The next step is to identify the key drivers and uncertainties that will shape the future scenarios. Drivers are the factors that influence or determine the direction and magnitude of change, such as technological, economic, social, environmental, or political trends. Uncertainties are the factors that are unpredictable or unknown, such as customer preferences, competitor actions, regulatory changes, or natural disasters. You can use various sources of information, such as data, research, expert opinions, or brainstorming, to identify the drivers and uncertainties that are most relevant and impactful for your analysis.
