Question: Which type of corporate strategy deals with the industries or markets in which the firm competes through its products and business units? Is it cooperative, portfolio, functional or directional strategy? Unfortunately, my text does not provide any information on these strategies, but my assignment asks this question. I have searched the web for hours. I did locate some information on functional strategies, but I found very little regarding the other three. Please answer the question and provide a brief summary of each strategy or provide a website address where I may read about them.
