The results of the GE Nine Cell Matrix analysis show a diverse position for the company's business units, with some as "Leaders" and others needing to be managed carefully or even divested. The managerial implications of this study are the need for business ecosystem development and business portfolio diversification, technology development across businesses to support competitive advantage, and the creation of new opportunities after the completion of the Trans-Sumatra Toll Road project]]>
