Lead end-to-end evaluation of actual buy-or-make cases, by evaluating actual costs, quality, supply logistics, and market conditions. Develop sophisticated economic models and sensitivity analyses to assess risk and uncertainty. Collaborate with cross-functional stakeholders to align strategies with actual outcomes. Lead the development and execution of backcast models, considering factors such as production efficiency, cost drivers, and market conditions. Conduct in-depth root cause analysis to identify factors influencing historical performance deviations. Collaborate with operational teams to implement corrective actions and continuous improvement initiatives. Assist in developing/verifying decision-making frameworks and communicate findings and recommendations to key stakeholders through clear and concise presentations. Integrate into the local refinery planning team and learn the tools and processes for completing deliverables and scheduling, including APS.
