McDonald's is facing issues from foreign currency fluctuations that are deteriorating their service and causing problems globally. Weak economic circumstances are requiring additional investments to remain profitable and competitive in markets, but incurring high costs. Determining the appropriate investment levels to inject into different markets may impact profitability. While McDonald's has strengths like quality control and human resources, it is seen by some as promoting junk food. Opportunities exist in offering more variety and innovative products in their growing number of global outlets. However, changing consumer trends toward healthier eating and regulatory agencies focusing on health impacts of junk food present threats.
