Transcript of "Value stream mapping for non manufacturing environments"

  1. 1. Learning Objectives Participants will learn:  What V l St Wh t a Value Stream Map is – and what it i not. M i d h t is t  Key differences between manufacturing and office/service VSMs.  Best practices for holding a Value Stream Mapping activity.  How to define office & service product families.  Step-by-step approach for creating current and future state maps maps.  How to create an implementation plan from the future state VSM. © 2010 Karen Martin & Associates 2

  7. 7. Why Value Stream Mapping? To set strategy before diving into tactics. t ti  The future state VSM is a macro level blueprint for change; road map Enables us to SEE the process. Promotes s stems thinking / systems seeing the whole  Helps us avoid sub optimizing sub-optimizing © 2010 Karen Martin & Associates 8

  9. 9. Types of Value Streams Product Value Streams Support Value Streams Value Stream “Segments” © 2010 Karen Martin & Associates 10
  10. 10. Types of Value Streams  Product Value Streams  Goods – wide range of manufactured p g products  Services  Healthcare – Emergency department patient flow, surgical patient flow, outpatient testing  Financial Services – credit application process, mortgage process, equipment leasing process  Education – college application to arrival  Repair and maintenance – wind blade repair oil field maintenance repair, maintenance, refrigeration system service and repair  Energy – Nuclear energy production, Oil production  Government – Property tax assessment and processing  Law enforcement – undercover operations, background check process  Military – radar system development, troop deployment  Non-Profit services – Donation processing, disaster aid process  Etc. © 2010 Karen Martin & Associates 11
  11. 11. Types of Value Streams (continued)  Value Stream “Segments”  Order fulfillment  Product development  New account set-up  Laboratory services  Imaging services  Support Value Streams  Recruiting, hiring and onboarding process  Revenue cycle  Information Technology request fulfillment  Purchasing  Accounts payable  Physician credentialing © 2010 Karen Martin & Associates 12
  12. 12. Why Value Stream Mapping? (continued) Shows the linkage between information and material fl i f ti d t i l flow. Makes the disconnects and obstacles t fl b t l to flow visible at a i ibl t macro level Metrics-based d i i making: M t i b d decision ki What are you going to do to affect the numbers? © 2010 Karen Martin & Associates 13
  13. 13. Key Metrics: Time Process time (PT)  The ti Th time it takes to actually perform the work, if one is t k t t ll f th k i able to work on it uninterrupted  Includes task-specific doing, talking, and thinking task specific  aka “touch time,” work time, cycle time Lead time (LT) ( )  The elapsed time from the time work is made available until it’s completed and passed on to the next person or department in th chain d t t i the h i  aka throughput time, turnaround time, elapsed time  Includes Process Time not merely waiting time Time, time. © 2010 Karen Martin & Associates 14
  14. 14. Lead Time vs. Process Time Scenario 1 Lead Time Work Process Time Work passed Received to next step LT = PT + Waiting / Delays g y © 2010 Karen Martin & Associates 15

  16. 16. Summary Metrics: Time Activity Ratio (expressed as a percentage)  The percentage of time anything is being done to the work passing through the system (whether value-adding or non value adding) value adding non-value-adding)  %Act = (∑PT ÷ ∑LT) × 100  100 – %Activity = % Time Work is Idle  Common finding = 1-10%  Could also calculate %VA Activity to show how little time is spent on value-adding activities. © 2010 Karen Martin & Associates 17
  17. 17. Key Metrics: Quality %Complete and Accurate (%C&A)  The percentage of input that’s deemed “usable as is” by the person doing the work  % of incoming work where the downstream customer can perform task without having to “CAC”:  Correct information or material that was supplied  Add information that should have been supplied  Clarify information that should have or could have been clearer  Measured by the immediate downstream customer and all subsequent downstream customers.  Similar to first pass yield in manufacturing manufacturing. © 2010 Karen Martin & Associates 18
  18. 18. Summary Metrics: Quality Rolled First Pass Yield (RFPY)  The percent of value stream output that passes through the process “clean,” with no “hiccups,” no rework required. required  RFPY = %C&A x %C&A x %C&A…  Common fi di = 0 15% C finding 0-15%  Multiply ALL %C&A’s, even if parallel processes © 2010 Karen Martin & Associates 19

  34. 34. Interim Briefings Day 1 – “Here’s what we’ve learned.”  Establishes a mental framework for embracing improvements; “sells” the need for improvement. Day 2 – “Here’s what we plan to do.”  Does anyone object? If so, why? y j y  Challenge policies and paradigms Day 3 – “Here’s how we re going to execute ” Here s we’re execute.  Priorities, approach, timeframes, accountability  Obtain full commitment right then and there there. © 2010 Karen Martin & Associates 35

  44. 44. Preparing to Map Schedule time to go to the Gemba  Prepare frontlines for questions the team will ask; establish a safe haven for them to communicate the true current state (no matter how ugly it is) to high level leaders they may not usually interface with.  No written procedures allowed – creates bias toward communicating what should h i ti h t h ld happen rather th what th than h t does happen. © 2010 Karen Martin & Associates 45
  45. 45. Preparing to Map (continued) Draw map manually!  11 x 17” paper  Or 36” wide plotter paper and 3 x 6” post-its for process blocks (my preference) Only convert to electronic medium if absolutely necessary (e-distribution, training, etc.) (e distribution,  iGrafx FlowCharter (my preference)  Systems2Win – Excel-based y  Minitab  e-VSM  Others © 2010 Karen Martin & Associates 46
  46. 46. Step 1 Label your map (draw manually or use 36” wide plotter paper and 3 x 6” post-its)  Value stream name  Current or future state  Customer demand (volume of work p time ( per period)  Takt time (if relevant)  Date  Facilitator’s name (and/or team) ( ) © 2010 Karen Martin & Associates 47

  48. 48. Step 2  Identify all blocks in the process (target 5-15 blocks)  Customer icon is placed in upper right or middle  Upper right if supplier exists (supplier is placed in upper left)  Middle position if a separate supplier doesn’t exist  Supplier (if relevant) is placed in upper left  Each block (post-it) contains an activity or group of activities that occurs before a break in the timeline occurs - typically a handoff to another function/work team team.  Activity format is verb/noun – what happens to what  Include the function who performs the task  Include number of workers who perform the task  Include any obstacles to flow – batches, shared/inaccessible resources, system downtime, etc.  Consider walking the process © 2010 Karen Martin & Associates 49

  50. 50. Step 3 Identify all I.T. systems used in the process and information flow  For most VSMs, these are placed above the process blocks  In very complicated VSMs with two rows of process blocks, I.T. systems can be placed between the rows, if necessary.  Note N t any scheduling th t occurs ( h d li that (rare i in current state)  Who tells h Wh t ll whom t d what? to do h t? © 2010 Karen Martin & Associates 51
