phuryn/pré-mortem

Execute uma análise de risco pré-mortem em um PRD ou plano de lançamento. Categoriza riscos como Tigres (problemas reais), Tigres de Papel (preocupações exageradas) e Elefantes (preocupações não ditas), em seguida classifica como bloqueador de lançamento, follow-up rápido ou monitoramento. Use ao se preparar para um lançamento, testar a resistência de um plano de produto ou identificar o que pode dar errado.

O que é pré-mortem?

Esta habilidade, phuryn/pre-mortem, conduz uma análise de risco pró-ativa chamada pré-mortem em Documentos de Requisitos de Produto (PRDs) ou planos de lançamento. Ela ajuda equipes a antecipar possíveis falhas antes que ocorram, categorizando os riscos identificados em três tipos distintos: Tigres (problemas genuínos que exigem ação imediata), Tigres de Papel (preocupações superdimensionadas que parecem maiores do que são) e Elefantes (problemas não discutidos abertamente, mas que podem ser críticos). Após a categorização, cada risco é classificado com base em seu impacto no cronograma como 'bloqueador de lançamento' (impede o lançamento), 'fast-follow' (deve ser resolvido logo após o lançamento) ou 'track' (monitorado, sem bloqueio). É particularmente útil para engenheiros, gerentes de produto e líderes de equipe que desejam validar a robustez de um plano antes de se comprometerem com uma data de lançamento. A habilidade funciona analisando o texto do plano fornecido e aplicando um framework estruturado de análise de riscos, similar ao modelo de pré-mortem popularizado na psicologia organizacional, mas adaptado para o contexto de desenvolvimento de software e lançamento de produtos.
