Agile requirements validation in Brazilian software development companies: a survey
1 like76 views
The document presents a survey aimed at understanding how Brazilian software companies implement agile requirements validation, exploring techniques, stakeholder involvement, and challenges faced by teams. Key findings highlight the need for a broader understanding of requirements validation practices and the most commonly used artifacts. Limitations include a limited number of respondents and uneven geographic representation, suggesting future research directions to obtain a more comprehensive dataset.
