Increasing Yield ProfitabilityPerformance Management ImprovementPerformance Management Improvement
• Example of diesel yield improvementso Analyzing homogeneous data related to “sweet” crudes:o Analyzing homogeneous data related to sweet crudes:
• 2003 actual average diesel yield 37,4%
• 2004 actual average diesel yield 39,6%
l d l ld d d b ho Average actual diesel yield increased due both to investments on plants and to performance management.
o Historical analysis on diesel yield showed that the average increase d f b hdue to performance management amount was about 0.8% in the period 2003‐2004.
o This led to a profit increase estimated in US$ 1 million per year.
