I'm taking a class on Multinational Management, specifically using the textbook "Multinational Management: A Strategic Approach" (7th edition) by Cullen & Parboteeah. I need help understanding the following concepts:

1. How are resources, capabilities, distinctive competencies, and eventual profitability interconnected in a multinational firm?
2. What are key success factors (KSFs), and why are they crucial for multinationals? Could you describe their individual characteristics?
3. What is competitor analysis, and why is it significant for the success of multinational companies? What are the steps involved in conducting competitor analysis?
4. What is a company-situation analysis, such as SWOT, and why is each step important?

Could you please provide detailed explanations for each of these points? Thank you!
