2. What is Lean?
• Management Method • Design Method
– Best patient care – Patient/family-focused
– Engaging staff – Engaging staff
– Minimizing waste – Minimize waste
• Eliminating barriers – Right size / resources
– Fit your processes
– Continuous improvement – Iterative improvement of a
• Better quality at a lower one-time design innovation
cost • Better meets needs at a
lower cost, with fewer
delays

5. “Lean Construction”
• “Lean construction is a new way to design and build
capital facilities. It challenges the generally accepted
belief that there is always a trade between time, cost
and quality.”
– Maximizing value and minimizing waste
– Concurrent engineering of facility and workflow
– Value to owner defined and refined over time
– Continuous flow of work schedules
– Decentralized decision making, transparency, empowerment

16. The 8 Types of Waste
Type of Waste Example
Defects Wrong medication given to patient
Overproduction Specimens delivered in huge batches
Transportation Patient walking football fields between
oncology clinic and chemotherapy
Waiting Patients waiting in E.D.
Employees waiting on work to do
Inventory Expired medications, excess O.R. variation
Motion RN’s walking 5 miles per day
Processing Unnecessary MRI’s when P.T. might work
Human Potential Med Techs recapping specimens

18. Lean Terms
• 5S: Workplace organization and reduction of waste
• Kaizen: continuous improvement
• A3: Format for PDSA problem solving, planning,
reporting
• Kanban: method for replenishment of supplies
• Heijunka: Level loading of workload
• Standardized work: Creating, managing, and improving
processes and protocols
• Value Stream Mapping (VSM)

19. Bad Example of 5S
"We were offering suggestions and getting pushback on safe staffing,
yet being told to reduce the number of pens and pencils.”
– RN (Minnesota)
20. Good Example of 5S for an MD
670 ft for single procedure prep
(pre-Lean walking pattern)

21. Reducing Podiatrist Walking
Restocking Checklist
• Created standardized cart
• Along with standardized rooms,
eliminated the need to leave the room
during patient encounters
23. LEAN – the 7 “sees”
1. See for yourself (“go to the ‘gemba’”)
2. See what people do (observe first hand)
3. See how people spend their time (activity follow sheet)
4. See where people go (spaghetti chart)
5. See what really happens to your patients (value stream
maps)
6. See who your teammates really are (value stream maps)
7. See the wasted effort (waste / ‘muda’)
Applies to design and management
24. Patient-Centered Care
• “Where care comes to you.”
• In the same room:
– lab draws
– nursing assessment
– physician exam
– IV therapy administration
– Music therapy
– Counseling / spiritual care
– scheduling of future
appointments
• “It’s kinda all about you.”
Park Nicollet Frauenshuh Cancer

25. Lean Design Results –
Chanhassen Clinic (PN)
• Decrease walking:
– For patient reduced 27%
– For nurse reduced 27%
– For clinician reduced 42%
• Reduce inventory:
– Reduced 21 exam rooms
– Reduced 1 procedure room
– Reduced construction cost $196,200
– Total project reduction $357,300
• 20% reduction of square footage:
– Created flexibility, team work among disciplines; lean concept of 'open
room'; less steps for patient and staff; improved flow and visual control.

4. Flow of Medications
5. Flow of Supplies
6. Flow of Information
7. Flow of Equipment
8. Flow of Instruments/Processes

31. Seattle Children’s Bellevue
• 32% reduction in original
space estimate Recovery
• Opened on time
• $3.5M under the $70M
budget O.R.
• “Frankly this is the best
“one piece flow” for
ambulatory surgery I Induction Induction
have observed anywhere
in the world.”
– John Toussaint, MD

33. Riley Design Process
• Their lead architect:
– “Building design is often a reaction to their current state”
• Too much equipment – more space --- not the best answer
– “Taking those extra months to understand what they really
wanted and what their ideal state was going to be was very
helpful.”
– Telling architects to not draw anything for 2 sets of user
meetings – strange to them
33
34. Understanding Current State
• 3-day workshops
– NICU
– Burn unit
– Oncology
• Structured observation
by staff members
– Qualitative
– Quantitative

37. Activity Follow
• Shadowing a person
– Focus on the process, not finding fault w/ person
• Identifying tasks / activities done each minute
• Tracking interruptions
• Do spaghetti diagram in parallel
44. Envisioning Future State
• Current: Transporting patients in the burn unit
– Wouldn’t it be great to have a procedure room in the unit?
– Avoid having to go all the way to the O.R.
– “Not dragging that child all the way across the hospital.”
44
46. “Whenever there is
CARE for a
PATIENT, there is a
value stream. The
challenge lies in
seeing it.”
Paraphrasing Rother & Shook
47. What is a Value Stream?
Supplier Customer
Request Made Product or Service
or Need Identified PROCESS STEPS Delivered
Reception Prep Procedure Recovery Reports & Invoice
VALUE STREAM
Value Stream: All steps, both value creating and non value-
creating, required to complete a service from
beginning to end.
47
48. This is a Value Stream Problem
This is Not Always an “ED Problem”
• Beds unavailable
• Admission delays
• Discharge delays
Building a bigger ED might not help
48
49. What is a Value Stream Map?
• A diagram of a process from beginning to end at a
level that people can see interactions between
departments, floors and processes.

50. The Mapping Team
• Create a Cross Functional Team Consisting of:
– VSM Facilitator
• Responsible for leading the team through the VSM process.
– Process Experts
• People who have in-depth knowledge of the Value Stream
you are mapping.
– Process Neophytes
• People who are not familiar with the Value Stream you are
mapping.
51. Go to the “Gemba”
• Cannot be a conference room exercise
• Three versions of a process:
1. What should happen
2. What we think happens
3. What actually happens
• “Gemba” = “actual place,” where the work occurs
55. Types of Future States
• “Ideal” Future State
– Long-term vision
– Dream big – don’t worry about constraints
• “Practical” Future State
– What is achievable in the short to mid-term
59. After the VSMs
• Architect:
• Apply VSM to adjacencies and set based design
• React to what they wanted their ideal state to be, not just problems in
their current state
59
60. Iterations at Riley
• Architect:
– “Use PDCA thinking throughout”
– More detailed room design through each iteration
– Started mockups before we drew anything, based on the ideal
state (the tub room)
60
61. Lean Design Summary
• Goals: Best patient care; best workplace
• You will come up with the best design for your own
Institute
• Time investment
– Staff time
– More planning, longer iteration time
• Payoff
– Faster build (less rework and less cost)
– More likely to have best outcome (from iterative learning)
