Hipótese e Métricas: O Início do experimento
Antes de tudo, imagine que você gerencia uma loja na Shopee e percebe que muitos clientes devolvem roupas por causa do tamanho. Nossa hipótese central é: fornecer uma tabela de medidas detalhada e visualmente clara expandirá a satisfação do cliente e reduzirá as taxas de devolução. Para testar isso, precisamos definir métricas de sucesso. A principal será a taxa de devolução de roupas, mas também monitoraremos o tempo gasto na página de descrição do produto e o número de cliques na tabela de medidas.

O grupo de controle observará a descrição padrão do produto, sem a tabela de medidas aprimorada. Já o grupo experimental terá acesso à descrição com a nova tabela, destacada e simples de entender. Para garantir resultados confiáveis, o experimento durará 30 dias. Esse prazo permite coletar informações suficientes para identificar padrões significativos. Precisaremos de um designer para construir a tabela, um redator para otimizar a descrição e uma ferramenta de análise de informações para acompanhar as métricas.
O Grupo de Controle e a Tabela Mágica
Pense no grupo de controle como um rio que segue seu curso natural, sem interferências. Eles observarão as descrições de produtos exatamente como estão atualmente, sem qualquer alteração na apresentação das informações sobre tamanhos. O propósito aqui é ter um ponto de referência, um padrão com o qual comparar o desempenho do grupo experimental. É fundamental manter a consistência nesse grupo, garantindo que nada mude durante o período do experimento.
O grupo experimental, por outro lado, é como uma semente plantada em um solo fértil, recebendo um nutriente especial: a tabela de medidas detalhada. Essa tabela será cuidadosamente elaborada, com ilustrações claras e informações precisas sobre cada tamanho. A ideia é que os clientes do grupo experimental consigam encontrar o tamanho ideal com mais facilidade, reduzindo a incerteza e aumentando a confiança na compra. A tabela será um recurso visual atraente e simples de empregar, acessível diretamente na página do produto.
Análise de informações e Resultados Concretos
Após os 30 dias, os informações coletados se revelam como um mapa do tesouro. Analisaremos a taxa de devolução em ambos os grupos. Por exemplo, se a taxa de devolução no grupo de controle for de 10% e no grupo experimental for de 5%, o experimento demonstra uma redução significativa com a tabela de medidas. Além disso, observaremos o tempo gasto na página e os cliques na tabela. Um aumento no tempo gasto e nos cliques indica que os clientes estão utilizando e se beneficiando da tabela.
Outro exemplo: suponha que o grupo experimental tenha um aumento de 15% nas vendas de um determinado produto em comparação com o grupo de controle. Isso sugere que a tabela de medidas não apenas reduziu as devoluções, mas também impulsionou as vendas. Para executar esse experimento, precisamos de um designer (R$500), um redator (R$300) e uma ferramenta de análise (R$200/mês). O investimento total será de R$1000, com o propósito de expandir a satisfação do cliente e impulsionar as vendas.
