Improving Corporate Governance Mechanisms by Enhancing the Effectiveness of the Supervisory Board

This article systematizes theoretical approaches to evaluating supervisory board performance and proposes a conceptual diagnostic framework. Five assessment dimensions are distinguished: independence and competencies, strategic oversight, risk control, transparency, and decision outcomes. The paper specifies indicators, normalization and aggregation procedures, and a management response algorithm. A numerical example uses hypothetical data and is not presented as empirical validation. The framework is intended for adaptation by joint-stock companies in Uzbekistan, subject to sector-specific calibration and further empirical testing.
