SUN Cube: A New Stakeholder Management System for the Post-Merger Integration Process

Statistically more than 50% of all mergers do not achieve synergies. In majority of cases the reason is the failure in post-merger integration (PMI). This paper develops further how the Sun Cube framework can be used in capturing synergies during PMI. The SUN Cube is a new stakeholder management system that can be used in M&A and can be defined from four perspectives. One of the main achievements is the quantitative methodology suggesting top management and shareholders how assess readiness and possible effects on synergies in specific figures. The Sun Cube framework helps to focus on KPI of specific stakeholders. JEL Classification: G34
