Scenario planning is a foresight practice in which analysts build a small set of plausible futures and prepare an organisation for each. According to the arXiv abstract for 'Polyscene: Scenario Planning as Diversity Planning,' each scenario is a narrative that must be plausible, internally consistent, and relevant.
The paper introduces Polyscene, which reframes scenario planning as diversity planning. Rather than focusing only on the qualities of individual scenarios, this framing suggests that the set of scenarios should be chosen for its collective diversity — a shift from selecting futures that are merely coherent to selecting futures that are meaningfully different from one another.
The abstract is brief and does not detail the underlying method or evaluation. As a single source, it offers a conceptual proposal rather than an empirical comparison with existing scenario-planning approaches.
