This study draws on information processing theory to investigate predictors of strategic-decision quality in public organizations. Information processing theory argues that (a) rational planning practices contribute to strategic-decision quality by injecting information into decision making and (b) decision makers contribute to strategic-decision quality by exchanging information during decision making. These assumptions are tested upon 55 Flemish pupil guidance centers. Rational planning practices are operationalized as strategic planning, performance measurement, and performance management. Information exchange by decision makers during decision making is operationalized as procedural justice of the decision-making process. Results suggest that procedural justice, strategic planning, and performance management contribute to strategic-decision quality while performance measurement does not.
