Contextual factors affecting the integration of enterprise systems in post-merger oil and gas companies

Abstract
This study examines the contextual factors of the external business environment, organization, information systems, and enterprise system software as they affect integration of enterprise resource planning (ERP) systems after a merger or acquisition in the oil and gas industry. A multiple case study method using primary and secondary data revealed: ERPs are operational necessities rather than strategic differentiators; best practice adoption is a viable alternative that supports successful integration of cultures and knowledge from two experienced organizations; schedules are extended when best practices from both companies are consolidated into a single instance; consolidation facilitates Sarbanes-Oxley compliance and lowers the cost of ownership; imposing acquirer systems on targets facilitates timely decision-making and shorter schedules.
