Proposta por Nielsen análise Heurística é um método de engenharia de usabilidade para encontrar os erros de usabilidade em uma interface para que sejam corrigidos em um processo de desenvolvimento iterativo. Usa um grupo de avaliadores e tem como resultados compilados. Avaliadores devem ter conhecimento da aplicação, usuários e suas reações. </p> <p>Número de Avaliadores:</p> <p>N(i) = N (1-(1-p)i) </p> <p>Aonde i= número de avaliadores, N = nº de problemas e p = probabilidade de encontrar um problema com 1 único participante. Um único avaliador até 35% dos problemas. 5 avaliadores encontram 75% dos problemas. </p> <p>Examinar a interface separadamente percorrendo para ter noção do fluxo de navegação e focar em elementos específicos.</p> <p>Compilação, reunir os avaliadores e discutir os problemas e soluções. Importante lembrar que nenhum problema deve ser descartado. </p> <p>Severidade de cada problema: frequência (nº de vezes), impacto (impedimento de continuar) e persistência, tempo do usuário. Para cada tópico mencionado a cima usasse os níveis: 0 não concordo, 1 cosmético (não precisa ser corrigido), 2 baixa prioridade, 3 importante corrigir e 4 corrigir urgente.</p> <p>As heurísticas:</p>
