  • #5: Como escalar agilidade ¨¦ a nova pergunta SAFe ¨C Algumas pr¨¢ticas ¡®prescritivas¡¯, adapt¨¢vel, alinhamento entre os diversos n¨ªveis DAD ¨C goal-driven, foco em arquitetura, divis?o por fases Kanban ¨C evolu??o incremental, baseado em m¨¦tricas acion¨¢veis Mais importante do que qual framework ¨¦ como ser¨¢ feita a transforma??o (exemplo do RUP, medo de falar de RUP em conferencias de agile)
  • #6: Um outro impedimento para a escalabilidade Vira custo de propriedade Fica escondido nos prazos, custos e qualidade esperada ? preciso visualizar o DT para atac¨¢-lo (assim como tudo=princ¨ªpio ¨¢gil)
  • #7: Se o DT n?o for identificado e combatido, nenhuma implanta??o ¨¢gil escala
  • #8: Tecnologias antigas, propriet¨¢rias e fechadas acabam virando DT O custo do d¨¦bito t¨¦cnico normalmente fica escondido, disfar?ado como custo normal de opera??o, embutido nas estimativas, prazos e desculpas

  • #17: Statistics: We have a fairly large deployment. We are definitely enterprise level in terms of numbers of users, and a moderately large sized data envrionment. Deployment Characteristics: We have one team administering our entire deployment of RQM (and all jazz based products). All our RQM servers are hosted in one location. The teams that use the deployment are globally distributed and we have a true WAN experience. We are constantly upgrading our OS, application server, and DB. We also even switch platforms to broaden our understanding of customer experience. For example, we went form AIX to Redhat for the application server. We went from a physical to a virtualized environment.
