2. Project Scope: Decrease cycle time from Arrival to RME
Doctor (ESI 3-5)
• Project selection approach
1. Identified four potential projects
2. Gathered time stamp data for each potential project
3. Used benchmarks and waste walk to determine
performance gaps
4. Selected this project based on the highest score on the
project selection matrix
• Project targets
▫ Performance gap (1-5): 4 – validated by lean measures
▫ Current median time: 1 hr. and 34 minutes
▫ Goal median time: 37 minutes – based on benchmark
▫ GOAL Median Time BASED ON LEAN SIX
SIGMA MEASURE - 18 minutes
No Wait time in between steps
No sitting down or back and forth
Taking only the value added time with at least
80% efficiency rate.
Current performance gap
(1= gap is small; 5= large gap with ideal performance)
4
Cost to business if NO changes made
(1= low cost; 5=high cost)
4
Impact on customer satisfaction
(1= low impact; 5= high impact)
4
Degree of waste
(1= little or no waste; 5= lots of waste)
4
Customers can be defined
(1= not easily defined; 5=easily to define)
4
Inputs can be identified
(1= hard to identify; 5easy to identify)
4
Outputs can be identified
(1= hard to identify; 5easy to identify)
5
Data is available
(1= difficult to collect or manual; 5easy to obtain,
electronic)
5
Team needed to understand / identify solutions
(1= team NOT needed; 5= team definitely needed)
4
Team has authority to implement solutions
(1= little or no authority; 5= has authority to implement)
4
Manageable project scope
(1= very large scope; 5= contained, narrow scope)

Current Metrics
• Total cycle time: 1 hr 34 mins
• Value added time: 13 mins
• Non-value added time: 1 hr 21 mins
• Process cycle efficiency: 13.82%
Key Definitions
• Process cycle efficiency (PCE): the
percentage of value-add time divided by total
time (cycle time)
• Value added time: time associated with work
that is desired by the customer
• Non-value added time: time related to work
not beneficial to customer – by lean standards is
waste in a process

Proposed Metrics- Benchmark
Total cycle time: 37 mins
• Value added time: 18 mins
• Non-value added time: 19 mins
Process cycle efficiency: 48.65%
Proposed Metrics- Ideal – Lean SS Standard
Total cycle time: 18 min
• Value added time: 13 mins
• Non-value added time: 0 to 5 min
Process cycle efficiency: 80% to 100%
Key Proposed Changes
• Patients are pushed to the next step rather than
pulled from the waiting room
• Registration should be a parallel process with the
clinical assessment
• The RME MD/NP does not waste time looking for
the next patient
• Limit microphone usage and time wasted finding
patients/rooms
• Eliminate time wasted for RME orders due to no
quick registration
4 minutes
Key Highlights
8. NEXT STEPS
• Analyze the detailed Process Flow (approx 60 steps) with PFS Co-participant, committee and
stakeholders to eliminate waste in the process and implement parallel functions
• Conduct Kaizen events to implement phased changes
Phase I – Registration with clinical functions
Phase II – Physical re-configuration of patient flow
Phase III- Eliminating all the wasted steps in the process
