Vision

• Focus on Operational Strategies
• Measurable impacts
• Adaptation for Statewide deployment
• Work as a Statewide Team
• Engage Faculty from all campuses
• Take advantage of unique strengths/facilities
• Eliminate duplication
• Focus on delivery
• Work Closely with the Customer
• No Caltrans Ops Monitoring no Funding
• Academic Excellence
• Advance the State-of-the Art
• Maintain National Prominence
