The Corporate Strategy Interest Group considers the decisions, actions and outcomes associated with an organization's portfolio of business lines. The research and practice of corporate strategy considers actions associated with changing the firm's scope and profile of business lines including vertical integration, mergers and acquisitions, divestitures, corporate diversification strategy/organization, implementation and performance. Recent research considers how resources shape a firm's scope and relatedness of business lines, how firm resource composition influence merger and acquisition outcomes, how diversified firms are managed most effectively and why and when divestiture becomes viable. Other areas of interest include how a firm's resources impact upon its growth and divestment decisions, when different modes of growth and reduction are used, and what tradeoffs exist among various types of diversification strategy and its organization alternatives. Corporate strategy draws from a wide range of theories and methods to help explain the determinants and performance outcomes of managing the scope and boundaries of the diversified firm.
