                <p>Este estudo investiga como técnicas de machine learning não supervisionado podem
                    apoiar People Analytics em organizações públicas brasileiras, contexto marcado
                    por baixa maturidade analítica. Utilizando dados anonimizados de empregados
                    ativos da ApexBrasil entre janeiro de 2019 e dezembro de 2023, o trabalho segue
                    o framework CRISP-DM para comparar três métodos de clusterização: K-means,
                    Clustering Hierárquico e DBSCAN. Embora o DBSCAN tenha apresentado maiores
                    índices de silhueta, ele classificou grande parte dos registros como ruído,
                    limitando sua utilidade organizacional. Assim, o K-means com oito grupos foi
                    selecionado como melhor equilíbrio entre qualidade técnica e cobertura amostral.
                    Os agrupamentos resultantes foram interpretados como perfis distintos de força
                    de trabalho, fornecendo uma base interpretável para investigações futuras sobre
                    perfis de força de trabalho em organizações públicas. Os resultados demonstram a
                    viabilidade de implementação de People Analytics em contextos de dados
                    administrativos limitados, oferecendo framework replicável para organizações
                    públicas similares.</p>

                <title>ABSTRACT</title>
                <p>This study investigates how unsupervised machine learning techniques can support
                    People Analytics in Brazilian public organizations, a context characterized by
                    low analytical maturity. Using anonymized data from ApexBrasil’s active
                    employees between January 2019 and December 2023, the work follows the CRISP-DM
                    framework to compare three clustering methods: K-means, Hierarchical Clustering,
                    and DBSCAN. Although DBSCAN presented higher silhouette indices, it classified a
                    large portion of records as noise, limiting its organizational utility. Thus,
                    K-means with eight clusters was selected as the best balance between technical
                    quality and sample coverage. The resulting clusters were interpreted as distinct
                    workforce profiles, providing an interpretable basis for future People Analytics
                    investigations and workforce heterogeneity assessment. The results demonstrate
                    the feasibility of implementing People Analytics in contexts with limited
                    administrative data, offering a replicable framework for similar public
                    organizations.</p>
