The objective of any business organization is profit and sustainability. To attain this objective majority of business organizations follow a strategy to identify and encash all possible opportunities which include low-cost, product differentiation, high-tech products & services, international expansion, continuous value addition to products & services, and so on. As a result, many business organizations started in a given country, expanded their business to almost entire world and became global players. Such expansion strategy transformed them into multinational business firms having a number of subsidiaries or branches and through their huge structure, market share, and capability, and hence they became a prominent player in their industry/industry sector. Some of such firms further expanded their business to different industry and industry sectors and also started to use many business models to reach and cover the entire world. In this paper, we have discussed various business analysing frameworks used to analyse the business system and strategy used by many international firms and the environmental factors affecting their business. We have used ABCD listing methodology to identify the advantages, benefits, constraints, and disadvantages of these identified frameworks to analyse international business strategies and environmental analysis frameworks. Both criticism and suggestions on available framework usage are also given.
