Selected DMAIC Project Overviews
Created a common platform by which all sites can track how they accommodate requests for non-network services. This approach for allows for increased service levels to members looking for accommodations, while also providing valuable input into the network development process.
Accommodation Standardization
Improved the entire process around member communications. Order accuracy was addressed by implementing guidelines that coincided with a streamlined process, while the internal costs associated with handling the materials were reduced through the addition of bar-coding procedures.
Member Communication Costs
Standardized the process by which nurses make outbound calls to members to follow-up on treatment recommendations and care delivery. Moved all assessments to an on-line format, allowing for improved reporting and a consistency in both the questions asked and the documented assessments. This resulted in increased quality and the opportunity for each nurse to reach more members per day.
On-line Clinical Assessments
Along with developing a standard operating procedure for the transplant referral process, associated tools were implemented specific to each component to help staff more easily identify referral opportunities. More members will now benefit from transplant clinical consulting services and access to the nation’s leading transplant programs through United Resource Networks’ Transplant Resource Services Centers of Excellence Network.

What is “Standardization”?
A consistent method of achieving efficient productionwithout waste , based on human action.
• Highest quality, most efficient, safest way you know today
• Only one standard at a time
• Documentation of know-how
• Objective, simple, observable
• Consistent with quality, cost, regulatory and customer delivery requirements
• Show relationship between cause and effect

Standardization vs. Defect Reduction
Standardization
Improving productivity and quality by standardizing all human actions associated with a single process. Provides the foundation for further process improvement and defect reduction.
Defect Reduction
Reducing the defects of a single Critical-to-Quality characteristic by focusing on the key input variables of a process.

“A philosophy of continuous improvement based on setting standards aimed at eliminating
waste through participation of all employees.”
What is “Lean?”
The goal of Lean is to accelerate the velocity of any process by reducing waste.

Comprised of the Japanese words meaning “change” and “better”
A Kaizen Event is a 3 day workshop focused on rapid improvement
through the observation and analysis of a process. Process performers
learn and use Lean concepts to remove waste, reduce variability,
standardize work, and implement the improved process as the new
standard.

The Eight Deadly Wastes
• Motion / Walking
• Processing
• Correction
• Waiting
• Overproduction / Early Production
• Conveyance
• Inventory
• Not Utilizing the Talent and Knowledge of People

Similarities Between Six Sigma and Lean
• Employ DMAIC methodology
• Utilize tools for process characterization and optimization
• Rely on cultural change
• Focus on variation and waste
• Approach making decisions on business processes in a structured way
