de MPS para desenvolver produtos de software. Embora o tamanho da amostra seja pequeno e os resultados não possam ser generalizados, as firmas estudadas que utilizam programas de MPS relataram uma melhoria na qualidade dos produtos de software como sendo o maior benefício. Estas conclusões confirmam a importância dos programas de MPS como modo de produzir produtos de software de qualidade mais elevada, o que pode aumentar a probabilidade das empresas de software de conquistar contratos globais

Investigating the relationship between software process improvement, situational change, and business success in software SMEs

While we have learned a great deal from Software Process Improvement (SPI) research to date, no earlier study has been designed from the outset to examine the relationship between SPI and business success in software development small- to- medium- sized companies (software SMEs). Since business processes are generally acknowledged as having an important role to play in supporting business success, it follows that the software development process (a large and complex component of the overall business process) has an important contribution to make in supporting business success in software development companies. However, to date we have very little evidence regarding the role of SPI in supporting business success, especially for software SMEs. The need for SPI is dependent on the extent of situational change in a software development setting, and therefore any examination of the relationship between SPI and business success would be deficient if it did not also examine the extent of situational change. Therefore, this thesis describes a novel approach to examining SPI, situational change and business success in software development companies. Furthermore, having discharged this new approach to 15 software SMEs, this thesis makes the important new discovery that the amount of SPI implemented in a software SME is positively associated with the extent of business success – especially when the degree of situational change is taken into account. This thesis describes the first published study to examine the relationship between SPI, situational change and business success in software SMEs. The findings suggest that there are business benefits to implementing SPI in software SMEs, with the degree of situational change being an important factor informing SPI initiatives. Furthermore, this research has yielded valuable new insights into the nature of SPI, situational change and business success in software SMEs
