Reaching a New Frontier Leadership, Planning and Management
TraditionalLeadershipDictates direction
PlanningPartitioned by disciplines and is linear. Predictive and generally fixed, setting parameters for management
ManagementControls are inflexible, autocratic -processes are fixed and measures are isolated and historical
Lean Facilitates collaborative direction
Collaborative, project based and seeks to integrate efforts to eliminate negative iterations. Learns as project evolves
Develops a “network of commitments” to implement plan, evolves intelligence, measures are integrated and proactive

Lean Principles
− Collaborate – really collaborate
− Early engagement of team members
− Target Value Design
− Last Planner – all parties involved in the schedule
− Elimination of waste and duplicate activities
− Implement the 5 S’s
− Continuous feedback and learning

Follow the 5 S’s

Integrated Project Delivery (IPD)
− Integrates people, systems, business structures and practices into a process that collaboratively harnesses the talents and insights of all participants to reduce waste and optimize efficiency through all phases of design, fabrication and construction.
− IPD is the process;BIM and Last Plannerare the collaborative tools

Value to User Groups
− Cost Avoidance
− Open Doors to Facility Faster
− User Input, Review and Approvals− Fewer changes
− Fewer Inconveniences− Minimal disruption to ongoing operations− Less Manpower i.e. decrease in parking needed, safety
issues, etc.
− Collaborative Team Effort
