PETRONAS Carigali Sdn Bhd has embarked on a journey to incorporate Integrated Operations (IO) concepts as a standard way of working across their production business. Early on it was identified that the implementation of IO as a core enabling element within the production business would create a fundamental change in operations -transforming decision-making from a mechanical process to an organic capability by embedding a culture of collaboration as the basis of an asset's Operations Philosophy (i.e. an asset mindset operating within a functional organization). This fundamental change would require visible leadership in addition to the management of incremental implementation steps: a combined top-down, bottom-up approach.Further, there would be long term structural transformation due to: scale (the change affects multiple assets not only individually but also collectively with significant implications to the rest of the organization), magnitude (it will involve significant alterations to information availability, capability, and decision-making processes), duration (implementation will span a number of years), and strategic importance to PETRONAS' future business.Consequently, a comprehensive IO business transformation strategy was required, based on an in-depth understanding of what the implications of the various asset-level digital field solutions are for the organization as a whole, as well as individual stakeholders, driving a plan customized to optimally lead the adoption effort through tailored interventions by business unit, location, role, function, and decisionmaking patterns. This paper will review the specific implications of IO within the organization and present how a business transformation strategy was developed to optimally manage the consequences, while mitigating the risks to success. Executive SummaryThe following statements form the basis of the IO transformation strategy and implementation plan:1. Implementation of IO will create a fundamental change in operations by: a.
