ANÁLISE DAS 5 FORÇAS DE PORTER

Introdução Michael E. Porter é uma figura essencial do Marketing Estratégico. Autor de quase duas dezenas de livros e artigos, sobretudo nas áreas da Estratégia e da Competividade. As Cinco forças de Porter são pela primeira vez mencionadas e estruturadas no seu artigo “How competitive forces shape strategy” para o Harvard Business Review na edição de Março-Abril, onde em dez páginas esboça os princípios do que define como as cinco forças da competitividade. A análise SWOT (Strengths, Weaknesses, Opportunities & Threats) é outro importante componente da estratégia do Marketing Estratégico, sendo divergente a opinião da origem deste acrónimo. Ele encontra-se geralmente associado ao professor da Universidade de Standford Albert Humphrey no entando não é fidedigno afirmar que este será o autor deste método de análise. Com base na proposta do Professor João Rosário elaboramos um trabalho de pesquisa avançada na tentativa de enunciar uma síntese directa e inequívoca sobre este tema. No que toca ás Cinco forças de Porter recorremos ás publicações da Harvard Business Review e ás suas publicações literárias na tentativa de compreender a metamorfose informativa e evolutiva que este tópico poderá ter sofrido das suas publicações de 1979 para as publicações contemporâneas. Tentámos depois comparar com a análise SWOT com base em livros de especialidade relativos a esse assunto (mencionados na Biografia).

As Cinco forças de Porter Um planeamento estratégico é essencial para a superioridade perante a concorrência mas não são só as empresas que nos são concorrentes que estabelecem as dificuldades da nossa. Porter define que essa é apenas uma das cinco forças que poderão causar dificuldades ou impulsionar um negócio, sendo mais extensivo que apenas a força da rivalidade dos clientes, inserindo também então quatro outras forças: Potenciais novos concorrentes, poder de negociação dos

    1. SWOT analysis is a marketing strategy used to find a company’s strengths and opportunities for a manager to take full advantage of them. The other two words are in the acronym are weaknesses and threats which the manager will try to work around or improve. This is needed for a company to make a marketing strategy and to become better than the competition. For example, if two companies both sold movies and they were pretty much the same in everything they do, people would go to either. But if one of those companies did a SWOT analysis and found that they can make finding these movies in the store a lot easier, then maybe they can attract more customers to their store. This would be seizing more opportunities and adding to their strengths. (pg. 49)…

    The rivalry among competing sellers. The most powerful of the five competitive forces is usually the competitive battle among rival firms. How vigorously sellers use the competitive weapons at their disposal to jockey for a stronger market position and win a competitive edge over rivals shows the strength of this competitive force. Competitive strategy is the narrower portion of business strategy dealing with a company 's competitive approaches for achieving market success, its offensive moves to secure a competitive edge over rival firms, and its defensive moves to protect its competitive position. As noted by Fleisher and Bensoussan (2003), Porter’s fifth force, competitive rivalry, is also an element addressed by the strategic group analysis where it considers competitive rivalry and how this force both impact and it is impacted by other four forces. Porter (1980, taken from Bowman, 1998) suggests that the level of rivalry, the actual competition between existing producers, varies according to a number of factors.…
