26. CONCLUSIONS
➤ We contributed to enhance the understanding about how Brazilian practitioners carry
out requirements validation activities in their agile projects;
➤ Understand who are the stakeholders that usually attend to requirements validation;
➤ Analyse the problems faced by the teams;
➤ List what are the most popular artefacts applied to Agile RE.

27. LIMITATIONS
➤ The results are reasonable but still limited number of respondents;
➤ The results are not equally distributed in all Brazilian regions;
➤ The majority of respondents are from private companies.

28. FUTURE WORK
➤ Replicated the survey to reach a broad and representative population;
➤ Balance the number of participants from all the regions of Brazil;
➤ Invite more people from public organisations
