analysis-of-interconnected-decision-areas-aida

The chapter elaborates on the strategic choice approach by detailing the construction and interpretation of decision graphs to manage complex decision areas and their interconnections. It introduces the Analysis of Interconnected Decision Areas (AIDA) method, which systematically explores feasible combinations of mutually exclusive options constrained by incompatibilities known as option bars, using tools like option bar matrices and option trees to logically eliminate infeasible alternatives. The chapter emphasizes generating a rich yet manageable set of alternatives within a selected problem focus rather than seeking a single optimum solution.

The chapter presents a detailed case study of applying the strategic choice approach to national LPG policy formulation in The Netherlands following a major accident, highlighting the complexity, uncertainty, and conflict that stalled decision-making. It describes the transition from a hard systems framework to a decision-centred approach, prioritizing decision areas using criteria like urgency and controllability, and employing the Analysis of Interconnected Decision Areas (AIDA) to clarify complex clusters. The chapter further explores the iterative process of designing and comparing transportation policy options, emphasizing challenges in option representation, the necessity of deferring some decisions to operational levels, and the value of learning by doing in refining strategic choices amid uncertainty and conflict.
