Michael Porter - Estratégia Competitiva


Qual a teoria de Michael Porter?  Estratégia Competitiva.  

As 5 forças de Porter são: 

1) ameaça de produtos substitutos; 
2) ameaça de entrada de novos concorrentes; 
3) poder de negociação dos clientes; 
4) poder de negociação dos fornecedores  
5) rivalidade entre os concorrentes. 
São os pilares de uma empresa, e se algum mudar, deve-se reavaliar seu posicionamento estratégico

Do seu trabalho resultaram conceitos de estratégia que marcaram a disciplina como a análise de indústrias em torno de cinco forças competitivas; e as duas fontes genéricas de vantagem competitiva: diferenciação e baixo custo

Windows 11 em Dell

 Quando o Microsoft Windows 11 foi lançado, as atualização automáticas do Microsoft Windows 10 deu como resultado do diagnóstico automático de hardware que o Windows 11 não podia ser instalado no meu notebook Dell Inspiron com processador Intel de 7a. geração. E durante vários meses eu tentei instalar o Windows 11 no notebook Dell e sempre aparecia a tela dizendo que não pode instalar.

Em Julho/2022 eu li um artigo na internet falando que o UEFI tem que estar ativo funcionando para o Windows 11 poder ser instalado; então eu olhei o setup do meu notebook Dell, no item em segurança eu vi que o UEFI aparecia como desligado, então eu desativei o item Legacy, e ativei o UEFI, e gravei a alteração do Setup do notebook Dell.

Então eu peguei um disco rígido USB de 1TB e fiz o backup 100% de todos os arquivos que eu utilizo, que estavam dentro do disco rígido 1tb do meu notebook Dell. Como o disco rígido do notebook Dell não é SSD, esse backup demorou uma semana para concluir.

Depois do backup USB pronto, eu copiei o Windows 11 para dentro de um pendrive USB 8gb, e mandei o Windows 11 começar a instalação, como eu gosto de fazer instalação limpa, mandei o Windows 11 excluir a partição do disco rígido, depois mandei o Windows 11 criar uma partição nova no disco rígido, e depois mandei o Windows 11 formatar o disco rígido, e assim começou a instalação do Windows 11.

Depois disso, eu notei que fazer a instalação do Windows 11 utilizando a rede wireless é muito lerdo, iria demorar muitas horas para a instalação concluir, então para o download e instalação ficar rápido, eu liguei direto um cabo ethernet do meu roteador wireless até o notebook Dell.

Em Julho/2022 eu consegui fazer a instalação do Windows 11 Home Single Language funcionar em um notebook Dell com processador Intel de 7a geração. Eu estou gostando muito de usar o windows 11.
