另一个有助于评估索尼战略的战略工具是PEST分析。这是一个很有价值的工具，可以用来了解一个组织正在运作的环境的“大图景”(Bowman & Faulkner,1996)。PEST分析是一个将环境影响归类为政治、经济、社会和技术力量的框架(Jones & Hill 1992)。考虑到这一点，很重要的是要确定这些因素，因为它们可能会影响到索尼的供需水平和成本，尤其是在新兴市场。美国亚利桑那论文代写:索尼战略此外，PEST对索尼的战略有了最大的了解，因为它将显示出市场增长(新兴市场)和衰落(发达市场)，以及索尼业务的潜力和方向。更重要的是，PEST分析将显示出索尼的业务进入新市场和新国家是否值得。因此，SWOT和波特五力模型的PEST分析将有助于审查索尼的战略方向。
Another strategic tool that can help to evaluate Sony's strategy is PEST analysis. It is a valuable tool for understanding the 'big picture' of the environment in which an organisation is operating (Bowman & Faulkner, 1996). PEST analysis is a framework that categorises environmental influences as political, economic, social and technological forces (Jones & Hill 1992). In view of the fact it is important to identify those factors as they might have affect on Sony's supply and demand levels and its costs especially in emerging markets. Furthermore, PEST gives the greatest insight into Sony's strategy since it will show the market growth (emerging markets) and decline (developed markets), potential and direction for Sony's operations. What is more, PEST analysis will show whether it was worth to enter Sony's business operations into new markets and new countries. Consequently, PEST analysis with SWOT and Porter's Five Forces model will help to review Sony's strategic direction.
