Few organisations can ignore the opportunities offered by mergers or acquisitions. While everyone focuses on pre-deal financial structuring and due diligence, less attention is given to post-deal integration. And our recent Barometer on Change research identified that only 29% of organisations realise their anticipated benefits. To achieve the intended benefits of a transaction, it is important to dedicate time and resources to integrating the businesses successfully. This requires approaching the integration with a clear scope, sound business case and well-controlled programme of delivery.
