The long-term nature of decision-making: anticipating, choosing, evaluating
Effective decision-making requires not only models and data, but also the ability to assess impacts, risks and alignment with the organisational culture
Every decision contains a vision of the future. However, making a choice involves three distinct steps. The first is to anticipate: gathering information, interpreting it and formulating hypotheses about what might happen. The second is to decide: to weigh up alternatives and choose a course of action. The third, less obvious, is to evaluate the choice: its consequences, the sustainability of its impacts, and its consistency with priorities, culture and values – whether organisational or personal.
We tend to focus our attention primarily on the central section. In companies, we have often worked on decision-making models and techniques to ensure that the moment of choice is effective. However, I would like to shift the focus to what comes before and after it: even the best decision-making model is fragile if it is based on an approximate representation of the future, and no decision can be considered sound unless it is tested against the outcomes it may generate.
Predicting does not mean guessing. It means formulating hypotheses methodically, making their underlying assumptions explicit, and accepting that they may be revised or disproved.
With regard to this step, I have mainly used two approaches in the past. Forecasting estimates what might happen on the basis of data, trends and observable relationships, translating assumptions into explicit and updatable probabilities. Scenario planning, on the other hand, takes a different approach: rather than seeking a single, most probable future, it constructs different, plausible futures to assess how strategies and decisions might hold up under varying conditions.
The latter is a unique tool because it broadens our perspective, challenges established beliefs and reveals possibilities that a linear forecast might fail to capture. But it was precisely through working on scenarios that I developed a further realisation: a good representation of the future does not dictate the decision, nor does it exhaust the assessment of it.
