Product-market growth analysis would be most useful in determining where a firm will conduct business. This tool helps identify new markets for the firm to enter and whether to penetrate existing markets further. It considers factors such as market size, growth potential, competition, and the firm's strengths and weaknesses. The other options listed (experience curve matrix, SWOT analysis, and Porter's generic strategies) are useful in developing a comprehensive marketing strategy but do not specifically address the question of where to conduct business.
