What is LEAN?

4 Definition Lean is a methodology of seeking out then removing all the various wastes that restrict the flow of getting services or products to their intended customer Types of Waste Overproduction Waiting Transport Extra processing Inventory Motion Defects Mismanagement of Human Resources

5 Tools to Eliminate Waste Error Proofing Kanban Process Mapping Quick Changeover Shadowing Spaghetti Map Red Tagging Standard Work Value Added Map Waste Walk Visual Control Clearly defined position/job descriptions Eliminate tasks Replace tasks Facilitate tasks Error Proofing Kanban Signals the need to move supplies or product through the process Used to trigger that a process or supply needs to be replenished.

6 Kanban Kanban Flow Chart Process Maps

7 Quick Changeover A method to minimize setup times (switching form one operation or process to the next). Identify all steps Differentiate those steps which are internal to the process and those that could be performed external to the process Standardize Convert internal tasks to external tasks Standardize external processes Examples: Equipment changeover or set up process for a procedure A visual control where an outline or shadow of an object is used as a way to indicate where a tool or other object has been removed and where it should be replaced. Shadowing Spaghetti Map Before Improvements

8 Spaghetti Map After Improvements Red Tagging An effective visual method used to identify items designated for removal from a work area. Red Tagging Cleanup

9 Standard Work Helps to ensure that everyone will be following standard processes and doing the work the same way Standard written procedures Training Communication Posting information where possible visual ques Making it difficult to deviate Process Maps Value Added Maps Waste Walk An exercise to raise staff awareness of the wastes in the practices environment they work in every day.

10 Visual Control The art of placing instruction into the workplace so that anyone knows how to do the right things right, how to keep from doing things wrong, and has the information needed to proceed to the next step. Human Resource Management Are people in the right job titles? Are people performing tasks related to their competency levels? Do position descriptions clearly define roles/core competencies, education/licensure/certification requirements, experience requirements, working conditions, and physical demands?

11 Case Study #1 Using Lean principles to Optimize the Layout of a Flow Cytometry Area in a Cellular Therapy Laboratory Types of Waste Overproduction Waiting Transport Extra processing Inventory Motion Defects Mismanagement of Human Resources Project Background Flow testing performed in 19ft 6in x 14ft 3in space of lab, isolated from main lab Two cytometers located in testing area Plan to purchase an additional one, needed to find a home for it Space not originally designed for flow testing, current layout not ideal

12 Project Goals Design a new layout to accommodate three cytometers and supporting workbenches, equipment Improve efficiency for one person working in the space Make it easy for two people to work in the space simultaneously Make space easily adaptable for future changes Assessing Workflow and Layout using Spaghetti Diagrams Method to visually see workflow and movements within a work area Documented current testing performed on cytometers and additional filing activities Direct observation Team consensus verified standard workflow Started with the specimen entering the process and followed until it left the process Spaghetti Diagrams

13 Discoveries from Assessment Excessive movement when one person utilizes second cytometer Dependent on workload Maintenance of first cytometer Centrifuge located away from main workbench/cytometer Access to the pass through via main area only Becomes crowded with two people present Excessive movement when utilizing second cytometer List of Considerations for the New Layout Workbench/cytometer in close proximity to refrigerator, freezer and centrifuge Need to view cytometer(s) from workbench Supplies need to be in work area Cytometer specific requirements Match future layout to natural flow (from pass through, to refrigerator, to workbench, to centrifuge, to cytometer) Designing the New Layout Brainstormed ideas using scaled paper models of the room and equipment Identified 10+ options for new layout U shape / L shape layouts following natural flow of work Generated pro s / con s list for each option Down selected to best option for future layout Generated 3 D model to confirm layout details and better illustrate planned future layout

14 The Selected New Layout bench low bench fridge flow Flow Entrance/Hallway flow shelving bench bench top main bench centrifuge small freezer flow The Selected New Layout Spaghetti Diagrams of New Layout

15 Feedback on the New Layout Favorite changes: View both instruments at the same time, reducing movement New refrigerator with greater on hand storage, eliminating extra trips to auxiliary storage Least favorite changes: Limited walkway when technologists seated at workstations Successful Completion of Goals New Improve layout accommodates three cytometers and associated benches/equipment efficiency for one person working in the work space Easier for two people to work in the space simultaneously due to two work spaces that can access the pass through Mobile work benches make the area more adaptable for future changes Outcomes from the Project Space avoidance of approximately 46 ft 2 Space required for third flow cytometer Cost avoidance estimated at $54,000 saved Estimated difference to remodel the support area versus a larger remodel of the entire laboratory Improved efficiency Access of pass through Work area matches workflow needs

16 Lessons Learned Clearly document and communicate requirements with others Be flexible with plans and adjust as needed Additional Resources tion/whitepapers/index.html Efficient Laboratory Space Design Special Coagulation Laboratory Layout Improvements lean_manufacturing/lean_manufacturing_layouts.html sigmamaterial.com/workcells.html Many Thanks Amy Mohr Sarah Wittwer Jen Glejf Mike Gustafson Mike Deeds Kevin Bundy Dennis Gastineau, MD Allan Dietz, PhD

17 Case Study #2 Staffing to Workload in a Cellular Therapy Laboratory Types of Waste Overproduction Waiting Transport Extra processing Inventory Motion Defects Mismanagement of Human Resources Project Background Clinical volumes increasing, expected to continue increasing over the next 1 2 years R&D workload growing and must be supported to advance the future of cellular therapy Two clinical technologists lost over 6 month period, need to understand if positions need to be replaced

18 Project Goals Determine if current staffing can cover the workload Identify open capacity throughout the week, utilize that capacity to assist R&D Develop a tool for the future to help assess staffing levels required as workload changes Measuring Current Staffing Divided lab into three categories: management, R&D and clinical Reviewed current staffing schedule to measure available staff for each category By day of week and time of day Management performs some clinical duties Portion of management time assigned to clinical On Call excluded from model but noted Measuring Current Workload Grouped tasks/processes By category (i.e. clinical, R&D, management) By work bench Aid in analysis of required staffing for each category or work bench

19 Measuring Current Workload Collect process timings and calculate average process time for each activity Time study over 4 week period Multiple technologists participated in time study Measuring Current Workload Collect volumes Retrospectively over eight month period By day of week and time of day When work available (not necessarily when completed) Measurements Input into Tool

20 Graphical Output - Day of Week Graphical Output - Time of Day Findings from Analysis Current clinical staff cannot cover workload Two clinical replacement positions requested Analysis used to support the staffing request Specific days/times identified where clinical staff would be available to assist R&D Wednesday, Thursday and Friday Best times from 10AM Noon and 3PM 5PM

21 Flexibility of the Tool Staffing to Workload model built for future staffing analysis and planning Workload changes input into the tool and the tool automatically updates to see staffing impact Ex: volume increases with rwbc testing or R&D patients Use for volume projections Successful Completion of Goals Determined current staffing did not cover the workload; this meant that work was carried over from day to day, overtime was required and management covered the bench more frequently Identified open capacity throughout the week, shared findings with R&D to aid in future planning Developed a tool that can be updated in the future to help assess staffing levels required as workload changes Lessons Learned Make sure to include the following when calculating staffing needs: Planned time away (i.e. PTO, FMLA, etc.) Indirect work such as process improvement projects or continuing education Identify when work is available, not when it is currently performed
