“…Diversos autores defendem uma composição ideal quanto à execução do Delphi entre duas a quatro rodadas, porém não descartam um número inferior desde que se consiga um nível satisfatório de consenso nas respostas (Nworie, 2011). Os passos da pesquisa, explicitados a seguir, levaram em consideração os direcionamentos de Giovinazzo e Fischmann (2011) (2015)] e no contexto investigativo, abordando questões de ordem prática previamente identificadas e discutidas pelos autores junto a especialistas; (c) definição do perfil e seleção dos painelistas (neste caso, utilizando-se os critérios de formação, experiência profissional e disponibilidade para participação na pesquisa); (d) 1ª rodada do painel, com a coleta de dados via internet; (e) tabulação e análise das respostas coletadas via internet; (f) envio da síntese das respostas aos painelistas; (g) 2ª rodada do painel com coleta de dados via internet; (h) verificação e análise da convergência das respostas; (i) relatório final.…”

“…Foram realizadas duas rodadas de consulta junto a 29 painelistas na primeira rodada e 21 na segunda. O número de especialistas se aproxima daquele recomendado por Brockhoff (1975) e Nworie (2011), isto é, entre 10 e 18.…”
