摘要：Atualmente softwares têm sido reconhecidos como importante ferramenta de apoio às diversas atividades e à tomada de decisões. No entanto, existem relatos a respeito de projetos de desenvolvimento de software fracassados. A questão problema apresentada por este artigo é a seguinte: Como é possível realizar a avaliação da qualidade de um produto de software desde as etapas iniciais do projeto, de forma que seja possível realizar as melhorias com menor esforço? O artigo traz uma abordagem metodológica para a priorização dos requisitos de software e a avaliação da qualidade do produto de software, segundo a percepção dos usuários. Em especial, a abordagem propõe o emprego da Análise Importância-Desempenho (IPA) e do método dos 100 pontos para a etapa de priorização, e para a etapa de avaliação de desempenho, o emprego da IPA e da escala contínua. Por meio de estudo de caso, a abordagem proposta foi aplicada a um projeto de desenvolvimento de software para gestão de recursos humanos. A partir desse uso foi possível captar os julgamentos, determinar as prioridades dos requisitos conforme a percepção dos usuários e sugerir ações relevantes com o objetivo de melhorar a qualidade do software. Acredita-se que a abordagem proposta seja aplicável ao desenvolvimento de produtos de software de pequeno porte. Palavras-chave Priorização de requisitos. Qualidade de software. Produto de software. Prioritizaion of requirements and evaluation of software quality according to the users' perspective Abstract Nowadays software has been recognized as an important tool to support various activities and decision making. However, there are several reports regarding failures on development of software projects. In this scenario, the phase of requirements elicitation, allied to users’ satisfaction, has been highlighted as leading to the improvement of the software development process. Thus, the main issue presented by this article is defined as follows: How is it possible to assess the quality of software product from the initial stages of design, so we can make improvements with less effort? This article proposes a methodological approach for prioritizing software requirements and evaluating the quality of software products according to the users’ perspective. In particular, such approach proposes the use of Importance-Performance Analysis (IPA) and the 100-points method for prioritizing the requirements, and the use of IPA and the continuous scale for doing the performance evaluation stage. By conducting a case study, the proposed approach was applied to a software development project for human resource management. By doing so, users’ evaluations were collected, the software requirements were prioritized according to their perspectives and relevant actions were suggested in order to improve the quality of the software.

important tool to support various activities and decision
making. However, there are several reports regarding
failures on development of software projects. In this
scenario, the phase of requirements elicitation, allied
to users’ satisfaction, has been highlighted as leading
to the improvement of the software development
process. Thus, the main issue presented by this article
is defined as follows: How is it possible to assess the
quality of software product from the initial stages of
design, so we can make improvements with less effort?
This article proposes a methodological approach for
prioritizing software requirements and evaluating the
quality of software products according to the users’
perspective. In particular, such approach proposes the
use of Importance-Performance Analysis (IPA) and the
100-points method for prioritizing the requirements, and
the use of IPA and the continuous scale for doing the
performance evaluation stage. By conducting a case
study, the proposed approach was applied to a software
development project for human resource management.
By doing so, users’ evaluations were collected, the
software requirements were prioritized according to their
perspectives and relevant actions were suggested in
order to improve the quality of the software. It is believed
that the proposed approach may be suitable to the
development of small software products.
