n this course, we have studied the Porter's Competitive Forces Model. Explain comprehensively, offering some examples related to the Cambodian context, how information systems (IS) have and are changing each of the four components of the model, namely (1) new market entrants, (2) substitute products, (3) suppliers, and (4) customers. In the answer, you should explain how each of the four components have been transformed by the presence of information systems and technology (offering some examples and/or references to the Cambodian context) and give a comparison for each of these four components between the previous scenario (no-IS) and the current scenario (with IS). You can also focus on a specific case or company if it may facilitate the explanation. For instance, can start with mentioning how IS have changed the "new market entrants", offering some examples from the Cambodian context.
